Physiological requirements for wheat ideotypes in response to drought threat

Understanding the theoretical aspects of crops drought resistance is fundamental for maintaining the present rate of yield growth which is the key factor in the prospect of increasing world population. Achievements in plant physiology and biochemistry uncovered many metabolic pathways and defined indicators of plant resistance to environmental stresses. Genetic research contributed to discoveries of gene regulation in stress tolerance. As the result of fast development of genetics, phenomics became a hold-up of further functional research. In this paper, problems related to phenotype requirements for crops cultivation in drought threatened areas will be presented against the background of achievements in metabolomics and genomics. Theoretical speculations of Blum on crop water use efficiency will be examined against the results of Sirius simulation with HadCM3 climate projections and against practical phenological requirements for present crops.
