Er gloort hoop voor door schimmels geplaagde bananentelers. Wageningse onderzoekers hebben ontdekt dat een eiwit dat tomatenplanten resistent maakt tegen bladvlekkenziekte, mogelijk ook de banaan kan wapenen tegen de zwarte Sigatokaschimmel. Dat schrijven ze in PNAS (online op 5 april). Voor het
We developed an efficient method for DNA extraction from Cladosporioid fungi, which are important fungal plant pathogens. The cell wall of Cladosporioid fungi is often melanized, which makes it difficult to extract DNA from their cells. In order to overcome this we grew these fungi for three days on
The Arabidopsis (Arabidopsis thaliana) CLAVATA2 (CLV2) gene encodes a leucine-rich repeat receptor-like protein (RLP) that is involved in controlling the stem cell population size in the shoot apical meristem. Our previous genome-wide functional analysis of 57 AtRLP genes revealed only a few phenoty
It is accepted that most fungal avirulence genes encode virulence factors that are called effectors. Most fungal effectors are secreted, cysteine-rich proteins, and a role in virulence has been shown for a few of them, including Avr2 and Avr4 of Cladosporium fulvum, which inhibit plant cysteine prot
The pioneering research of Harold Flor on flax and the flax rust fungus culminated in his gene-for-gene hypothesis. It took nearly 50 years before the first fungal avirulence (Avr) gene in support of his hypothesis was cloned. Initially, fungal Avr genes were identified by reverse genetics and map-b
Plant activation of host defense against pathogenic microbes requires significant host transcriptional reprogramming. In this study, we compared transcriptional changes in tomato during compatible and incompatible interactions with the foliar fungal pathogen Cladosporium fulvum and the vascular fung
