Rice grain shape regulation protein HOS59 as well as coding gene and application thereof

Abstract

The invention discloses a rice grain shape regulation gene protein HOS59 as well as a coding gene and application thereof. One technical scheme protected by the invention is application of protein or a substance for regulating and controlling the activity or content of the protein in regulating and controlling or increasing the grain length of plant grains and / or the grain epidermal cell length. Experiments prove that after the expression quantity and / or activity of the HOS59 protein in the rice are / is reduced, the grain length and the grain epidermis cells of the obtained transgenic rice are obviously longer than those of wild rice Nipponbare; and in the HOS59 transgenic overexpression strain, the grain length and the grain epidermis cells are obviously shortened compared with those of the wild type. The research on the HOS59 is helpful for increasing new gene resources in the aspect of grain shape regulation and control of the plants; in actual production, rice grain traits can be regulated and controlled by regulating and controlling the HOS59, so that a new rice high-yield variety is cultivated.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to rice grain shape regulation protein HOS59 and its coding gene and application. Background technique [0002] Rice is one of the most important food crops in the world, once feeding more than half of the world's population. Rice is facing the real problem of increasing demand and decreasing arable land, which puts forward great requirements for increasing the yield of crops. In addition, according to forecasts, the world's major food crops rice, wheat and maize are expected to suffer substantial production losses due to climate change. This also puts forward high requirements for the environmental adaptability of rice. Under this requirement, the excavation of rice high-yield genes is of great significance for realizing the goal of "high yield, high quality, high efficiency, ecology, and safety" in rice production. [0003] Rice grain shape is an important indicator of rice yield a...

Problems solved by technology

However, rice grain type is a complex regulatory process. If we want to comprehensively and systematically explain the regulatory mechanism of rice grain type, we still need to dig and identify more functional genes.
