Summary: suspension culture in Arabidopsis

[Shinhan]

The following messages are the response I get for a question regarding the use 
of suspension culture for enzyme assay in Arabidopsis. There are certain 
references being cited more than once. In order to retain the original 
message, I didn't do too much editing. Thanks for those who provide 
information about my question.

  Arabidopsis thaliana protoplasts derived from rapidly established
  suspension cultures. Doelling and Pikaard. The suspension cultures
  grow very well but it is difficult to get good protoplasts for 
  transient expression studies.

 *We make suspension cultures as needed, and also regularly isolate
  protoplasts from mesophyll cells for transient expression assays.

  yeast!

 *I find a common way to get suspension cultures form arabidopsis is   to use 
shoots and induce the formation of callus by transfer on to a   callus 
induction media (CIM).  After callus formation transfer to   suspension media 
(SM). From May, M.J. and Leaver, C.J. (1993).   Oxidative stimulation of

 *Try the Hahlbrock lab at the Max-Planck Institute in Cologne, Germany
  (for example, contact Dr. Imre Somssich or Dr. Bernt Weisshaar) - 
  they have a suspension.
 *Dr. Keith Davis at Ohio State University may also have one.

 *For suspension cultures (or better liquid in vitro cultures) of
  Arabidopsis look into the following puplications:
 (1) Ford: Plant Cell reports (1990) 8: 534-537,
 (2) Mathur et al.: Plant Cell reports (1995) 14: 221-226,
 (3) Wenck and Marton: BioTechniques (1995) 18: 640-643.
 *We also have an (unpublished) protocol starting from seedling tissue
  in MS-medium with 2,4-D. If you are interested please let me know.
 *I also found in the meanwhile a number of other publications
  concerning suspension cultures in Arabidopsis or where the authors
  used in liquid cultured cells to eg. isolate protoplasts or to study
  gene  expression. Note, that in some cases the cultures seem not to
  consist of fine dispered cell colonies of even single cells, like for
  instance in carrot cell suspensions.
