Welcome to Nitrogen2019

The Fourth International Symposium on the Nitrogen Nutrition of Plants

We are delighted to welcome you to Nanjing, China to the 4th International Symposium on the Nitrogen Nutrition of Plants (ISNNP). This triennial symposium was agreed during the Third ISNNP held at Montpellier, France in 2016 and is the continuation of a long-standing tradition of international nitrogen meetings, initiated by both the ENAAG (European Nitrate and Ammonium Assimilation Group) and NAMGA (Nitrate Assimilation: Molecular and Genetic Aspects) organizations. ENAAG held meetings in Jarandilla de la Vera (Spain, 1986), Naples (Italy, 1989), Tiberias (Israel, 1992), Darmstadt (Germany, 1995), Luso (Portugal, 1998), Reims (France, 2001), and Wageningen (The Netherlands, 2004). NAMGA group held meetings in Gatersleben (DDR, 1982), St Andrews (UK, 1987), Bombannes (France, 1990), Tampa (USA, 1997), and Cordoba (Spain, 2002). A significant change occurred in 2007, when ENAAG and NAMGA decided to hold a joint meeting, Nitrogen2007 in Lancaster (UK), and to merge during this meeting to give birth to one single organization. As a consequence, Nitrogen2007 was the founder meeting of a new series of Nitrogen symposia, which aimed at gathering a larger international audience, especially from Asia and America. Therefore, Nitrogen2007 was followed by Nitrogen2010 in Inuyama City (Japan, 2010), Nitrogen2013 in Puerto Varas (Chile, 2013), and Nitrogen2016 in Montpellier (France 2016), which were then the First, Second, and Third International Symposium on the Nitrogen Nutrition of Plants, respectively.

We feel greatly honored that the International Scientific Committee of ISNNP has chosen Nanjing as the venue for the 4th ISNNP. Nanjing, located in the Yangtze River delta, is an ancient capital of China, serving as the capital city for ten dynasties during its 2,500 years history. Nanjing not only has a prominent place in Chinese history and culture, but also is one of the major research centers and higher-education hubs in modern China with particular strength in soil science and plant nutrition.

The main objective of this triennial international nitrogen conference will be to review recent progress in the understanding of molecular physiological and developmental processes involved in the nitrogen nutrition of plants and emerging of breeding high nitrogen use efficiency (NUE) crops. Nitrogen2019 will offer an excellent platform for fostering exchanges and collaborations within the rapidly expanding scientific community interested in these topics. The conference will gather together many world-leading experts in the field, and will also provide young researchers with possible funding an opportunity to present their work. The oral presentations will be given by the invited speakers with a wide variety of background and experience and the individuals selected from the submitted abstracts. The program of the symposium will include seven oral sessions and two poster sessions covering the following plant N-related topics:

- Transport

- Metabolism

- Sensing and signaling networks

- Interaction with other nutrients

- Plant-microbiota association

- Use efficiency from cell to field

- Broader perspectives in Agriculture

A special issue of the Journal of Experimental Botany is being considered in connection with the Symposium. We welcome proposals for both reviews and original research papers which should include the preliminary article title, author(s) and a short outline for the review or preliminary abstract for the research articles before February 28th, 2019.

I very much look forward to seeing you in Nanjing. Please visit our website regularly for any updates and news on the conference.
