Soybean Response to Plant Growth Regulator Herbicides: Field Evaluation and Expression Analysis of Candidate Auxin -Responsive Genes
A lack of diagnostic tools specific to PGR herbicides often result in difficulty and confusion when responding to reported cases of soybean symptoms resembling PGR herbicide injury. PGR herbicides overstimulate the auxin hormonal pathway and induce gene expression. Identifying genes specifically …
