Plant Endoplasmic Reticulum
 
All images are of GFP-ER-labelled Arabidopsis or Lotus.
The plants were transformed from DNA of a fusion of GFP with the ER retention signal (usually KDEL, but in this case HDEL).
Many thanks to Jim Haseloff for the DNA and to Hiroshi Kouchi for the transformation and for the last 15 years of cooperative research.
Images were taken on a BioRad-Nikon system at RSBS, ANU, Australia, or the BioRad-Zeiss system at my laboratory in Japan.
