Tomato ( L.) is a major economic vegetable crop globally, yet it is prone to gray mold disease caused by infection during cultivation. Caffeoyl shikimate esterase (CSE) is a crucial component of the lignin biosynthesis pathway, which significantly contributes to plant stress resistance.

In rice, the inactivation of endogenous bioactive GAs and their precursors by GA 2-oxidases (GA2oxs) regulates stem elongation and reproductive development. However, the regulatory mechanisms of GA2ox gene expression, especially in rice reproductive organs, are unknown.

Although the WRKY proteins in and other species have been thoroughly investigated, there has been relatively little research on the WRKY family in , which is one of the most widely grown vegetables in China. In this study, we performed a genome-wide analysis to identify genes, which were subsequently classified and examined in terms of their gene structures, chromosomal locations, promoter cis-acting elements, and responses to abiotic stress.

OsCYBDOMG1 positively regulates salt tolerance, plant growth, and grain yield by affecting ascorbate biosynthesis and redox state. Soil salinity is a major abiotic stress affecting rice growth and productivity. Many genes involved in the salt stress response have been identified, but the precise mechanisms underlying salt tolerance remain unclear.

Salt stress impairs nutrient metabolism in plant cells, leading to growth and yield penalties. However, the mechanism by which plants alter their nutrient metabolism processes in response to salt stress remains elusive. In this study, we identified and characterized the rice () () mutant, which displayed improved salt tolerance and grain yield.

Potassium (K) is an essential element for growth and development in both animals and plants, while high levels of environmental sodium (Na) represent a threat to most plants. The uptake of K from high-saline environments is an essential mechanism to maintain intracellular K/Na homeostasis, which can help reduce toxicity caused by Na accumulation, thereby improving the salt tolerance of plants. However, the mechanisms and regulation of K-uptake during salt stress remain poorly understood.

ATP-binding cassette (ABC) transporters participate in disease resistance by transporting JAs or antimicrobial secondary metabolites in dicotyledons. Here, we functionally characterized a JAs-inducible rice gene (OsPDR1) that encodes a member of the pleiotropic drug resistance (PDR) subfamily of ABC transporters.
