Bright field microscopic image corresponding to pTERF image showing control S. cerevisiae cox 2-60, and chimeras S. cerevisiae cox2-60-SynJEC3, S. cerevisiae cox2-60-SynBD2, S. cerevisiae cox2-60-SynBD3 and S. cerevisiae cox2-60-SynBD8. Marged image of bright field chimeric cells (at gray) and pTIRF (X100) microscopic images can be predicted using 561 nm laser for visualization of endosymbiont autofluorescence chlorophyl (in red Em.=653/95 nm) from photosynthetically enabled engineered Syn. No such signal was detected from control yeast cells. SP8 Fluorescent confocal microscopic (x63) image of control S. cerevisiae cox 2–60, and endosymbiontic chimera. Marged images: host cell was stained using Conn A-FITC (emission at 510–520 nm wavelength, in green) and cyanobacterial autofluorescence can detected at 616-650 nm wavelength range. The experiment was repeated three times independently with similar results. -- Nature

New Insight Into Chloroplast Evolution

by Keith CowingDecember 12, 2024December 12, 2024

One of the most momentous events in the history of life involved endosymbiosis — a process by which one organism engulfed another and, instead of ingesting it, incorporated its DNA […]
