In their review "Functions and interaction of plant lipid signalling under abiotic stresses" the authors Liang, Huang, Liu, Chen and Li describe the metabolism of plant lipids and discuss their involvement in plant responses to abiotic stress. Thereby they also provide necessary background for further research on the interactions between plant lipids and abiotic stress. Several summary diagrams as well as a comprehensive model of interactions between plant lipids and abiotic stresses is summarized in a graph.

Findings on rice tapetum development, including genomic, transcriptomic and proteomic studies are reviewed by the authors Tariq, Yaseen, Xu, Rehman, Bibi and Uzair. They also describe tapetal programmed cell death (PCD), sporopollenin biosynthesis, ROS activity for tapetum
function and its role in male reproductive development. They summarize the role of the tapetum in male fertility using rice as a model system, and provide information that can be applied in rice hybridization and that of other major crops.

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.

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.

Authors Diamond, Barnabé and Desgagné-Penix raise questions on the interpretation of data obtained from the technique used and on the true localization of the biosynthetic enzymes in V. planifolia. They discuss the findings surrounding the cellular-localization and activity of enzymes of vanillin biosynthesis. This will help to further understand the pathway and urge for additional research study to resolve the current debate in the biosynthesis of the most popular flavor compound in the world.

Author Garmash in the review with the title "Suppression of mitochondrial alternative oxidase can result in upregulation of the ROS scavenging network: some possible mechanisms underlying the compensation effect" proposes that the decrease in the relative amount of reduced ascorbate at stable ROS levels as a result of compensation in AOX1a-suppressed plants is a sign of stress development.

Based on the current experimental advances authors Pradhan, Panda, Bishi, et al. in their review "Progress and prospects of C4 trait engineering in plants" summarize novel biotechnological crop improvement strategies that might help to incorporate C4 photosynthetic traits into C3 crops for sustaining food, fiber and fuel production around the globe. They not only report on successes but also on failures and highlight the pros and cons of using rice as a model plant for short-, medium- and long-term goals of genetic engineering.

In their review "Arbuscular mycorrhizal fungi: Effects on secondary metabolite accumulation of traditional Chinese medicines", the authors Ran, Ding, Cao et al. discuss the effects of arbuscular mycorrhizal fungi on secondary metabolites in Traditional Chinese medicine and the mechanism of arbuscular mycorrhizal fungi regulating the biosynthesis of secondary metabolites. The results could be used to provide new ideas and methods for improving the quality of Traditional Chinese medicine.

In their review "Advances in physiological mechanisms of selenium to improve heavy metal stress tolerance in plants" the authors Lai, Yang, Rao et al. summarize several antagonistic effects of selenium on heavy metal stressors such as cadmium and mercury. The review helps to comprehensively understand the physiological mechanism of selenium in plant tolerance to heavy metal stress of plants, and provides theoretical support for the practical application of selenium in environmental remediation and agricultural development.

In their research paper "Central European 2018 hot drought shifts scots pine forest to its tipping point" published in July 2022 authors Haberstroh et al. analyse the severe negative impacts of the hot drought in 2018 on a Pinus sylvestris forests in southwest Germany. The co-occurrence of unfavourable site-specific conditions with recurrent severe droughts resulted in accelerated mortality. Thus, the 2018 hot drought pushed the P. sylvestris stand towards its tipping point, with a subsequent vegetation shift to a broadleaf-dominated forest. To draw this conclusions the authors had analysed needle water potential, carbon assimilation and volatile organic compound (VOC) emissions. The impact and recovery were assessed as ecosystem carbon exchange, normalized difference vegetation index (NDVI) from satellite data and tree mortality data.

From the data measured and published in their paper "Seasonal shifts in isoprenoid emission composition from three hyperdominant tree species in central Amazonia" Gomes Alves and the 12 other authors suggest that emission composition shifts are part of a plastic response to increasing abiotic stress (e.g. heat and drought) and reduced photosynthetic supply of substrates for isoprenoid synthesis. They emphasize that future focus should be put on emission composition shifts that are part of a plastic response to increasing abiotic stress (e.g. heat and drought) and reduced photosynthetic supply of substrates for isoprenoid synthesis.

In their review "Glutamine synthetase: an unlikely case of functional redundancy in Arabidopsis thaliana" the authors Moreira, Coimbra and Melo integrate analyses on the likely roles of the distinct cytosol- and plastidlocated Glutamine synthetase (GS) isoenzymes in the model plant, highlighting the redundancy of the GS gene family specifically occurring in this plant. This is in contrast to GS isoenzymes that were observed in nitrogen metabolism in species like Oryza sativa and Zea mays.

A growing body of evidence indicates potential role of H₂S in plant defence, particularly against bacterial and fungal pathogens. Recent studies suggested that the gaseous signalling molecule participates in plant defence potentially by

1. regulating glutathione metabolism,
2. inducing expression of pathogenesis-related (PR) and other defence-related genes,
3. modulating enzyme activity through post-translational modifications, and
4. interacting with phytohormones such as jasmonic acid, ethylene and auxin.

The authors Choudhary, Singh, Khatri, and Gupta discuss the biosynthesis, metabolism and interaction of H₂S with phytohormones, and highlight evidence gathered so far to support the emerging roles of H₂S in plant defence against invading pathogens.

Since signalling molecules like hydrogen sulfide (H₂S) play a crucial role in mitigating the adverse effects of environmental stresses in plants it is important to understand the several physiological and biochemical mechanisms. The authors review recent advances in understanding the beneficial roles of H₂S in conferring multiple abiotic stress tolerance in plants. And discuss the interaction and crosstalk between H₂S and other signal molecules and highlight some genetic engineering-based current and future directions.

In their review the authors Tyagi, Sharma, Ali, and Gaikwad summarize the crosstalk of the important plant signalling molecules hydrogen sulphide (H₂S) and nitric oxide (NO) during waterlogging stress in legumes, which are emitted from plants and soil microbes and that are known to regulate key physiological pathways. They provide an overall summary on H₂S and NO, including biosynthesis, biological importance, crosstalk, transporter regulation as well as understanding their role during waterlogging using ‘multi-omics’ approach.

In his viewpoint paper Author Lamont asks for caution against the routine use of end-of-trial germination and viability of ungerminated seeds as an estimate of initial viability in determining germination success of various treatments. He analyses Leucadendron species and in his paper also explores ways to deal with the problem and to preference estimates of initial viability to be undertaken on a separate sample of seeds concurrently with the experiment as this avoids the risk of seed death during the trial.
