Summary: SUB1A, an ethylene-responsive transcription factor gene, plays a role in regulating the restricted elongation of uppermost leaves in response to submergence in rice. This study investigates the molecular and physiological functions of SUB1A in mature and growing leaves under submergence. The results show that SUB1A modulates different sets of hormonal pathways, contributing to distinct adaptive responses in mature and growing rice leaves.

Summary: Rice is a staple food for most of the world's population, but drought negatively affects its yield. This study identified stable QTLs for drought tolerance in rice and conducted a meta-QTL analysis for use in breeding programs. The identified genes can be used in molecular breeding and genetic engineering for drought resistance in rice.

Summary: The study found that sugar-mediated osmotic acclimation and strong antioxidative response can reduce drought-induced biomass loss in rice at the vegetative stage. Different metabolic and antioxidant adaptations confer drought tolerance to aerobic and upland rice varieties, with varying effectiveness at different developmental stages. Unraveling the genetic control of these mechanisms may be valuable in breeding new rice varieties adapted to water-limited environments.

Summary: In this study, a novel drought-sensitive mutant named dsm3 was identified in rice and the recessive gene Osdsm3 responsible for the withered leaf tip phenotype was cloned and characterized. The mutation in the candidate gene LOC_Os01g10680 was found to lead to premature translation termination. Furthermore, high expression of OsDSM3 in certain tissues and upregulation of drought-stress-related genes under drought conditions were observed. The discovery of Osdsm3 holds promise for further investigation into the molecular mechanisms underlying rice drought resistance.

Summary: The anatomical and architectural phenotypes of rice roots were examined to understand their responses to drought stress. The study found that the plasticity of root phenotypes in Azucena contributes to its drought tolerance by reducing the metabolic cost of soil exploration and improving water transport efficiency.

Summary: This study investigated the mechanisms of salt adaptation in salt-tolerant rice HD961 at the early seedling stage using transcriptome and metabolome analysis. The results showed that HD961 exhibited stronger growth and antioxidant capacity under salt stress compared to 9311. The analysis revealed that glutathione metabolism played a critical role in HD961's response to salt stress. Intensive regulation of related genes and metabolites may contribute to the salt resistance in HD961.

Summary: Research has shown that the rice gene OsCCR10 is directly activated by the transcription factor OsNAC5, mediating drought tolerance through lignin accumulation. Overexpression of OsCCR10 in transgenic rice plants results in improved drought tolerance and higher lignin content, while knockout mutants exhibit reduced lignin accumulation and drought tolerance. Transgenic rice plants with root-preferential overexpression of OsCCR10 also show higher grain yield under field drought conditions, indicating the importance of lignin biosynthesis in drought tolerance.

Summary: This study identified a novel drought tolerance induced gene OsWIH2 in rice, overexpression of which significantly improves rice drought tolerance. It was found that the drought-inducible transcription factor OsbHLH130 can activate the expression of OsWIH2, leading to decreased water loss rate and ROS accumulation under drought stress.

Summary: This study identified bZIP72 as a positive regulator of seed germination under submergence in rice, enhancing both submerged seed germination and coleoptile elongation. Through binding to the promoter of alcohol dehydrogenase 1 (ADH1) and enhancing its activity, bZIP72 increases the production of energy reserves for alcoholic fermentation and glycolysis, ultimately conferring tolerance to submergence.

Summary: Drought is a major threat to crop plants like rice globally. Guard cells in rice plants play a crucial role in responding to drought, with physiological analysis revealing decreased photosynthesis and stomatal conductance under drought stress. Drought-responsive proteins were identified, showing a positive relationship between protein abundance and gene expression, while DNA methylation levels also played a role in plant adaptation to water-deficit conditions and stress memory.

Summary: Glutaredoxin 3 (Grx3) is a redox protein that maintains structural integrity and glutathione (GSH) binding capabilities across different temperatures. This study investigates the roles of specific bonds in Grx3's structure and function, and how psychrophilic Grx3 variants adapt to cold environments. The highly conserved Arg51-Asp69 salt bridge and Gln56-His63 hydrogen bond are crucial for stabilizing the structure and catalytic activity of Grx3. Psychrophilic variants of Grx3 have adapted to cold environments by reducing GSH binding and increasing structural flexibility.

Summary: The pathogenesis of prion diseases involves the transformation of prion protein into an insoluble form. This study found that two phage chaperonins can promote the fibrillation of prion protein in an ATP-dependent manner, resulting in the formation of less toxic large clusters. These fibrils differ in morphology and properties from those formed spontaneously in acidic pH with denaturants.

Summary: Magnesium is an important divalent cation for regulating enzyme activity. The binding of Mg2+ through the PAS domain inhibits phosphoglycerate kinase (PGK) activity in LmPAS-PGK at neutral pH, but PGK activity is derepressed at acidic pH. Mutation studies revealed that the Asp-4 residue is crucial for Mg2+ binding at neutral pH.
