Lathion plus metsulfuron-methyl treatment (M + Following BLAST evaluation from the ALS amino acid of R. kamoji (GenBank accession MZ368697) 12X).within the NCBI database, we discovered that the ALS amino acid of R. kamoji has 99 identity to wheat (Triticum aestivum) and 73 identity to Arabidopsis thaliana (Figure 3). Applying 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 have been connected to the reported resistance-associated substitutions. These final results indicated that the tolerance to ACCase inhibitors in R. kamoji populations may be caused by non-target-site tolerance mechanisms.Plants 2021, 10, x FOR PEER REVIEWPlants 2021, 10,4 ofFresh JNK2 manufacturer weight ( of handle)HBJZ HBJZ+Malathion ZJHZ ZJHZ+Malathion0 10Metsulfuron-methyl (g ai ha)Figure 2.
