Abstract

The invention discloses an insect-resistant gene and glyphosate-resistant gene expression vector and application thereof, wherein the expression vector contains an insect-resistant gene cry1Ab, an insect-resistant gene cry2Ae and a glyphosate-resistant gene cp4. According to the invention, a chloroplast signal peptide sequence is added in front of the Cry2Ae gene, so that on one hand, the expression quantity of Cry2Ae protein is increased, and the increase amplitude is 20% -100%; on the other hand, the interference of the Cry2Ae protein with high expression quantity on the growth and development of plants is reduced. Meanwhile, the carrier simultaneously expresses Cry1Ab, cry2Ae and Cp4 proteins, and transgenic crops obtained by transforming crops with the carrier can simultaneously resist main lepidoptera pests of crops such as Spodoptera frugiperda, cotton bollworm, beet armyworm, corn borer, chilo suppressalis and the like, thereby widening the insect-resistant range of the transgenic crops, effectively delaying the generation of pest resistance and simultaneously enabling the transgenic crops to have the capability of resisting glyphosate.

Description

Insect-resistant gene and glyphosate-resistant gene expression vector and application thereof
(I) the technical field
The invention belongs to the field of cultivation of new varieties of transgenic plants, and particularly relates to an expression vector for simultaneously and efficiently expressing two insect-resistant genes and a glyphosate-resistant gene and application thereof in cultivation of insect-resistant and glyphosate-resistant plant cells and plants.
(II) background of the invention
The rapid global population growth has driven a substantial increase in food demand. In fact, grain production has been significantly increased over the past few decades by conventional variety improvement and cultivation technology improvements, particularly the use of pesticides. The cellular genetics and the cellular biology technology which arose in the last 60 s of the century triggered a green revolution, which significantly improved the yield of grain crops and significantly enhanced the disease and insect resistance. However, the widespread adoption of these technologies also brings new problems to the environment and human health, such as increased soil erosion due to the use of pesticides and fertilizers. Meanwhile, after the technologies are used for 20 years, the contribution to grain yield increase is also obviously reduced. To overcome these problems, scientists from governments, universities, research institutions, and corporations are seeking new techniques and methods. With the rapid development of DNA technology, scientists have developed new modern breeding techniques and methods up to the last 80 th century, of which transgenic technology using agrobacterium-mediated transformation and biolistic transformation was the most successful.
With the development of biotechnology and the increase of investment of various countries in the field of biotechnology, global breeders and biotechnology research institutions can break through the traditional breeding framework and breeding years to cultivate new plant varieties. The approval of the commercial planting of transgenic insect-resistant cotton was approved in the united states in 1995, the promotion of transgenic insect-resistant cotton was started in 1996, and the introduction of transgenic insect-resistant cotton was started in 1996 in china. In 2019-2021, agricultural transgenic organism safety certificates of insect-resistant herbicide-tolerant corn and soybean are examined and approved for the first time in China, and the fact that transgenic organism breeding technology enters an accelerated stage is marked. In addition, spodoptera frugiperda has invaded China from Yunnan in 2018-2019 as a omnivorous pest, the pest is high in harmfulness and strong in drug resistance, and has serious harm to crops such as corn in China at present, and the pest such as Spodoptera frugiperda is urgently prevented and treated by a biological breeding method.
Bacillus thuringiensis (Bacillus thuringiensis) is a common gram-positive soil microorganism that produces an insecticidal protein with high selectivity for a particular organism. The safety test for Bt protein has been carried out for decades, and it is non-toxic to human and animals. The Cry1Ab gene is cloned from Bacillus thuringiensis HD-1 strain, and its expression product Cry1Ab protein has broad spectrum insecticidal activity in Lepidoptera pests (Hfte H and Whiteley H R. Microbiological Reviews,1989,53 (2): 242-255.; van Frankenhuyzen K. J Invertebr Pathol 2009,101 (1): 1-16). By 1 month 2012, a total of approximately 70 Cry2 proteins were identified, covering a9 subclass from Cry2Aa to Cry2Ai, and the majority of the Cry2Ae class, with Cry2Ae proteins being only toxic to lepidopteran insects, and Cry2Ae being more virulent than Cry2Aa to cotton bollworms of america (Zheng a et al. Although the molecular weight of the Cry2 protein is smaller than that of Cry1, the Cry2 has wider insecticidal range to lepidoptera compared with Cry1 toxin, and has asymmetric cross resistance with Cry1, so that the Cry2 protein has a greater application prospect in the aspect of agricultural pest control. In recent years, second generation transgenic plants based on cry2Ae monovalent gene or cry2Ae + cry1Ac bivalent gene are gradually replacing first generation transgenic plants based on cry1A type gene to alleviate the adaptation of target pests to insect-resistant plants and the risk of resistance, such as transgenic cotton Bollgard II (Tabashnik B E et al. Appl. Environ. Microbiol.2002,68 (8): 3790-3794.). The Cry1Ab has extremely low amino acid similarity with a Cry2Ae protein functional region, and is only 17.9 percent. Therefore, the two have greatly different insecticidal spectrums, are not easy to generate delivery resistance, and are very suitable for combined use.
Weeds are the second most important factor affecting crop production. It competes with crops for water resources, fertilizers, light sources, etc., causing a decrease in crop yield and also reducing the quality of agricultural products. The traditional manual weeding method is time-consuming and labor-consuming, has low efficiency and high mechanical weeding cost, and chemical weeding has high technical requirements and extremely high possibility of causing phytotoxicity to plants, influencing the growth and development of the crops, and simultaneously possibly influencing adjacent sensitive crops.
At present, transgenic approaches to glyphosate tolerance in plants are the most widely used weed solution. The glyphosate, the chemical name of which is N- (methyl phosphate) glycine, is an organic phosphine herbicide, is a systemic conduction type broad-spectrum biocidal herbicide, and has long-term safe use records of more than 40 years. The glyphosate-tolerant trait can be conferred on plants by expressing EPSPS genes such as CP4 (derived from Agrobacterium CP4 strain, encoding CP4EPSPS protein) (Patgette, SR et al 1996.Pages 53-84in Herbicide-Resistant Crops) and genes such as Gat (derived from glyphosate N-acetyltransferase of soil microorganism metagenome) which can express enzymes degrading glyphosate.
The method for simultaneously expressing multiple target proteins by plants mainly comprises a multiple expression frame molecule cloning and stacking method, a hybridization stacking method and a gene fusion method, wherein the multiple expression frame molecule cloning and stacking method is widely used due to the advantages of good stability, strong predictability, easy plant transformation in the later period and the like. The effect of the multiple expression cassette stacking strategy is influenced by many factors, including gene selection, coding sequence selection, selection of regulatory elements including promoters, terminators, etc., for each expression cassette, and the arrangement of reading frames. These factors all have different effects on the expression level and stability of the target gene among different generations of expression patterns, especially on the condition of high-generation gene silencing. Therefore, an expression vector capable of efficiently and stably expressing a plurality of target genes needs to be strictly explored and tested, and the vector plays a decisive role in obtaining stable and efficient transgenic crops.
Disclosure of the invention
The invention aims to provide a binary vector for stably and efficiently expressing insect-resistant genes (cry 1Ab and cry2 Ae) and glyphosate-resistant genes (cp 4 genes) at the same time, and application thereof in preparing insect-resistant and glyphosate-resistant plant cells and crops, so that corresponding transgenic crops have wider insecticidal spectrum, the generation resistance of insects to insecticidal proteins is delayed, and the insects are simultaneously glyphosate-resistant.

The expression vector of the invention constructs two insect-resistant protein coding genes cry1Ab and cry2Ae with very low homology and a glyphosate-resistant gene cp4 into the same plant expression vector, so that corresponding transgenic crops have wider insecticidal spectrum, the generation of resistance of insects to insecticidal proteins is delayed, and the glyphosate-resistant genes are simultaneously glyphosate-resistant. The carrier can transfer the three genes into a receptor plant at the same time, so that the plant has the characteristics of resisting the main lepidoptera pests such as spodoptera frugiperda, cotton bollworm, spodoptera exigua, corn borer and the like and resisting glyphosate herbicide. Cry1Ab has good killing effect on spodoptera frugiperda, ostrinia nubilalis and other lepidoptera pests, and can effectively solve the control problem of main lepidoptera pests of crops by combining the excellent killing effect of Cry2Ae on cotton bollworms and other lepidoptera pests. In particular, spodoptera frugiperda has invaded China from Yunnan in recent years, and the character of the vector endowed with plants is very critical to effectively controlling spodoptera frugiperda.

Plant Cell Reports, 2003.), cassava veinmosaicvirus (CsVMV) promoter, australianbannanacarea virus (BSV) promoter, mirabilismosis virus (MMV) promoter, and the like. In addition, the expression of a target gene can be enhanced by using elements such AS enhancers and introns, for example, MAR (Matrix attachment regions) sequence of tobacco (Dolgova AS, dolgov SV.Biotech.2019,9 (5): 176.), intron of rice actin gene (Oszvald M et al Biotechnology and Bioprocess Engineering,2007,12 (6): 676-683.), intron of maize HSP70 gene, etc. (Brown S M, santino C G.CA2100A1.1993).

Example 6 acquisition of transgenic insect-resistant herbicide-tolerant soybeans
The procedure used here to obtain transgenic soybeans is from the established art (Deng et al plant Physiology communications.1998,34, 381-387, ma et al science Agricuicura Sinica.2008, 41-668, zhou et al journal of northern Agricultural university.2001, 32. Healthy, full and mature soybeans of 'Tianlong No. 1' are selected, sterilized by 80% ethanol for 2 minutes, washed by sterile water and then placed in a dryer filled with chlorine (generated by the reaction of 50ml of NaClO and 2ml of concentrated HCl) for sterilization for 4-6 hours. Spreading sterilized semen glycines in B5 culture medium in clean bench, culturing at 25 deg.C for 5 days with optical density of 90-150 μmol photon/m 2 S level. When the cotyledon turns green and breaks the seed coat, the aseptic bean sprouts grow. The bean sprouts with the hypocotyl removed were cut into five-five pieces in length so that two pieces of explants had cotyledons and epicotyls. The explants are cut at about 7-8 of the node of the cotyledon and epicotyl and can be used as the target tissue to be infected.
Monoclonal agrobacteria containing the vector 1300-p35S-intron-cp4-pZmUbi1-cry1Ab-pZmUbi2-cry2Ae prepared in example 3 and 1300-p35S-intron-cp4-pZmUbi1-cry1Ab-MAR-pZmUbi2-cry2Ae were separately cultured for use. The prepared explants were immersed in the Agrobacterium suspension and co-incubated for 30 minutes at 28 ℃. Then, the excess cell suspension on the infected tissue is absorbed and cleaned by absorbent paper, and then transferred to 1/10B5 co-culture medium for dark culture at 25 ℃ for 3-5 days.
The co-cultured plant tissue was washed with B5 liquid medium to remove excess Agrobacterium, and then placed in B5 solid medium for 5 days at 25 ℃ until it germinated. The induced germ tissue was transferred to B5 selection medium containing 0.5mM glyphosate and incubated at 25 ℃ with light for 4 weeks, during which the medium was changed every two weeks. Transferring the selected embryo tissue to a solid culture medium, culturing at 25 deg.C, and growing into plantlet. Subsequently, transgenic plants were transferred to 1/2B5 medium for rooting induction. Finally, the grown plantlets are washed to remove agar and planted in a greenhouse.
