Identification of the Wheat (Triticum aestivum) IQD Gene Family and an Expression Analysis of Candidate Genes Associated with Seed Dormancy and Germination

ABSTRACT: The IQ67 Domain (IQD) gene family plays important roles in plant developmental processes and stress responses. Although IQDs have been characterized in model plants, little is known about their functions in wheat (Triticum aestivum), especially their roles in the regulation of seed dormancy and germination. Here, we identified 73 members of the IQD gene family from the wheat genome and phylogenetically separated them into six major groups. Gene structure and conserved domain analyses suggested that most members of each group had similar structures. A chromosome positional analysis showed that TaIQDs were unevenly located on 18 wheat chromosomes. A synteny analysis indicated that segmental duplications played significant roles in TaIQD expansion, and that
