USE OF ALDH7 FOR IMPROVED STRESS TOLERANCE

摘要

The present invention relates to the field of plant molecular biology, more particularly to the regulation of genes that increase drought tolerance and yield. Provided herein are methods finding use in agriculture for increasing drought tolerance in dicot and monocot plants. Methods comprise modulating the aldehyde profile of a plant. Compositions comprise plants comprising modulated aldehyde profiles. A polynucleotide encoding an ALDH7 polypeptide, operably linked to a promoter that drives expression in a plant, may be introduced into a plant. Also provided are transformed plants, plant tissues, plant cells, and seeds thereof.

主权项

1. A method of altering the aldehyde profile of a maize plant under drought stress, the method comprising increasing or decreasing the level of one or more aldehydes in said plant compared to a control plant, wherein the maize plant comprises an eluent profile of aldehydes having a retention time between 4.15 minutes and 25.00 minutes using liquid chromatography-mass spectrometry performed according to standard settings.
