摘要： Main conclusionGoSCL was involved in the regulation of pigment glands in the stem of cotton.AbstractIn this study, we identified a transcription factor named GoSCL, which was involved in the regulation of pigment gland in the stem. Silencing of GoSCL decreased not only the number of pigment glands but also the accumulation of gossypol in the stem of the treated plants. GoSCL showed a temporal and spatial pattern of expression in various organs of glanded and glandless cotton plants and demonstrated the inducible expression under exogenous ethylene treatment. The relationship between GoSCL and genes involved in gland formation and gossypol synthesis was also discussed. These results advance our understanding of the molecular basis of cotton gland formation and gossypol synthesis and accelerate the molecular breeding of cotton with low-gossypol seeds and high-gossypol plants.
