1. NASC European Arabidopsis Stock Centre: a quick overview ICAR2015

2. Location NASC began in 1990 with 200 stocks from Germany which were then passed on to start our sister centre ABRC in the US. In 2014, NASC and ABRC mirror nearly a million stocks.

3. a) Security – we preserve the seeds under the best possible conditions for longevity and germination frequency. b) Stability – any seeds donated can be recovered if local stocks get compromised or lost (or just lose their germination state) many years after donation. c) Publication – many journals now require seeds to be donated to the stock centres before publication. We give a NASC code on receipt of the seeds. d) Less work – we distribute on your behalf, and your name is associated with the donated stock forever. e) Publicity – we will associate your stocks with documents from your lab, e.g. instructions on use, observations etc, even logos if that is what you want. Benefits

4. Distribution NASC distributes over 100,000 tubes of seed a year

5. Two main centres NASC = Europe ABRC = USA, Canada and Latin America Rest of the world can go to either centre

6. Types of Stocks 6 ecotypes mapping populations characterised mutants multiple markers We hold ~1,000,000 genotypes 99%+ insertion lines knockouts RNAi knockdowns enhancer traps promoter traps transactivation lines activation tags

7. From A to B… Large donations in sufficient quantity can be released immediately We correlate orders with seed stocks; triple pack the seeds for GMO security against accidental release and then finally send the seeds to our users A sample of the original donation of seeds is dried to 5-7% moisture content and stored at -20°C as archival stock. Low quantity stocks are bulked (or re- bulked) under conditions of maximal separation from all other lines for quality control purposes Seed is catalogued and stored at 15% RH, 15ºC in our low humidity rooms Bulking Storage Distribution
