Proposed Symposium Title: NEW INSIGHTS INTO PHYLOGENOMICS, SYSTEMATICS AND EVOLUTION OF SALICACEAE. PART II

Abstract: Salicaceae s.l. include 53 genera distributed worldwide. Salicaceae s.str. comprise about 550 species and represent a diverse and ecological important family of woody plants. Given their species-richness, their ability to hybridize, the vast amount of polyploids and their ecological and economical importance, both, genus Salix and genus Populus turned into model plants for different aspects of plant evolution. In recent years, a lot of progress has been done on (i) phylogenomics, to encipher relationships and spatio-temporal evolution of Salicaceae in a broader scale as well as of willows and poplars (Salicaceae s. str.), including the analysis of hybridization and polyploidization; (ii) on the evolution and analysis of sex determining regions (SDR)/ sex chromosomes in these diecious genera and (iii), on studies of plant-insect interaction including chemical traits. In this symposium we aim to present current research of different aspects of Salicaceae evolution using up-to-date methods and tools. Additionally, we aim to contribute to future networks and projects by bringing together researchers from different geographical regions and fields sharing a common interest in Salicaceae.

Speaker 1: Matt Olson (USA) Texas Tech University, Department of Biological Sciences, Plant population genomics & bioinformatics; Plant mating system evolution; Lubbock, TX, matt.olson@ttu.edu Title: “Challenges for dating divergence times in the Salicaceae: hybridization and fossil calibration”

Speaker 2: Niels Müller (Germany) Thünen Institut, Institute of Forest Genetics, Großhansdorf; niels.mueller@thuenen.de Title "The evolution of dioecy and the molecular mechanisms of poplar sex determination”

Speaker 3: Tao Ma; (China) Key Laboratory for Bio-Resource and Eco-Environment of Ministry of Education & Sichuan Zoige Alpine Wetland Ecosystem National Observation and Research Station, College of Life Science, Sichuan University, Chengdu, China. matao.yz@gmail.com Title: “Diverse History of Salicaceae Sex Chromosomes”

Topics (Up to three): Phylogenetics and Phylogenomics

Topic 2: Plant. Animal, and Microbe Interactions

Topic 3: Hybrids and Hybridization

Justification: The proposed symposium brings together researchers from different continents and bridges four to five topics of the IBC showing the great abundance of Salicaceae in plant research. The organizers come from Europe, North America and China and display a diversity regarding academic age, sex and origin. Given their expertise in Salicaceae research, they guarantee to present a broad variety of high quality speakers from different fields and regions in this symposium. Since especially Salicaceae s.str (i.e., Salix and Populus) act as model organisms for questions on reticulation, polyploidy and sex chromosome evolution, the symposium will attract researchers beyond Salicaceae.
