Özet
Growth-regulating factor (GRF) genes may play important roles for regulating growth and development in different plant tissues and organs. Here we report the first genome-wide analysis of the GRF gene family in Brachypodium. We performed in silico comparative analysis of GRF genes, including their structure, duplication in the genome, conserved motifs, and phylogenetic relationship. At the end of the study, 10 BdGRF genes were identified. The highest number of GRF genes was identified on chromosome 1 with 5 members, whereas the least number of genes (only 1 member) was found on chromosomes 2, 4, and 5. Of those, a single segmental duplication was observed in the Brachypodium genome. Average exon and intron numbers were determined as 3 and 4, respectively. Motif analysis showed that WRC and QLQ residues were consistent in all GRF protein sequences. Gene Ontology terms showed that 10 BdGRF proteins grouped in the same biological function, biological process, and cellular component groups. In addition, we compared the new BdGRF proteins with the other monocot and dicot GRF proteins sequences. Phylogenetic analysis revealed that GRF proteins of monocot and dicot species were clustered together in a joined tree; in particular, the monocot species (Brachypodium, maize, and rice) were grouped into the same cluster with high bootstrap values. We assume that the results of this study will provide molecular insights about GRF proteins in grass species.
