摘要

Plant transformation vector for suppressing MIPS gene expression and method for culturing low phytate soybean provides a plant transformation vector and method for transforming soybean plants. The vector is design to suppress or enhance gene of interest in plants. The plant transformation vector comprises a plant active promoter, a terminator, a plant selection marker and a bacterial selection marker. The present invention also provides a method of transformation for reducing phytate in soybean comprises growing a soybean plant comprising MlPS"intron hairpin expression cassette operably linked to a promoter {vicilin) that drives tissue specific expression in plants. The expression of this novel RNAi hairpin cassette for silencing MIPS gene disclosed here in confers advantageous nutritional properties i.e. reduced phytate content with increased inorganic phosphorous and mineral bioavailability, and leads to valuable and useful soybean products.
