Chinese medicine herbs could defeat devastating cotton virus, study suggests
- Scientists find some chemicals can kill the cotton leaf curl Multan virus and others can boost cotton plants’ immunity to it
- It is feared the virus could wreak havoc in China’s Xinjiang region, which produces most of the country’s cotton
Chinese scientists have found chemicals in medicinal herbs that could tame a destructive plant virus threatening the cotton industry in its western Xinjiang region.
Some small-molecule chemicals in herbs commonly used in Chinese medicine can effectively suppress cotton leaf curl Multan virus, according to ongoing research led by Professor Ye Jian at the Institute of Microbiology in Beijing.
By targeting WRKY20, a gene in the virus’ DNA, the chemicals could disrupt the viral infection and transmission, Ye’s team found.
Some early findings from their research were published last month in the journal Science Advances.
The leaf curl virus – a species of Begomovirus, the largest genus of plant viruses – poses a significant threat to the world’s cotton plantations, causing leaf curling, stunted growth and lower yields of cotton fibre. It costs the cotton industry in the Indian subcontinent about US$1 billion a year, according to a press release about the study from the Chinese Academy of Sciences.
