formation of structures resembling ericoid mycorrhizas by the root endophytic fungus heteroconium chaetospira within roots of rhododendron obtusum var. kaempferi. | a resynthesis study was conducted to clarify the relationship between the root endophyte, heteroconium chaetospira and the ericaceous plant, rhododendron obtusum var. kaempferi. the host plant roots were recovered 2 months after inoculation, and the infection process and colonization pattern of the fungus were observed under a microscope. the hyphae of h. chaetospira developed structures resembling ericoid mycorrhizas, such as hyphal coils within the host epidermal cells. these structures were m ... | 2005 | 15517420 |
the development and endophytic nature of the fungus heteroconium chaetospira. | the root endophytic fungus heteroconium chaetospira was isolated from roots of chinese cabbage grown in field soil in japan. this fungus penetrates through the outer epidermal cells of its host, passes into the inner cortex, and grows throughout the cortical cells, including those of the root tip region, without causing apparent pathogenic symptoms. there are no ultrastructural signs of host resistance responses. h. chaetospira has been recovered from 19 plant species in which there was no disru ... | 2005 | 16168582 |
a mutualistic symbiosis between a dark septate endophytic fungus, heteroconium chaetospira, and a nonmycorrhizal plant, chinese cabbage. | symbiotic microorganisms, such as mycorrhizal fungi, are known to associate with most plants; however members of the cruciferae are an exception. we investigated nutrient exchange between a dark septate endophytic fungus, heteroconium chaetospira, and chinese cabbage plants (cruciferae) in vitro. chinese cabbage could not use some amino acids, while the fungus-treated plants were able to use all of the nitrogen forms provided. to demonstrate that nitrogen transfer occurs between the fungus and t ... | 2007 | 17682770 |
control of verticillium yellows in chinese cabbage by the dark septate endophytic fungus ltvb3. | abstract three hundred forty-nine fungal endophytes were obtained from a total of 1,214 root segments of eggplant, melon, barley, and chinese cabbage grown as bait plants in a mixed soil made up of samples from different forest soils in alberta and british columbia, canada. three of the 349 isolates, when inoculated in axenically reared chinese cabbage seedlings grown in petri dishes, almost completely suppressed the effects of a postinoculated and virulent strain of verticillium longisporum. tw ... | 2004 | 18943758 |
