摘要

Isolated nucleic acid, a plant or plant cell, method for increasing the capacity of the drainage, accelerate the remobilizau00e7u00e3o and / or senescence and drying of grain in a plant, a method for increasing the tolerance to drought in the absence of a penalty of productivity under conditions without dry.The tape of expression and method to reduce the expression of zmme293 or the activity of a plant zmme293 in the present invention refers to methods for modular plants with the use of optimized constructs regulatory descendant of zmme293.Are also presented sequences of nucleotide constructs, vectors, plant cells and modified, as well as transgenic plants that have increased productivity of seed and / or tolerance to abiotic stress enhanced biomass, such as drought or high density of plant efficiency of U. Tilizau00e7u00e3o nitrogen enhanced, greater number of spike and / or reduction in time of senescence.
