Transcription profiling of barley leaves after boron reveals a late response to boron toxicity

ABSTRACT: Barley1 GeneChip was used to investigate transcriptome changes associated with boron (B) toxicity in a sensitive barley cultivar (Hordeum vulgare L. cv. Hamidiye). Eight day old aseptically grown seedlings were subjected to 5 or 10 mM boric acid (B(OH)3) treatments for 5 days and expression profiles were determined with DNA microarrays using total RNA from leaf tissues. Surface sterilized seeds were aseptically germinated and grown on half strength Hoagland’s solution (Hoagland and Arnon, 1950) (pH 5.8) solidified with Phytagel® for 8 days at 23±2ºC with 16 h light (400 µmol m–2 s–1) and 8 h dark photo-cycle with 70% relative humidity. Seedlings were transferred to sterile hydroponic cultures for B treatment, which was applied immediately after transfer as half strength Hoaglandâ
