Аннотация
Ca2+ is an essential nutrient for plants and animals which plays an important role in plant signal transduction. Although the function and regulation of mechanism of Ca2+ in alleviating various biotic and abiotic stresses in plants have been studied deeply, the molecular mechanism to adapt high Ca2+ stress is still unclear in cotton. In this study, 103 cotton accessions were germinated under 200 mM CaCl2 stress, and two extremely Ca2+-resistant (Zhong 9807, R) and Ca2+-sensitive (CRI 50, S) genotypes were selected from 103 cotton accessions. The two accessions were then germinated for 5 days in 0 mM CaCl2 and 200 mM CaCl2 respectively, after which they were sampled for transcriptome sequencing. Morphological and physiological analyses suggested that PLR2 specifically expressed in R may enhance the ability of cotton to scavenge ROS by promoting the synthesis of SDG. In conclusion, this study proposed the adaptation mechanisms to response to the high Ca2+ stress in cotton which can contribute to improve the stress resistance of cotton.
