A new mechanism of Arabidopsis NF-Ycs regulating photomorphogenesis revealed

Under the guidance of researcher Hou Xingliang, assistant researcher Zhang Chunyu of the Agricultural and Biotechnology Research Center of the South China Botanical Garden of the Chinese Academy of Sciences discovered that light signals promote the sedimentation of H2A.

.

Through a series of experimental analysis of protein interactions, the researchers found that NF-YCs can interact light-dependently with ARP6, a key component of the SWR1 complex
.

This study revealed that NF-YCs-ARP6, a new transcriptional regulatory module, mediates the deposition of H2A.

It is worth mentioning that in recent years, Hou Xingliang’s research team has made a series of progress in the study of the function of NF-YCs, revealing that NF-YCs play a role in the growth and development of Arabidopsis plants such as flowering, seed germination, and hypocotyl elongation.
