| first detection of a chloroperoxidase in bryophytes. | chlorinated cyclic bisbibenzyls of the isoplagiochin type are the first verified halometabolites from bryophytes. they could be obtained by in vitro chlorination of isoplagiochin c with chloroperoxidase from caldariomyces fumago. furthermore, an enzyme of this type was detected for the first time in bryophytes namely in the liverwort bazzania trilobata using the monochlorodimedon assay. | 2003 | 12620319 |
| bioactivity guided isolation of antifungal compounds from the liverwort bazzania trilobata (l.) s.f. gray. | a dichloromethane and a methanol extract of the liverwort bazzania trilobata showed antifungal activity against the phytopathogenic fungi botrytis cinerea, cladosporium cucumerinum, phythophthora infestans, pyricularia oryzae and septoria tritici. bioautography on thin-layer chromatograms was used to isolate six antifungal sesquiterpenes: 5- and 7-hydroxycalamenene, drimenol, drimenal, viridiflorol, gymnomitrol and three bisbibenzyls: 6 ',8'-dichloroisoplagiochin c, isoplagiochin d and 6'-chloro ... | 2004 | 15451321 |
| laser scanning reveals bryophyte canopy structure. | we evaluated laser scanning as a method to provide depth measurements for bryophyte canopies at fine spatial scales to derive surface roughness (lr), a structural parameter. depths to the first vertical canopy contact were measured on 5 x 5 cm2 areas of 27 bryophyte canopies using a contact probe, a commercial laser scanner and a scanner employing a laser diode striper (led scanner). laser scanning adequately distinguished structural types, but scanner configuration led to differences in the mag ... | 2005 | 15819931 |
| lignan derivatives from the liverwort bazzania trilobata. | eight lignan derivatives trilobatin d-k, as well as jamesopyrone were isolated from the liverwort bazzania trilobata. their structures have been elucidated based on extensive nmr spectral evidence. | 2003 | 12620330 |
| rapid detection of chlorinated bisbibenzyls in bazzania trilobata using maldi-tof mass spectrometry. | chlorinated bisbibenzyls of the bazzanin type are detected in crude bryophyte plant extracts of bazzania trilobata from different locations using maldi-tof mass spectrometry. these results show that these chlorinated compounds are not artefacts of an incidental occurrence or of the sample preparation but are genuine and produced by the liverwort or an endosymbiotic metabolism. further experiments were performed concerning the in vitro chlorination of the halogen free basic unit isoplagiochin c. | 2001 | 11382248 |
| rapid detection of multiple chlorinated bis(bibenzyls) in bryophyte crude extracts using laser desorption/ionization time-of-flight mass spectrometry. | chlorinated bis(bibenzyls) of the bazzanine type were detected in crude bryophyte plant extracts of bazzania trilobata from different locations using laser desorption/ionization time-of-flight (ldi-tof) mass spectrometry without addition of an additional chemical matrix. the degree of chlorination could be identified by the characteristic isotope patterns. these results suggest that these chlorinated compounds are not artefacts of an incidental occurrence, or of the sample preparation, but are g ... | 2001 | 11180540 |
| biosynthesis of the gymnomitrane-type sesquiterpenes in liverworts. | the biosynthesis of gymnomitranes in the liverworts reboulia hemisphaerica (l.) raddi and bazzania trilobata (l.) gray was investigated. labelling experiments with 1-13c-, 2-13c- and 6,6-d2 glucose, 2,2-d2- and 4,4-d2 mevalolactone and tissue cultures of the liverworts were carried out. | 2000 | 10746876 |
