Genome-Wide Identification and Expression Pattern Analysis of Dirigent Members in the Genus Oryza.

ABSTRACT: Dirigent (DIR) members have been shown to play essential roles in plant growth, development and adaptation to environmental changes. However, to date, there has been no systematic analysis of the DIR members in the genus Oryza. Here, 420 genes were identified from nine rice species to have the conserved DIR domain. Importantly, the cultivated rice species Oryza sativa has more DIR family members than the wild rice species. DIR proteins in rice could be classified into six subfamilies based on phylogeny analysis. Gene duplication event analysis suggests that whole genome/segmental duplication and tandem duplication are the primary drivers for DIR genes' evolution in Oryza, while tandem duplication is the main mechanism of gene family expansion in the DIR-b/d and
