Article by Redei, "A heuristic glance at the past of Arabidopsis genetics":

1) Laibach
First experimental research initiated, 1907, cytological examination of
chromosome numbers and continuity.
Wrote, "Arabidopsis thaliana (L.) Heynh., als Objekt fur genetische und
Entwicklungsphysiologische Untersuchungen., 1943 -- identified many of the
features that make arabidopsis a nice experimental organism (seed yield,
ease of cultivation, low chromosome number, etc.)

2) Reinholz
Mutagenesis by X-rays, thesis 1947.

3) Langridge
Temperature sensitive thiamine auxotroph isolated, 1955 -- "an important

4) Redei
Introduced arabidopsis genetic research to USA, 1956
Obligate thiamine auxotroph, 1960
First linkage information (6 linkage groups), 1964 with Hirono
Many other contibutions

This article goes up to about 1990; with many of the more "modern"
contributions to arabidopsis of Somerville, Meyerowitz, Schell, Feldmann,

The editors write dedicate this book to Redei "who for many years was
almost alone in his appreciation" of Arabidopsis.
