| biological control of wheat root diseases by the clp-producing strain pseudomonas fluorescens hc1-07. | pseudomonas fluorescens hc1-07, previously isolated from the phyllosphere of wheat grown in hebei province, china, suppresses the soilborne disease of wheat take-all, caused by gaeumannomyces graminis var. tritici. we report here that strain hc1-07 also suppresses rhizoctonia root rot of wheat caused by rhizoctonia solani ag-8. strain hc1-07 produced a cyclic lipopeptide (clp) with a molecular weight of 1,126.42 based on analysis by electrospray ionization mass spectrometry. extracted clp inhibi ... | 2014 | 24512115 |
| biological control of take-all by fluorescent pseudomonas spp. from chinese wheat fields. | take-all disease of wheat caused by the soilborne fungus gaeumannomyces graminis var. tritici is one of the most important root diseases of wheat worldwide. bacteria were isolated from winter wheat from irrigated and rainfed fields in hebei and jiangsu provinces in china, respectively. samples from rhizosphere soil, roots, stems, and leaves were plated onto king's medium b agar and 553 isolates were selected. on the basis of in vitro tests, 105 isolates (19% of the total) inhibited g. graminis v ... | 2011 | 22070279 |
