Overview

Genome analysis uncovers the traits of Ascorbate Peroxidase genes in oat, suggesting roles in chloroplast development.

Key Points

  • The research aims to identify and analyze the characteristics of the APX gene family in oat.
  • Identified 27 APX gene members in oat (Avena sativa L.)
  • Conducted phylogenetic analysis to categorize AsAPXs
  • Analyzed promoter regions for cis-elements related to light and phytohormones
  • Performed qRT-PCR to examine gene expression response to light
  • APX genes were unevenly distributed across 15 chromosomes
  • Amino acid sequences ranged from 112 to 510 residues
  • Molecular weights varied between 11.83 to 55.45 kDa
  • Phylogenetic analysis categorized AsAPXs into five branches
  • Identified 41 cis-element recognition sites mainly involved in light response
