SPAIN – DROUGHT RESISTANT PLANTS DEVELOPED
Extreme drought is one of the effects of climate change that is already occurring. This year, the decrease in rainfall and the abnormally hot temperatures in northern and eastern Europe have caused large losses in cereals and potato crops and in other horticultural species. Experts have long warned that to ensure food security, it is becoming necessary to use plant varieties that are productive in drought conditions. Now, a team led by the researcher at the Center for Research in Agricultural Genomics (CRAG) Ana Caño-Delgado has obtained plants with increased drought resistance by modifying the signaling of plant steroid hormones known as brassinosteroids. The study, published in the journal Nature Communications, is the first to find a strategy to increase hydric stress resistance without affecting overall plant growth.
