Entified (Hou et al., 2016), and InsP3 generates InsP6 by means of a series of enzymatic reactions. InsP6 could be the major storage form of phosphate in plants as well as the second messenger of plants. It might regulate Ca2+ release, hormone receptor TIR1, gene expression, etc. (Munnik and Vermeer, 2010). When melatonin is sensed by receptor CAND2/PMTR1, it triggers the dissociation of G type G, which activates the downstream H2 O2 and Ca2+ signaling transduction cascade, top to the phenotype of stomatal closure (Wei et al., 2018). Intracellular Ca2+ increases, thereby initiating stimulationspecific downstream signal transduction. That is dependent upon the array of calcium sensors. The calcium sensors are categorized into CaMs (calmodulins), CMLs (CaM-like proteins), CDPKs (Ca2+ dependent protein kinases), and CBLs (calcineurin B-like proteins) (Srivastava et al., 2013). These sensor proteins can directly perform their functions or interact with corresponding decoding elements. The application of melatonin and Ca2+ inhibits ROS generating enzymes, like NADPH oxidase inside the plasma membrane and GOX in peroxisomes, respectively (Siddiqui et al., 2020). Within this study, we discovered that melatonin melanin plays a crucial part in enhancing the salt tolerance of cotton, laying a certain theoretical foundation for improving the salt tolerance of cotton.CONCLUSIONAs an antioxidant defense technique and signaling molecule, melatonin plays an indispensable function inside the response of plants to abiotic anxiety, and has fantastic prospective in enhancing crop response to abiotic tension. The content material of endogenous melatonin in cotton may impact its salt tolerance. In this study, we made use of S1PR4 Source exogenous application of melatonin to increase the salt tolerance of cotton, and inhibiting the content material of endogenous melatonin decreased the cotton salt tolerance, indicating that melatonin and cotton salt tolerance are closely associated. PLK2 Formulation RNA-seq technology was utilised to discover the mechanism of melatonin regulating the salt stress of cotton in the molecular level.
