Summary: A novel light intensity-dependent lesion mimic mutant with enhanced disease resistance was characterized physiologically, biochemically, and genetically, with the causative gene fine mapped to a 1.28 Mbp interval containing 17 high-confidence genes. The mutant exhibited a lesion phenotype with altered chloroplast structure, decreased chlorophyll content, increased reactive oxygen species, and enhanced resistance to stripe rust and powdery mildew, suggesting a novel single semi-dominant nuclear gene control. Fine mapping suggested the target gene Lm5 was located in a 1.28 Mbp interval containing 17 high-confidence candidate genes.

Summary: This study identified three quantitative trait loci (QTLs) related to Tiller angle (TA) in wheat, with QTa.sau-2B-769 being the major QTL on chromosome arm 2BL. A linked Kompetitive Allele-Specific Polymerase chain reaction (KASP) marker was developed to validate this locus in multiple populations. The results showed that QTa.sau-2B-769 increased TA by up to 24.9%. Significant positive correlations were found between TA and flag leaf angle (FLANG). Furthermore, the expression of QTa.sau-2B-769 was independent of vernalization and the candidate gene TraesCS2B01G583800 was identified.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
