Vegetable glutelin transportation storage related protein OsVps9a as well as coding gene and application thereof

Abstract

The invention discloses a vegetable glutelin transportation storage related protein OsVps9a as well as a coding gene and application thereof. The protein is selected from (a) or (b) as follows: (a) protein formed by an amino acid sequence shown in SEQ ID NO.1; and (b) protein for replacing and / or deleting and / or adding one or more amino acid residues in the amino acid sequence shown in SEQ ID NO.1, related to the vegetable glutelin transportation storage and derived from the SEQ ID NO.1. Vegetables with normal mature glutelin content can be cultivated by introducing the coding gene of the protein into vegetables with lowered mature glutelin content. The protein and the coding gene can be applied in the genetic improvement of vegetables.

Description

technical field

[0001] The invention belongs to the field of genetic engineering and relates to a plant gluten protein transport and storage related protein OsVps9a, its coding gene and application. Background technique

[0002] Higher plants accumulate a large amount of storage substances in their seeds during the reproductive period, and plant seeds have thus become the main source of food for humans. Rice (Oryza sativa L.) is one of the most important food crops in the world, and more than 50% of the world's population takes rice as the main ration. Rice contains a large amount of storage protein, which is the second largest substance in rice after starch. Therefore, in-depth research on storage protein is of great significance for improving the eating quality and nutritional quality of rice.

[0003] The storage proteins in rice seeds account for about 8-10% of the grain dry weight, of which glutenin accounts for 60-80%, and prolamin accounts for 18-20%. Among them, g...
