• His lab was the first to clone an active TE from plants (1982); to show that classic disease resistance genes in plants are both recombinationally unstable and cell autonomous (1988); to use DNA probes from one grass species to map another genome (maize, sorghum), demonstrating genetic collinearity (1990); to show that DNA TEs preferentially insert into hypomethylated DNAs in or near genes (1995); to demonstrate that the majority of plant genomes is composed of LTR-retrotransposons (1996); to show the microcolinearity of plant genomes (1997), and the nature/rate/origin of exceptions to microcolinearity (1999); to explain the timing and mode of both plant genome expansion (1998) and contraction (2002); to show that plant centromeres are hot spots for recombination but not crossing over (2006); to show apparent site-directed recombination in plants (at a disease resistance gene) (2008); to use centromere gain/loss to determine the origin of plant chromosomes (in maize) (2012); to demonstrate a nuclear gain in a teosinte of about 2 Gb of DNA by TE amplification in less than 2 million years (2013); to demonstrate that errors in mismatch base repair may be the most common origin of DNA double strand breaks in plants (2014); to demonstrate domestication-associated changes in root and rhizosphere microbiomes (2018); and to develop the first universal technique to date the origins of allopolyploidy (2020).
• Several hypotheses have been proposed to explain the origin of Sequoia's polyploidy: allopolyploidy by hybridization between Metasequoia and some probably extinct taxodiaceous plant; Metasequoia and Sequoiadendron, or ancestors of the two genera, as the parental species of Sequoia; and autohexaploidy, autoallohexaploidy, or segmental allohexaploidy.
• Hyacinthoides cedretorum is the only tetraploid species in the genus; it is unclear whether it originated by autopolyploidy or allopolyploidy.
• Øjvind Winge was the first to confirm allopolyploidy in 1917, and a later experiment conducted by Clausen and Goodspeed in 1925 confirmed the findings.
