The nucleotide sequence of the cotton ghNAC4 transcription factor gene is shown by SEQ ID NO.1; a ghNAC4 binary expression vector is constructed; the cotton is transformed by using agrobactrium tumefaciens to obtain ghNAC4 gene cotton; the transcription ghNAC4 gene cotton is verified by using drought simulation experiment and is provided with drought resistance due to over-expression of the ghNAC4.
Description
Technical field
The present invention relates to plant genetic engineering field, relate in particular to one grow cotton the ghNAC4 transcription factor gene with and the plant expression vector that makes up and in the application aspect the drought-enduring transgenic plant rearing new variety.
Background technology
Transcription factor is claimed trans-acting factor again, and being a group energy combines with cis-acting elements generation specificity in the eukaryotic gene promoter region, thereby guarantees that goal gene is with specific intensity, at specific time and space expressed protein molecule.When plant experiences extraneous arid, high salt, hormone, disease; Through a series of signal transmission; Excite transcription factor, transcription factor is with after corresponding cis-acting elements combines, activator RNA polymerase II transcription complex; Thereby start the transcriptional expression of specific gene, the effect through gene product at last internally, the conditioned reaction made of outer signals.The many expression of gene of plant all are to be interacted by specific transcription factor and specific cis-acting elements.
Transcription factor is being played the part of very important role in plant defense and environment stress answering.Obtain remarkable progress aspect the gene clone of plant transcription factor and the functional study in recent years, also identifying the multiple cis-acting elements that combines with transcription factor simultaneously, for example: G box, W box, CRT/DRE, MYC-like.Transcription factor is through combining and the direct regulation and control target gene expression with the cis-acting elements of the downstream gene promoter region of its regulation and control; Or form homology, heterodimer; Or become certain activated form with other interactions between protein and participate in signal transduction paths such as JA, SA, ABA, form the regulated and control network of genetic expression.According to research to MYB class, bZIP class, WRKY class, AP2/EREBP class and NAC class plant transcription factor family member; The result shows that they have regulated and control relevant physiological response gene expressed proteins and in plant defense and adverse circumstance signal transduction, played a role, thereby makes plant adapt to extraneous poor environment.Wherein, WRKY class and AP2/EREBP class transcription factor are the peculiar transcription factors of plant, but regulation and control during downstream gene expression and other transcription factors general character is arranged, all be through combine to induce degeneration-resistant reaction to reply with cis-acting elements.
Transcription factor improves the method for certain resistance and compares in improving the molecular breeding of crop to tolerance to environmental stress with importing or improvement discrete function gene, importing or improve a transcription factor is to improve more efficiently method of crop anti-adversity and approach.Handle a transcription factor and just can impel a plurality of functional genes to play a role, thereby reach the effect that makes tree characteristics obtain comprehensive improvement through it.
The NAC transcription factor is a newfound plant specific transcriptional regulator over past ten years.Aida in 1997 etc. have at first reported the NAC structural domain, and the N end of finding at petunia NAM gene, Arabidopis thaliana ATAF1/2 and CUC2 gene coded protein comprises one section conservative aminoacid sequence, gets three gene initial called after NAC.First NAC transcription factor is equaled from petunia, to clone in 1996 by Souer and obtains; In species such as Arabidopis thaliana, paddy rice, wheat, soybean, find in succession subsequently; In Arabidopis thaliana, find 105 NAC members at present altogether, then found 75 in the paddy rice.Research shows, the NAC transcription factor is built up at growth and development of plant, organ, hormone regulation and defence are resisted aspects such as multiple biology and abiotic stress and brought into play important effect.
The NAC transcription factor receives multiple biology to coerce the abduction delivering with abiotic stress, the stress response of involved in plant.A paddy rice drought resistance and salt tolerance gene SNAC4 has cloned in the Xiong Lizhong of Hua Zhong Agriculture University professor research group; This gene is the transcription factor of NAC type, its mainly in the stomata guard cell of pore by abduction delivering, promote stomatal closure during drought stress; But do not influence photosynthetic rate; Thereby drought resistance greatly improves, and under the situation of reproductive stage severe drought, the transfer-gen plant fruit-setting rate of overexpression SNAC4 contrast improves 22%～34%; In vegetative growth phase, transfer-gen plant also shows very strong drought resistance.A drought-induced Gene A TAF1 has cloned in the Wang Xuechen of China Agricultural University professor research group in Arabidopis thaliana, this gene also is the transcription factor of NAC type.The expression of ATAF1 receives inducing of arid and ABA processing, under the situation of watering, is suppressed again.Knock out the two mutants ataf1 of ATAF1 gene; Recovery rate is 7 times of normal control in the reaction test that waters behind drought stress; And 6 known drought-induced genes (RD17, ERD10, KIN1, RD22, COR78 and LT178) expression level improves; The ATAF1 gene is described as negative regulation, is worked through regulating being expressed in the drought resisting reaction of osmotic stress response gene.The NAC transcription factor that has can with the MYC-like combination of elements, the core sequence of this element (CATGTG) plays an important role in the drought-induced reaction answering of Arabidopis thaliana ERD1.Employing yeast one-hybrid technology such as Tran are separated to 3 different NAC genes (ANAC019, ANAC055 and ANAC072) from Arabidopis thaliana, their expression receives inducing of arid, high salt and ABA, and overexpression can significantly strengthen the drought-resistance ability of transfer-gen plant.And ANAC072 (RD26) participates in the adverse circumstance signal transduction path of ABA mediation; Overexpression RD26 can significantly strengthen the susceptibility of transfer-gen plant to ABA; Find simultaneously ABA and adverse circumstance factor inductive gene in transfer-gen plant also by up-regulated expression, it is then opposite suppress to express RD26.
Discovery such as Delessert Arabidopis thaliana transcription factor ATAF2 is the height abduction delivering at the blade injury position, and plant hormone methyl jasmonate (mj) and the Induced by Salicylic Acid reaction that relates to damage responded, but to not reaction of dormin; Overexpression ATAF2 has suppressed the expression of some pathogenesis-related proteins, and plant descends to the resistibility of autochthonal sickle mycete, explains that ATAF2 works in defensive raction as negative regulation of pathogenesis-related protein.Hegedus etc. have made up the mixing cDNA library that rape leaf is bitten by physical abuse, beetle to nibble and damage to plants caused by sudden drop in temperature processing; And from this library, filter out 8 NAC class transcription factors; Wherein 5 transcription factors are similar with the ATAF1 or the ATAF2 of Arabidopis thaliana; Their ectopic expressions in the model plant Arabidopis thaliana, are caused heteroplasia, be similar to Arabidopis thaliana nam and cuc two mutants; Characteristics such as the strain system of overexpression BnNAC44 shows blade and increases, and stem chap and lateral root are in great numbers, this NAC4 gene function with Arabidopis thaliana is similar.Oh etc. are separated to a kind of NAC class transcription factor CaNAC4 from capsicum, this transcription factor receives inducing of pathogenic bacteria, external source Whitfield's ointment and ethene.This shows that the NAC transcription factor plays an important role among the multiple degeneration-resistant signal pathway of plant.
