Special Issue Information

Dear Colleagues,

Given the ever-growing world population and considering the climate change crisis that is currently unfolding, we strongly believe that it is timely to discuss the challenges and opportunities of the effect of stress conditions on crop yields. As sessile organisms, plants must cope with abiotic stress (soil salinity, drought, and extreme temperatures) and biotic stress (nematode and pathogenic bacteria infection). In addition, the efficiency of water and fertilizer systems also plays a crucial role in improving crop yield. With this Special Issue, we aim to compile the latest knowledge on plant responses to biotic and abiotic stresses and to highlight the shortcomings and knowledge gaps in our understanding of the underlying processes. Based on this, we will lay the groundwork for future research that can contribute to this important field of plant science.

Heat stress is a critical environmental challenge that disrupts rice growth, development, and productivity and poses a significant threat to global food security. The CCR4-NOT protein complex, particularly its CCR4-associated factor 1 (CAF1) subunit, plays a crucial role in the dynamic regulation of gene expression by mediating mRNA de-adenylation, a key step in mRNA degradation and turnover. However, the specific function of OsCAF1 proteins under heat stress in rice remains poorly understood. In this study, we investigated the dynamic subcellular localization of OsCAF1A in response to elevated temperatures and its role in heat stress tolerance. Under normal conditions, OsCAF1A is diffusely localized to the cytoplasm. However, OsCAF1A predominantly localizes to processing bodies (PBs) under heat stress. The results of interaction studies revealed that two DEAD-box RNA helicases, OseIF4AIIb and OsRH8, modulate the re-localization of OsCAF1A, by OseIF4AIIb inhibiting and OsRH8 promoting its association with PBs during heat stress. Furthermore, OsCAF1A mRNA was more abundantly expressed in rice seedlings than other OsCAF1 genes and is further upregulated by high temperature. The overexpression of OsCAF1A significantly enhanced heat tolerance, whereas mutants exhibited increased heat sensitivity. These findings underscore the potential of OsCAF1A as a tool to improve crop resilience to climate change. Full article

Acid invertases (Ac-Invs) are crucial enzymes in plant physiology, regulating sucrose metabolism and hydrolyzing sucrose into glucose and fructose. These sugars serve not only as energy sources and structural components but also as signaling molecules, influencing diverse developmental processes, including seed and fruit growth, flowering, and stress responses. Ac-Invs are classified into cell wall invertases (CWINs) and vacuolar invertases (VINs) based on their subcellular localization, with both playing distinct roles in sucrose unloading, osmotic regulation, and sugar accumulation. Recent studies have also highlighted their involvement in abiotic stress adaptation and hormonal regulation, emphasizing their central role in plant resilience and productivity. However, gaps remain in understanding their regulatory mechanisms, particularly their interactions with plant hormones, defective invertases, and responses to environmental stresses. This review summarizes the biochemical characteristics, functions, and regulatory mechanisms of Ac-Invs, providing insights into their evolutionary significance and potential applications in crop improvement. Future research directions are proposed to elucidate unresolved questions and leverage Ac-Invs for enhancing agricultural sustainability. Full article
