Stress-Responsive Expression of UGT Genes in Arabidopsis Leaves and Seedlings Based on Affymetrix ATH1 Microarray Data.

The distribution of maximal inductions to abiotic and biotic stress factors among all UGT members is shown. Significant inductions equal or higher than twofold (dark gray) and higher than 1.5-fold (light gray) are indicated. Genes are sorted from highest to lowest abiotic and biotic stress inducibility using mutual ranking (see Methods). The top stress-induced gene, UGT76B1, which was used for further analysis, is indicated with an arrow. A1, osmotic; A2, salt; A3, UV-B; A4, oxidative; A5, wounding; A6, drought; A7, cold; A8, heat; B1, P. syringae pv tomato DC3000 (virulent); B2, P. syringae pv phaseolicula (avirulent); B3, Phytophthora infestans; B4, Botrytis cinerea; B5, P. syringae pv maculicola ES4326 (virulent); B6, Erysiphe orontii.
