Transcriptome analysis of germinating maize kernels exposed to smoke-water and the active compound KAR1.

ABSTRACT:

Background

Smoke released from burning vegetation functions as an important environmental signal promoting the germination of many plant species following a fire. It not only promotes the germination of species from fire-prone habitats, but several species from non-fire-prone areas also respond, including some crops. The germination stimulatory activity can largely be attributed to the presence of a highly active butenolide compound, 3-methyl-2H-furo[2,3-c]pyran-2-one (referred to as karrikin 1 or KAR1), that has previously been isolated from plant-derived smoke. Several hypotheses have arisen regarding the molecular background of smoke and KAR1 action.

Results

In this paper we demonstrate that although smoke-water and KAR1 treatment of maize kernels result in a similar phys
