促植物生长根际细菌(Plant growth-promoting rhizobacteria,PGPR)是指定殖于植物根际土壤的一类可促进植物生长的益生细菌.一般认为,PGPR对植物吸收利用矿物质营养有促进作用,可有效抑制土壤中有害病原微生物和非寄生性根际有害微生物,还可产生多种生物活性物质,从而表现出促进植物生长、提高作物产量、增强植物抗逆(病)性、控制植物病害和土壤修复等多种生物学功能(Klo
谭小艳等从广西合浦县柑橘叶片表面分离获得一株对柑橘溃疡病菌(Xanthomonas axonopodis pv.citri)具有较强拮抗作用的枯草芽孢杆菌菌株Bv10.研究发现,除Xanthomonas spp.外,菌株Bv10对多种植物病原真菌也有不同程度的抗菌活性.为深入了解菌株Bv10抗菌活性的物质基础,作者以芝麻白绢病菌Athelia rolfsii作为指示菌,对菌株Bv10产生的胞外抗菌
番茄溃疡病是番茄生产中最为严重、具有毁灭性的病害之一.该病自从1909年首次在美国密执安州的温室番茄上发现以来,现已广泛分布于美国各番茄产区,并逐渐成为世界性病害.其病原菌为密执安棒杆菌密执安亚种,即Clavibacter michiganensis subsp.michiganensis,简称Cmm.目前,在美洲、欧洲、亚洲、非洲和大洋洲的多个国家都有番茄溃疡病发生为害的报道.我国有关番茄溃疡病
