Rice tiller control gene MOC1 and its application

Abstract

The present invention utilizes rice single tiller mutant Mono culm 1(moc1) to clone and identify the gene capable of controlling rice tiller, and its name is MOC1. The transgenic function complementary assay shows that MOCI is the gene for controlling rice tiller, and the amino acid sequence comparison analysis shows that said gene belongs to the GRAS transcription factor family. The gene can be used for regulating tiller character of rice.

Description

technical field The invention belongs to the field of plant genetic engineering. Specifically, the present invention relates to a MOC1 (MoNo CULML) gene cloned by a map-based cloning technique, and the gene is identified by a transgenic function complementation experiment; The carrier of the homologous gene and involves the use of the gene or its functional analogue to regulate the tillering or side branch generation ability of the plant so as to regulate the population structure of the plant and improve the yield, quality and nutrient light energy utilization efficiency of crops. Background technique Tillering is an important morphological characteristic of most grasses. The stems of gramineous crops have buds at each node. The buds can develop into branches, and the bases of the branches form adventitious roots. Such branches are tillers. The morphological characteristics of the tillers are basically the same as those of the main stem, and the tillers can be separated fr...

Problems solved by technology

It will be a more economical and effective way to realize the regulation of rice tiller number through biotechnology; so far, there is only one report on the research on genes controlling the occurrence of side shoots in plants (13)
