520 |a The COMPASS-like complex, responsible for depositing H3K4 methylation, exhibits a conserved composition across yeast, plants, and animals, with functional analysis highlighting its crucial roles in plant development and stress response. In this study, we identified nine genes encoding four subunits of the COMPASS-like complex through homologous search. Phylogenetic analysis revealed the presence of two additional ASH2 genes in the sorghum genome, specifically expressed in endosperms, suggesting the formation of a unique COMPASS-like complex in sorghum endosperms. Y2H and BiFC protein-protein interaction tests demonstrated the interaction between SbRbBP5 and SbASH2A/B/C, while the association between other subunits appeared weak, possibly due to sequence variations in SbWDR5 or synergistic interactions among COMPASS-like complex subunits. The interaction between ATX1 and the C-Terminal Domain (CTD) of Pol II, reported in Arabidopsis, was not detected in sorghum. However, we made the novel discovery of transcriptional activation activity in RbBP5, which is conserved in sorghum, rice, and Arabidopsis, providing valuable insights into the mechanism by which the COMPASS-like complex regulates gene expression in plants
