Three-dimensional reconstruction of the stomatostylet and anterior epidermis in the nematode Aphelenchus avenae (Nematoda: Aphelenchidae) with implications for the evolution of plant parasitism.
A three-dimensional model of the stomatostylet and associated structures has been reconstructed from serial thin sections of Aphelenchus avenae, a representative of Tylenchomorpha, a group including most plant parasitic nematodes. The reconstruction is compared with previous work on bacteriovorous cephalobids and rhabditids to better understand the evolution of the stylet and its associated cel...
متن کاملComparative, three-dimensional anterior sensory reconstruction of Aphelenchus avenae (nematoda: Tylenchomorpha).
The anterior sensory anatomy (not including amphids) of the nematode Aphelenchus avenae (Tylenchomorpha) has been three-dimensionally reconstructed from serial, transmission electron microscopy thin sections. Models, showing detailed morphology and spatial relationships of cuticular sensilla and internal sensory receptors, are the first computerized reconstruction of sensory structures of a Tyl...
متن کاملGametogenesis in amphimictic and parthenogenetic populations of Aphelenchus avenae.
The female reproductive system of Aphelenchus avenae, studied in orcein-stained material, showed a peculiar structural pattern not yet reported in other nematodes. Chromosome morphology and behavior during gametogenesis could be studied in more detail than in other tylenchid or aphelenchid species investigated to date. In a bisexual population from Australia, gametogenesis was by normal meiosis...
متن کاملInhibition of Acetylcholinesterases from Aphelenchus avenae by Carbofuran and Fenamiphos.
Exposure to carbofuran and fenamiphos for 72 hours reduced the numbers of active Aphelenchus avenae in aqueous suspension by > 75%. When nematicides were removed, many A. avenae exposed to carbofuran resumed normal movement but A. avenae treated with fenamiphos did not recover. Acetylcholinesterase (AChE) activity was suppressed by > 95% in nematodes treated with carbofuran or fenamiphos. Howev...
متن کاملMorpho-physiological Characteristics of Brassica napus L. Under Cadmium Stress
Cadmium as a heavy metal is also considered as a serious threat for the environment. This element is accumulated in soil through industrial processes as well as phosphate fertilizers and aggregates into the food chain. This study was conducted in order to investigate the different levels of cadmium effects on growth features of rapeseed (Brassica napus L.) plants. Root and shoot weight and heig...
