Lathion plus metsulfuron-methyl treatment (M + Just after BLAST analysis of your ALS amino acid of R. STING Inhibitor Compound kamoji (GenBank accession MZ368697) 12X).in the NCBI database, we found that the ALS amino acid of R. kamoji has 99 Monoamine Transporter Formulation identity to wheat (Triticum aestivum) and 73 identity to Arabidopsis thaliana (Figure 3). Utilizing BioEdit to evaluate the amino acid sequence of 4 R. kamoji populations, A. thaliana, and T. aestivum, the results showed that some amino acids of R. kamoji are inconsistent with T. aestivum, but none of them were related for the reported resistance-associated substitutions. These final results indicated that the tolerance to ACCase inhibitors in R. kamoji populations might be caused by non-target-site tolerance mechanisms.Plants 2021, ten, x FOR PEER REVIEWPlants 2021, 10,4 ofFresh weight ( of manage)HBJZ HBJZ+Malathion ZJHZ ZJHZ+Malathion0 10Metsulfuron-methyl (g ai ha)Figure 2.
