Summary: Phytopathogenic strains of Fusarium oxysporum cause destructive vascular wilt disease in economically important crops, and the use of resistant cultivars is an effective strategy for disease management. Our study showed that disruption of the BAM3 gene increased resistance to F. oxysporum f. sp. raphani, as the bam3 mutant exhibited reduced susceptibility to the pathogen. Additionally, cell wall pectin modification through methylesterification is important for bam3 defense responses against F. oxysporum.

Summary: Cellulosic ethanol is an alternative to increase bioethanol production worldwide. The degradation of sugarcane straw in the field showed significant changes in the composition of carbohydrates and lignin, with rapid degradation of non-structural carbohydrates and slower degradation of cellulose. The data suggest that for soil mineralization, sugarcane straw should stay in the field for over a year, while for bioenergy purposes, it should be utilized within 3 months.

Summary: Methyl jasmonate and salicylic acid have significant effects on the growth, quality, and antioxidant activity of Chinese chive. Specific concentrations of methyl jasmonate and salicylic acid can increase the levels of chlorophyll, phenols, flavonoids, vitamin C, and volatile components, as well as reduce the accumulation of nitrate. In addition, methyl jasmonate can increase the content of soluble sugar and protein, while salicylic acid can increase the dry and fresh weight of Chinese chive.

Summary: Recent studies show that preharvest treatments with salicylic acid (SA) and methyl jasmonate (MeJA) can mimic stress and enhance phytochemical compounds in different crops. This study investigated the effects of MeJA and SA treatments on the antioxidant properties, amino acid contents, and storage qualities of 'Kumato' tomatoes. The results suggest that MeJA and SA treatments can improve the storability and nutritional quality of tomatoes without compromising sensory qualities.

Summary: Paspalum dilatatum, a productive C4 grass, is widely distributed in temperate warm regions and known for its tolerance to frost and water stress. It has a higher forage quality than other C4 grasses. This species includes different forms, including tetraploid, sexual, and pentaploid apomictic forms. However, it is predominantly cultivated in an apomictic monoculture, which increases the risk of biotic and abiotic stresses affecting grass productivity. Aimed at improving agronomic traits, the development of reproducible and efficient regeneration and transformation protocols is crucial. This review discusses the current methods and limitations of regeneration and transformation in both apomictic and sexual cultivars of P. dilatatum, and explores the potential of genetic modification for creating improved forage varieties. The progress in this area positions P. dilatatum as a model species for molecular improvement of C4 perennial forage species.

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.

Summary: Plants have evolved a mechanism called 'stress memory' to survive in various environmental stresses. This study reveals the physiological, biochemical, and molecular mechanisms underlying drought stress memory formation in cotton, highlighting the role of histone modification H3K4me3 in regulating transcriptional memory. It also investigates the intergenerational inheritance of drought stress memory in cotton, providing theoretical guidance for cotton breeding.
