MIKC-Type MADS-Box Gene Family Discovery and Evolutionary Investigation in Rosaceae Plants

MADS-box is an important transcriptional regulatory element in plant growth. The MIKC-type genes play roles. However, the identification and evolutionary investigation of family members Rosaceae have been inadequate. Therefore, based on whole-genome data from Prunus dulcis, salicina, armeniaca, persica, mira, Amygdalus nana, we depicted evolution divergence patterns genes. In this study, found 222 six species. These were classified into five clades, only motif 1 was identified across all proteins, except PdMADS42 PmiMADS16. structural properties these significantly varied sequence lengths between species, despite high levels similarity exon numbers. to mostly limited through purifying selection processes. Remarkably divergent regions inside genes’ domains, where clade III displayed more conserved activities may retained original functions over process; I, other hand, undergone substantial functional limitations a specific role. findings provide groundwork for future research molecular processes gene family.
