Actinomyces strain A01 was isolated from soil of a vegetable field in the suburb of Beijing, China. According to the morphological, cultural, physiological and biochemical characteristics, and 16S rDNA sequence analysis, strain A01 was identified as Streptomyces lydicus. In the antimicrobial spectrum test strain A01 presented a stable and strong inhibitory activity against several plant pathogenic fungi such as Fusarium oxysporum, Botrytis cinerea, Monilinia laxa, etc. However, no antibacterial activity was found. In pot experiments in greenhouse, the development of tomato gray mold was markedly suppressed by treatment with the fermentation broth of the strain A01, and the control efficacy was higher than those of Pyrimethanil and Polyoxin. A main antifungal compound (purity 99.503%) was obtained from the fermentation broth of strain A01 using column chromatography and HPLC. The chemical structural analysis with UV, IR, MS, and NMR confirmed that the compound produced by the strain A01 is natamycin, a polyene antibiotic produced by S. chattanovgensis, S. natalensis, and S. gilvosporeus, widely used as a natural biological preservative for food according to previous reports. The present study revealed a new producing strain of natamycin and its potential application as a biological control agent for fungal plant diseases.

“…Isto reduz a vida útil de uma nova variedade. Nos últimos anos, várias técnicas desenvolvidas pela biotecnologia, como os marcadores moleculares, a cultura de tecidos e a engenharia genética, têm auxiliado os programas de melhoramento no sentido de detectar e gerar polimorfísmos (CORNELISSEN & MELCHERS, 1993).…”

RESUMO As plantas apresentam resistência a moléstias INTRODUÇÃOO Brasil é um país com uma enorme aptidão agrícola, com duas estações normalmente bem definidas de cultivo: o verão e o inverno. Uma das características importantes para esta vasta aptidão é a diversidade climática existente, que também favorece o surgimento de moléstias que inevitavelmente reduzem o potencial de produção, levando determinadas culturas à inviabilidade total de cultivo. O melhoramento genético visando à resistência das plantas às moléstias é uma das maneiras de controle mais eficientes, simples e de reduzido impacto na natureza. Ultimamente, devido às moléstias patogênicas terem se tomado uma grande ameaça aos campos de produção, a maioria dos programas de melhoramento tem dedicado muito tempo e recursos na busca de genótipos com alta produtividade e elevada resistência a campo. As conquistas geralmente não são muito expressivas, pois os patógenos apresentam algumas vantagens seletivas sobre os genótipos hospedeiros, entre elas: rápido ciclo de vida e facilidade de liberação de novas combinações genéticas de patogenicidade, principalmente devido às mutações espontâneas e seus mecanismos próprios de recombinação sexual ou assexual.
