Overexpression of GhMPK3 from Cotton Enhances Cold, Drought, and Salt Stress in Arabidopsis

Cotton production is hampered by a variety of abiotic stresses that wreak havoc on the growth and development plants, resulting in significant financial losses. According to reports, cotton areas have declined around world as result ongoing stress. Therefore, plant breeding programs are concentrating stress-tolerant varieties. Mitogen-activated protein kinase (MAPK) cascades involved growth, stress responses, hormonal signaling pathway. In this research, three (cold, drought, salt) were analyzed GhMPK3 transformed Arabidopsis plants. The transgenic plant’s gene expression morphologic analysis studied under cold, salt Physiological parameters such relative leaf water content, excised loss, chlorophyll ion leakage showed overexpressed plants possess more stable content conditions compared with WT Furthermore, had greater antioxidant activities weaker oxidant activities. Silencing inhibited its tolerance drought Our research findings strongly suggest can be regarded an essential for
