| endophytic fungal mutualists: seed-borne stagonospora spp. enhance reed biomass production in axenic microcosms. | fungal endophytes mainly belong to the phylum ascomycota and colonize plants without producing symptoms. we report on the isolation of seed-borne fungal endophytes from phragmites australis (common reed) that were ascribed to the genus stagonospora. nested polymerase chain reaction (pcr) assays revealed that a stagonospora sp. regularly colonized reed as shown for a period of three years. in spring, it was only detected in roots, whereas in autumn, it could frequently be found in all organs, inc ... | 2003 | 12848423 |
| four or more species of cladosporium sympatrically colonize phragmites australis. | a collection of cladosporium has been recovered from common reed growing at lake constance (germany). high-resolution cryo-scanning electron microscopy revealed that cladosporium isolates from reed are diverse. morphologically, we distinguished three species, viz. c. herbarum, c. oxysporum, and cladosporium sp. internal transcribed spacer (its) sequence analysis supported these results and, moreover, separated the most common species, c. oxysporum, into two subclades. two additional phylogenies ... | 2002 | 11848674 |
| perturbation and delayed recovery of the reed invertebrate assemblage in camargue marshes sprayed with bacillus thuringiensis israelensis. | bacillus thuringiensis var. israelensis (bti) is the most commonly used larvicide to control mosquitoes worldwide. considered as nontoxic to most organisms, bti can nevertheless cause trophic perturbations to natural communities by reducing the abundance of chironomidae, which are a key element of wetland food webs. since august 2006, up to 8400 of the 33 000 ha of mosquito larval biotopes in the camargue (rhône delta, in southern france), are monitored by a public agency and bti-sprayed (aqueou ... | 2016 | 27794203 |
