Mold and mildew can develop in both indoor and outdoor gardens but tends to be more devastating indoors, and can wipe out an entire crop if it is not controlled. Ultraviolet (UV) light can be used to eradicate mold spores that accumulate on floors or that spread via air currents. The primary mold spore of concern is usually Botrytis cinerea, a ubiquitous fungi that often contaminates soil and i...

Powdery mildew of sugar beet, a disease of major economic significance, was first described at the beginning of the 20th century, and since then there has been some confusion over the correct taxonomic identity of the causal agent. In Europe, the fungus was initially classified as the novel species Microsphaera betae, later re-named Erysiphe betae, whilst in America it was identified as E. poly...

Pathogenesis-related proteins (PRs) can lead to increased resistance of the whole plant to pathogen attack. Here, we isolate and characterize a PR-4 protein (VpPR4-1) from a wild Chinese grape Vitis pseudoreticulata which shows greatly elevated transcription following powdery mildew infection. Its expression profiles under a number of abiotic stresses were also investigated. Powdery mildew, sal...

Sulla is a biannual forage legume cultivated throughout the Mediterranean Basin. It can be severely damaged by powdery mildew, but there little understanding on its causal species or host range. The taxonomic characterization of Erysiphe mainly based examination chasmothecia morphology, molecular analysis ITS1 and ITS2 sequences. However, description morphology ITS sequences not always availabl...
