Abstract
The invention discloses a direct regeneration method of leaf discs of barbadosnut. The direct regeneration method comprises the following steps: leaf blades of annual barbadosnut are taken as explants and inoculated in a culture medium to directly induce adventitious buds; the culture medium is MS minimal medium which is added with 30g-L<-1> of sucrose, 4-8g L<-1> of agar, 0.2-2.0mg L<-1> of TDZ, 0.1-1.5mg L<-1> of IBA, 0.05-3mg L<-1> of BA and 0.5-8mg L<-1> of sodium nitroprusside; a culture mode: first dark culture is performed for 10-14d and then culture is performed under light for 14-16d; and finally extending culture is performed on the induced adventitious buds, and then the induced adventitious buds are transplanted after rooting culture, thus inductivity of the adventitious buds is up to 88%. The invention aims at providing an efficient regeneration method of the leaf discs of the barbadosnut in terms of genetic modification and tissue culture of the barbadosnut. The direct regeneration method has advantages of laying a foundation for realizing gene transformation and rapid propagation of the barbadosnut, and promoting industry development of the barbadosnut.
Description
Technical field
The present invention relates to the technical field of Plant Tissue Breeding, be specifically related to the direct regeneration method of leaf discs of a kind of Jatropha curcas.
Background technology
Jatropha curcas (Jatropha curcas.L.) is to be grown in the torrid zone and semi-tropical machaka or dungarunga.Jatropha curcas seed oil content height can reach 40%-60%, surpasses common oil crop such as rape and soybean, and Jatropha curcas oil can be used for various diesel engines as biodiesel, is a kind of important energy plant.But the Jatropha curcas planting area is narrow at present, only is distributed in the Asia, the torrid zone and the subtropical zone in Africa and America, and China's natural distribution has 1.1 ten thousand hm approximately
2, mainly concentrate on Sichuan, Yunnan, Guizhou.And Jatropha curcas output is lower, and the leprosy woods of artificial planting only can produce the 100-300kg fruit for every mu at present, can process the 30-100kg biodiesel approximately.Narrow distribution and yield poorly and limited it and cultivate on a large scale and industrialization as energy-source plant.Can improve resistance, the output of Jatropha curcas by engineered method, proterties such as oil, thus enlarge the Jatropha curcas distribution, increase solid output and change jatropha curcas seed oil content and oil.And fast numerous needs of genetic improvement of Jatropha curcas and improved seeds are set up leaf dish regenerating system efficiently.
Summary of the invention
The present invention is intended to provide leprosy leaf dish highly efficient regeneration method for the improvement of genes of Jatropha curcas and tissue culture.For realizing the genetic transformation of Jatropha curcas, breeding lays the foundation fast, advances the industry development of Jatropha curcas.
In order to achieve the above object, Jatropha curcas direct regeneration method of leaf discs of the present invention comprises:
A, choose in the greenhouse the 2nd, 3,4,5 of annual Jatropha curcas and launch blade, carry out being cut into 5-10mm after surface sterilization is handled as explant

The present invention has following outstanding advantage: one, and adventitious shoot regeneration speed is fast, and the leaf dish is induced through 4 times in week, promptly renewablely goes out a large amount of indefinite buds; Its two, the regeneration frequency height through inducing of 4 times in week, has 88% leaf dish to induce indefinite bud, is significantly higher than contrast, and is far above the highest level of being reported in the world, as shown in table 1; Its three, can promote the development of Jatropha curcas genetic transformation, regeneration frequency is the basis of Jatropha curcas genetic transformation efficiently; Its four, Jatropha curcas is developed as biomass energy, is of value to alleviating China and even energy energy crisis; Its five, the inventive method is easy to implement, is convenient to promote.
The present invention adjusts hormone in medium kind and hormone concentration, has particularly increased the concentration of TDZ, has also increased new plant hormone sodium nitroprussiate.TDZ is a kind of high activity class cytokinin, can obtain more desirable effect with being used of other hormones.Sodium nitroprussiate is nitric oxide donors (NO), and nitric oxide can be regulated growth and development of plant as a kind of messenger molecule, and NO also interacts with hormone influences the growth of plant.At first, the generation of basic element of cell division energy rapid stimulation NO, once more, NO can promote the formation of division of blade protoplasm somatocyte and somatic embryo again under the situation that growth hormone exists, and NO and growth hormone the interact dedifferentiation of common regulation and control plant cell and atomization again, so NO plays " bridge " effect between the basic element of cell division and growth hormone, so can promote the differentiation of indefinite bud.Changed the explant selection mode in addition, the young leaflet tablet of the different development stage by the Jatropha curcas of directly taking to cultivate in the greenhouse, increase the source of explant and obtained the maturity of the blade of suitable evoking adventive bud, use blade than last hypocotyl and cotyledon stable explant source to be arranged and can keep the proterties of choiceness as explant, and operate easier, easy to implement.
