Genome-Wide Identification of the Zinc Finger-Homeodomain (ZF-HD) Gene Family and Their Response to Cold Stress in Rosa chinensis.

ABSTRACT:

Background

The zinc finger-homeodomain (ZF-HD) transcription factor family exerts pivotal regulatory functions in plant development and stress responses, yet a systematic genome-wide survey is lacking for Rosa chinensis.

Methods

In this study, we performed a comprehensive genome-wide identification and analysis of RcZF-HD genes in R. chinensis using bioinformatics approaches. Nine RcZF-HD loci were mined from the rose genome and comprehensively profiled for physicochemical parameters, phylogenetic affiliations, chromosomal positions, exon-intron architectures, conserved motifs, and spatiotemporal expression landscapes.

Results

The results showed that RcZF-HD genes were unevenly distributed across four chromosomes (Chr2, Chr4, Chr6, a
