Overview

Functional analysis reveals distinct roles for Dof genes in resistance to Phytophthora parasitica in Citrus, indicating involvement in hormone signaling.

Key Points

  • This research aims to characterize Dof transcription factors in Citrus clementina and analyze their role in disease resistance.
  • Identified 24 Dof genes in the Citrus clementina genome.
  • Conducted phylogenetic analysis to classify Dof proteins into clades.
  • Analyzed gene structure, conserved motifs, and promoter elements.
  • Performed expression profiling in response to phytohormones and stress.
  • Investigated the effects of CcDof4 and CcDof6 overexpression on resistance to Phytophthora parasitica.
  • Phylogenetic analysis revealed evolutionary conservation with Dof members from Arabidopsis.
  • CcDof genes show tissue-specific expression and response to phytohormones and stresses.
  • CcDof4 and CcDof6 overexpression enhanced resistance to P. parasitica.
  • Overexpression resulted in upregulation of SA pathway markers NPR1 and PR1.
