Survey and summary study of Lr10 gene sequences in different genomes of bread wheat by using genome-informatics

Wheat (Triticum aestivum L.) is one of the four major cereals in the entire world. As one of the most important agricultural crops, wheat is a staple food crop for a large portion of the world’s population. Nearly, 80-90 percent of the wheat genome sequence has been includes repeated sequence and 70 percent with mobile elements is known. Nowadays, more than 50 leaf rust resistance genes in wheat genome and related species have been identified. The Lr10 gene hasbeen originated from wheat. This gene is a single-copy gene that located on chromosome 1A. One of the fields of bioinformatics is molecular analysis that includes alignment the sequences, search on the databases, motif and domain identification, drawing of the evolutionary relationships and comparative genomics. In our study, the results indicate that there is a reasonable classification based on Lr10 gene between of investigated wheat genomes and the evolution has been changed in the sequence of investigated genes. Based on investigated genes, the studied genomes were classified into three classes. The first class includes T.dicoccoides and T.urartu, the second class contains T.aestivum and durum wheat and the last class contains T. monococcum wheat.
