Complete set reagent and method for increasing plant seed yield

Abstract

The invention discloses a complete set reagent and method for increasing the plant seed yield. The complete set reagent for increasing the plant seed yield consists of a promoter named STK and a protein named bzr1-1D; STK is a DNA molecule represented by the 1-30933 site of the sequence 1 in the Sequence Listing; bzr1-1D is a protein with the amino acid sequence as the sequence 2. Experiments showthat the use of the complete set reagent can promote the reproductive growth of plants and increase the plant seed yield without affecting the vegetative growth of the plants, especially the leaf area, that is, the reproductive growth of plants is promoted without changing the leaf size to ensure the nutrient supply of the plants and without increasing the occupied area, and the seed yield is increased.

Description

technical field [0001] The invention relates to a set of reagents and a method for increasing the yield of plant seeds in the field of biotechnology. Background technique [0002] Traditional research shows that the vegetative growth and reproductive growth of plants are inseparable, and the growth of various plant organs is interdependent and mutually promoting, which is the correlation of plant growth. The correlation of plant growth is mainly reflected in three aspects: root and aerial part, main stem and side branch, vegetative growth and reproductive growth. Vegetative growth is the basis and premise of reproductive growth. Under normal conditions, vigorous vegetative growth has large leaf area and many photosynthetic products, so that fruits and seeds can develop well; otherwise, poor vegetative growth will lead to short and thin plants and incomplete development of flower organs. , fruit growth retardation, small fruit, few seeds, low yield. By improving the vegetat...

AI Technical Summary

Problems solved by technology

By improving the vegetative growth of plants, the number of seeds of a single plant and the yield of plants can be increased, but in terms of unit area, as the vegetative growth conditions of plants become better, the vegetative organs will increase accordingly, and the occupied area will increase, resulting in The number of plants per unit area decreases, so the yield per unit area of ​​plants does not increase with the increase in yield per plant, and there may be a decline in yield per unit area
