Genes That Control Nematode Parasitism of Plants
The most evolutionary advanced adaptations for plant parasitism by nematodes are the products of parasitism genes expressed in their esophageal gland cells and secreted through their stylet into host tissue to control the complex process of parasitism. Molecular analyses of nematode parasitism genes are revealing the complexity of the tools that enable the nematode to attack plants, and the res...
متن کاملSympatric speciation through intraspecific social parasitism.
Sympatric speciation through intraspecific social parasitism has been proposed for the evolution of Hymenopteran workerless parasites. Such inquilines exploit related host taxa to produce their own sexual offspring. The relatedness of inquilines to their hosts has been generalized in Emery's rule, suggesting that social parasites are close or the closest relatives to their host species. If the ...
متن کاملRoot-knot and cyst nematode parasitism genes: the molecular basis of plant parasitism.
Roundworms of the Nematoda comprise one of the largest animal phyla on Earth (1). They inhabit diverse terrestrial and aquatic niches through adaptations of a spectrum of trophic groups, including parasites that threaten human, animal and crop plant health. The most well-known nematode, Caenorhabditis elegans, is a native soil-dwelling microbivore that has emerged as a premier model for animal ...
متن کاملPlastid genes that were lost along the road to parasitism.
Some plants rely on others to do their photosynthesis for them. For example, most plants in thebroomrape family (Orobanchaceae; see figure) are parasitic, meaning they rely on a host plant for inorganic and organic nutrients as well as water. In most land plants, the selective pressure on photosynthesis-related elements causes plastid chromosomes to be conserved in terms of structure, gene cont...
