EXPRESSION CASSETTES AND METHODS FOR INCREASING PLANT YIELD

摘要

An expression cassette and a method for improving plant yield are provided. The cassette comprises a mesophyll-specific promoter, a pyrophosphatase gene and a terminator, which are operably-linked. The method for improving plant yield comprises transforming the mesophyll-specific expression cassette of pyrophosphatase into plants, and screening for plants capable of expressing pyrophosphatase, then obtaining the plants with improved yields. The transgenic plant cell and whole plant produced by the method are also provided.
