Description
Technical field
The invention belongs to the reference gene technical field of stably express in insect body in molecular biology, relate to reference gene screening method and the application of white backed planthopper different tissues position stably express particularly.
Background technology
White backed planthopper White-backed planthopper (Sogatella furcifera (Horv á th)), belongs to Arthropoda, Insecta, Hemiptera, Delphacidae, 3 etap of experience all one's life, comprise ovum phase, nymph and adult stage, adult has habit of migrating.White backed planthopper is widely distributed in China, and comprise south China, Central China, North China, northeast and southwestern rice district, rice district, northwest can reach the ground such as the Miquan of Xinjiang Autonomous Region has it to distribute.Paddy rice is white backed planthopper Suitable Host, and white backed planthopper not only can sting water suction rice phloem sap, can also propagate multiple virus disease, cause heavy losses to Rice Production.
White backed planthopper completes a life cycle to be needed, through ovum, nymph, adult three kinds of worm states, to belong to paurometaboly insect.There are for 3 ~ 4 generations in white backed planthopper 1 year, male imago comparatively female adult worm is sprouted wings early, a female adult worm mating in all one's life 1 time, and male imago can mating 3 ~ 4 times, and the position that female worm lays eggs concentrates on rice strain base portion.White backed planthopper also exists the polymorphism of form and behavior, namely the type that migrates (with long wing for representative) and residence type (with brachypterism type for representative), the differentiation of temperature Whitebacked Planthopper wing plays an important role, but generally white backed planthopper brachypterism type male worm seldom sees.In recent years, real-time fluorescence quantitative PCR (qRT-PCR) technology is quick with it, sensitive, accurate, repeatability is high, can be quantitative, applied widely etc. feature advantage, be widely used in gene expression analysis.Use relative quantitation method time need a reference gene that expression amount is constant in experimental group and control group as testing goal gene under given conditions expression level change object of reference, be used for the experimental data of both normalization method, reference gene is here reference gene.A reference gene can continual and steady expression be its applicable basic premise under specific experimental conditions.Desirable reference gene should meet the following conditions: there is not pseudogene, to avoid the amplification of genomic dna; Height or moderate are expressed; Stably express is in dissimilar biological cells and tissues; Expression level is similar to target gene; Be not subject to the impact of any endogenous or extrinsic factor.Conventional reference gene is all maintain the necessary gene of normal cell activities, as Actin, 18S, GAPDH, Tublin etc., but do not have a kind of reference gene mrna expression level to be unalterable at all conditions, some reference genes are under certain specified conditions, and its expression may change.Therefore, under studying different envrionment conditionss, the intragentic expression of a certain organism, the selection of reference gene is most important.In recent years, along with going deep into of insect functional gene research, some functional gene is widely different at the expression amount at different tissues position, studies the reason that this species diversity is formed, has great significance for illustrating of its function.The invention provides the method for screening white backed planthopper different tissues position stably express reference gene, and verified that the most stable reference gene is RPL9, for the research of following white backed planthopper functional gene is provided fundamental basis.
