Lysogeny and bacteriocinogeny in Xenorhabdus nematophilus and other Xenorhabdus spp.
Induction by mitomycin or high-temperature treatment resulted in the production of bacteriocins and phages in both phases of Xenorhabdus nematophilus A24, indicating lysogeny. Phage DNA purified from X. nematophilus A24 hybridized to several fragments of DraI-digested A24 chromosomal DNA, confirming that the phage genome was incorporated into the bacterial chromosome. Bacteriocins and phages we...
متن کاملPhase Variation in Xenorhabdus nematophilus and Photorhabdus luminescens: Differences in Respiratory Activity and Membrane Energization.
Phase variation in Xenorhabdus and Photorhabdus spp. has a significant impact on their symbiotic relationship with entomopathogenic nematodes by altering the metabolic by-products upon which the nematodes feed. The preferential retention of the phase I variant by the infective-stage nematode and its better support for nematode reproduction than phase II indicates its importance in the bacterial...
متن کاملThe Xenorhabdus nematophila nilABC genes confer the ability of Xenorhabdus spp. to colonize Steinernema carpocapsae nematodes.
Members of the Steinernema genus of nematodes are colonized mutualistically by members of the Xenorhabdus genus of bacteria. In nature, Steinernema carpocapsae nematodes are always found in association with Xenorhabdus nematophila bacteria. Thus, this interaction, like many microbe-host associations, appears to be species specific. X. nematophila requires the nilA, nilB, and nilC genes to colon...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
