LAS1基因在皂苷高产型海参选育中的应用
Abstract:
本发明的目的是提供一种LAS1基因在皂苷高产型海参选育中的应用，通过高效检测LAS1基因关键催化位点，以实现皂苷高产型海参的选育。本发明首先提供仿刺参LAS1基因，该基因编码的氨基酸序列为SEQ ID NO:1，其一种编码基因的核苷酸序列为SEQ ID NO:2，上述刺参LAS1基因中的10个皂苷合成的关键催化位点，包含有LAS1蛋白氨基酸序列的第4位(L)、第5位(R)、87位(P)、104位(L)、214位(L)、249位(L)、434位(W)、441位(H)和531位(S)、648位(S)；本发明所提供的10个皂苷合成的关键催化位点可用在皂苷高产型刺参的选育中。
Abstract(English):

The invention aims to provide an application of LAS1 gene in breeding of sea cucumbers with high yield of saponins. The sea cucumbers with high yield of saponins are bred by efficiently detecting keycatalytic sites of the LAS1 gene. Apostichopus japonicus LAS1 gene is provided firstly, an amino acid sequence encoded by the gene is shown in SEQ ID NO: 1, and one of encoding genes has a nucleotidesequence shown in SEQ ID NO: 2. Ten key catalytic sites for synthesis of the saponins in the apostichopus japonicus LAS1 gene comprise 4th (L), 5th (R), 87th (P), 104th (L), 214th (L), 249th (L), 434th (W), 441st (H), 531st (S) and 648th (S) of the protein amino acid sequence of LAS1. The ten key catalytic sites for synthesis of the saponins can be applied to breeding of the sea cucumbers with high yield of saponins.
