Abstract
Background
Bromus japonicus Thunb. is a hazardous weed in wheat fields in China. One B. japonicus population, HB-1, which was collected in Hebei Province, survived field rate flucarbazone-sodium exposure.
Method
To investigate the mechanism of flucarbazone-sodium resistance in the HB-1 population, the herbicide target als gene was isolated, and the in vitro ALS activity was tested. HPLC‒MS/MS was applied to detect flucarbazone-sodium absorption and residue level. Furthermore, RNA-seq and qRT‒PCR were applied to detect genes related to flucarbazone-sodium metabolism or flucarbazone-sodium and its metabolite transport.
Result
The results indicated that in resistant population there were no mutations in the als gene sequences or differences in the IC50 of ALS compared with the sensitive population. In addition, als gene relative copy number and expression also showed no difference. However, significantly increased herbicide metabolism was found in the HB-1 population. In the end, four cytochrome P450 genes (C71D55b, C71A1, C71D55, T5H), three glutathione S-transferase genes (GSTZ, GSTU6b, GSTFB), and three ABC transporter genes (ABCC3, ABCF1, ABCG11) were selected and identified as potentially playing a role in flucarbazone-sodium resistance.
期刊介绍:
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
