Phylogenetic analysis of C, M, N, and U genomes and their relationships with Triticum and other related genomes as revealed by LMW-GS genes at Glu-3 loci.
Genome. 2011 Apr; 54(4):273-84.G

Abstract

Phylogenetic relationships between the C, U, N, and M genomes of Aegilops species and the genomes of common wheat and other related species were investigated by using three types of low-molecular-weight glutenin subunit (LMW-GS) genes at Glu-3 loci. A total of 20 LMW-GS genes from Aegilops and Triticum species were isolated, including 11 LMW-m type and 9 LMW-i type genes. Particularly, four LMW-m type and three LMW-i type subunits encoded by the genes on the C, N, and U genomes possessed an extra cysteine residue at conserved positions, which could provide useful information for understanding phylogenetic relationships among Aegilops and Triticum genomes. Phylogenetic trees constructed by using either LMW-i or the combination of LMW-m and LMW-s, as well as analysis of all the three types of LMW-GS genes together, demonstrated that the C and U genomes were closely related to the A genome, whereas the N and M genomes were closely related to the D genome. Our results support previous findings that the A genome was derived from Triticum uratu, the B genome was from Aegilops speltoides, and the D genome was from Aegilops tauschii. In addition, phylogenetic relationships among different genomes analysed in this study support the concept that Aegilops is not monophyletic.
