The IPMB congress is a triennial meeting gathering 1500-2000 plant molecular biologists from all over the world since 1984. The IPMB2015 was held in Brazil (Iguazu) and was preceded by IPMB2012 in Korea (Jeju Island) and IPMB2009 in USA (St Louis). Each of the previous meetings demonstrates the importance to develop multidisciplinary approaches to face climate changes and population increase. IPMB2018 will follow up with an attractive scientific program highlighting major impact recent discoveries from basic molecular biology to crop biotechnology. Combination of plenary and parallel sessions will demonstrate the importance of plant molecular biology to fulfill the need for the development of an ecologically intensive farming.
