| correlations between root-associated microorganisms and peach replant disease symptoms in a california soil. | replant disease often occurs when certain crops are "replanted" in a soil that had previously supported the same or similar plant species. this disease typically leads to reductions in plant growth, crop yields, and production duration, and its etiology remains ill-defined. the objective of this study was to identify microorganisms associated with peach replant disease symptoms at a field location in california, usa. soil samples were subjected to treatments to create various levels of replant d ... | 2012 | 23071565 |
| races of the celery pathogen fusarium oxysporum f. sp. apii are polyphyletic. | fusarium oxysporum species complex (fosc) isolates were obtained from celery with symptoms of fusarium yellows between 1993 and 2013 primarily in california. virulence tests and a two-gene dataset from 174 isolates indicated that virulent isolates collected before 2013 were a highly clonal population of f. oxysporum f. sp. apii race 2. in 2013, new highly virulent clonal isolates, designated race 4, were discovered in production fields in camarillo, california. long-read illumina data were used ... | 2017 | 27938244 |
| phylogeny and pathogenicity of fusarium oxysporum isolates from cottonseed imported from australia into california for dairy cattle feed. | a unique biotype of the fusarium wilt pathogen, fusarium oxysporum schlecht. f.sp. vasinfectum (atk) sny. & hans., found in australia in 1993 is favored by neutral or alkaline heavy soils and does not require plant parasitic nematodes to cause disease. this makes it a threat to 4-6 million acres of usa upland cotton ( gossypium hirsutum l.) that is grown on heavy alkaline soil and currently is not affected by fusarium wilt. in 2001-2002, several shiploads of live cottonseed were imported into ca ... | 2011 | 22004096 |
