AI Technical Summary
Technical Problem
The unclear mechanism of starch grain development makes it difficult to improve rice quality, especially since there is a lack of effective means to genetically regulate the quantity and morphology of starch grains.
Method used
The rice starch grain development-related gene OsESG2 was cloned and expressed, and then introduced into the rice genome through a recombinant vector to repair OsESG2 defects and restore normal starch grain development.
Benefits of technology
It normalized starch granule development, improved the eating quality and industrial application value of rice, and restored the quantity and morphology of starch granules.

Abstract
This invention discloses a starch grain development-related gene, OsESG2, and its applications. The nucleotide sequence of the gene OsESG2 provided by this invention is shown in SEQ ID NO.1 or SEQ ID NO.2. Introducing the encoding gene OsESG2 into plants with abnormal starch grain development can cultivate plants with normal starch grain development. The gene and its encoded protein can be applied to crop genetic improvement.
