Gossypium spp. pigment glands are a good model for studying plant secretory cavity structures. GoPGF (GOSSYPIUM PIGMENT GLAND FORMATION) is a well-characterized master transcription factor that controls gland formation in cotton; however, little is known about its transcriptional regulation.

The pigment glands, unique to cotton and its relatives, serve as a defense structure against pests and pathogens. However, the molecular mechanism underlying gland formation and the specific role of pigment glands in cotton's pest defense are still not well understood.

Here, we showed that GoPGF, a key gene regulating gland formation, was expressed in gland cells and roots. The chromatin immunoprecipitation sequencing (ChIP-seq) analysis demonstrated that GoPGF targets GhJUB1 to regulate gland morphogenesis.
