Abstract
The invention relates to a method for using methanesulfonic acid carbethoxy to induce woody plant, especially using callus blast cell to induce the methanesulfonic acid carbethoxy to obtain woody plant variable kind, wherein it comprises selecting explant, processing, differentially cultivating, inducing and selecting; said explant is woody plant seed, to be cut into 1-2mm stem sections to be planted into culture medium, via differential cultivation, to induce the methanesulfonic acid carbethoxy of callus blast cell. The invention can obtain variable kind in the full expression of plant cell, with high yield. And the processed element is single cell, with small volume and high number, to reduce the cost.
Description
Technical field
The present invention relates to the method for a kind of employing ethylmethane sulfonate (hereinafter to be referred as EMS) induction mutating woody plant, especially a kind of method that adopts the callus cells,primordial to carry out the mutagenic obtained woody plant variant of EMS.
Background technology
EMS is the good mutagen of a kind of application.
P.1293-1296, periodical " Chinese herbal medicine " 2004 Vol.35 No.11 disclose a kind of catharanthus roseus cell-line mutation research of EMS mutagenesis, it studies show that: the EMS with variable concentrations handles the catharanthus roseus callus compared with the control, not only growth is fast, and indoles total alkali height, it is desired more satisfactory cell-line that variation is planted.
2003 Vol.11No.3 P.74-75 for periodical " corn science ", 84 disclose the research of a kind of EMS to the corn inbred line mutagenic effect, it studies show that: caused bigger physiological damage and biological effect in M1 generation, obvious variation does not take place for qualitative character in M2, and higher mutation frequency has appearred in the quantity shapes but plant height, fringe position are high, stem girth and spike length, blade are long etc.
As seen, the mutagenic effect of this mutagen of EMS can extensively be estimated with two-supremes one, that is: efficient height, frequency height and scope are wide.
Compare with other mutagen, the mutation frequency height that produces after the EMS mutagenesis, and mostly be dominant mutant, be easy to mutant choice.It can produce the wider mutation type of scope in addition, as conversion, transversion etc.
Using now many is to handle plant seed, pollen, seedling with EMS, growing point etc., and these generally are only limited to agricultural uses, and what carry out mutagenesis mainly is herbaceous plant such as crops.And for woody plant, such as willow, if also take these methods to obtain variant, in practical operation, just can run into many difficulties, because they are individual big, growth cycle is long, and is subjected to the low restriction of induced mutation rate, must handle the variant that numerous individualities could obtain purpose quantity, this is to be difficult to realize except that handling with cells,primordial in practical operation.
Summary of the invention
The object of the invention is to provide a kind of method of the EMS of employing induction mutating woody plant, is the mutagenesis object with woody plant callus cells,primordial, thereby solves the very much not tractable difficulty of EMS induction mutating woody plant individuality, reduces the required cost of mutagenesis.
For reaching above-mentioned purpose, the invention provides a kind of method of the EMS of employing induction mutating woody plant, with woody plant callus cells,primordial is the mutagenesis object, comprise that the selection of explant and processing, dedifferentiation are cultivated, differentiation culture, mutagenic treatment and screening again, wherein, described explant is the woody plant tissue cultivating seedling, gets the stem section that is cut into 1～2mm and is inoculated in the medium, cultivate, again behind the differentiation culture, adopt EMS to carry out mutagenic treatment through dedifferentiation.
Described mutagenic treatment method is woody plant callus cells,primordial to be soaked in the EMS treatment fluid cultivate.
Adopt the method for EMS induction mutating woody plant, choose willow callus cells,primordial, comprise the steps: as the mutagenesis object
The first step: choosing the willow tissue cultivating seedling is explant;
Second step: the stem section that the explant of choosing is cut into 1～2mm;
The 3rd step: the stem section is seeded in dedifferentiation medium MS+2, and dedifferentiation is 72～96 hours on the 4-D 0-1.0mg/ml+KT0-0.5mg/ml+NAA 0-1.0mg/ml+ZT 0-0.5mg/ml;
The 4th step: the tissue that dedifferentiation is handled well is seeded in differentiation again on the redifferential medium MS+6-BA0-1.0mg/ml+KT 0-0.5mg/ml+IAA 0-1.0mg/ml+ZT 0-0.5mg/ml, through 72～96 hours, reach and induce a large amount of time of origin sections of cells,primordial;
The 5th step:, carry out mutagenic treatment: embryo callus was soaked in the liquid differential medium that contains volumetric concentration (V/V) 1～8 ‰ EMS constant-temperature shaking culture 2～96 hours, and finished the mutagenic treatment process in the highest time period of cells,primordial incidence;
Wherein, the volumetric concentration of EMS (V/V) is 1 ‰, 2 ‰, a kind of in 3 ‰, 4 ‰, 5 ‰, 6 ‰, 7 ‰, 8 ‰.
The 6th step: clean EMS handles residual liquid, is put in the screening culture medium and screens, and obtains the used cells,primordial of willow variant, to obtain poplar mutant.
Advantage of the present invention is:
1, woody plant callus cells,primordial is handled with EMS after, obtain the regeneration plant of variation by method for tissue culture, thereby make things convenient for developing new product variety.
2, cells,primordial takes place and handles with EMS in the induction regulating controlling woody plant, obtains variant in the totipotency of plant cell is expressed;
3, the cell of a mutagenic treatment can reach in necessarily, and the cytothesis of induced gene sudden change becomes the plant of sudden change, just forms a large amount of available variants with new genetic type;
4, handle woody plant callus cells,primordial with EMS, greatly improved the induced mutation rate of handling, the individuality of processing is an individual cells, and volume is little, and number is many, and required medicine is few during processing, greatly reduces cost.
