Comprehensive analysis of the NAC transcription factor gene family in Kandelia obovata reveals potential members related to chilling tolerance.

ABSTRACT:

Background

Kandelia obovata is an important mangrove species extensively distributed in Eastern Asia that is susceptible to low-temperature stress. NAC (NAM, ATAF1/2 and CUC2) domain proteins are transcription factors (TFs) that play various roles in plant growth and development and in the plant response to environmental stresses. Nevertheless, genome-wide analyses of K. obovata NAC genes (KoNACs) and their responses to chilling stress have rarely been studied.

Methods

The KoNAC gene family was identified and characterized using bioinformatic analysis, the subcellular location of some NAC proteins was confirmed using confocal microscopy analysis, and the KoNACs that responded to chilling stress were screened using RNA-seq and qRT-PCR analys
