Identification and characterization of histone modification gene family reveal their critical responses to flower induction in apple.

ABSTRACT:

Background

Histone methylation and acetylation regulate biological processes in plants through various histone modifications (HMs) gene families. However, knowledge of HMs genes is limited in horticultural deciduous trees, including apple (Malus domestica).

Results

Here, a comprehensive study of identifying and investigating HMs genes was performed using the recently published apple genome. In total, 198 MdHMs were identified, including 71 histone methyltransferases, 44 histone demethylases, 57 histone acetylases, and 26 histone deacetylases. Detailed analysis of the MdHMs, including chromosomes locations, gene structures, protein motif and protein-protein interactions were performed, and their orthologous genes were also predicted against nine plant species. Meanwhile, a sy
