| Abstract/Contents: | "Poa annua is an allopolyploid weed of turfgrass systems that has evolved resistance to almost every herbicide mode of action. Allopolyploidy is the product of whole genome duplication following the hybridization of two distinct diploid species, resulting in homologous gene pairs, or homeologs from separate progenitor species. Research suggests that subgenome mutation bias exists in polyploid species. In this study we focused on specific single nucleotide polymorphisms (SNPs) EPSPS (Pro106) and ALS (Trp574) that result in herbicide resistance, and Ka/Ks ratio analysis of transcriptome assemblies to determine if a subgenome bias exists in the progenitor genomes of P. annua, P. supina and P. infirma. Through the utilization of amplicon sequencing (AmpSeq), we were able to determine that there is a bias for mutations to occur in the paternal Poa supina subgenome of Poa annua over the Poa infirma subgenome. Because P. supina is the non-dominant genome, more mutations should accumulate, resulting in a mutation biased subgenome. This claim was strengthened based on a Ka/Ks ratio test. More regions should be studied to strengthen our claim, however based on this data we can reasonably assume that P. annua does have a subgenome bias towards its progenitor Poa supina." |
