Phylogenetic Relationships Among Fortunella Swingle And Its Relatives As Revealed By ISSR And SSR Markers

Fortunella belongs to Rutacease .Aurantioideae ,Citreae .Citrinae. It is one of the most well-known special products in China with strong fastness and wild flexibility. It also contains the feature such as extensive adaptation, convenient edibility. Fortunella is one of a very famous fruits which only products in our country. What's more, it can be produced from southernmost district to the northernmost brink, spreading all over the distribution of orange. Meanwhile, Oval Kumquat can be widely used to process the leisure food, such as succade, beverage, tin, fruit juice, fruit wine, and so on. Ben Cao Gang Mu said that it's fructification tastes tartness,pleasant,Lukewarm;it also can be used to dispel drank,antithirsty,deodorization.The investigation of morden iatrology showed that Fortunella's fructification have the ability of intenerate the blood vessel ,cure hypertension, accommodate circadian dysfunction.The research also showed that the Limonoids which enrichment in Fortunella can cure knub,place a premium on vivid of Glatathione-s-transferasc. For that case.it can even refrain the infection from chemical materials that lead to cancer. Fortunella is the third generation of fruits typically.Our country, as the original center of Fortunella, in addition, the largest cultivated and grown center at present of the world, is in the possession of the whole style.But the research of Fortunella still relies on cultivation,management,palynology,isozyme and so on.The research on both genetic diversity investigation and idioplasm evaluation systematically are still absent.The crossbreed of Fortunella and it's close assessions can raise offspring.and there is still a great deal of new style brought up during the history of artificial cultivation.The condition is not only do harm for the evaluatiation and preservation but also do harm for the breeding and varity protection in Fortunella.Concerning the problem of Fortunella research, the study is engaged in Fortunella and its close species with SSR and ISSR molecular markers.The research utilize 10 accessions from 5 out of 6 Fortunella species besides the Long-leaf Kumquat and some of its close assessions.Phylogenetic relationships among these assessions belonging to Fortunella and its close species were investigated using ISSR and SSR markers. This relationship may offer the theory to help people to identify the resource of Fortunella.and also to preserve and utilize the Fortunella resource.At the same time,the reaction system of ISSR and SSR molecular markers' and its fingerprints may also help people to...
