A fluorescence image showing two curved, kidney-shaped plant guard cells forming a stomatal pore. The cells glow in bright magenta, outlining their overall shape, while clusters of distinct round and irregular structures inside them fluoresce green and yellow. The background is completely black.

I pulled this image from the archives of my PhD work, back when I was working with plant and yeast mitochondria.
These are two Arabidopsis guard cells, with their cytosol in magenta, mitochondria in yellow, and chlorophyll autofluorescence in green.

Fluorescence microscopy image of a spherical cluster of chloroplasts, showing magenta-stained interiors surrounded by bright green outlines against a black background.

Moss (Physcomitrium patens) protoplasts (wallless cells) transformed with chloroplast envelope protein tagged with mGFP (green). The chlorophyll autofluorescence is in magenta.
The protrusions of the chloroplast envelope are called stromules.

Fluorescent microscope image showing a dense network of bright green, irregularly shaped plant cells with glowing outlines against a dark background.

Surface (epidermal) cells of many plants are shaped like jigsaw puzzle pieces. 🧩
These are epidermal cells of tobacco (Nicotiana benthamiana) expressing cytosolic EGFP. The bright spherical structures are cell nuclei.

The image shows a round protoplast filled with green, evenly distributed ovoid-shaped chloroplasts. In the center of the cell is the spherical nucleus in magenta.

Happy New Year, everyone. For this #microscopymonday, here is a moss (Physcomitrium patens) protoplast (wall-less cell) transformed with a nuclear marker (in magenta). The much brighter area is the nucleolus. The chlorophyll autofluorescence is in green.
#moss #plantcells

The image shows large moss chloroplasts organized in irregular rows. The chloroplasts, in magenta, are somewhat rectangular in shape but with many irregularities. Many green tubular protrusions extend from the chloroplast surface.

This is what happens to the moss (Physcomitrium patens) chloroplasts when we grow cells on β-lactam antibiotics. β-lactams inhibit the synthesis of the peptidoglycan in the chloroplast envelope, leading to their dramatic expansion.

The image shows two types of plastids, bigger ones with an ovoid shape in grey, and much smaller ones with more complex structures in yellow/orange. The smaller ones also have many filamentous structures expanding from them.

The Arabidopsis thaliana cells can have different types of plastids. In this image, plastids are labeled with the stroma-targeted fluorescence marker RecARed. RecARed fluorescence is false-colored yellow/orange, while the chlorophyll autofluorescence is in grey.

Image shows two elongated cells with rounded tips. The cell periphery and internal structures are visible in different shades of orange. Some internal structures are very small, while others are very big and occupy a large part of the cell. Small cyan-colored ovoid chloroplasts are dotted around within the cells.

During my postdoc, I looked at hundreds of images like this 🤩
These are two apical caulonemal cells from moss Physcomitrium patens stained with MDY64 (shown in shades of orange). The natural autofluorescence of chlorophyll is in cyan.
#microscopymonday #moss #plantcells #plantmicroscopy

The image shows several chloroplasts in green and magenta or both. In the center of the image, five chloroplasts are organized in a circle, and each is making a protrusion towards the center of the circle. The center of these chloroplasts is in magenta, while the periphery and the protrusions are in green.

In preparation for Halloween, these chloroplasts had a seance! 👻🎃
These five Arabidopsis chloroplasts were extending their stromules (protrusions of the chloroplast envelope and stroma) towards each other.

Image shows a filament of three elongated moss cells. The cell outline is in cyan, due to the cell wall staining, while the cell interior appears mostly empty apart from the small and numerous ovoid-shaped chloroplasts in magenta.

This image of moss Physcomitrium patens beautifully demonstrates what we mean when we say that this cell type is characterized by oblique cell walls.
You can see that the cell walls between cells are at an angle and not perpendicular to the cell axis.
#microscopymonday #moss #plantcells

The image shows several elongated rhomboid-shaped cells, filled with ovoid chrooroplasts in magenta, as well as a network of bubble-like vacuoles.

Here are some “leaf” or phyllid cells from moss Physcomitrium patens gametophore. Cells are expressing a green fluorescence marker that labels the vacuolar membrane. Chloroplasts' autofluorescence is in magenta.
Can you spot dividing chloroplasts?

Bloodroot leaf, pressed, with cells visible in the back side.

I picked and pressed one of the bloodroot leaves because I love the shape. Just checked it and the back side of the leaf looks so cool! You can see the cells and they look like a paint-by-number. #bloodrootleaf #plantsarecool #plantcells 🌱
