Isolation, purification and identification of three peptaibols from Trichoderma koningii with antibiotic activity against Ralstonia solancearum

The use of microorganisms for biological purposes has become an effective alternative to control plant pathogens. Trichoderma koningii Smf2 was chosen from eight Trichoderma strains for its thermostatic metabolites with antibiotic activity against Ralstonia solancearum Smith. Exclusion chromatography (LH20) was used twice to partially purify targeted metabolites combined with biological test. LC/ESI-MS, a powerful tool for rapid identification and sequence determination of peptides,…     

楸树组织培养研究进展

楸树是我国原产树种,具有丰富的价值,由于其自花不育实生繁殖较为困难。组织培养为楸树的基因工程提供了基础,可在短时间内获得幼稚的大规模苗木。为扩大楸树的生产应用,本文从外植体的的选取,初代芽诱导、增殖培养、生根等方面的研究现状进行了概述,旨在为快速建立楸树的高效组培繁育体系技术提供参考。
