Intravascular Large B-Cell Lymphoma.

Context.—: Intravascular large B-cell lymphoma (IVLBCL) is a rare hematopathologic entity, posing both a clinical and histologic challenge for diagnosis. Numerous pitfalls can hinder making the diagnosis.

A high throughput targeted gene disruption method for Alternaria brassicicola functional genomics using linear minimal element (LME) constructs.

Alternaria brassicicola causes black spot disease of cultivated Brassicas and has been used consistently as a necrotrophic fungal pathogen for studies with Arabidopsis. In A. brassicicola, mutant generation has been the most rate-limiting step for the functional analysis of individual genes due to low efficiency of both transformation and targeted integration.
