Boron (B) is an essential nutrient for plants but is toxic at high levels. We performed transcriptome analysis under conditions of both low and high B in <i>Arabidopsis thaliana</i>. There is a positive correlation between the levels of gene induction by low and high B, suggesting that common pathways operate during these responses. Induction by high B was also confirmed for nine genes in an independent experiment. Transcripts of <i>At1g03770</i> (transcription factor) and <i>At5g57340</i> were found to be elevated in roots, whereas <i>At2g04040</i>, <i>At2g04050</i>, <i>At2g04070</i> (all encoding multidrug and toxic compound extrusion transporters), <i>At1g32870</i> (transcription factor), <i>At5g51440</i> (heat shock protein-like), <i>At2g41730</i> and <i>At2g21640</i> are induced in the shoots. The accumulation of both <i>At2g04050</i> and <i>At5g51440</i> transcripts was further found to be elevated by more than 100-fold after two days of high B treatment. Our findings thus represent the first identification of high B-induced genes.
