We examined the transcripts that showed changes among the ca.7,000 Arabidopsis full-length cDNAs under biotic and abiotic stresses. Expression of Arabidopsis phospholipase A IIA (AtPLA IIA) gene was induced by various treatments such as pathogen inoculation (Alternaria alternata, Alternaria brassicicola and Colletotrichum higginsianum), cold, high-salinity, abscisic acid, salicylic acid, methyl jasmonate, ethephon, paraquat, rose bengal, UV-C and CuSO4-treatments. The regulation of AtPLA IIA gene expression under biotic and abiotic stresses was analyzed with AtPLA IIA promoter region (from +95 to –1,405) fused to the GUS reporter gene. In conclusion, the promoter activity is induced under these stresses.

Keywords: Keywords: Alternaria brassicicola — Arabidopsis thaliana — cDNA microarray — GUS activity — Reactive oxygen species.; Abbreviations: BTH, benzo[1,2,3]thiadiazole-7-carbothioic acid S-methyl ester; ET, ethephon; HR, hypersensitive response; JA, methyl jasmonate; ROS, reactive oxygen species; SA, salicylic acid.
