Isolated polynucleotide, Construction of nucleic acid, host cells, Transgenic plant of Brassica, soybean and Corn Seed and Progeny of the same, method for modifying the content of saturated fatty acids in the host Cell, a method for Increasing the expression of beta ketoacyl ACP synthetase

摘要

Polynucleotide Sequence identical in sequence to the sequence identified as SEQ ID NS1 Sequence that are 50% to 99% identical to the same, complementary sequences, sequences that hybridize under stringent conditions of hybridization with the aforementioned sequences and constructs that C Omprenden this sequence.Such polynucleotide sequences that can be obtained from natural sources, such as cyanobacteria, as artificial encode polypeptides, in particular the beta ketoacyl ACP synthase (KAS), which plays an indispensable role in the synthesis of fatty acids.Method to modify and reduce the content of saturated fatty acids in a host cell of a transgenic plant of soybean, corn, or Brassica. Host cells and progenies of such plants, Seeds and Oils with reduced saturated fatty acids obtained thereof are also described.
