New plant acyltransferases specific fatty acids long chain polyunsaturated

Method for the production of polyunsaturated fatty acids in a plant oily fruits characterized porqueel method includes the following steps: a) incorporating at least one nucleic acid sequence in the plant with secuenciarepresentada in SEQ ID NO: 1 or SEQ ID NO : 20, which encodes a polypeptide with a lysophosphatidic acid s odium acyltransferase activity; b) incorporating at least one nucleic acid sequence in the plant, which is derived from lasecuencia encoding present in SEQ ID NO: 4 or SEQ ID NO: 20, as a result of geneticodegenerado code, or c) incorporation of a sequence nucleic acid in the plant, which encodes polypeptides witha homology of at least 80% amino acid level with SEQ ID NO: 2 or SEQ ID NO: 21 and exhibeuna activity lysophosphatidic acid acyltransferase, and d) growing and harvesting organism.
