LHP1 promotes axillary bud dormancy by epigenetically repressing TIE1 in Arabidopsis.

Plant physiology - 2 Jul 2026

Schild Camila, Mammarella María Florencia, Mansilla Natanael, Maslein Delfina, Ariel Federico, Lucero Leandro

Abstract excerpt

Axillary bud dormancy is tightly regulated to control shoot branching through an intricate gene regulatory network (GRN). While epigenetic regulation of gene expression plays a key role in modulating GRNs underlying numerous developmental and physiological processes, its contribution to axillary bud dormancy remains largely unexplored. Here, we investigate the role of the plant polycomb repressive complex 1...
