MEANS AND METHODS FOR THE REDUCTION OF PHOTORESPIRATION IN CROPS

摘要

The present invention relates to the field of plant molecular biology and concerns methods for enhancing the abiotic stress tolerance in plants by modulating the expression of the glyoxylate reductase gene. The present invention also provides chimeric constructs useful in the methods in the invention. In addition, the invention provides transgenic plants having an enhanced abiotic stress resistance, in particular an enhanced tolerance to high light conditions and an improved CO2 fixation.

主权项

1. A chimeric gene comprising the following elements:
i) A plant-expressible promoter, ii) A DNA region which when transcribed yields a glyoxylate reductase inhibitory RNA molecule; and optionally iii) A 3′ end region involved in transcription termination and polyadenylation.
