The molecular biology of 1 bee considers to make progress
As the bee complete gene measures what foreword works to finish, apian EST plans to also had been begun, be become by preparation CDNA chip. These achievement make clear times of form of the gene after the bee considers to had been entered. At the same time already the article turns through drawing lessons from referenced other animal the report with successful gene discussed a bee to turn the feasibility of gene technology system, undertook an analysis to the applied foreground of this technology. But the research field that the molecular biology of concerned bee researchs to basically still be centered in genetic mark.
The characteristic that 1.1 of all kinds heredity label
Say commonly, label main component labels for configuration hereditarily, cytology mark and element label 3 kinds. Method of these 3 kinds of mark has actor drawback each. Because its have typical configuration feature,configuration labels, allow legibility and observation quite, facilitate consequently the impact that determines they and other character. In the meantime, because equipment is simple, analytic cost is low, interlink as species group build start sexual sign, configuration number also is having main effect in the fixed position that in other the element labels, but its defect is with photograph of other and harmful or adverse character chain has undesirable much effect sex, make analyse and be used be restricted. In addition, use configuration mark to undertake quantitative gene fixed position returns pair of experiment environments to have higher demand. Cytology mark overcame configuration mark to suffer the defect that the environment affects easily, but the labor power with the preparative need much expenditure of stuff of this kind of number, at the same time the bee suffers chromosome structure and amount mutation capacity poorer and obtain relevant mark data hard.
With classic form mark and cytology mark photograph are compared, sex of DNA member much state is being moved plant and microbial in be widespread presence, have on same gene seat more wait for a gene, restrict on applied limits consequently less, not quite sufficient to configuration mark and cytology mark development bee especially important; Sex of molecular much state is harmless to apian itself, rare also to important economy character sub effect, have very big choice room; The element is much at the same time voice sex from individual, organization, the different level such as organ and cell determines, and do not suffer environmental effect, in the bee each period of development can undertake genetic analysis, this offerred huge to go to the lavatory to research work; Of seat of gene of sex of molecular much state wait for a gene to be in all dominance mark, the genotype of almost all likelihood can be distinguished in separate group, or it is dominance genotype at least, can use in all cross combination consequently. The advantage that the element labels place is had locates to gene especially the gene fixed position of quantitative character showed good prospect.
