Effects of Common Mycorrhizal Networks and Arbuscular Mycorrhizal Fungi on Ascochyta Blight in Chickpea

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Cicer arietinum L. (chickpea) is susceptible to Ascochyta blight (AB). Arbuscular mycorrhizal fungi (AMF) are symbiotic root colonizing fungi that exchange soil nutrients for photosynthetic carbon. AMF form common mycorrhizal networks (CMNs), connecting plant roots and transferring nutrients.

Exploration of Ascochyta rabiei diversity through various molecular tools and control of its pathogenic strain via green synthesized zinc oxide nanoparticles

Results in Chemistry
Fungus is the most important disease-causing biotic factor on earth. The study of their genetic diversity is very important for their management and control.

Deciphering the biosynthetic pathways of lichen acids

New Phytologist, Volume 250, Issue 3, Page 1784-1799, May 2026.
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Physiological studies on Ascochyta rabiei (Pass.) Lab. [PDF]

, 2022
The effect of culture media, carbon and nitrogen sources, pH levels and temperature were studied on mycelial growth of Ascochyta rabiei. Maximum growth of the fungus was found on chickpea extract agar medium.

Baseline Sensitivity of Ascochyta rabiei to Azoxystrobin, Pyraclostrobin, and Boscalid [PDF]

Plant Disease, 2008
Ascochyta rabiei, causal agent of Ascochyta blight on chickpea (Cicer arietinum), can cause severe yield loss in the United States. Growers rely on applications of fungicides with site-specific modes of action such as the quinone outside inhibiting (QoI) fungicides azoxystrobin and pyraclostrobin, and the carboximide fungicide boscalid, to manage ...

Molecular Detection of Exserohilum turcicum in Maize Seeds: Validation of Specific Primers and Development of PCR/qPCR Protocols

Journal of Phytopathology, Volume 174, Issue 2, March/April 2026.
ABSTRACT Northern corn leaf blight, one of the most devastating diseases of maize (Zea mays), is caused by Exserohilum turcicum. This pathogen is widely distributed and can be found in maize fields across most regions of the world. The association of pathogens with seeds is considered a serious threat to the establishment of a field since seeds are ...

Defence gene expression profiling to Ascochyta rabiei aggressiveness in chickpea [PDF]

Theoretical and Applied Genetics, 2016
Significant differences in defence pathway-related gene expression were observed among chickpea cultivars following A. rabiei infection. Differential gene expression is indicative of diverse resistances, a theoretical tool for selective breeding. A high number of Ascochyta rabiei pathotypes infecting chickpea in Australia has severely hampered efforts ...

Breeding for quantitative disease resistance: Case studies, emerging approaches, and exploiting pathogen variation

Crop Science, Volume 65, Issue 6, November/December 2025.
Abstract Host resistance, using qualitative genes with major effects, such as resistance (R) genes, is one of the most effective disease control strategies. However, because major gene‐derived resistance wanes over time, breeders must increasingly focus on quantitative trait loci and minor effect genes, which, when pyramided together, can confer ...

Genetic diversity of microsatellite alleles located at quantitative resistance loci for Ascochyta blight resistance in a global collection of chickpea germplasm

Phytopathologia Mediterranea, 2013
A global collection of 43 chickpea (Cicer arietinum L.) genotypes, resistant and susceptible to Ascochyta blight caused by Ascochyta rabiei was evaluated for the disease under controlled conditions.
