| soil fungi of some low-altitude desert cotton fields and ability of their extracts to inhibit aspergillus flavus. | soil is presumed to be a major source of inoculum for aspergillus flavus which contaminates cottonseed and produces the potent carcinogen, aflatoxin. little is known about the mycoflora of the low desert soils of cotton fields where aflatoxin is a chronic problem. in this study, soils from cotton fields in southwestern arizona and south-eastern california were assayed for filamentous fungi. forty-two taxa, predominantly in the genera aspergillus, penicillium and fusarium, were isolated. to deter ... | 1998 | 9926421 |
| 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 |
| molecular identification of fusarium species isolated from transgenic insect-resistant cotton plants in mexicali valley, baja california. | cotton production in the mexicali valley is adversely affected by wilt and root rot disease associated with fusarium species. in the present study, we sought to isolate and identify the fusarium species in the rhizosphere of transgenic insect-resistant cotton plants grown in the mexicali valley. our analyses isolated four native fungi from the rhizosphere of cotton plants, namely, t-ica01, t-ica03, t-ica04, and t-ica08. these fungal isolates were categorized as belonging to fusarium solani using ... | 2015 | 26436498 |
| fusarium euwallaceae sp. nov.--a symbiotic fungus of euwallacea sp., an invasive ambrosia beetle in israel and california. | the invasive asian ambrosia beetle euwallacea sp. (coleoptera, scolytinae, xyleborini) and a novel fusarium sp. that it farms in its galleries as a source of nutrition causes serious damage to more than 20 species of live trees and pose a serious threat to avocado production (persea americana) in israel and california. adult female beetles are equipped with mandibular mycangia in which its fungal symbiont is transported within and from the natal galleries. damage caused to the xylem is associate ... | 2013 | 23928415 |
