FRUCTOSE POLYMER SYNTHESIS IN MONOCOT PLASTIDS

摘要

This invention concerns methods for synthesis and accumulation of fructo- oligosaccharides in seeds of monocot plants by selective expression of a fructosyltransferase gene sequence. Selective expression includes coordinati on of timing, tissue specific expression and especially subcellular location. Successful transformants utilize sucrose to synthesize and accumulate fructo - oligosaccharides in the plastid of the cell, in established crops, without loss of co-products or concern for yield loss due to degradation during maturation, harvest or storage of the plant. Enhanced fructo-oligosaccharide production will benefit the fructose sweetener industry and add value to gra in used for feed.
