USDA Researchers Develop New Tool to Identify Key Soybean Genes
February 19, 2014| |
Researchers from the US Department of Agriculture (USDA) have developed a new tool to search for soybean genes that will make soybean plants more productive and better able to resist pests and diseases.
The tool, developed by Agricultural Research Service (ARS) scientists Perry Cregan, Qijian Song and Charles Quigley, allows scientists to collect genetic information in three days, a process that previously took weeks to gather. It is called the SoySNP50K iSelect SNP BeadChip, a glass chip about 3 inches long with an etched surface that holds thousands of DNA markers. The researchers used the chip to profile 96 wild and 96 cultivated soybean varieties and identified regions of the genome that played a key role in the plant's domestication.
