Abstract
We examined the transcripts that showed changes among the ca.7000 Arabidopsis full-length cDNAs under biotic and abiotic stresses. The expression of 894 and 1554 genes was induced under biotic and abiotic stresses, respectively. Furthermore, the transctript levels of 541 genes commonly increased in Arabidopsis plants treated with biotic and abiotic stresses. After inoculation with A. alternata, A. brassicicola and C. higginsianum to induce a biotic stress, the transcript levels of 118, 858 and 142 genes increased in Arabidopsis plants, respectively. By contrast, the expression of 740, 438, 605, 290 and 672 genes was induced by dehydration, cold, high-salinity, UV-C and CuSO4 treatments for abiotic stress. We also examined the transcripts that showed changes among the ca.7000 Arabidopsis full-length cDNAs under ABA, SA, JA, ET (ethephon), paraquat and rose bengal-treatments. The results show that full-length cDNA microarray analysis is a powerful tool for identifying multiple stress-responsive genes.
