Longitudinal section of root tip of Thale Cress (Arabidopsis thaliana)
The image shows a longitudinal section of a root tip of Thale Cress (Arabidopsis thaliana).
GFP targeted to endoplasmic reticulum (ER) is expressed in the developing protophloem. The protophloem differentiates from the meristematic cells of the root tip to form groups of cells just outside the central core of xylem.
You can relate this image to the ‘plan’ in the image of 'Longitudinal section of root tip of Thale Cress' and link it with the images of 'Dividing cells in root tip, highlighted by GFP', 'Endodermis and cortex in root tip, highlighted by GFP' and 'Vascular tissue in root tip, highlighted by GFP', which form part of a series.
This image was obtained by staining with propidium iodide to show up cell walls and viewing under a confocal microscope. Green Fluorescent Protein (GFP) techniques were used to highlight certain cells in green.
Longitudinal section of root tip of Thale Cress (Arabidopsis thaliana) stained to show cell walls (red) and cells of the protophloem (fluorescing green). The length of the section is approximately 200 µm.
