Genes Controlling Plant Root Growth And Development For Stress Tolerance And Method Of Their Use

摘要

Microarrays are employed to analyze soybean transcriptome under water stress conditions in different regions of the root at vegetative stage. Drought responsive genes and transcription factors are identified which may be used for enhancing drought tolerance in soybean or other plants through genetic/metabolic engineering. This disclosure pertains to nucleic acid molecules isolated from soybean and maize that encode polypeptides that may be important for drought tolerance. The disclosure also relates to methods of using these genes from soybean in transgenic plants to confer the desired agronomic traits, and to use such genes or regulatory elements thereof to assist germplasm enhancement by molecular breeding or to identify other factors or chemicals that may enhance a plant's capability to grow under drought conditions.
