2, electrophoresis detection
Get above-mentioned amplified production 20ul, the sepharose with 4.0% (containing 0.5%ug/ul EB) electrophoresis, ultraviolet lamp are observed down and the photographic recording result.
We utilize 3 pairs of STS primers that CJ06 and TN1 are carried out polymorphism analysis, wherein have 1 pair of primer to show polymorphism between parents.Further primer is carried out the STS analysis to CJ06, TN1 and its filial generation individual plant, find that STS primer AP4741 all has the same banding pattern of pest-resistant parent CJ06 in all pest-resistant filial generation individual plants with this.Illustrating that the anti-white backed planthopper characteristic of STS primer AP4741 and paddy rice exists gets in touch.
The AP4741 primer sequence is: left wing 5 '-AAT CAT GCT AGG TTA TTA CTC G-3 ' (SEQ ID NO:3), right flank 5 '-GTG CAG AGA TCA TGC TTT TG-3 ' (SEQ ID NO:4) is positioned on paddy rice the 6th karyomit(e).
Three, the linksystem of STS molecule marker AP4741 is identified
CJ06 and TN1 parents and offspring's thereof white backed planthopper resistance is identified and is carried out in the field, under the spontaneous induction condition of field, carry out the insect-resistance evaluation from aspects such as the borer population of moving into, honeydew secretory volume, insect pest generation density and killed degree to parents and offspring's segregating population respectively in early days in tillering; Extract total DNA of recessive pest-resistant individual plant, with reaction system and the program same with the front, carry out the pcr amplification of individual plant with primer AP4741, statistics resists, feels the frequency of occurrences and the switch type of individual plant indicia band and calculates crossover value, with the genetic distance between MapnakerEXP3.0b calculating mark and the anti insect gene.With AP4741 76 individual plants of filial generation colony are carried out pcr amplification, amplification condition is the same.The result shows to have the banding pattern of 71 individual plants the same with pest-resistant parent CJ06 in 76 pest-resistant individual plants, has the banding pattern of 5 individual plants to have parents' banding pattern simultaneously, discovery and feels the same individual plant of worm parent's TN1 banding pattern.This experimental result shows: the white backed planthopper resistance of STS molecule marker AP4741 and paddy rice is closely linked, but still has certain exchange in pest-resistant individual plant, shows as Fig. 3, and the individual plant that parents' banding pattern occurs shows exchange has taken place.As calculated, its recombination fraction is 3.3%, and the genetic distance between STS molecule marker and anti insect gene is 3.3cM.
At last, it is also to be noted that what more than enumerate only is several specific embodiments of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
