Resistance of rice cultivars to white tip disease caused by Aphelenchoides
Aphelenchoides besseyi is a seed-borne plant parasitic nematode and is widely distributed in most rice growing areas. Application of resistant cultivars requires the identification of resistance source, which can then be included in breeding programs to improve the local rice cultivars. Fourteen Iranian rice genotypes including improved and local varieties were evaluated for resistance to A. be...
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 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...

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...
