Rust fungi are plant parasites that depend on living host tissue for growth. For invasion of leaves, dikaryotic urediospores differentiate germ tubes and infection structures that penetrate through stomata. Biotrophic growth occurs by intercellular mycelia that form haustoria within host cells. A cDNA library was constructed from haustoria isolated from broad bean leaves infected by Uromyces fa...

The powdery mildew fungi are obligate biotrophic plant pathogens that develop a specialized structure for parasitism termed haustorium, which is responsible for nutrient uptake and factor exchange with the plant. In this work, we present a detailed microscopy analysis of the haustoria of the cucurbit powdery mildew fungus Podosphaera xanthii, a major limiting factor for cucurbit production worl...

Biotrophic pathogens are believed to strategically manipulate sugar transport in host cells enhance their access carbohydrates. However, mechanisms of translocation from biotrophic fungi such as powdery mildew across the plant–haustorium interface remain poorly understood. To investigate this question, systematic subcellular localisation analysis was performed for all 14 members monosaccharide ...

Salak palms (Salacca spp.) are important fruit species in Southeast Asia, but the morphogenesis of their reproductive organs is unknown. To observe female gametogenesis, pistil S. wallichiana and subsequent fertilization were observed. The ovary contained three ovule primordia months before flowering (BF). one mono-nucleate megaspore at center degenerated megaspores on chalazal side two BF, a e...
