Método para modular a resposta de uma planta ao ácido abscísico (aba), método para reduzir os efeitos negativos do estresse sobre o desenvolvimento de sementes de plantas, construção de dna e polinucleotídeo isolado.

摘要

Compositions and methods for modulating abscisic acid (ABA) perception and signal transduction in developing seed are provided. The methods and compositions find use in increasing yield in plants, particularly under abiotic stress. Compositions comprise genetic constructs known to affect ABA sensitivity, particularly ABA biosynthetic mutants and fragments and variants thereof.
