Description

Brown paddy plant hopper NlAtg3 gene, coding albumen and its application
Technical field
The present invention relates to a kind of brown paddy plant hopper NlAtg3 gene, coding albumen and its applications.
Background technique
Brown paddy plant hopper (Nilaparvata lugensSt l) it is a kind of monophagy rice grub, mainly pass through feeding rice Phloem sap is caused harm rice.Currently, the emergence control to brown paddy plant hopper is mainly controlled by chemical pesticides, but chemical prevention is easy to lead The drug resistance of pest is caused to rise, on rice the problems such as harmful substance residual, pest resurgence and environmental pollution.In prevention and treatment brown paddy plant hopper Pesticide in, once played effective pesticide of better effects, such as Fipronil, imidacloprid, Buprofezin, cleaned out or Limitation uses, to find out its cause, such chemical pesticide mostly kills pest as target, still, due to brown paddy plant hopper using extensive high intensity The extremely complex equal practical reasons of population genetic diversity, wherein often have some individuals that can survive, high selection pressure Exercising result eventually results in population more adaptable and is formed.On the other hand, chemical pesticide is while killing off the insect pests, The non-target organism including natural enemy can be jeopardized, inevitably adversely affected to farmland ecosystem, cause to give birth to State prevention and treatment function cannot get due performance.Therefore, it screens and prevents and treats target with new brown paddy plant hopper is found, adjust current brown paddy plant hopper Control strategy has important practical significance.
CN107988244A discloses a kind of brown paddy plant hopper and survives relevant ATPSb gene, coding albumen and its application, the base Because playing critical function in maintenance brown paddy plant hopper normally survives, function, which is suppressed, will lead to the decline of brown paddy plant hopper survival rate.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of brown paddy plant hopper NlAtg3 gene, coding albumen and its Using.The present invention according toNlAtg3The protein of gene coding is relatively conservative but nucleic acid sequence and other biological homology are lower Feature carries out RNA interference to target gene, realizes the inhibition in nucleic acid level to brown paddy plant hopper, reduce brown paddy plant hopper significantly Survival rate, and avoiding may be to killing caused by non-target organism in spraying pesticide etc. that protein level uses.
Technical scheme is as follows:
A kind of brown paddy plant hopperNlAtg3Gene, for nucleotide sequence as shown in SEQ ID NO:1, which encodes ATG3 albumen, is Brown paddy plant hopper normal existence institute is required, and function, which is suppressed, will lead to the decline of brown paddy plant hopper survival rate.
A kind of brown paddy plant hopperNlAtg3The albumen of gene coding, amino acid sequence is as shown in SEQ ID NO:2, the base It will lead to the decline of brown paddy plant hopper survival rate because function is suppressed.
A kind of brown paddy plant hopperNlAtg3The application of gene is used for agricultural chemicals research and development and biological control brown paddy plant hopper.
It is a kind of for the brown paddy plant hopperNlAtg3Application of the RNA perturbation technique of gene in terms of controlling brown paddy plant hopper, institute The RNA perturbation technique stated causes the survival rate of brown paddy plant hopper to decline.
A kind of brown paddy plant hopper as mentionedNlAtg3The application of the albumen of gene coding, it is brown for agricultural chemicals research and development and biological control Plant hopper.
Beneficial effects of the present invention: (1) brown paddy plant hopper survival rate declines, and can mitigate pests to the direct of rice crop Harm.(2) nucleotide sequence and natural enemy nucleotide sequence homology lower feature of the present invention using target gene, Ke Yi RNA interference is carried out in nucleic acid level, is avoided due to the conservative injury to non-target organisms such as natural enemies of protein structure, is expected to While realizing inhibition pest, the function of bionomic control is given full play to.

Specific embodiment
ATPSb gene is a subunit of atp synthase in mitochondria, and atp synthase is responsible for the synthesis of ATP in mitochondria Journey, the disturbed synthesis (CN107988244A) that will affect ATP in mitochondria of this gene function.
NlAtg3Gene is the gene that ATG3 albumen is encoded in brown paddy plant hopper, and ATG3 albumen is cell autophagy (Autophagy) One of generating process ubiquitin-like E2 albumen, it is ethanolaminated that it is catalyzed ATG8 protein, phospholipid acyl (Phosphatidylethanolamine, PE).Cell autophagy is a kind of cell autophagy row for being prevalent in organism To be the significant process of evolution conservative in eucaryote being had enough to meet the need to intracellular matter.The egg of some damages during this White or organelle is sent into lysosome by after autophagy vesicle (autophagosome) package of double membrane structure and is degraded and followed Ring utilizes.There are many cell autophagy albumen (Autophagy-related gene, ATG) to participate in for the formation of cell autophagy corpusculum And the degradation of target protein is finally completed with lysosome fusion.Cell autophagy has played important function in insect,NlAtg3Gene is interfered, and will affect the autophagy process of insect cell, and then influence the normal growth and development of insect.
So ATPSb gene participate in be ATP in cell mitochondrial synthesis,NlAtg3What gene participated in is cell Autophagy process, two genes adhere to different cellular physiological processes separately, and as the different targets of brown paddy plant hopper prevention and treatment, the two has essence It is different.
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
