The plant cell wall has many significant structural and physiological roles, but the contributions of the various components to these roles remain unclear. Modification of cell wall properties can affect key agronomic traits such as disease resistance and plant growth. The plant cell wall is composed of diverse polysaccharides often decorated with methyl, acetyl, and feruloyl groups linked to t...

Allergic bronchopulmonary mycosis (ABPM) is a hypersensitivity-mediated disease of worldwide distribution. We reviewed 143 reported global cases of ABPM due to fungi other than aspergilli. The commonest etiologic agent was Candida albicans, reported in 60% of the cases, followed by Bipolaris species (13%), Schizophyllum commune (11%), Curvularia species (8%), Pseudallescheria boydii species com...

This is a case report of Bipolaris spicifera, a dematiaceous fungus commonly found in soil and as a plant pathogen, isolated from culture of the lesions and from an excisional biopsy specimen in a patient with diabetes and alcohol abuse. This case highlights the importance of considering Bipolaris as a differential diagnosis in patients with cutaneous lesions and the need for vigorous managemen...

Phaeohyphomycosis (PHM) is a term used to describe any fungus presenting in tissues with pseudohyphae, hyphae, brown yeast-like cells or a combination of these forms. Sinusitis and skin infections are the most common presentation of subcutaneous PHM caused by the fungus Bipolaris spicifera. However, the majority of cases have so far been encountered in tropical climatic zones. The present study...

A severe leaf spot, turning to foliage blight, was observed on leaves of Maranta leuconeura growing in a garden in Brazil (state of Rio de Janeiro) in 2015. A dematiaceous hyphomycete bearing a morphology typical of a helminthosporoid fungi was regularly found in association with diseased tissues. The fungus was isolated and pathogenicity was demonstrated through the completion of Koch's postul...

Rice brown spot (BS), caused by Bipolaris oryzae, is one of the major diseases of rice in Japan. Quantitative resistance has been observed in local cultivars (e.g., CH45), but no economically useful resistant variety has been bred. Using simple sequence repeat (SSR) polymorphic markers, we conducted quantitative trait locus (QTL) analysis of BS resistance in backcross inbred lines (BILs) from a...
