Abstract:

The objective is to clarify the differences of dehydration tolerance of plant seeds and excavate key genes of relative rapid dehydration. We summarized the formation hypothesis, physiological basis and dehydration tolerance difference in the plant seed desiccation tolerance, analyzed the molecular mechanism of seed desiccation tolerance in genome-wide, transcriptome and proteome. At last, we pointed out that the genome-wide methods could be used to locate systematically the genetic diversity and related genes of different types of varieties in the world, and to excavate key genes for seed dehydration sensitivity.

Key words: plant seed, dehydration tolerance, physiology and biochemistry, influencing factors, molecular mechanism
