Genotype-by-Sequencing (GBS) is reduced representation of a genome, which utilizes restriction enzymes (e.g. ApeKI) and NextGen sequencing to identify biallelic markers and presence/absence markers. In this post, my attempt is to consisely present the GBS SNP calling process in 7 steps using the TASSEL GBSv2 pipeline. Pleae note:, Buckler et... [Read More]

Building genetic maps can be challenging and sometimes quite stressful, especially, when dealing with thousands or even millions of markers. In this post, I am hoping to help anyone who would like to get started to build a decent genetic map in an open software Lep-MAP3 , and finally, the... [Read More]

I was interviewed by the Wine Enthusiast Magazine on their special edition on “Wine and Tech”, where i had an opportunity to represent our VitisGen2 project and talk about how computers are being used to “hack” Grapes! [Read More]

Abstract: Teosinte (Zea mays ssp. parviglumis) is the wild ancestor of modern maize (Zea mays ssp. mays). Teosinte contains greater genetic diversity compared to maize inbreds and landraces, but its use is limited by insufficient genetic resources to evaluate its value. A population of teosinte near isogenic lines (teosinte NILs)... [Read More]

Abtract The mature seeds of soybean (Glycine max L. Merr) are a valuable source of high-quality edible lipids and protein. Despite dramatic breeding gains over the past 80 years, soybean oil continues to be oxidatively unstable, due to a high proportion of polyunsaturated triacylglycerols. Until recently, the majority of soybean... [Read More]
