To assesse the genetic diversity among wild and cultivated accessions of 8 taxonomic groups in 2 species, and 5 subspecies under Pisum genus, and to analyze population structure and their genetic relationships among various groups of taxonomy, the study tried to verify the fitness of traditionally botanical taxonomic system under Pisum genus and to provide essential information for the exploration and utilization of wild relatives of pea genetic resources. 197 Pisum accessions from 62 counties of 5 continents were employed for SSR analysis using 21 polymorphic primer pairs in this study. Except for cultivated field pea Pisum sativum ssp. sativum var. sativum (94 genotypes), also included were wild relative genotypes that were classified as belonging to P. fulvum, P. sativum ssp.abyssinicum, P. sativum ssp. asiaticum, P. sativum ssp. transcaucasicum, P. sativum ssp. elatius var. elatius, P. sativum ssp. elatius var. pumilio and P. sativum ssp. sativum var. arvense (103 genotypes). The PCA analyses and 3-dimension PCA graphs were conducted and drawn by NTSYSpc 2.2d statistical package. Nei78 genetic distances among groups of genetic resources were calculated, and cluster analysis using UPGMA method was carried out by using Popgene V1.32 statistical package, the dendrogram was drawn by MEGA3.1 statistical package. Allelic statistics were carried out by Popgene V1.32. The significance test between groups of genotypes was carried out by Fstat V2.9.3.2 statistical package. 104 polymorphic bands were amplified using 21 SSR primer pairs with unambiguous unique polymorphic bands. 4.95 alleles were detected by each SSR primer pair in average, of which 65.56% were effective alleles for diversity. PSAD270, PSAC58, PSAA18, PSAC75, PSAA175 and PSAB72 were the most effective SSR pairs. SSR alleles were uniformly distributed among botanical taxon units under Pisum genus, but significant difference appeared in most pairwise comparisons for genetic diversity between taxon unit based groups of genetic resources. Genetic diversity level of wild species P. fulvum was much lower than the cultivated species P. sativum. Under species P. sativum, P. sativum ssp. sativum var. sativum and P. sativum ssp. asiaticum were the highest in gentic diversity, followed by P. sativum ssp. elatius var. elatius and P. sativum ssp. transcaucasicum, P. sativum ssp. elatius var. pumilio, P. sativum ssp. sativum vat. arvense and P. sativum ssp. abyssinicum were the lowest. Four gene pool clusters were detected under Pisum genus by using PCA analysis. Gene pool "fulvum" mainly consisted of wild species Pisum fulvum, gene pool "abyssinicum" mainly consisted of P. sativum ssp. abyssinicum, and gene pool "arvense" mainly consisted of P. sativum ssp. sativum var. arvense. While gene pool "sativum" were composed by 5 botanical taxon units, they are P. sativum ssp. asiaticum, P. sativum ssp. elatius var. elatius, P. sativum ssp. transcaucasicum, P. sativum ssp. elatius var. pumilio and P. sativum ssp. sativum var. sativum. "sativum" gene pool constructed the primary gene pool of cultivated genetic resources; "fulvum" gene pool, "abyssinicum" gene pool and "arvense" gene pool together constructed the secondary gene pool of cultivated genetic resources. Pairwise Nei78 genetic distance among botanical taxon based groups of pea genetic resources ranged from 7.531 to 35.956, 3 large cluster groups were identified based on the UPGMA dendrogram. Group Ⅰ equals to "sativum" and "arvense" gene pools, Group Ⅱ equals to "abyssinicum" gene pool, and Group Ⅲ equals to "fulvum" gene pool. The UPGMA clustering results generally supporting the PCA clusting results. There were significant differences among most botanical groups under Pisum genus, with clear separation of four gene pools for genetic diversity structure. The research results partially support the traditional botanical taxonomy under Pisum genus, and pointed out its advantage and shortcoming. In order to broaden the genetic bases of pea varieties, the genetic potentials in the four gene pools should be thoroughly exploited. 相似文献

T4 lysozyme was engineered with disulfide bonds and expressed in Pichia pastoris. The secreted proteins were purified and made into powder by lyophiliza-tion. Recombinant protein purity was more than 70% measured by HPLC. The lytic activity of variant T4-lysozyme was measured by the lysis of the cel wal of Xan-thomonas oryzae pv. oryzae, X. oryzae pv. oryzicola, Ralstonia solanacearum comb. nov, Clavibacter michiganensis subsp. michiganensis, X. campestris pv. mal-vacearum, Fusarium oxysporium sp. vasinfectum, Verticil ium dahliae kleb. Inhibition zone assay showed that variant T4 lysozyme significantly inhibited X. o. oryzicola and X. c. malvacearum. The antifungal activities of this protein against F. o. vasin-fectum and V. d. kleb were also analyzed. 相似文献

The random amplified polymorphic DNA marker (RAPD) was applied to detect the genetic relationships and diversity among 21 germplasm materials of Kudingcha species in Oleaceae, which involved 8 species, i.e., Ligustrum robustum (Roxb.) Blume, L. henryi Hemsl., L. japonicum Thunb, L. japonicum Thunb. var. pubscens Koidz, L. lucidum Ait., L. pedunculare Rehd, Osmanthus masumuranus Hayata, and L. delavayanm Hariot. 20 RAPD primers selected were applied for the amplification on the 21 germplasm materials mentioned above. 427 bands were obtained, and the percentage of polymorphic bands (PPB) was 97.7%. The genetic similarity coefficients (GS) ranged from 0.1522 to 0.8322 with an average of 0.5466. There was a significant genetic difference among germplasm materials of Kudingcha species in Oleaceae, and UPGMA cluster based on the GS of RAPD could distinguish all test germplasm materials clearly and indicated the relationship of the 8 species mentioned above, all of which indicated that RAPD markers could be used for the studies of genetic diversity and relationship and classification of germplasm resources of Kudingcha species in Oleaceae. Analysis results of RAPD showed that L. japonicum Thunb. var. pubscens Koidz has closer genetic relationship with L. pedunculare Rehd and further genetic relationship with L. japonicum Thunb. among all tested species. The authors suggest that further research is needed to study whether L. japonicum Thunb. var. pubscens Koidz should be classified into a variata of L. japonicum Thunb, or should be considered as an independent species. The analysis results supported that L. pururascens Y. C. Yang should be combined into L. robustum (Roxb.) Blume. 相似文献
