Summary: The gene GhWRKY46, encoding WRKY transcription factor protein, was found to potentially be associated with drought and salt pressure. Overexpression of GhWRKY46 in Arabidopsis enhanced tolerance to salt and drought, improved survival rates, chlorophyll contents, and biomasses. GhWRKY46 also increased the expression of stress-related genes in the transgenic Arabidopsis, indicating its positive regulation of responses to drought and salt stresses.

Summary: Polyploidy provides an opportunity for species diversification and evolutionary innovation, especially under stressful conditions. This study investigates the regulatory mechanisms underlying salt resistance diversity in Gossypium species. The results show that salt responsiveness varies across different cotton species, with differences in gene expression patterns and functional implications. Allopolyploid cottons have acquired a wide range of stress response flexibility relative to their diploid ancestors, which is likely mediated by duplicated genes and regulatory factors.

Summary: The study revealed that salt stress negatively impacted plant growth, water consumption, leaf water relations, and leaf gas exchange rates, while increasing water use efficiency. Changes in plant hormone concentrations, chlorophyll content, nitrogen concentration, and biomass partitioning were also observed under salt stress. Additionally, alterations in leaf gas exchange response to salt stress were mediated by changes in hydraulic and chemical properties, ultimately leading to sustained cotton yield with less water consumption.

Summary: The GhGRL28 gene plays an important role in salt tolerance in cotton plants, and its silencing leads to poor growth and increased oxidative stress under salt stress conditions. These results suggest that GhGRL28 actively regulates redox reactions induced by stress and is crucial for maintaining the growth and development of cotton plants under stress conditions.

Summary: In this study, the upregulation of GhMYB102 gene during early stages of drought stress in upland cotton was identified through analysis of drought transcriptomic data. GhMYB102, which encodes a conserved MYB transcription factor, is closely related to AtMYB102 and is mainly expressed in roots. Silencing of GhMYB102 resulted in decreased drought resistance in plants. Furthermore, GhMYB102 was found to directly bind promoter regions of GhNCED1 and GhZAT10 and regulate their expression, suggesting its positive role in drought tolerance by participating in ABA biosynthesis or regulating the expression of drought-responsive genes.

Summary: Drought stress affects cotton production, and understanding the plant characteristics that contribute to drought tolerance is important. This study evaluated different genotypes of cotton under control and drought stress conditions, and identified tolerant genotypes based on their responses to drought stress. Root growth traits, as well as the accumulation of photosynthates and proline, were identified as key indicators of drought resistance. Tolerant genotypes of G. hirsutum were found to be more tolerant than obsolete genotypes of G. barbadense and G. arboreum. These identified genotypes can be used in cotton breeding programs.

Summary: This study investigated the combined effect of elevated temperature and drought on cotton fiber development. The results showed that the combined stress had a more negative impact on fiber biomass and cellulose synthesis. The effects of temperature and drought on sucrose synthesis and degradation in fibers were different, and they had an antagonistic effect when combined. The combined stress also led to increased callose accumulation.

Summary: GhDRP1 acts as a negative regulator in response to drought stress by modulating ABA signaling pathway and flavonoid biosynthesis pathway, affecting stomata movement, water loss, ROS scavenging enzymes, and proline accumulation in cotton. GhDRP1 overexpression transgenic cotton and Arabidopsis exhibited reduced drought tolerance, while GhDRP1-silenced cotton showed enhanced drought tolerance.

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.
