Scientists share keys to drought tolerance Some of the world's leading crop researchers met in Adelaide recently to discuss breeding strategies for increasing plants' water-use efficiency By Gio Braidotti With global grain stocks at their lowest levels in decades and water stress accounting for a glaring proportion of global shortfalls, the 2007 Genomics Symposium in Adelaide allowed some of the world's best drought-tolerance pre-breeders to put their heads together on new ways to test, select and dissect traits that can maintain yields under drought... Overall, genomics is currently playing a more peripheral role in the work of conventional pre-breeders, with scientists attempting to dissect the genetic basis of drought tolerance and map traits to discrete chromosomal subregions (called QTLs or quantitative trait loci)... The number of GM field-trials is on the rise...
