Zinc Finger-Homeodomain Genes: Evolution, Functional Differentiation, and Expression Profiling Under Flowering-Related Treatments and Abiotic Stresses in Plants.

ABSTRACT: Zinc finger-homeodomain (ZHD) proteins constitute a plant-specific transcription factor family that play important roles in plant growth, development, and stress responses. In this study, we investigated a total of 10, 17, and 31 ZHD gene members in the peach, Arabidopsis, and apple genome, respectively. The phylogenetic tree divided the identified ZHD genes into 4 subfamilies based on their domain organization, gene structure, and motif distribution with minor variations. The ZHD gene family members were unevenly distributed throughout in apple, peach, and Arabidopsis genomes. Segmental duplication was observed for 14 pairs of genes in apple. Transcript analysis found that ZHD genes mostly expressed in various tissues, particularly in leaves and flowers. Moreover, the
