Summary: Plant growth-promoting rhizobacteria (PGPR) can enhance plant growth, salt tolerance, and physiological performance. This study found that PGPR inoculation improved the energy use efficiency, ion profile balance, and photoprotection ability of Halimione portulacoides plants under salt stress. These findings highlight the importance of bioaugmentation in promoting plant fitness and improving salt tolerance, with great potential in biosaline agriculture and salinized soil restoration.

Summary: Jasmonate has dual impacts on the osmotic and ionic components of salt stress in rice. It is required for abscisic acid-mediated water deprivation responses but inhibits Na(+) retention in roots, leading to leaf damage. This study investigates the dynamics of JA metabolism and signaling in rice and identifies contrasted contributions of JA signaling to different sectors of the salt stress response in the plant.

Summary: This study identified 59,948 expressed genes from major vegetative tissues of Eucalyptus through transcriptome sequencing. The key gene families involved in GA biosynthesis, degradation, and signaling were investigated and compared with other plants. Analysis of gene expression patterns showed diverse responses to abiotic stresses. Overexpression of EguGA20ox1 and EguGA20ox2 in Arabidopsis promoted vegetative growth but increased sensitivity to stress, while EguGA2ox1 overexpression enhanced stress resistance. Overexpression of EguGA20ox in Eucalyptus roots accelerated hairy root growth and improved xylem differentiation. This study provides comprehensive insights into GA metabolism and signaling genes in Eucalyptus and identifies their role in growth, stress tolerance, and xylem development, benefiting molecular breeding efforts.

Summary: This study reveals the crosstalk mechanism between methyl jasmonate and abscisic acid signaling in regulating water use efficiency and drought stress tolerance in Populus euphratica. By conducting molecular experiments and phenotype analysis, it was found that PeJAZ2 acts as a positive regulator in MeJA and ABA signaling, enhancing drought tolerance and water use efficiency in poplar through ABA-induced stomatal closure and hydrogen peroxide production.

Summary: This study reveals the critical role of a JA-responsive glutathione S-transferase gene (SlGSTU24) in alleviating cold stress in tomato. SlGSTU24 is expressed in all tissues and is responsive to both JA and cold stress. Upregulation of SlGSTU24 attenuates cold-induced oxidative stress, while its expression is dependent on the crucial regulator of JA signaling pathway, SlMYC2. These findings uncover a crucial module MYC2-SlGSTU24 that maintains ROS homeostasis in tomato under cold conditions.

Summary: This study analyzed the transcriptome response of root tips to water stress in two rice genotypes, IR64 and Azucena. The results showed molecular differences in root growth responses to water stress between the two genotypes. Azucena enhanced growth and root exploration, while IR64 relied on cell insulation and antioxidant system to withstand stress.

Summary: This study investigated the effects of toxic cyanobacteria and thermal stress on the edible bivalve Corbicula fluminea. The results showed that these stressors significantly influenced the oxidative stress responses of the bivalves. The differentially expressed genes were found to be associated with oxidative stress, immune functions, and metabolic functions.
