The increasing evidence for a role of developmental plasticity in evolution offers exciting prospects for testing interactions between ecological and developmental genetic processes. Recent advances with the model organism Pristionchus pacificus have provided inroads to a mechanistic understanding of a developmental plasticity. The developmental plasticity(More)
Sourdough is the foremost cereal fermentation performed in a variety of technologies with almost any cereal. The lactobacilli studied most intensely include Lactobacillus sanfranciscensis, L. reuteri and L. pontis isolated from traditional and modern rye and wheat fermentations. Molecular biology tools are available for their rapid identification and(More)
Within the framework of the characterization of the microflora of an industrial sourdough fermentation, strains of Lactobacillus amylovorus, Lactobacillus pontis and two other strains were isolated which could not be associated with a valid species. These latter strains were Gram-positive, catalase-negative, non-spore-forming, non-motile rods that could be(More)
Developmental plasticity has been suggested to facilitate phenotypic diversity, but the molecular mechanisms underlying this relationship are little understood. We analyzed a feeding dimorphism in Pristionchus nematodes whereby one of two alternative adult mouth forms is executed after an irreversible developmental decision. By integrating developmental(More)
A specific multiplex PCR assay based on the amplification of parts of the 16S rRNA molecule was designed. Primers derived from variable regions of the 16S rRNA provided a means of easily differentiating the species Lactobacillus pontis and Lactobacillus panis. They could be clearly discriminated from the phylogenetically related species Lactobacillus(More)
