Fig. 2From: Transcriptomic comparison between two Vitis vinifera L. varieties (Trincadeira and Touriga Nacional) in abiotic stress conditionsPrincipal Component Analysis (PCA) of microarray results in growth room and field experiments. The PCA were performed with normalized expression of all the transcripts. a Trincadeira (TR) growth room; b Touriga Nacional (TN) growth room; c Field experiment with both varieties; −C, growth room control; −H, growth room heat stress; −L, growth room high light radiation stress; −W, growth room water deficit. FTN-C, Field full irrigation Touriga Nacional, control; FTN-S, Field non-irrigation Touriga Nacional, stress; FTR-C, Field full irrigation Trincadeira, control; FTR-S, Field non-irrigation Trincadeira, stressBack to article page
