De novo identification and targeted sequencing of SSRs efficiently fingerprints Sorghum bicolor sub-population identity.

Recent plant breeding studies of several species have demonstrated the utility of combining molecular assessments of genetic distance into trait-linked SNP genotyping during the development of parent lines to maximize yield gains due to heterosis. SSRs (Short Sequence Repeats) are the molecular marker of choice to determine genetic diversity, but the methods historically used to sequence them have been burdensome. The ability to analyze SSRs in a higher-throughput manner independent of laboratory conditions would increase their utility in molecular ecology, germplasm curation, and plant breeding programs worldwide.

Physiological and molecular analysis of glyphosate resistance in non-rapid response Ambrosia trifida from Wisconsin.

Background: We previously identified a glyphosate-resistant A. trifida phenotype from Wisconsin USA that showed a non-rapid response to glyphosate. The mechanism of glyphosate resistance in this phenotype has yet to be elucidated.
