Genetic diversity and population structure of Fusarium udum in India and its correlation with pigeonpea wilt incidence
In a study conducted in India, 50 Fusarium isolates were collected from pigeonpea growing regions and extensively examined for their cultural and morphological characteristics. These isolates exhibited significant variations in traits including growth rate, mycelial growth patterns, color, zonation, pigmentation, spore size, and septation. Subsequently, 30 isolates were chosen for pathogenicity testing on eight pigeonpea genotypes. Results showed distinct reactions, with four genotypes displaying differential responses (ICP8858, ICP8859, ICP8862, and BDN-2), while ICP9174 and ICP8863 consistently exhibited resistance and ICP2376 and BAHAR remained susceptible to wilt disease. To study the interaction between Fusarium isolates and pigeonpea host differentials (HDs), an additive main effects and multiplicative interaction analysis was conducted. The majority of disease incidence variation (75.54%) was attributed to HD effects, while Fusarium isolate effects accounted for only 1.99%. The interaction between Isolates and HDs (I × HD) contributed 21.95% to the total variation, being smaller than HD but larger than I. Based on HD reactions, isolates were classified into nine variants, showing varying distributions across pigeonpea growing states, with variants 2 and 3 being prevalent in several regions. This diversity underscores the need for location-specific wilt-resistant pigeonpea cultivars. Furthermore, genetic analysis of 23 representative isolates, through internal transcribed spacer region of ribosomal DNA and translation elongation factor 1-α gene sequencing, revealed three major clusters: Fusarium udum, Fusarium solani, and Fusarium equiseti. These findings hold potential for developing location-specific wilt-resistant pigeonpea cultivars and enhancing disease management strategies.
期刊介绍:
The Journal of Basic Microbiology (JBM) publishes primary research papers on both procaryotic and eucaryotic microorganisms, including bacteria, archaea, fungi, algae, protozoans, phages, viruses, viroids and prions.
Papers published deal with:
microbial interactions (pathogenic, mutualistic, environmental),
ecology,
physiology,
genetics and cell biology/development,
new methodologies, i.e., new imaging technologies (e.g. video-fluorescence microscopy, modern TEM applications)
novel molecular biology methods (e.g. PCR-based gene targeting or cassettes for cloning of GFP constructs).
