What is it about?
Plants, as sessile organisms, are continually exposed to pathogen invasion attempts. Plants rely on an innate immune system that depends on efficient pathogen sensing and the rapid establishment of defense responses. We have shown that a well‐known class of elicitors of immunity, represented by the oligogalacturonides (OGs), i.e. pectin‐derived oligosaccharides released from plant cell walls upon partial degradation of homogalacturonan, are sensed and transduced by multiple and redundant perception complexes.

Why is it important?
Our observations reveal a complexity in the OG signaling pathways that is unique among the so far characterized elicitors of immunity in plants.
Perspectives
I think that this paper, through the identification of distinct subsets of OG responses, provides specific markers and may help to elucidate the complexity of innate immunity activation in plants.
