Organic acids can stimulate the formation of a ROL barrier
The barrier to radial oxygen loss (ROL) from roots enable roots in waterlogged soils to penetrate deeper into the soil before they run out of oxygen in the apical root meristem. The signalling pathway is not known, i.e. what are the environmental signals that results in a ROL barrier formation. This project aims at testing the effect of low concentrations of organic acids and their role barrier formation. The project is funded by a UWA Research Collaboration Award to Prof Colmer, Prof Nakazono and myself.
Root of rice can form a barrier to radial oxygen loss when growing in anoxic soils. We are currently trying to reveal the signalling that initiates the barrier formation using rice which has been exposed to various concentrations of organic acids in the root medium.
