摘要： The present disclosure provides polynucleotides and related polypeptides which are used to modify ethylene sensitivity in plants. Ethylene insensitive transgenic maize plants produce higher grain yields in water deficient and low nitrogen environments than non-transgenic plants. Through controlled expression of the transgene in desired tissues and organs, or specific plant developmental stages, the ethylene perception and signal transduction is altered to create transgenic plants which yield better under abiotic stress.
