Arabidopsis HOOKLESS1 Acts as a Histone Acetyltransferase to Promote Cotyledon Greening during Seedling De-etiolation (PRJCA033523)
The greening process in plants relies on a complex transcriptional network that fine-tunes the biosynthesis of chlorophyll and prevents premature development of chloroplast. In this study, we identified the Arabidopsis HLS1 as a key regulator of light-induced cotyledon greening. Our results demonstrated that HLS1 is essential for the proper expression of greening-related genes controlling chlorophyll biosynthesis and chloroplast development.
