METHOD FOR THE PRODUCTION OF TRANSGENIC PLANTS HAVING HIGH STARCH AND BIOMASS CONTENT AND YIELD

摘要

The invention relates to a method for the production of transgenic plants having high starch and biomass content and yield. SSs in plants (including SSIV) and glycogen synthase in bacteria catalyse the transfer of the glucoside portion of the ADP-glucose molecule (the activated glucose donor) to a preexisting a(1-4) glucan. However, unlike with other SSs, SSIV is capable of adding glucose units to maltotrioses. Furthermore, unlike with other "soluble" SSs, SSIV is bound to the starch granule. The invention contains the first description of the method for obtaining plants having high levels and yields of starch and biomass as a consequence of the expression of genes coding for SSIV.
