Coix lacryma-jobi gliadin alpha-coixin gene, its coding gene and application

Abstract

The invention discloses a prolamin alpha-coixin gene in the Coix lacryma-jobi L. and coded protein and application, which contains one of the following nucleotide sequences: (1)DNA sequence as SEQ NO 1-18; (2)DNA sequence to code the same function as protein with consanguinity over 95% in the SEQ NO 1-18. The invention can modify the quality of seed protein of coix lacryma-jobi, which reaches the goal to cultivate superior maize (high lysine maize).

Description

technical field

[0001] The invention relates to a prolamin α-coixin gene in Coix lacryma-jobi L., its encoded protein and its application. Background technique

[0002] Coix (Coix) belongs to the Poaceae Coix genus, which is closely related to corn and belongs to the Maydeae family. Job's tears has a long history of cultivation in my country, and has long been used as a traditional Chinese medicinal material rather than a food crop. The planting area of ​​Job's tears in my country is the largest among medicinal crops, accounting for about one-fifth to one-fourth of the total planting area of ​​medicinal materials. It is also the most widely distributed, and it is cultivated almost all over the country. In recent years, it has been found that the coix seed contains coixenolide with a very unique structure, which has the effect of preventing and treating cancer, which also makes the study of coix arouse people's attention.

[0003] Coix seed not only contains coixenolide, bu...
