بررسی سیستم ناسازگاری جنسی در جدایه های ایرانی Tilletia indica

Surface rodlets of Tilletia indica teliospores.

Tilletia indica teliospores were studied by use of thin sections and freeze-etch replicas. Surfaces of these spores have rodlet patterns which differ from those previously reported for spores of other fungi. The rodlets on T. indica teliospores average 240 nm in length and are not grouped into fascicles.

An Allee Effect Reduces the Invasive Potential of Tilletia indica.

ABSTRACT The Karnal bunt pathogen, Tilletia indica, is heterothallic and depends on encounters on wheat spikes between airborne secondary sporidia of different mating types for successful infection and reproduction. This life history characteristic results in reduced reproductive success for lower population densities. Such destabilizing density dependence at low population levels has been desc...

Susceptibility of Wheat to Tilletia indica During Stages of Spike Development.

ABSTRACT Karnal bunt of wheat is caused by the fungus Tilletia indica, which partially converts kernels into sori filled with teliospores. Despite minor overall yield and quality losses, the disease is of considerable international quarantine concern. Plant development stages reported susceptible to infection vary considerably. A study was designed to better define the susceptibility period by ...

Comparative analysis of RAPD and ISSR marker assays for detecting genetic polymorphism in Tilletia indica

Karnal bunt of wheat, caused by Tilletia indica Mitra is an important disease prevalent in several countries. The pathogen due to its heterothallic nature shows high variability. In the present study, genetic relationships among ten isolates of T.indica collected from different locations of India and 15 monosporidial lines raised from these isolates were investigated by using 34 RAPD and 28 ISS...
