Microarray analysis of the mvp-mutant and the wild-type seedlings. (a) Volcano plots illustrating the log₂ fold changes in gene expression differences between mvp mutants and wild-type plants. Probesets with statistically different expression (P≤0.05) and fold changes of ≥2-fold (263) are shown in the upper right corner and probesets with ≤–2-fold (105) are shown in the upper left corner. (b) Differentially regulated genes in mvp-mutant plants compared with wild-type plants derived from the microarray analysis: The differentially regulated genes were subdivided into six classes: Biotic-stress related genes (1), transcription factors (2), sugar metabolism (3), oxidative stress (4), miscellaneous genes (5), and unknown genes (6). The same RNA samples used in Fig. 1 were used for microarrays.
