People doing experiments on Arabidopsis who require a lot of tissue might want
to consider the Arabidopsis alternative. Namely to use Brassica (cabbage,
brocolli, canola) to get the materials needed. The Brassica species are in
the same family as Arabidopsis and the genes are highly conserved. Typically
the DNA is >85% homologous (usually in the 90% range). Isolating the material
from Brassica first will make life much easier and in many cases provide
materials unattainable from the little weed.
