This is a portal to scientific and educational datasets.

Current Research Interests in the Griffing Lab in the Department of Biology, Texas A&M University.

1. Investigating how the tubule and cisternal network of the endoplasmic reticulum (ER) can serve as a circulation network among the organelles, including the plasma membrane and chloroplast.

Click here for movies that compare the movement of the ER in plants and animal cells and in different plant tissues.

Click here for a review article on "Networking in the endoplasmic reticulum".

2. Analysis of the effects of ER stress on ER remodeling and directional flow and on Golgi movement.

Click here for a paper on transient ER stress induced by photostimulation of the chloroplast/ER nexus.

3. History of imaging in science, particularly botany.

Click here for an article about a recent paper on the use of images in the earliest dichotomous key.

4. Discovering how grizzly bears behave using archived datasets of from five years of summertime video at a salmon run.

Lab Procedures:

Many of the protocols are now on omero.bio.tamu.edu.

Picture  of the day:  Persistency mapping the endoplasmic reticulum (ER). The dark lines are tubules persisting longer than 5 seconds. The green shows tubules from a single frame of moving ER. Red arrows show the direction of movement in the fast lanes.
 
A major hypothesis developed by the lab: The ER is the circulatory system of the plant cell.
 
Trans-dimensional imaging: biological imaging that crosses time and space to observe phenomena not otherwise easily studied.
