Transcription profiling of Arabidopsis thaliana root parts in reaction to fungal (Laccaria bicolor) volatiles

Arabidopsis thaliana plants were grown from seeds in Petri dishes on MS medium. 4 days old plants were co-incubated with L. bicolor without physical contact. After 2 days of co-incubation, roots were either harvested whole or separated into the root tip (ca. 1/4 of the whole root) and the lateral root zone (= remaining root).
