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.

Today I made a small but momentous start to work in 2026 by changing a single number.
I renamed the file “Papers to write and submit in 2025” to “Papers to write and submit in 2026”.
Stay tuned for more file updates on 1st January 2027.

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 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.

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.

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.

This is what happens when you remove the wall from plant cells. They become perfectly spherical and are called protoplasts.
These protoplasts were isolated from Arabidopsis and transformed with a vector to express cytosolic GFP (in orange). The chloroplast autofluorescence is in grey.

Do you know what happens when you touch a carnivorous sundew plant?
If the touch is strong and large enough, a cytosolic calcium wave will spread from the site of touch throughout the whole plant, but if you only touch one tentacle (see post below), the calcium wave will be local and less intense.
