| bacterial-feeding nematode growth and preference for biocontrol isolates of the bacterium burkholderia cepacia. | the potential of different bacterial-feeding rhabditida to consume isolates of burkholderia cepacia with known agricultural biocontrol ability was examined. caenorhabditis elegans, diploscapter sp., oscheius myriophila, pelodera strongyloides, pristionchus pacificus, zeldia punctata, panagrellus redivivus, and distolabrellus veechi were tested for growth on and preference for escherichia coli op50 or b. cepacia maize soil isolates j82, bcf, m36, bc2, and phqm100. considerable growth and preferen ... | 2000 | 19270990 |
| mutational bias for body size in rhabditid nematodes. | mutational bias is a potentially important agent of evolution, but it is difficult to disentangle the effects of mutation from those of natural selection. mutation-accumulation experiments, in which mutations are allowed to accumulate at very small population size, thus minimizing the efficiency of natural selection, are the best way to separate the effects of mutation from those of selection. body size varies greatly among species of nematode in the family rhabditidae; mutational biases are bot ... | 2007 | 17483403 |
| comparative evolutionary genetics of spontaneous mutations affecting fitness in rhabditid nematodes. | deleterious mutations are of fundamental importance to all aspects of organismal biology. evolutionary geneticists have expended tremendous effort to estimate the genome-wide rate of mutation and the effects of new mutations on fitness, but the degree to which genomic mutational properties vary within and between taxa is largely unknown, particularly in multicellular organisms. beginning with two highly inbred strains from each of three species in the nematode family rhabditidae (caenorhabditis ... | 2005 | 15809433 |
