It has been 40 years since the first meeting dedicated to Frankia and actinorhizal plants, which was held at Petersham, Massachusetts (reported in Torrey and Tjepkema, 1979). Since then biennial meetings have been organised and held in different venues around the globe (Table 1). The most recent meeting, the "19th International Meeting on Frankia and Actinorhizal Plants", organised in Hammamet, Tunisia from 17th to 19th of March, 2018, gathered scientists from Algeria, Argentina, Belgium, China, Egypt, France, India, Portugal, Senegal, Sweden, UK, USA and Tunisia. The event was a stimulating opportunity for active researchers to share many advances since the previous meeting held in Montpellier, France (Franche et al. 2016) and to discuss new perspectives in this research field.
