ICAR 2017 KEYNOTE LECTURES19 June 6:30 pm: Keynote Lecture 1: A day in the life of Chlamydomonas and other storiesSabeeha Merchant, UCLA, USATechnological advances in the last decade present enormous opportunities for biologists. We are no longer restricted toahandfulofreference/modelorganismsforaviewoffundamental pathways in plants, animals and microbes with molecular resolution. We can sample the diversity of extant life for a retrospective view of adaptation and evolution, giving us deeper mechanistic understanding of function, and sub-cellular structures and interactions can be visualized with atomic resolution. There is great potential for continued discovery, for expanding our knowledge base, ultimately for improving the quality of life. Three vignettes will be presented: 1) a collaboration with the Niyogi and Pellegrini groups in which we bring a previously uncharacterized organism, Chromochloris zofingiensis, to the status of a model organism with a high quality genome assembly and imaging of intracellular structures, 2) a collaboration with Ralle to visualize intracellular metal stores in Chlamydomonas with high spatial resolution, revealing highly organized structures, and 3) use of DOE user facilities for temporal resolution of macromolecular and wcentral metabolism during the Chlamydomonas cell cycle.

20 June 7:00 pm: Keynote Lecture 2: Ionome to Genome: Tales of Gene Discovery Mary Lou Guerinot, Dartmouth College, USAUnderstanding how seeds, often the edible portion of the plant, obtain and store nutrients is key to developing crops with higher agronomic and nutritional value. Most of our work has been focused on the essential micronutrients iron, manganese and zinc. Combining genetics, high throughput elemental analysis via ICP-MS and high resolution imaging via synchrotron X-ray fluorescence, we have identified and characterized a number of Arabidopsis mutants that have increased tolerance to iron deficient growth conditions and have increased iron accumulation relative to wild type plants. One of these, Ig14, has a similar metal content to wild type when grown on normal soil, but thrives on alkaline soil, accumulating significantly more iron in its shoot and seeds. A triple mutant of three closely related negative regulators of the iron deficiency response has increased tolerance to iron deficient growth conditions and increased iron accumulation without resulting toxicity. We have also uncovered unique patterns of iron and manganese localization in seeds and have now identified the genes responsible for setting up these patterns, allowing us to determine whether the patterns are biologically significant and, ultimately, whether they can be altered in support of biofortification of staple crops. We are also taking similar approaches to determine how arsenic, a non-threshold, Class 1 human carcinogen, accumulates in plants. Rice, a staple food for over half the world’s population, represents a significant dietary source of arsenic. It is imperative that strategies to reduce grain arsenic are developed, and identifying the mechanisms that enable arsenic to reach and accumulate within the rice grain is key to this endeavor.

22 June 7:00 pm: Keynote Lecture 3: Breaking the silence: Making decisions in the world of uncertaintyKeiko Torii, HHMI and University of Washington, USAIt has become evident that plants use a myriad of secreted peptides and small chemicals to coordinate their growth, development, and response to environmental insults. These signals could work for long-distance, a shoot-to-root communication for physiological adjustment, a short-distance paracrine manner, or an autocrine manner to coordinate developmental potential of plant tissue patterning. Owing to the importance of plants for our environment and sustenance, new approaches are needed to further understand and manipulate plant growth and development. To this end, we are forming a cross-disciplinary team of scientists, including synthetic organic chemists, structural chemists, and plant biologists to develop artificial ligands and receptors to probe, understand, and manipulate plant growth and development. I will describe our collaborative effort to move forward, and how our tools provides conclusive evidence for a classic, unresolved question in plant signaling.

23 June 11:00 am: Keynote Lecture 4: “Disease-climate-microbiome” triangles in the phyllosphereSheng Yang He, Michigan State University, USAOne of the most significant challenges of the 21st century is to discover innovative ways of increasing global crop production to meet the demands for food from the growing human population. A major roadblock to global food sufficiency is persistent loss of staple crops to pathogen infections. Greater efforts are needed to accelerate the buildup of a comprehensive knowledge base thatexplainshowplantdiseasesoccur;howplantsdefendagainstmicrobialpathogens;andhowdynamicclimateconditions impact plants, microbes, and their interactions. In 1960, RB Stevens (Plant Pathology, an Advanced Treatise. Vol. 3, Academic Press, New York) formulated the famous “Disease Triangle” concept, proposing that plant disease outbreaks require not only a susceptible plant and a virulent pathogen, but also conducive environmental conditions. For practical reasons, however, most contemporary investigations into plant-pathogen interactions at the molecular level devote little effort to understanding why climatic conditions, such as humidity and temperature, have a profound effect on pathogen virulence and host susceptibility. Moreover, these studies often ignore the potentially pervasive effect a plant’s endogenous microbiome may have on basic plant health and host-pathogen interactions. In this talk, I will give an example of interplays between disease, humidity and microbiota during Pseudomonas syringae infection of Arabidopsis thaliana leaves. Future studies of plant-pathogen interactions should increasingly consider the multi-dimensional nature of “disease-environment-microbiome” interactions that are more reflective of what occur in crop fields and natural ecosystems.

Workshop 1: New and Updated Bioinformatics Datasets, Tools and Resource. Organizers: Eva Huala, TAIR and Phoenix Bioinformatics, and Chris Town, Araport and J. Craig Venter Institute. Room Location: Park View Room

This workshop includes a series of short talks from several major Arabidopsis data and stock resources, aimed at providing a quick overview of what’s new at each one. Designed for both experienced researchers needing a reminder on what is available and those new to Arabidopsis research, we will aim to bring researchers up to speed on the latest developments, to ensure that everyone is aware of what is available and can take full advantage of the latest tools, data and resources in their work.

5:45 - 5:54 pm: Araport. Chris Town, Vivek Krishnakumar (J. Craig Venter Institute). We will demonstrate how to search, analyze, and download a wide array of data (including the Araport11 annotation integrated with RNA-seq expression, coexpression, physical and genetic interactions, pathways, seed stocks, publications, and more) through the core components ThaleMine and JBrowse. ThaleMine also provides a user-friendly interface for running gene list enrichment analysis, building data queries, exportingdatatables,andsaving/sharingwork.Tofurtherenhance data sharing, discovery and re-use by the community, we are developing simple mechanisms for users to automatically integrate their data sets with Araport simply by providing the appropriateGFForBAMfileandassociatedmetadata.

5:54 - 6:02 pm: New data and features at TAIR. Eva Huala, Shabari Subramaniam (Phoenix Bioinformatics). With direct funding from the research community, TAIR (www.arabidopsis.org) continues to add new experimental gene function data from research literature. We will present a quick overview of new data and features at TAIR, including our new Gene Family band enabling researcherstomoreeasilyfindorthologsinotherplantsandview them in a phylogenetic tree. We will also demonstrate how to submit your new gene function experimental results to TAIR, where they will have increased impact and visibility to the plant research community.

6:11 - 6:20 pm: 1001 Genomes. Arthur Korte (University of Würzburg). The 1001 Genomes Project was launched 2008 to discover detailed whole-genome sequence variation in differentArabidopsisaccessions.Seedsfromtheseaccessionsare available from the stock centre.As unlimited numbers of plants with identical genotype can be grown and phenotyped, the sequence information can be used directly in association studies. Recently we published the detailed analysis of 1135 genomes, which enables the construction of a comprehensive “genotype-to-phenotypes” map and allows meta-analyses of pleiotropy. We developed various databases and tools ranging from web-applications for GWAS, a phenotype database and tools to identify A. thaliana strains.

6:20 - 6:29 pm: New tools and resources for the Arabidopsis community from the ABRC. R. Keith Slotkin, ABRC team (Ohio State University). Located at The Ohio State University, the Arabidopsis Biological Resource Center (ABRC) serves the plant biology community by distributing Arabidopsis seeds, DNA clones from Arabidopsis and other plant species, as well as teaching and outreach resources. Recent improvements to the ABRC that will be discussed include new seed and DNA clone stocks, new quality control technologies and pipelines, and new teaching and outreach kits. In addition, the ABRC will be providing an update on the development of a new public database platform for all stocks hosted at the ABRC.

6:29-6:37pm:TheNottinghamArabidopsisStockCentre(http://www.arabidopsis.info) - An update. Marcos Castellanos-Uribe, Sean May (University of Nottingham). NASC received 6,875 new stocks in 2016 including 4,452 GABI-Kats, 1,302 SALKs, 236 ecotypes and 885 small donations. Most notable additions to our catalogue include the new Koornneef ecotype lines, CAB and CCA mutants from Prof. Andrew Millar and several SALKSeq stocks from Joe Ecker. Based on customer feedback, we now offertheoptiontoaddphytosanitaryrequeststoanyorderandtodeliverseedstocksbyexpress/courierdeliveryforastandardfee.

RIKEN BioResource Center (BRC) distributes research materials such as seed lines, cDNA clones and cultured cell lines to the internationalscientificcommunity.Wehavestarteddevelopinga systematic web-database that allows user scientists to obtain entire information of materials in RIKEN BRC. In order to make the database useful enough for the scientists, we encourage attendees to provide us any suggestions and comments.

Workshop 2: The ADAPTOMICS workshop on emerging Brassicaceae model species (DFG SPP1529). Lead Organizer: UteKrämer(ADAPTOMICSCoordinator),RuhrUniversityBochum;and Miltos Tsiantis, Max Planck Institute for Plant Breeding Research, Cologne. Room Location: Mills 3

Arabidopsis thaliana is the most developed plant model, whichcontinuestoallowgreatscientificprogressintheplantsciences. The very biology that facilitated the success of Arabidopsis as a model organism, however, implies that highly important research questions cannot be addressed in this species. The German DFG-funded Research Priority Programme 1529 ADAPTOMICS (“Evolutionary Solutions to Ecological

Challenges: Molecular mechanisms underlying adaptive traits intheBrassicaceaes.l.”;www.adaptomics-dfg.de)hasbeenworkingtowardsfillingthisgapoverthepastsixyears.Thegoalofthisresearchprogramistoemploythebenefitsaffordedbygenomics and high-throughput sequencing technologies in ordertoaddresstraitsandscientificquestionsthatcannotbestudied in Arabidopsis alone, while taking maximal advantage of knowledge, tools and resources available for this closely related species. This workshop will showcase the successful development of novel Brassicaceae model species and genome-enabled approaches towards understanding the molecular mechanistic basis, ecological roles and evolutionary history of important phenotypic traits that are not found in A. thaliana. There will be one established speaker from within the ADAPTOMICS consortium (I) and two selected speakers from outside the consortium who are young PIs (II, III).

5:45-6:09 pm: Exploiting Cardamine hirsuta to understand the genetic basis for evolution of plant form. Prof. Dr. Miltos Tsiantis, Director, Max Planck Institute for Plant Breeding Research, Cologne, Germany.

Workshop 3: Overcoming the Imposter Phenomenon in Academic Science – an interactive workshop to combat imposter thoughts. Organizer: Rebecca Mosher, University of Arizona. Room Location: Mills 6

Imposter Phenomenon (IP, or Impostor Syndrome) is the persistent feeling that you aren’t as smart as your colleagues, that your success is due to luck rather than your abilities, and that you are an ‘imposter’ who will one day be discovered. IP wasfirstdescribedforhighachievingwomen,butitiscommonamong other underrepresented groups as well as the population as a whole. IP is particularly prevalent among high achievers and inacademicrealms.ThereareanumberofnegativeeffectsofIP,including anxiety, overwork, and avoiding interaction.

One of the most powerful ways to combat IP is to acknowledge it and understand that many people feel this way. This workshop willdescribeIPandthemanywaysitcanmanifest;discusstheimpactsofIPonscientificcareers,andacademicscienceinparticular;andprovidespecificstrategiestorecognizeandcombat imposter thoughts. The workshop is interactive and participants are encouraged to discuss their experiences in small groups or anonymously. Although primarily aimed at those who have experienced imposter thoughts, the workshop will also educate supervisors so that they can be better mentors. Attendees will leave with a clear understanding of Imposter Syndrome, the ability to recognize imposter thoughts in themselvesandothers,andspecificactionstotaketo combat Imposter Syndrome.

You will be allowed to load your talk if you come outside of your prioritized timeframe, however, we may ask you to wait to accommodate invited speakers that speak earlier in the program (and are in the prioritized window.)

1. We will have additional laptops in the speaker-ready room if you wish to quickly review your slides, however you will not be able to do significant editing on the shared laptops so that we can accommodate as many people as possible.

2. You must load your talk no later than 1.5 hours prior to your session start time, andideallyseveralhours/1daybefore.

3. Note the speaker ready room hours below carefully. If your sessionisTue/Wed/Thursafternoon(e.g.2or4pm)you must load your talk no later than 1 pm that day.

4. We will be unable to load talks during the sessions as the program is very tight. Therefore, please have your presentations complete when you arrive in St. Louis, particularly if you are speaking on the second day (Tuesday), so your talk can be loaded on Monday.

5. The conference supplies PC laptops and you must load your talk onto the conference PC laptops (as outlined in the table).
