host plant recognition by the root feeding clover weevil, sitona lepidus (coleoptera: curculionidae).this study investigated the ability of neonatal larvae of the root-feeding weevil, sitona lepidus gyllenhal, to locate white clover trifolium repens l. (fabaceae) roots growing in soil and to distinguish them from the roots of other species of clover and a co-occurring grass species. choice experiments used a combination of invasive techniques and the novel technique of high resolution x-ray microtomography to non-invasively track larval movement in the soil towards plant roots. burrowing distan ...200415385062
diverse bacteria isolated from root nodules of trifolium, crotalaria and mimosa grown in the subtropical regions of analyze the diversity and relationships of rhizobia in the subtropical and tropical zones of china, we characterized 67 bacterial strains isolated from root nodules of five legume species in the genera trifolium, crotalaria and mimosa . pcr-amplified 16s rdna rflp, numerical taxonomy, sds-page of whole cell proteins, sequencing of 16s rdna and dna-dna hybridization grouped the isolates into 17 lineages belonging to bradyrhizobium, mesorhizobium, rhizobium, sinorhizobium and burkholderia, as w ...200717497134
[different nacl-dependence of the circadian co2-gas-exchange of some halophil growing coastal plants].co2-exchange, diurnal changes in malate- and ion concentrations of the halophytes carpobrotus edulis, crithmum maritimum, mesembryanthemum nodiflorum, salicornia fruticosa, suaeda maritima, and trifolium fragiferum were investigated after culture at different nacl concentrations. in carp. edulis and mes. nodiflorum the diurnal rhythm of co2-exchange is in accordance with that of crassulacean acid metabolism (cam), in sal. fruticosa, crithm. maritimum, suaeda maritima, and trif. fragiferum with t ...197428308642
