Dwarf bunt of wheat, caused by Tilletia controversa Kühn (TCK), is a destructive disease on wheat, as well as an important international quarantine disease. The traditional methods for diagnosis and detection of the disease were mostly based on the morphological characteristics, germination test of teliospores, and the symptom of disease in the field, resulting in a long procedure and low accur...

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...

To investigate the lignifications process and its physiological significance under Karnal Bunt (KB), the changes in enzymes responsible for lignifications likes, phenylalanine ammonia lyase (PAL), were determined in resistant (HD-29) and susceptible genotype (WH-542) of wheat during different developmental stages. The PAL gene was cloned and sequenced. The expression of PAL gene was measured by...

Tilletia indica causes the disease Karnal bunt in wheat. The disease is under international quarantine regulations. Comparative mitochondrial (mt) genome analysis of T. indica (KX394364 and DQ993184) and T. walkeri (EF536375) has found 325 to 328 SNPs, 57 to 60 short InDels (from 1 to 13 nt), two InDels (30 and 61 nt) and five (>200 nt) presence/absence variations (PAVs) between the two species...

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...

Karnal bunt disease in wheat is caused by hemibiotrophic fungus, Tilletia indica that has been placed as quarantine pest in more than 70 countries. Despite its economic importance, little knowledge about the molecular components of fungal pathogenesis is known. In this study, first time the genome sequence of T. indica has been deciphered for unraveling the effectors' functions of molecular pat...
