AI Article Synopsis
- Researchers found that HUB1 influences circadian clock genes in Arabidopsis, impacting how these genes are expressed.
- The hub1-1 mutant showed lower levels of histone H2B monoubiquitination at gene regions, leading to changes in circadian gene expression.
- The study indicates that variations in histone modification via monoubiquitination can affect overall plant fitness in different HUB1 lines.
Article Abstract
Recently, we have identified circadian clock genes as targets of Histone Monoubiquitination1 (HUB1) in Arabidopsis from a transcriptome comparison between the hub1-1 mutant and HUB1 overexpression lines. HUB1 affected the amplitudes of the circadian clock gene expression profiles in the hub1-1 mutant that coincided with reduced monoubiquitination of histone H2B at their coding regions. Here we showed that parameters for plant fitness are altered in HUB1 mutant and overexpression lines, suggesting that the histone H2B monoubiquitination status affects plant fitness.
