Abstract
The invention discloses a kind of inverse correlation resistant ethane acceptor protein and the encrypt gene and the application. The protein's name is OsPK1, which has 2 cistine residue series in series table, or the derivant protein with the same activity to the former one. The encrypt gene is one of following nucleic acid series: 1)the DNA series in series table 1; 2) DAN series which has 90% similarity to the one limited in table 1 and the same encrypt function.
Description
Technical field
The present invention relates to plant ethylene receptor proteinoid and encoding gene thereof and application, particularly derive from ethylene receptor proteinoid and encoding gene and the application of paddy rice.
Background technology
Arid, saline and alkaline, damage to plants caused by sudden drop in temperature, abiotic stress such as freeze injury, waterlogging coerces factor and biotic factor such as disease and pest, growth and development of plant had material impact, can cause the extensive underproduction of farm crop when serious, cultivating the resistance of reverse crop is one of major objective of plant husbandry.Improve the resistance of reverse of crop, except utilizing traditional breeding method, at present, one of field that the molecular genetic breeding has become the scientific worker to be paid close attention to.Under the coercing of abiotic and biological adverse circumstance, higher plant cell has the number of ways impression and replys the variation of physico-chemical parameter in the external environment, the signal that born of the same parents are outer becomes intracellular signal, pass the signal along to nucleus through a series of phosphorylation cascade reactions, through the relevant functional gene of transcription factor regulation and control, start the expression of adverse circumstance response gene, improve the resistance of reverse of plant.Verified, one of signal pipeline of response abiotic and biological environment stress is relevant with ethene in the plant.
Paddy rice is illustrated the signal transmission of the ethene relational approach of its response abiotic and biological adverse circumstance, and then improves its resistance of reverse as one of most important food crop, has important theory and realistic meaning.
Summary of the invention
The purpose of this invention is to provide and anti-contrary relevant a kind of vinyl receptor protein and the encoding gene thereof of characteristic of plant.
Resistance of reverse vinyl receptor protein provided by the present invention derives from paddy rice, name is called OsPK1, be class protein, or the amino acid residue sequence of sequence 2 is passed through replacement, disappearance or the interpolation of one or several amino-acid residue and has identical active by sequence 2 deutero-protein with the amino acid residue sequence of sequence 2 with sequence 2 amino acid residue sequences in the sequence table.
Sequence 2 protein sequences are made up of 763 amino-acid residues in the sequence table, contain conservative GAF structural domain sequence, kinase domain sequence and susceptor structural domain sequence.GAF structural domain sequence be in the sequence 2 from the nitrogen end to carbon teminal 190-349 amino acids residue; The kinase domain sequence is to carbon teminal 375-615 amino acids residue from the nitrogen end; Susceptor structural domain sequence is to carbon teminal 640-756 amino acids residue from the nitrogen end.
The encoding gene of the ethylene receptor of anti-retrocorrelation proteinoid OsPK1 is one of following nucleotide sequences:
1) dna sequence dna of sequence 1 in the sequence table;
2) with sequence table in the dna sequence dna that limits of sequence 1 have 90% above homology, and the identical function protein DNA sequence of encoding.
The dna sequence dna of sequence 1 is by 2292 based compositions in the sequence table, and the reading frame of this gene is the full length DNA sequence, and it is expressed and mainly to be hurt and the inducing of high salt.
Utilize any carrier that can guide foreign gene in plant, to express, with the gene transfered plant cell of coding ethylene receptor proteinoid provided by the present invention, can obtain transgenic cell line and transfer-gen plant that biological environment stress tolerances such as arid and abiotic stress such as high salt and disease and pest are enhanced.Gene of the present invention can add any enhancing promotor or inducible promoter in being building up to plant expression vector the time before its transcription initiation Nucleotide.For the ease of transgenic plant cells or plant being identified and screening, can process employed carrier, as the antibiotic marker thing (gentamicin, kantlex etc.) that adds the alternative mark (gus gene, luciferase genes etc.) of plant or have resistance.Carry that OsPK1 expression carrier of the present invention can Ti-plasmids, Ri plasmid, plant viral vector, directly DNA conversion, microinjection, electricity be led, conventional biological method transformed plant cells or tissue such as agriculture bacillus mediated by using, and the plant transformed tissue cultivating is become plant.By the plant transformed host both can be monocotyledons, also can be dicotyledons, as: paddy rice, wheat, corn, cucumber, tomato, willow, turfgrass, lucerne place etc.Gene pairs of the present invention is cultivated the adversity resistant plant kind, particularly cultivates anti-abiotic and biological coercing as salt tolerant, disease and insect resistance plant variety, and it is significant to improve crop yield.
The present invention will be further described below in conjunction with drawings and the specific embodiments.
Description of drawings
The similarity of Fig. 1, OsPK1 and other ethylene receptor proteinoid gene relatively.
The protein structure pattern of Fig. 2, OsPK1.
Fig. 3, OsPK1 transcribe and are hurt and high-salt stress inductive RT-PCR analytical results.
Embodiment
The screening of embodiment 1, the paddy rice ethylene receptor of anti-retrocorrelation proteinoid OsPK1 and the clone of cDNA thereof
Amino acid conserved sequence with the known tobacco ethylene receptor of anti-retrocorrelation proteinoid gene NTHK1 carries out the BLAST retrieval in the paddy gene storehouse, the reads fragment that obtains through splicing, obtains the ethylene receptor of anti-retrocorrelation proteinoid gene.
Paddy rice (Oryza sativa var.Lansheng) seed kind grows to two leaves and carries out during one heart stage taking a sample after environment stress is handled in culturing room in culture dish.Collect fresh blade 1g and grind in liquid nitrogen, be suspended from the 4mol/L sulphur hydracid guanidine, mixture adds dehydrated alcohol and precipitates total RNA with acid phenol, chloroform extracting in the supernatant, afterwards, water-soluble.RNA is synthesized cDNA with reversed transcriptive enzyme.Sequences Design primer according to above-mentioned spliced gene through pcr amplification, obtains OsPK1.
OsPK1 is carried out sequential analysis, identical with the sequence that obtains in the database, as shown in Figure 1, have and ethylene receptor proteinoid NTHK1, the conservative region that NTHK2 etc. are similar.As shown in Figure 2, the aminoacid sequence of the inferring protein structure that draws according to nucleotide sequence.
The relation of embodiment 2, rice Os PK1 activity and environment-stress
Paddy rice (Oryza sativa var.Lansheng) seed kind grows to two leaves and carries out the following various processing of coercing during one heart stage in culturing room in culture dish:
Injury is handled: the paddy rice seedling is cut into 1cm length, put into water and vibrate.
Salt is handled: the paddy rice seedling is moved in the 1%NaCl solution.
Drought is handled: the paddy rice seedling is moved in 20%PEG 6000 solution.
In various processing back 0,0.5,1,3,8 hour (injury is handled) respectively; 0,3,8,24,48 hours (salt processing); 0, (drought is handled) sampling in 2,4,24 hours.Collect fresh blade 1g and grind in liquid nitrogen, be suspended from the 4mol/L sulphur hydracid guanidine, mixture adds dehydrated alcohol and precipitates total RNA with acid phenol, chloroform extracting in the supernatant, water-soluble afterwards, obtains total RNA.With OsPK1 DNA partial sequence is that primer carries out the RT-PCR analysis.Partial results as shown in Figure 3, A handles for injury among the figure; B is that 1%NaCl handles, and analysis revealed, OsPK1 are hurt and high salt is induced, but are not subjected to drought-induced.
