Field Evaluation of Tuberose Cultivars and Symptom Manifestation Caused by Foliar Nematode, Aphelenchoides besseyi in Tuberose

Observations 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...

Two Cases of Tuberose Sclerosis

The Nature of the Tuberose Fleshy Mole

Early 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...

Transcriptomic 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...
