Plant responses to environmental stress.
Considerable progress is being made in identifying genes that are important for tolerance to abiotic stress and in defining stress-responsive gene promoters and signal-transduction pathways. Although genetically engineered crop plants with greater resistance to environmental stress have not yet been produced, research is at a turning point where correlative changes can now be tested for effectiveness in conferring stress tolerance.
