| Notes | 51-1213/S Objective] The AMF diversity and composition structure of roses root were studied in this paper. [ Method] Three ＇ Rosa Carola＇plant were randomly collected from germplasm resources gardon of Kunming college. The roots DNA were extracted using CTAB method andAMF partial 18S rRNA gene were amplified by Nested-PCR. The DNA mixture was used to construct AMF clone library. Finally, thirty posi-five clones were chosen for sequencing and analyzed. Meanwhile, e/one library was evaluated and analyzed in this paper. [ Result1 CoverageC value of the library was 70.0 %, but the rarefaction curve was not saturated, and the number of library clones should be increased. TheShannon index and Simpson index was 1. 432 and 0.25, respectively, and the species richness was 4. O. Sequences with 〉98 % similaritywere assigned to the same OTUs. Totally, 30 sequences were divided into 15 OTUs and all of them belonged to Glomus. Among them, OTU1was the main type of library, OTU2 - OTU9 represented the common types, while OTUI |
