Abstract

Metribuzin resistance in wheat is crucial for successful weed control. Near-isogenic lines (NILs) targeting a major metribuzin resistance locus explaining 69% of the phenotypic variance were developed and studied by mRNA sequencing and proteomic analyses, revealing nitrate excretion transporter, aspartyl protease, glycine-rich protein, WD repeats, AB hydrolase_1 and PsbP as major candidate genes/proteins associated with metribuzin resistance. A number of molecular markers associated with the candidate genes responsible for metribuzin resistance were identified, which can be validated and applied to marker-assisted selection (MAS) in wheat breeding while identified genes/proteins can help to understand genetic mechanism of metribuzin resistance in wheat.
