Quinoa (Chenopodium quinoa) is a seed crop of the Andean highlands and Araucanian coastal regions of South America that has recently expanded in use and production beyond its native range. This is largely due to its superb nutritional value, consisting of protein that is rich in essential amino acids along with vitamins and minerals. Quinoa also presents a remarkable degree of tolerance to sali...

A population of Arabidopsis thaliana growing locally in a suburb of Zürich called Weiningen was observed to be infected with downy mildew. Plants were collected and the progress of infection was investigated in artificial inoculations in the laboratory. The plants proved to be highly susceptible, and pronounced intercellular mycelial growth, haustoria formation, conidiophore production, and spo...

Polygalacturonase-inhibitor protein (PGIP) is a defense protein found in plant cell walls. It prevents the degradation of pectin by modulating the endo-polygalacturonase activity. The present study has used heterologous anti-bean PGIP probes to investigate the role of PGIP in pearl millet [Pennisetum glaucum (L) R. Br.] resistance against downy mildew caused by oomycete pathogen Sclerospora gra...

The diagnosis model of the cucumber diseases and insect pests was established by laser-induced chlorophyll fluorescence (LICF) spectroscopy technology combined with Back Propagation Artificial Neural Networks (BP-ANN) algorithm in this research. This model would be used to realize the fast and exact diagnosis of the cucumber diseases and insect pests. Four kinds of in-vivo cucumber leaves (heal...

The perception of downy mildew avirulence (Arabidopsis thaliana Recognized [ATR]) gene products by matching Arabidopsis thaliana resistance (Recognition of Peronospora parasitica [RPP]) gene products triggers localized cell death (a hypersensitive response) in the host plant, and this inhibits pathogen development. The oomycete pathogen, therefore, is under selection pressure to alter the form ...

Infection of cantaloupe plant with Downy mildew caused by the fungus Pseudoperonospora cubensis leads to significant losses in amount crop, addition to, reducing its marketing value many countries around world, therefore, efficacy each organisms (Trichoderma harzianum, Trichoderma viride, Bacillus subtilis, megaterium and Pseudomonas fluorescens), fungicid...
