The 11th IPMB Congress was be held 25–30 October 2015 in Iguazú Falls, Brazil, bringing together leading scientists in this area. Luckily for us we had Michelle Cotta there tweeting for us. However she wasn’t the only person there on Twitter and there was some impressive stuff to tweet.

Annals of Botany had an interest at the event, with the announcement of a special issue on Plant Immunity, coming in 2016.
