It’s just amazing. I really need to think about this. Four different plasmids with pigment genes. Grown up in E. coli individually, mixed, and plated. Wow. @univpugetsound @ASMicrobiology
@markowenmartin @univpugetsound @ASMicrobiology The formation of spatial sectors (from different founder cells) is an interesting phenomenon that has been studied in population ecology! pnas.org/doi/full/10.10…
@markowenmartin @univpugetsound @ASMicrobiology When you transform Chlamydomonas with YFP and look under a stereo microscope, they look like this sometimes too (YFP expression though)
@markowenmartin @univpugetsound @ASMicrobiology I like how thee colonies look when the plasmids are mixed. Are some plasmid types expressed while others are not?
@markowenmartin @univpugetsound @ASMicrobiology A colorful reminder that a single CFU (stands for Colony Forming Unit) does not always represent a single bacterial cell?
@markowenmartin @univpugetsound @ASMicrobiology How old are those colonies?
@markowenmartin @univpugetsound @ASMicrobiology Beautiful! I've been dealing with the "why do I seem to have so many plasmids per cell!!!" drama. What strain of E coli are these?
