Description regina (germplasm name); po: 0009005 root, (Organism Part); PO:0007520 root development stages (Development Stage); sand (Growth Media).
Four day old barley cv. Regina roots inoculated were inoculated with a zoospore suspension of 1 x 10 6 spores mL-1 P. graminis in buffer (0.1 g L-1 Phostrogen, 0.5% Bovine serum albumen). Sample prepared for roots collected from ten seedlings from each of the ten time points (15’, 30’, 45’ 1h, 2h, 3h, 4h, 5h, 6h, 7h) were combined for each treatment to give a time course pool. RNA was extracted from this time course pool and used for subsequent experiments.
Data processing The MAS5.0 Normalization is performed using the justMAS function in the simpleaffy package of Bioconductor ( The target value is 500 for all cases. The code was developed using R2.4.1, Bioconductor 1.9, and simpleaffy 2.8.0. The CDF files were downloaded from the Bioconductor website at The normalization scripts are available from the PLEXdb team by request.
