Abstract

The invention discloses a plant starch synthesis associated protein IbAATP and encoding genes and an application thereof. The plant starch synthesis associated protein IbAATP provided by the invention is (1), (2) or (3): (1) a protein of which an amino acid sequence is shown in a sequence 2 of a sequence table; (2) a fused protein obtained in a way that a label is connected to the N end or / and C end of the protein shown in the sequence 2 of the sequence table; (3) a plant starch synthesis associated protein obtained by the substitution and / or deletion and / or adding of the protein shown in (1) or (2) through one or several amino acid residues. Experiments show that the plant starch synthesis associated protein IbAATP and the encoding genes provided by the invention can increase the total content of plant starch and / or change the quality of the starch.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular relates to a plant starch synthesis-related protein IbAATP and its coding gene and application. Background technique

[0002] Sweet potato (Ipomoea batatas (L.) Lam.) is an important food, feed and industrial raw material crop, and as a new energy plant in today's world, its status is particularly important. my country is the world's largest sweet potato producer, with an annual planting area of ​​3.482 million hectares, accounting for 43.0% of the world's total planting area, and its annual output accounts for 68.6% of the world's total output. my country is currently in a period of rapid development, and the demand for energy continues to increase, so finding new alternative energy sources will be a long-term strategic work. As a root crop, sweet potato is rich in starch, and starch is one of the important raw materials for industrial ethanol production. Therefore, through in-dep...
