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 phylogenic and genetic relationships in germplasm resources of Chinese Ziziphus were studied at molecular levels, for providing new molecular evidences of classification, protection, and utilization of germplasm resources of Ziziphus. The sequence-related amplified polymorphism （SRAP） was assessed to analyse the genetic relationships among 14 species of Ziziphus, 11 cultivars of Z. jujuba Mill., and one outgroup. A total of 580 DNA bands were amplified by 19 selective primers, 570 of which （98.28%） were polymorphic. The average number of polymorphic DNA bands amplified by each primer was 30. The genetic similarities of 26 sample materials were between 0.22 and 0.99. UPGMA method cluster analysis showed that 26 sample materials were classified into six cluster groups with the genetic similarity of 0.28. The results showed that SRAP technique is efficient in studying genetic relationships among Ziziphus, Z. jujuba Mill. and Z. acidojujuba C. Y. Cheng et M. J. Liu which should be treated as one species, and further infraspecific classification of Z. jujuba Mill. should be classified into two subspecies; the scientific names of new taxa, Chinese jujube, and wild jujube were Ziziphus jujuba Mill. subsp, jujuba and Ziziphus jujuba Mill. subsp, spinosa （Bunge） J. Y. Peng, X. Y. Li et L. Li, respectively. Z. xiangchengensis Y. L.Chen et P. K. Chou, Z. montana W.W. Smith and Z. mairei Dode might be originated from same ancestry. Z xiangchengensis Y. L. Chen et P. K. Chou and Z. montana W.W. Smith should be treated as one species. The infrasubspecific taxon of Z. jujuba Mill. was not suitable to set up varieties. 相似文献

湖南茶树资源类型亲缘关系及其分类学位置的探讨 总被引：1，自引：0，他引：1
陈国本 《湖南农业大学学报(自然科学版)》1987,(3)
依据形态学特征,结合细胞学,酶学特点对湖南四个茶树种群进行了亲缘关系研究。参照《茶叶植物资源订正》、《国际栽培植物命名法规》以及《山茶属修订》,提出了湖南四个茶树种群的分类学位置。四个种群的亲缘性依次为:安化、江华,城步、汝城。四个种群都属于C.sinesis(L).O.Kuntze.安化种群(云台山大茶叶):C.sinensis(L)O.Kuntze CV.Yuntai shanesis江华种群(江华茶):C.assamica Chang CV.Jianghua=C.sinensis(L)O.Kuntze CV.Jinghua;城步种群(峒茶):C.assamica Chang CV.Duntsa=C.Sinensis(L)O.Kuntze CV.Dimtsa:汝城种群(毛叶茶):C.ptilophylla chang CV.Lasiocalyx(C.ptilophylla Chang F.Lasiocalyx).上述结果为茶树资源的利用提供了理论和实践依据。 相似文献
