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) with dividing cells highlighted by Green Fluorescent Protein (GFP) techniques. The central two GFP expressing cells show the quiescent centre of the root apical meristem. The outer two GFP expressing cells show the cells that will develop into the cortex and endodermis.
You can relate this image to the ‘image’ of 'Longitudinal section of root tip of Thale Cress' (which can serve as a ‘plan’) and link it with the images of 'Endodermis and cortex in root tip, highlighted by GFP', 'Vascular tissue in root tip, highlighted by GFP' and 'Protophloem 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.
The length of the section is approximately 200 µm.
