Tobacco plant protoplasts, SEM

Protoplasts. Coloured scanning electron micrograph (SEM) of two tobacco plant (Nicotiana tabacum) protoplasts fusing. A protoplast is a plant cell that has had its tough outer cell wall removed by chemical treatment. This leaves an intact cell with its contents surrounded by its plasma membrane. The cell wall can later be regrown. Fusing protoplasts from two different species into a single cell can produce a hybrid plant. Protoplasts are used instead of intact cells in plant genetic engineering as they are easier to manipulate. Magnification: x2500 when printed 10 centimetres wide

False Colour Fused Fusing Nicotiana Tabacum Plasma Membrane Protoplast Tobacco Plant Cells False Coloured Genetics

EDITORS COMMENTS
This print showcases the intricate world of plant genetic engineering. In this coloured scanning electron micrograph (SEM), we are granted a close-up view of two tobacco plant protoplasts fusing together. Protoplasts, which are plant cells with their tough outer cell walls removed through chemical treatment, retain their intact structure surrounded by the plasma membrane. The removal of the cell wall allows scientists to manipulate these protoplasts more easily compared to intact cells. This technique proves invaluable in plant genetic engineering, as it enables researchers to fuse protoplasts from different species into a single hybrid cell. The potential for creating new and improved plants through this method is vast. With a magnification level of x2500 when printed at 10 centimetres wide, every detail comes to life in this image. The false colouring adds an artistic touch while highlighting the biological intricacies within each fused protoplast. As we gaze upon this mesmerizing photograph, we gain insight into the fascinating world of botany and genetics. It serves as a reminder that scientific advancements continue to push boundaries and unlock nature's secrets for our benefit.
