PWOs repress gene transcription by regulating chromatin structures in Arabidopsis.

PWWP-DOMAIN INTERACTOR OF POLYCOMBS (PWO) family proteins play a vital role in regulating plant development. However, the molecular mechanisms of how PWOs regulate chromatin structure is elusive. Our data show that the PWO1 binding sites are enriched with positive modifications but exclusive with H3K27me3.

Progress in studying heteromorphic leaves in : leaf morphology, anatomical structure, development regulation and their ecological adaptation to arid environments.

Oliv. is a tree that is strongly resistant to drought and salt stress, which is primarily distributed in arid and semiarid lands. The leaves of the species exhibit a special feature that causes them to be designated as heterophylly.
