IDENTIFICATION OF GENES CONTROLLING ROOT SYSTEM ARCHITECTURE TRAITS IMPORTANT FOR P ACQUISITION AND AL TOLERANCE FOR CROP ON ACID SOILS
Project Number: 1907-21000-036-12
Start Date: May 15, 2011
End Date: May 14, 2013
The objectives of the research are to identify genes that are involved in crop plant tolerance to low phosphorous (phosphorous efficiency) and toxic levels of Al (Al tolerance) in acid soils, with a focus on the regulation and signaling between P efficiency and Al toxicity.
The approaches will involve the use of digital imaging and computer-based reconstruction of root system architecture (RSA) in 3D to phenotype soybean and sorghum mapping populations for QTL controlling different components of RSA. The research will set the stage for future research identifying genes important for tolerance to low P and Al tolerance for crop production on acid soils.
