TL;DR
Pyroxsulam helps wheat tolerate bixlozone herbicide by reducing damage and boosting detoxification processes.
Contribution
This study reveals how pyroxsulam enhances wheat's tolerance to bixlozone through activation of detoxification pathways.
Findings
Pyroxsulam co-treatment reduces bixlozone-induced chlorosis and restores wheat tiller number and yield.
Pyroxsulam mitigates bixlozone's negative effects on chlorophyll, carotenoids, and photosystem II function.
Transcriptome analysis shows pyroxsulam activates GSTs and ABC transporter genes involved in detoxification.
Abstract
Bixlozone has significant potential as a pre-emergence and early post-emergence herbicide in wheat production across China. However, its safety when applied to wheat is poor, frequently causing phytotoxicity. This study confirmed the capacity of pyroxsulam to mitigate bixlozone-induced injury without compromising weed control efficacy and examined the underlying processes. Wheat exposed to bixlozone alone developed pronounced chlorosis and significant reductions in tiller formation, ultimately lowering the grain yield. In contrast, co-treatment with pyroxsulam substantially relieved chlorosis and restored both the tiller number and yield performance. Bixlozone reduced chlorophyll and carotenoid levels, impairing the function of photosystem II (PSII), which was mitigated by pyroxsulam application. Transcriptome profiling showed that pyroxsulam strongly activated detoxification-related…
