Happy #FluorescentFriday! Here's some autofluorescence of #Mimulus trichomes on tiny leaves and I saw something very interesting - the brightest cells appears to be a small "neck" cell connecting the long stalk and the head of the trichome! No idea why but they look like cute tiny shiny donuts 😋🍩🔬🌱
Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...
