摘要:
The present invention relates to nucleotide sequences encoding polypeptides with cis-aconitic decarboxylase activity, the cells transformed with such nucleotide sequences, preferably fungal or plant cells, and to methods wherein such transformed cells are use for the production of itaconic acid.
摘要:
The present invention provides male-sterile plants. The plants have a recombinant polynucleotide integrated into their genome, essentially comprising an inhibitory gene, which, upon proper expression in the anthers of the plant, is capable of inhibiting expression of one or more genes encoding an enzyme involved in the synthesis of chalcone, or one of its precursors.
摘要:
A DNA fragment is disclosed having a nucleotide sequence SEQ ID NO. 1 as shown in FIG. 4A or a homologous sequence having a similarity of at least 70% encoding 1-sucrose:sucrose fructosyltransferase. Another DNA fragment that is disclosed is a DNA fragment having a nucleotide sequence SEQ ID NO. 3 as shown in FIG. 4B or a homologous sequence having a similarity of at least 70% encoding 1-fructan:fructan fructosyltransferase. This invention also discloses a recombinant DNA comprising one or more of said DNA fragments, or comprising said DNA fragment(s) in the inverted orientation. Transformed organisms showing a modified fructan profile can be produced using said fragments.
