EMERGING BASIC AND APPLIED ADVANCES FOR RESEARCH ON ACQUIRED TOLERANCES OF PLANTS EXPOSED TO TEMPERATURE EXTREMES

Temperature stress is an assured reality for all horticultural crops, as nearly every plant experiences some form of temperature stress during its life cycle.
To cope with temperature extremes beyond the range of an organism’s optimum for growth, stress responses and survival strategies have evolved to varying degrees in an organism-specific fashion.
Irrespective of the type of temperature stress, response and tolerance mechanisms are the products of many genes.
The quantitative nature of temperature stress tolerance traits has implications in the complexity of molecular and cellular processes involved, and also for the efforts to improve the stress tolerance of plants using molecular biology approaches.
This article will outline recent advances in technology that are helping to advance our overall understanding of acquired tolerance mechanisms, and briefly discuss applications that offer the prospect of enhancing crop stress tolerance.
