Special Issue Information

Dear Colleagues,

Embarking on a nuanced exploration of plant stress responses, the forthcoming Special Issue promises a deep dive into plant adaptation processes. This collection of scientific contributions, exploring plants from various corners of the world, aims to unravel the intricate molecular events that coordinate plant responses to a range of stressors, utilizing advanced omics profiling techniques.

Leading experts in the field contribute cutting-edge research spanning genomics, transcriptomics, proteomics, metabolomics and other omics tools. These approaches unveil a holistic understanding of the molecular mechanisms that empower plants to withstand environmental challenges. From climate-induced stress to encounters with pathogens, each article within this Special Issue sheds light on the intricacies of plant stress adaptation. We also welcome literature reviews that synthesize valuable information on the “omics + plants + stress response” topic.

This Special Issue is poised to be a great resource for researchers, providing a comprehensive overview of the latest advancements in omics profiling and its implications for deciphering and enhancing plant resilience. Join us in unraveling the molecular tapestry that defines the resilient nature of plants, shaping the future of plant science and its applications.

Plants reprogramme their proteome to alter cellular metabolism for effective stress adaptation. Intracellular proteomic responses have been extensively studied, and the extracellular matrix stands as a key hub where peptide signals are generated/processed to trigger critical adaptive signal transduction cascades inaugurated at the cell surface. Therefore, it is important to study the plant extracellular proteome to understand its role in plant development and stress response. This study examined changes in the soluble extracellular sub-proteome of sorghum cell cultures exposed to a combination of sorbitol-induced osmotic stress and heat at 40 °C. The combined stress significantly reduced metabolic activity and altered protein secretion. While cells treated with osmotic stress alone had elevated proline content, the osmoprotectant in the combined treatment remained unchanged, confirming that sorghum cells exposed to combined stress utilise adaptive processes distinct from those invoked by the single stresses applied separately. Reactive oxygen species (ROS)-metabolising proteins and proteases dominated differentially expressed proteins identified in cells subjected to combined stress. ROS-generating peroxidases were suppressed, while ROS-degrading proteins were upregulated for protection from oxidative damage. Overall, our study provides protein candidates that could be used to develop crops better suited for an increasingly hot and dry climate. Full article
