Genome-wide identification and expression analyses of the homeobox transcription factor family during ovule development in seedless and seeded grapes.

ABSTRACT: Seedless grapes are of considerable importance for the raisin and table grape industries. Previous transcriptome analyses of seed development in grape revealed that genes encoding homeobox transcription factors were differentially regulated in seedless compared with seeded grape during seed development. In the present study, we identified a total of 73 homeobox-like genes in the grapevine genome and analyzed the genomic content and expression profiles of these genes. Based on domain architecture and phylogenetic analyses grape homeobox genes can be classified into eleven subfamilies. An analysis of the exon-intron structures and conserved motifs provided further insight into the evolutionary relationships between these genes. Evaluation of synteny indicated that segmental and tandem duplic
