In the lab, I like to look at equipment and play guessing "Who is younger - the lab equipment or me?" 😅

... you win this round, freeze dryer😋
Me in the lab in a labcoat next to our freeze dryer. The glass beakers can be connected and the vacuum extends into the beakers with the sample in them. Black tubes connect the beakers with the vacuum chamber and white valves allow for individual connecting and disconnecting.

This week, I processed my plant samples further🌱. I cut the areas where I injected the sample in the tobacco plants, put the pieces in little aluminium foil bags, freeze dried them and scaled equal amounts of dry leaf pieces. Scaling milligrams of leaf pieces needs quite some patience😅

The scale is resting on a special heavy table that prevents vibrations of the table to influence the scaling. A red rack with sample tubes is standing next to the scale as well as a clean tissue paper with two metal tweezers on it. A piece of clean tissue paper with two metal tweezers on it. Between the tweezers is a 2 ml reaction tube with a metal bead and freeze dried tobacco leaf pieces in it.

I use a syringe to inject liquid containing an enzyme that damages the plant cell wall into young tobacco plants. You see the liquid as dark spots. This is Nicotiana benthamiana (the wild relative of N. tabacum, the more famous tobacco plant). Excited to see how the plants react to the treatment 😁😁😁
Nicotiana benthamiana plants in flower pots on a black tray. A syringe and a pen are next to the pots on the tray. Where liquid has been injected into the leaves, it is visible as darker spots on the green leaves.

When I talk to friends, family or others that don't work in research, I am often surprised and amused when I learn how they imagine me working in the lab 😅 So I thought I’d start sharing more from my everyday work doing plant science 👩‍⚕️🌱

This is me treating tobacco plants (Nicotiana benthamiana) to study their immune reaction when their cell wall is damaged. I am wearing a red lab coat and a hair net to prevent carrying seeds or pollen outside of our secure facility.

Super excited to start my new position in the Hydrosensing ERC Synergy Project😊 It was amazing to get a preview in Regensburg and meet all you nice and inspiring people!
Looking forward to two more years as part of this excellent, international team!
