reproduction of the white tip nematode (aphelenchoides besseyi christie, 1942) in different monoxenic cultures
the reproductive range of the iranian population of white tip nematode in rice, aphel-enchoides besseyi, was investigated in vitro to find out a suitable medium as well as a fa-vorable fungal host for monoxenic culturing this nematode. studies were carried out on rice seed associated fungi, pathogenic fungi and one mushroom (agaricus bisporus) grown on three culture media, rpa (rice polish agar...
متن کاملTranscriptomic Analysis of the Rice White Tip Nematode, Aphelenchoides besseyi (Nematoda: Aphelenchoididae)
BACKGROUND The rice white tip nematode Aphelenchoides besseyi, a devastating nematode whose genome has not been sequenced, is distributed widely throughout almost all the rice-growing regions of the world. The aims of the present study were to define the transcriptome of A. besseyi and to identify parasite-related, mortality-related or host resistance-overcoming genes in this nematode. METHOD...
متن کاملObservations on the Foliar Nematode, Aphelenchoides besseyi, Infecting Tuberose and Rice in India.
The foliar nematode Aphelenchoides besseyi causes white tip disease in rice (Oryza sativa L.) and floral malady in tuberose (Polianthes tuberosa L.). This nematode is widely distributed in the rice fields of many states of India, including West Bengal (WB), Andhra Pradesh (AP), Madhya Pradesh (MP) and Gujarat (GT). In order to generate information on intraspecific variations of A. besseyi as we...
متن کاملEarly Embryogenesis and Anterior-Posterior Axis Formation in the White-Tip Nematode Aphelenchoides besseyi (Nematoda: Aphelenchoididae).
We followed the early embryogenesis of Aphelenchoides besseyi from fertilization to the 4-cell stage under Nomarski optics and examined the chromosome number and structure by DAPI staining. After an oocyte is fertilized by a sperm, the eggshell forms and the male and female pronuclei are reconstructed. The male pronucleus moves toward the female pronucleus, which is located at the center of the...
متن کاملTrehalose metabolism genes render rice white tip nematode Aphelenchoides besseyi (Nematoda: Aphelenchoididae) resistant to an anaerobic environment.
After experiencing anaerobic environments, Aphelenchoides besseyi will enter a state of suspended animation known as anoxybiosis, during which it may use trehalose as an energy supply to survive. To explore the function of trehalose metabolism, two trehalose-6-phosphate synthase (TPS) genes (Ab-tps1 and Ab-tps2) encoding enzymes catalysing trehalose synthesis, and three trehalase (TRE) genes (A...
