Description

A kind of plant type of rice growth and development correlative coding gene and its application
Technical field
The present invention relates to gene engineering technology field, in particular to a kind of plant type of rice growth and development correlative coding gene and It is applied.
Background technique
Rice is one of most important cereal crops of the mankind, accounts for about 50% by the population of staple food of rice in the world.Asia Area increases the demand of rice year by year, since rapid economic development, population pressure increase, industrial land increases severely, arable land face Product is reduced, and Rice Production faces huge pressure.Therefore high yield potential that is constantly improve and excavating rice, is the master of scientists Want research direction.Plant type of rice and quality, yield have close relationship.Plant type of rice is in group's light posture, luminous energy, water Key effect is played on fertilizer, space utilization rate, output increased and quality-improving.Plant type depends primarily on plant type, blade profile, tiller number Several aspects such as mesh, tillering angle and fringe portion form.In recent years, become using molecular biology method cloning rice plant type gene The rice plant type gene of the hot spot of research, clone has important theory and practical guidance to rice dwarf breeding, plant type improvement Meaning.
The rice plant type gene for having cloned clear function at present reaches 21, sd1, d2 including No. 1 chromosome of rice, The genes such as d10, d18, d61, gid2, gid1 control semi-dwarf mutant and short bar character, and the gid2 gene of No. 2 chromosome controls short bar Character, No. 3 chromosome d14, brd1, fc1, OsDWARF4 gene control plant types are formed, and the d11 gene of No. 4 chromosome controls water The short bar of the more tillers of rice, the eui1 control internode beneath spike elongation of No. 5 chromosome, No. 6 chromosomes d3 and d35 control short bar character, No. 7 dyes Colour solid d6 gene, No. 8 chromosome SPY, IPA1 genes, the brd2 gene of No. 10 chromosome control the formation of plant type of rice.So And the genetic entities comprehensive agronomy trait expression for the control plant type of rice character excavated and identified at present is poor, current plant type is educated The main problem of kind is that applicable plant type gene is very little, and how breakthrough bottleneck applies new plant type gene to seem particularly critical. Be richly stored with gene in oryza officinalis, excavates the beneficial gene of oryza officinalis.It is excavated from wild rice and identifies strain Type new resources deeply probe into the molecular mechanism of regulation plant type, it will help rice breeding man is MOLECULE DESIGN in breeding process Breeding improvement rice plant and leaf shape provides theoretical foundation, finally realizes high-efficient breeding.
