Fig. 4From: High-throughput gene-expression quantification of grapevine defense responses in the field using microfluidic dynamic arraysCorrelation scatter plots of fold expression of “BioMolChem” chip genes (n = 24) using Stratagene or Biomark HD systems obtained with three replicates of leaves treated with BTH (red), with FOS (green) or untreated (black). Correlation of fold expression obtained by Stratagene MX3005P system (x axis) and microfluidic dynamic array (y axis). R 2 = coefficient of correlation of the simple linear regression, PPMCC = Pearson product–moment correlation coefficient (Pearson’s correlation). Significant correlation was determined at a level of p-value < 0.05Back to article page
