To help characterize the cellular mechanisms underlying the toxicity of Al to plants, we present the first large-scale, transcriptomic analysis of root responses to Al, using a microarray representing approximately 93% of the predicted genes in the genome of Arabidopsis. More transcripts were responsive to Al (25 μM) during long (48 h, 1,114 genes), as compared to short (6 h, 401 genes) exposures, which contrasts with previous microarray analyses of plant responses to other types of abiotic… CONTINUE READING
