Mechanism of metamifop resistance in var. from Jiangsu, China.

var. is one of the most competitive and problematic grass weeds in China. Metamifop is an aryloxyphenoxypropionate (APP) herbicide that inhibits the activity of acetyl-CoA carboxylase (ACCase) of sensitive weeds.

Proteomic and Transcriptomic Analyses Provide Novel Insights into the Crucial Roles of Host-Induced Carbohydrate Metabolism Enzymes in Xanthomonas oryzae pv. oryzae Virulence and Rice-Xoo Interaction.

Background: Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial leaf blight, a devastating rice disease. The Xoo-rice interaction, wherein wide ranging host- and pathogen-derived proteins and genes wage molecular arms race, is a research hotspot.

Increasing tolerance to bispyribac-sodium is able to allow glutathione homeostasis to recover in indica rice compared with japonica rice.

The high activity and broad weed spectrum of BS has made it widely used in China. However, accidental crop injuries, particularly occurring in Jiangsu, Hunan, Hubei and Heilongjiang provinces in recent years, have resulted in limiting the application of BS in China. In this study, glutathione homeostasis was measured in the contrasting sensitivity of indica and japonica rice cultivar after bispyribac-sodium (BS) treatment.

The role of cytochrome P450 monooxygenase in the different responses to fenoxaprop-P-ethyl in annual bluegrass (Poa annua L.) and short awned foxtail (Alopecurus aequalis Sobol.).

Herbicide resistance or tolerance in weeds mediated by cytochrome P450 monooxygenase is a considerable problem. However, cytochrome P450 mediated resistance or tolerance in weeds was less studied. Thus, in this work, the role of the cytochrome P450 monooxygenase in the different responses of Poa annua and Alopecurus aequalis to fenoxaprop-P-ethyl was studied.
