AtINO80 represses photomorphogenesis by modulating nucleosome density and H2A.Z incorporation in light-related genes (ChIP-seq)

Photomorphogenesis is a critical developmental process bridging light-regulated transcriptional reprogramming with morphological changes in organisms. Strikingly, the chromatin-based transcriptional control of photomorphogenesis remains poorly understood. Here, we show that both light-induced genes and dark-induced genes were affected in the atino80 mutant. Genome-wide occupancy of the H2A.Z histone variant and levels of histone H3 were reduced in atino80. examination of 2 different histone modifications in 2 samples with 2 replicates. Samples without antibody were used as input control.
