1970's Contributions by M.E. Jones, J.M. Westerman, K. Daly
1967 Lee-Chen with Burger and Steinitz-Sears create first Arabidopsis trisomics; W.J. Feenstra reports using clear plastic sleeves to facilitate seed harvest; G.P. Redéi reports using a dilute agar solution to facilitate seed planting 
1965 First International Arabidopsis Conference held in Göttingen, Germany; F. Laibach retires and G. Röbbelen at the University of Göttingen, Germany assumes curator role for Laibach's ecotype collection
1964 Arabidopsis Information Service newsletter begins publication, G. Röbbelen first editor and original advisory board was F. Laibach, A. Müller, G. Redéi and J. Veleminsky; Redéi and Hirono create first Arabidopsis linkage groups 
1963 A. Müller develops embryo test
1960's Significant scientific contributions in this decade by H.A.S. Hussein,  Cetl, I., G. Rédei (United States), J.H. van der Veen (Netherlands), J. Veleminsky (Czechoslovakia) and G. Röbbelen (Germany), C.W. Lawrence
1950's J. Langridge and K. Napp-Zinn's research demonstrates utility of Arabidopsis for laboratory studies
1947 Laibach's graduate student E. Reinholz publishes first collection of induced mutations; discovers that late flowering can be induced in an early flowering type by X-rays
1943 F. Laibach first recognizes the potential of Arabidopsis as model system for genetics
1937 F. Laibach begins collecting Arabidopsis ecotypes
1935 Russian genetist N.N. Titova, on a Russian expedition to find plants as potential model systems for genetics, rejects Arabidopsis because its chromosomes, miscounted as n=3, were too small
1907 E. Strasburger's graduate student, Friedrich Laibach, correctly observes that Arabidopsis has only 5 chromosomes (2n=10); the lowest odd number known up at that time for a plant; upon graduation, Laibach promptly discontinues working with Arabidopsis for the next 30 years
1900 G. Medel's work on heredity "rediscovered"
1894 Eduard Strasburger publishes 'Lehrbuch der Botanik für Hochschulen'; 35th edition still in publication
1884 Eduard Strasburger, founder of cytology, observes fusion of nuclei following fertilization, publishes 'Theorie der Zeugung''; coins words haploid, diploid, gamete, cytoplasm, nucleoplasm, prophase, metaphase, anaphase, plasmodesms and phototaxis
1841 Taxonomist Gustav Heynhold renames Arabis thaliana as Arabidopsis thaliana (L.) Heynh. in honor of Johnannes Thal
1873 Alexander Braun publishes first non-taxonomic paper on a mutant (presumably agamous) Arabidopsis plant found near Berlin
1865 G. Mendel's first reporting of his foundation work on the principals of heredity went largely ignored
