Antifungal potential of Azotobacter species and its metabolites against Fusarium verticillioides and biodegradation of fumonisin.

Aims: In the study, seven Plant Growth Promoting Rhizobacteria (PGPR) Azotobacter species were screened against three strains of Fusarium verticillioides to test its antifungal activity. Azotobacter strains were tested for the degradation of fumonisin produced by F. verticillioides.

Antifungal Potential of Strain 31 against Phytopathogenic spp. Associated with Cereals.

Antifungal efficacy of against trichothecene-producing spp. was investigated in maize, sorghum, and wheat. The three cereals were subjected to four treatments as control (T1), alone (T2), combination of and treatment (T3), and only (T4).

Spatial distribution and identification of potential risk regions to rice blast disease in different rice ecosystems of Karnataka.

Rice is a globally important crop and highly vulnerable to rice blast disease (RBD). We studied the spatial distribution of RBD by considering the 2-year exploratory data from 120 sampling sites over varied rice ecosystems of Karnataka, India. Point pattern and surface interpolation analyses were performed to identify the spatial distribution of RBD.

Multilocus sequence analysis and identification of mating-type idiomorphs distribution in Magnaporthe oryzae population of Karnataka state of India.

Aims: To investigate the genetic diversity, population structure and mating-type distribution among the eco-distinct isolates of Magnaporthe oryzae from Karnataka, India.

Methods And Results: A set of 38 isolates of M. oryzae associated with leaf blast disease of rice were collected from different rice ecosystems of Karnataka, India, and analysed for their diversity at actin, β-tubulin, calmodulin, translation elongation factor 1-α (TEF-1-α), and internal transcribed spacer (ITS) genes/region.

Morpho-molecular diversity and avirulence genes distribution among the diverse isolates of Magnaporthe oryzae from Southern India.

Aims: To investigate the diversity of eco-distinct isolates of Magnaporthe oryzae for their morphological, virulence and molecular diversity and relative distribution of five Avr genes.

Methods And Results: Fifty-two M. oryzae isolates were collected from different rice ecosystems of southern India.

Antifungal activity of against trichothecene-producing species associated with cereals.

Antifungal efficacy of on infection, total seedlings mass, root and shoot length, and seed germination in maize, sorghum, and wheat were investigated. Antifungal efficacy of against , , and showed a significant reduction in growth and infection incidence (up to 50%) in all the three treated cereals. However, challenge inoculation of spp.

Sexuality generates diversity in the aflatoxin gene cluster: evidence on a global scale.

Aflatoxins are produced by Aspergillus flavus and A. parasiticus in oil-rich seed and grain crops and are a serious problem in agriculture, with aflatoxin B₁ being the most carcinogenic natural compound known. Sexual reproduction in these species occurs between individuals belonging to different vegetative compatibility groups (VCGs).
