Increasing interest on the ecological significance of root grafts for forest populations.

Despite root grafts have been recognized in many tree species, they were for a long time regarded as a mere curiosity of nature, a random event related to tree proximity that had no evolutionary implications. Latter the discussion on the ecological role of root grafts developed into antagonistic interpretations: It is recognized to increase mechanical stability, but represents also an increased risk for pathogen transmission.

Could it be that a risk of disease transmission is the tradeoff upon the gain of mechanical stability and/or increased access to resources through the widened root system shared between grafted trees?.

We are very happy to learn that the interest on this topic is increasing and hope to bring more interesting findings during the incoming years.
