Details:       “Genetic dissection of drought tolerance in wheat”
	       
	       ABSTRACT
	       Tolerance to drought is a quantitative trait, with a
	       complex phenotype, often confounded by plant phenology.
	       Breeding for drought tolerance is further complicated
	       since several types of abiotic stress, such as high
	       temperatures, high irradiance and nutrient toxicities or
	       deficiencies can challenge crop plants simultaneously.
	       There are additional problems in investigating the
	       genomics of drought tolerance in wheat: most pathways
	       and candidates genes are unknown and progress in
	       genomics and gene cloning had been slowed due to the
	       size (16,000 Mb) and the complexity of the genome
	       (hexaploid). A research program for increasing drought
	       tolerance of wheat should tackle the problem in a
	       multi-disciplinary approach, considering interaction
	       between multiple stresses and plant phenology, and
	       integrating the physiological dissection of drought
	       tolerance traits and the genetic and genomics tools,
	       such as quantitative trait loci (QTL), microarrays and
	       transgenic crops. The strategy developed at the ACPFG
	       target a specific environment and select appropriate
	       germplasms adapted to the chosen environment based on
	       extensive definition of the morpho-physiological and
	       molecular mechanisms of tolerance of the parents.
	       Traditional genetics and recent omics tools are used to
	       create structured populations and develop models for QTL
	       analysis and positional cloning.
