Structure and distribution of WD40 genes in sunflower (Helianthus annuus L.) chromosomes

The WD40 protein family plays an important role in response to abiotic stresses. This research led to the identification of 266 WD40 genes in sunflower. CDS sequences and genomic sequences were extracted from the helia gene database. The position of the intron and exons each of WD40 genes was then determined using the gsdsdatabase. In additions, the physical location of genes, including the length of the gene, the starting point, and the end of the point was determined and so mapped on 17 sunflower chromosome using Mapchart software. The results of the analysis showed that chromosome 4 had the highest number of WD40 genes and chromosome 7 had the lowest number of WD40 genes.
