group-specific differentiation of rhizobium from clover species by pcr amplification of 23s rdna sequences.	two 20-bp primers that provide group-specific detection of rhizobium spp. by polymerase chain reaction (pcr) have been used to differentiate strains that belong to different effectiveness groups within the rhizobium-trifolium cross-inoculation group. the target for dna amplification was a 370-bp fragment of the 23s rdna region. analysis of additional root-nodule forming, as well as root-associated bacterial species by pcr-primer assay revealed that variability within this 20-bp segment of the 23 ...	1998	10030005
resistance reactions to meloidogyne trifoliophila in trifolium repens and t. semipilosum.	the predominant root-knot nematode in new zealand pastures is meloidogyne trifoliophila, and a recurrent selection program in trifolium repens has developed resistance to this species. no data are available, however, on the mechanisms of resistance in t. repens or resistant genotypes of t. semipilosum. the development of m. trifoliophila in roots of t. repens and t. semipilosum was examined weekly after a 2-day inoculation with eggs. more second-stage juveniles (j2) were found in two resistant g ...	2004	19262831
