Professor Wang Wenming’s team has made new progress in the research on the coordination mechanism between rice yield and resistance
By: Date: 2021-11-10 Categories: foodtechnology Tags: ,

It is generally accepted that yield and resistance are two key antagonistic factors in crop production. Improving resistance often comes at the cost of reducing yield. In view of this bottleneck problem, recently, a research result of Professor Wang Wenming’s team in the State Key Laboratory of Southwest crop gene resources exploration and utilization of Sichuan Agricultural University revealed the mechanism of rice mir1871b-osmfap1 module in synergistic regulation of rice blast resistance and yield per plant, finding a new breakthrough for cultivating rice varieties with high resistance and high yield.

Professor Wu Yidong’s team deciphers a new mechanism of beet armyworm P450-mediated abamectin resistance
By: Date: 2021-07-17 Categories: foodtechnology Tags: ,

Recently, the team of Professor Wu Yidong of Nanjing Agricultural University published the latest research results in the important international academic journal PLoS Genetics. The study constructed the first high-quality chromosome-level reference genome of Spodoptera exigua, and revealed that Spodoptera exigua cytochrome P450 oxidase has a single amino acid mutation through a variety of methods such as gene map cloning, gene editing, and in vitro functional expression. A new mechanism for the development of resistance to mycotoxins.

Focus! What are the changes in the resistance of vegetable pests?
By: Date: 2021-03-02 Categories: foodtechnology Tags: ,

In accordance with the requirements of the”Regulations on the Prevention and Control of Crop Diseases and Insect Pests”, in 2020, the National Agricultural Technology Center will organize 100 pesticide resistance monitoring points nationwide to monitor rice planthoppers, rice stem borers, wheat aphids, wheat head blight, whitefly, and rice (wheat) fields. Weeds and other 24 major diseases, pests and weeds were monitored for drug resistance. After expert consultations were organized, the”2020 National Agricultural Pest Resistance Monitoring Report” was formed. This article only extracts the relevant content of”the resistance status of vegetable pests”.
