Summary: Global climate changes have increased water stress in arid and semi-arid regions, reducing plant growth and yield. This study aimed to evaluate the mitigating effect of salicylic acid and methionine on cowpea cultivars under water restriction conditions. The results showed that water stress decreased leaf area and fresh mass, and increased total soluble sugars and catalase activity. BRS Pajeu showed higher tolerance to water stress compared to BRS Novaera. The application of salicylic acid and methionine had a stronger effect on BRS Novaera, stimulating its tolerance mechanism to water stress.

Summary: The desiccation tolerance of plants requires defense mechanisms that protect macromolecules, biological structures, and metabolism. This study found that both leaves and roots of Haberlea rhodopensis have high levels of non-enzymatic antioxidants and antioxidative enzyme activity during desiccation, indicating the importance of protective compounds and antioxidative defense mechanisms in both tissues.

Summary: Drought is a significant environmental factor affecting the yield and quality of apples grown in arid and semi-arid regions. Nuclear factor Ys (NF-Ys) play a crucial role in regulating plant growth, development, and stress responses. The identification and functional characterization of NF-Y genes in apples, particularly the upregulation of MsNF-YB21 in response to drought, offer promising insights for enhancing apple drought tolerance through biotechnological approaches.

Summary: This study found that exogenous brassinolide (BL) can enhance the alkaline stress resistance of M. hupehensis seedlings. The main mechanisms include regulating rhizosphere pH, promoting Ca2+ and Mg2+ absorption, decreasing rhizosphere pH, alleviating ion toxicity, balancing osmotic stress, and reducing oxidative damage.
