Monographella albescens is a fungal plant pathogen[1] also known as leaf scald[1] which infects rice.[1]
Transmission
Conidia are transferred by water splash.[2]
Host resistance
Lines of rice that are resistant against M. albescens are available.[2] Most resistance breeding has been in field trials in countries where the disease is already widespread.[2] Even in "resistant" strains, however, there is some noticeable lesioning but little to no loss of yield.[2] The mechanism of resistance remains unknown.[2] There is wide variation in pathogen strain-host strain pathogenicity.[2]
Rice plants fed increased silicon showed increased resistance to M. albescens.[1] Surprisingly this is not - or not entirely - due to its structural role but also due to increased production of various compounds and enzymes.[1]
