Disease is a constant issue for growers; but new regulations are likely to curb the use of chemical treatments. US researchers have made genome maps of more than 1,000 vine samples. Writing in Proceedings of the National Academy of Sciences (PNAS), they say this type of data plots the way to disease-resistant grape varieties. – read more on BBC
