Seminars

Barrier tissues isolate organisms from their surrounding environment and maintaining the tissue’s integrity is essential for this function. In many seed plants, periderm forms as the outer barrier in mature roots and stems to prevent water loss and pathogen infection. The periderm is regenerated when it gets injured; however, the underlying mechanism remains largely unknown, despite its importance for plant survival. In this seminar, I will discuss that periderm integrity in Arabidopsis roots is sensed by diffusion of the gases, ethylene and oxygen.
