National Meeting of the Spanish Society of Nitrogen Fixation (XV SEFIN)
This special issue of Symbiosis contains a selection of the papers presented at the XV SEFIN, the National Meeting of the Spanish Society of Nitrogen Fixation (SEFIN in the Spanish acronym), held in León (Spain) from 16th to 18th June 2015. Since 2008, the SEFIN meeting has been celebrated with the Portuguese-Spanish Congress on Nitrogen Fixation, and this was the 4th occasion. The slogan of this international event was “The bridge between biotechnology, agriculture and environment”, which expresses the intention and efforts of the SEFIN to transfer scientific findings and knowledge to a broad spectrum of the scientific society including the biotechnological industry, agriculture and those involved in the protection of the environment. The Congress was an international event, which brought together more than 110 scientists from four continents: Europe, Asia (Middle East), America (Latin America and the Caribbean) and Africa.
The papers contained in this special issue cover all aspects of the biological nitrogen fixation and beneficial plant-microbe interactions: i) four papers on Ecology, diversity, and evolution of Plant Probiotic Microorganisms (PPM); (ii) three papers on genetics, genomics and proteomics of PPM and their associated plants; iii) one paper about plant-microorganism interactions; iv) two papers on the physiology and biochemistry of beneficial microorganisms and associated plants; v) and three papers on inoculants for agriculture and environmental science. Thus, the topics cover aspects from the molecular level and the physiological one to field trials, and from regulatory aspects to the communication between plants and microorganisms.
The Congress consisted of keynote lectures that were given by Prof. Yaakov Okon (Department of Plant Pathology and Microbiology, Faculty of Agriculture, Food and Environment, The Hebrew University of Jerusalem, Israel) and Dr. Euan James (The James Hutton Institute, Invergowrie, Dundee, UK), linked with the five sessions mentioned above. The sessions consisted of 36 contributed oral presentations, plus 59 posters, all were authored by young graduate students in association with their major professors and the lab teams from their institutions.
