Genetic diversity of SIRE-1 retroelements in annual and perrenial glycine species revealed using SSAP
journal contribution
posted on 2023-06-08, 10:34 authored by Catherine Chesnay, Amar Kumar, Stephen R PearceSequence Specific Amplification Polymorphisms (SSAP) were used to measure the distribution and structure of SIRE-1 retroelement populations in annual and perennial Glycine species. For SSAP analysis, primers corresponding to a region immediately upstream of the 3' LTR of the soybean retroelement SIRE-1 were chosen. Analysis reveals that SIRE-1 is present throughtout the Glycine genus and shows that the annual species have similar SIRE-1 populations whilst the perennial species have much more distinct and diverse populations. The high number of species-specific subgroups suggest that SIRE-1 has been active and evolving independently in each species during the course of Glycine evolution.

This publication uses the insertional polymorphism of one of the very few putative plant retroviruses (SIRE-1) to assess germplasm diversity in the commercially important Glycine genus. The data demonstrates that SIRE-1 is ancient and widespread which overturns the conventional view that SIRE-1 is a recent acquisition to the soybean genome.Full text available
