Genome-Wide Identification and Characterization of wALOG Family Genes Involved in Branch Meristem Development of Branching Head Wheat.

ABSTRACT: The branched spike phenotype is an important supernumerary spikelet trait of Triticum turgidum L. associated with the production of significantly more grains per spike, thereby offering a higher potential yield. However, the genetic basis of branch meristem (BM) development remains to be fully elucidated in wheat. TAW1, an ALOG (Arabidopsis LSH1 and Oryza G1) family gene, has been shown to function as a unique regulator in promoting BM development in rice. In this study, we found that the development pattern of the BMs of the branched spike in wheat was similar to the indeterminate BMs of rice. Moreover, phylogenetic analysis classified the ALOG genes into 12 groups. This family of genes was found to have evolved independently in eudicots and monocots and was evolutionarily conserved betwe
