Pest Management Science, 2023 For the first time, this study provides evidence that the timing of co‐inoculation influences the outcome of competition between Leptosphaeria maculans and Leptosphaeria biglobosa; L. biglobosa can inhibit sirodesmin PL production and the growth of L. maculans if it is inoculated before L. maculans or less than 3 days after L. maculans.

The Effect of Trichoderma harzianum Hypovirus 1 (ThHV1) and Its Defective RNA ThHV1-S on the Antifungal Activity and Metabolome of Trichoderma koningiopsis T-51 [PDF]
Journal of Fungi, 2023 Mycoviruses widely exist in filamentous fungi and sometimes cause phenotypic changes in hosts. Trichoderma harzianum hypovirus 1 (ThHV1) and its defective RNA ThHV1-S were found in T. harzianum and exhibited high transmissibility.

Molecular characterization of a polymycovirus in Leptosphaeria biglobosa. [PDF]
Arch VirolAbstract Leptosphaeria biglobosa is a phytopathogenic ascomycete of Brassica napus that causes phoma stem canker/blackleg. A new double-stranded RNA (dsRNA) mycovirus from this fungus has been fully characterized. The virus genome has five dsRNA segments, ranging in length from 1,180 bp to 2,402 bp.

A New Subclade of Leptosphaeria biglobosa Identified from Brassica rapa. [PDF]
Int J Mol Sci, 2019 Blackleg (Phoma stem canker) of crucifers is a globally important disease caused by the ascomycete species complex comprising of Leptosphaeria maculans and Leptosphaeria biglobosa. Six blackleg isolates recovered from Brassica rapa cv. Mizspoona in the Willamette Valley of Oregon were characterized as L.

LAMP Detection and Identification of the Blackleg Pathogen Leptosphaeria biglobosa ‘brassicae’ [PDF]
Plant Disease, 2021 Blackleg of oilseed rape is a damaging invasive disease caused by the species complex Leptosphaeria maculans (Lm)/L. biglobosa (Lb), which is composed of at least two and seven phylogenetic subclades, respectively. Generally, Lm is more virulent than Lb, but under certain conditions, Lb can cause a significant yield loss in oilseed rape. Lb ‘brassicae’

Transposable element-assisted evolution and adaptation to host plant within the Leptosphaeria maculans-Leptosphaeria biglobosa species complex of fungal pathogens. [PDF]
BMC Genomics, 2014 Many plant-pathogenic fungi have a tendency towards genome size expansion, mostly driven by increasing content of transposable elements (TEs). Through comparative and evolutionary genomics, five members of the Leptosphaeria maculans-Leptosphaeria biglobosa species complex (class Dothideomycetes, order Pleosporales), having different host ranges and ...
