The 19th Plant Science Student Conference (PSSC 2024) took place at the Leibniz Institute of Plant Biochemistry (IPB) from June 17th to 20th in 2024. The conference represents almost two decades of tradition between the IPB and the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK), in which students at the institutes invite other students of the plant sciences to share their knowledge, build connections and experience an academic conference in a student-friendly atmosphere. Approximately 60 PhD students participated this year, joining not only from IPB and IPK, but also from the Martin Luther University Halle-Wittenberg (MLU). In addition, the conference invited Prof. Dr. Gabriel Schaaf from the Rheinische Friedrich Wilhelms University Bonn, Dr. Marie Barberon from the University of Geneva and Prof. Dr. Stefanie Ranf-Zipproth from the University of Fribourg as keynote speakers. As part of the organizing team Max Jonas Paulmann, Lilly Eger, and Jolina Marx from IPB report participants spent four exciting days full of inspiring science, fruitful interaction and – of course – delicious food.

Unser Ehrenmitglied, der Evolutionsforscher, Pionier der Karyotaxonomie, Lehrbuchautor und Initiator der Florenkartierung Mitteleuropas, Professor Friedrich Ehrendorfer, ist am 28. November 2023 im 97. Lebensjahr gestorben. Ehrendorfer klärte an der Universität Wien nicht nur die komplexe Evolution und Verwandtschaft unter Labkräutern und Rötegewächsen mit multidisziplinären Ansätzen auf, sondern verfasste mehr als 200 Publikationen und zwei Kapitel in Strasburgers Lehrbuch der Botanik. Er vertiefte sich bereits in taxonomische Fragestellungen auch wenn diese Fachrichtung seinerzeit als unseriös galt und erst später Anerkennung erfuhr. Die Exkursionen des Pflanzenkenners waren bei den Studierenden beliebt, erinnert Ehrendorfers Mitarbeiter, der Taxonom Prof. Manfred A. Fischer in seinem Nachruf. Ehrendorfer erhielt mehrere Auszeichnungen für sein wissenschaftliches Werk, das in seinen zahlreichen Publikationen und in den von ihm ausgebildeten Taxonominnen und Taxonomen weiterlebt.

To celebrate the 200th birthday of the phycologist Nathanael Pringsheim (30 November 1823 – 6 October 1894), the Matthias-Schleiden-Institute at the University of Jena, where Pringsheim was a professor for around four years, held a symposium on 19 December. In her introductory remarks, phycologist Professor Dr Maria Mittag placed Pringsheim in the ranks of the Institute's outstanding professors. DBG's president, Professor Dr Andreas Weber, reported on the history of our German Society for Plant Sciences (DBG), which Pringsheim founded in Berlin in 1882, under the title "From 1882 to 2023: 141 years of promoting plant science". Pringsheim led our society until his death in 1894. He was instrumental in the transition from an association into a scientific society [1]. Professor Dr Andreas Deutsch introduced the sexual revolution in algal research in citing important scientific findings that Pringsheim elicited from algae: "Nathanael Pringsheim was able to observe how male gametes swam towards female egg cells and united with them in an inconspicuous alga. This discovery, made in 1855, was a scientific sensation," Deutsch writes in his latest book [2]. This was the first direct observation of the fertilisation process in a living organism.

The Wilhelm Pfeffer Foundation of our German Society for Plant Sciences (DBG) awards Dr. Prathiba Kumari the Prize for the best plant science publication, which is endowed with 1,000 Euros. "In the published work, Dr. Kumari has identified a class of proteins that govern the correct positioning of the cell plate during cytokinesis and thus play a key role in plant cell division”, the board of the foundation explains its decision. These IQD proteins are linked to the cytoskeleton of plant cells and are part of a navigation system that coordinates the spatial control of cell division. Consequently, plants lacking these IQD proteins display chaotically arranged plant cells. With her article published in the journal Nature Plants (IQ67 DOMAIN proteins facilitate preprophase band formation and division-plane orientation DOI: 10.1038/s41477-021-00923-z), Dr. Kumari from the working group of Dr. Katharina Bürstenbinder from the Leibniz Institute of Plant Biochemistry in Halle, Germany, has significantly expanded our understanding of cell division in the model plant Arabidopsis thaliana and thus of plant growth and development. Dr. Kumari, who is currently conducting plant research as a PostDoc at the Umeå Plant Science Centre at the Swedish University of Agricultural Sciences (SLU), will be awarded the certificate in 2024 at the next International Conference of our German Society for Plant Sciences in Halle, Germany; the plant scientist already received the prize money by now.

Umfrage zeigt hohen Bedarf an Freilandstudien mit gentechnisch veränderten Pflanzen

Abbildung 1: Häufigkeit der Pflanzenarten oder Pflanzengattungen, die in Freilandstudien untersucht werden sollten. Insgesamt wurden 229 Antworten gegeben. Die Kategorie Bäume umfasst Pappel, Fagus, Picea und Sequoiadendron.

Eine online-Befragung unter Pflanzenwissenschaftler*innen in Deutschland zeigt großen Bedarf an Freilandstudien mit gentechnisch veränderten Pflanzen. Nur mit Studien im Freiland lassen sich aussagekräftige Ergebnisse z.B. zur Ertragsbildung sowie Klima- und Stresstoleranz gewinnen. Vor gezielter Zerstörung gesicherte Freilandflächen (sog. Protected Sites) sind ein Lösungsansatz. Für 83 Prozent der Teilnehmer*innen an der Umfrage eröffnen sich damit neue Forschungsperspektiven. Die Einrichtung solcher zerstörungssicheren Freilandflächen kann die internationale Konkurrenzsituation der Pflanzenwissenschaften in Deutschland grundlegend verbessern. Dies ist wichtig, weil derzeit auch genomeditierte Pflanzen unter die Regularien des Gentechnikgesetzes fallen. Deshalb besteht dringender Handlungsbedarf  ̶̶  unabhängig von einer zukünftigen, an den Stand wissenschaftlicher Erkenntnis angepassten Neuregulierung genomeditierter Pflanzen in der EU.

Open Statement on the Regulation of Genome Edited Plants and Crops

The EU and New Zealand differ from most other countries and their regulations for precision breeding techniques (see Schmidt, Belisle, Frommer (2020), EMBO Rep 2020, e50680, https://doi.org/10.15252/embr.202050680)

132 European research institutes and science associations – with DBG being one of them - strongly recommend to the European Council, European Parliament and the European Commission to revise the existing directive for precision breeding, also known as genome editing. This is not only important for recovery from the COVID-19 crisis but also since genome-editing offers many solutions for a fast, relatively simple and much more directed way to create resilience to climate change compared to previous breeding techniques. Moreover the breeding of plants that are less dependent on fertilizers and pesticides is more efficient. Use of these methods preserves natural resources of our planet and supports to achieve the Sustainable Development Goals of the United Nations as well as the Green Deal of the EU. The European Sustainable Agriculture through Genome Editing (EU-SAGE) Network, under which the institutions named above are unified, recommends the European Commission to endorse this message for the benefit and welfare of all EU citizens and to adapt the current regulations to use genome-editing for crop and plant breeding to recent scientific results. In its Open Statement the EU-SAGE network cites scientific studies that demonstrate the successful creation of genome-edited plants with resilience to climate change and resistance against pests and diseases and therefore higher yields and revenues. Other studies have proven to reduce the dependency on pesticides by improving resistance against diseases in rice, wine, wheat, and grapefruit. In addition precision breeding accelerates the introduction of healthy traits into vegetables and fruits, as studies have shown.

Review: past 200 year timeline and modelled future rate of expansion of Scotch broom

A timeline of Scotch broom’s global expansion highlights threats to ecological processes and the need for an enhanced monitoring program.

Cytisus scoparius (L.) Link, commonly referred to as Scotch broom, is a Mediterranean shrub capable of thriving in a variety of ecosystems that has invaded every habitable continent on Earth. The authors PW Hacker and NC Coops here present a timeline and estimated rate of expansion from 1816 to 2016. They also model its expected range over the next 70 years, and highlight the need for investigation into its expansion mechanisms and the establishment of monitoring programs.

Review: Water for agriculture - more crop per drop

The scarce resource water is vital for agriculture, serving multiple functions in biomass growth, and improving water use efficiency is crucial in crop production.

It is challenging to maintain high crop yields, even in arid and drought-prone regions that depend on irrigation. In this review authors Geilfus, Zörb, Jones, Wimmer & Schmöckel explain water use efficiency (WUE) and options to improve water use and thus crop yield. Nutrient management might represent another possibility to manipulate water uptake and use by plants. An emerging topic involves agroforest co-cultivation, where trees in the system facilitate water transfer through hydraulic lift, benefiting neighbouring crops. Other options to enhance crop yield per water use are also discussed.

New Method: lifetime mesophyll conductance

Mesophyll conductance integrated over the lifetime of the leaf is calculated from the isotopic composition of epicuticular wax harvested separately from the adaxial and abaxial sides of hypostomatous leaves and can be partitioned into gas and liquid phases.

Breeding of new plant varieties with lower mesophyll resistance for CO2 diffusion requires knowledge of its diffusion components. Authors Janová, Kubásek, Grams, Zeisler-Diehl, Schreiber & Šantrůćek therefore tested a new method to estimate relative drawdowns of CO2 concentration across hypostomatous leaves of Fagus sylvatica integrated over the lifetime of the leaf. The new method shows that intercellular components is minor but not negligible part of CO2 diffusion and reflects leaf anatomy traits, i.e. leaf mass per area and thickness.

CRISPR‐Cas9 and beyond - review summarizes target genes for developing disease‐resistant plants

Genome-editing technology is a promising strategy for protecting food security against yield losses of crops due to unpredictable climate change and plant diseases.

In their paper the authors Park et al. provide a brief overview of recent progress in genome-editing technologies, including zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (Cas9) technologies. They classify disease resistant mutants of Arabidopsis thaliana and several crop plants based on the roles or functions of the mutated genes in plant immunity and suggest potential target genes for molecular breeding of genome-edited disease-resistant plants. Genome editing technologies are resilient tools for sustainable development and promising solutions for coping with climate change and population increases.

Review: the world’s largest mimicry system

Mimics of pollen, anthers, stamens, and androecia, their models and pollen eating bees and hoverflies constitute the world’s largest mimicry system.

In the open access paper "pollen, anther, stamen, and androecium mimicry" authors Lunau, De Camargo and Brito review the hypotheses, why the yellow UV-absorbing floral centre is so frequent in angiosperms. They review the pollen, anther, stamen, and androecium mimicry (PASAM) hypotheses, present new and published data on pollenating and pollen-collecting pollinators’ responses to PASAM structures and discuss how widespread these systems are around the globe. Their ultimate goal is to promote the idea that PASAM is a plausible first approach to understanding floral colour patterns in angiosperms.

Review: Mycorrhization in trees - ecology, physiology, and emerging technologies

Mycorrhization in trees impacts ecological and physiological dynamics of a forest ecosystem.

The paper summarizes the ecological and physiological significance of mycorrhization. As the authors Chaudhury et al. describe: Dual mycorrhization relationships in trees and even triple relationships among trees, mycorrhizal fungi and bacteria offer an interesting physiological system to understand how plants interact with other organisms for better survival. Besides, studies indicate additional roles of mycorrhization in learning, memorizing and communication between host trees through a common mycorrhizal network (CMN). Recent observations in trees suggest that mycorrhization may even promote tolerance to multiple abiotic (e.g., drought, salt, heavy metal stress) and biotic (e.g. fungi) stresses. Due to the extent of physiological reliance, local adaptation of trees is heavily impacted by the mycorrhizal community. This knowledge opens the possibility of a non-GMO avenue to promote tree growth and development. Indeed, mycorrhization could impact growth of trees in nurseries and subsequent survival of the inoculated trees in field conditions.

Review on allelopathy and allelobiosis: efficient and economical alternatives in agroecosystems

The paper summarizes allelopathy and allelobiosis in inter-specific, intra-specific, plant-microorganism, and plant-insect context, and discusses the involved substances, their mechanisms, as well as environmental factors influencing allelopathic/signal molecule production and spread.

In their review authors Han et al. summarize and classify allelochemicals and chemical signals according to their function and structure in relation to environmental factors and generation and diffusion of such signals, since allelopathy and allelobiosis have never been systematically described thus far. Moreover the authors provide recent research on the application of allelopathy and allelobiosis in agroecosystems in future studies.

Review: Oxygen transport in plants under hypoxia/anoxia - diffusion and convection

In waterlogged environments, plant root aeration mainly relies on diffusion through aerenchyma, although some emergent and floating-leaved plants utilize pressurized flows to facilitate gas movement within their stems and rhizomes

In the article "An overview of oxygen transport in plants: diffusion and convection" author G. G. Striker summarizes how plants under hypoxia/anoxia ensure a steady oxygen supply to their cells and identifies three types of pressurized (convective) flows: humidity-induced pressurization (positive pressure), thermal osmosis (positive pressure with air flow against the heat gradient), and venturi-induced suction (negative pressure) caused by wind passing over broken culms.

Review: Divergence of non-flying mammal-pollinated plants

The pollination system and evolutionary transition of Mucuna in Asia are unique, reflecting the divergence of the non-flying mammal-pollinated plants

In the article "Evolution of a non-flying mammal-dependent pollination system in Asian Mucuna (Fabaceae)" author S. Kobayashi summarizes the available knowledge of pollination in Asian Mucuna (Fabaceae), a genus mainly distributed in the tropics, and discusses the evolution of plants pollinated by non-flying mammals in Asia. Nineteen pollinator species have been recorded and pollination systems have been categorized into four types. An examination of the relationship between Mucuna species and their pollinators from the lineage perspective revealed that all species in Mucuna, subgenus Macrocarpa, which are distributed in Asia, are pollinated exclusively by non-flying mammals, f.e. from squirrel species.

Review: Plant water uptake modelling - added value of cross-disciplinary approaches

Factors influencing water uptake and complementary interdisciplinary hybrid models of plant water uptake

The authors Dubbert, Couvreur, Kübert, and Werner summarize how interdisciplinary hybrid plant water uptake models add the value of a broader conceptual view of soil-plant feedbacks of water, nutrient and carbon cycling. The main goal is to highlight how the four dominant model approaches can be and have been used to create interdisciplinary hybrid models enabling a holistic system understanding that also embeds plant water uptake plasticity into a broader conceptual view of soil–plant feedbacks of water, nutrient and carbon cycling, or reflects observed drought responses of plant–soil feedbacks and their dynamics under, that is, drought.

Review: Grass species with smoke-released seed dormancy: A response to climate and fire regime but not photosynthetic pathway

Among worldwide grass species, four types of smoke-assisted seed dormancy release can be recognized, based on % with C4 photosynthesis, vegetation type, rainfall seasonality, and type and frequency of fire

In the review author Lamont summarizes the worldwide literature for reports on germination responses among grasses, whose photosynthetic pathway was known, to treatment by smoke and obtained information for 217 species and 126 genera. Thus, even though C3 and C4 grasses are equally capable of expressing smoke sensitivity, their response depends on the region’s climate and fire regime that also dictate which photosynthetic pathway dominates.
