Long in the making, but happy to present the Chlamydomonas chlororibosome!
Cryo-ETπ¬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins.
bioRxiv π: shorturl.at/q44tG
This suggests greater chlororibosome diversity than expected!

Fig. 2.Confocal microscopy of N. punctiforme strains. Filaments from the indicated strains were taken from cultures grown in BG110 medium (not induced; A) or after incubation for 24β
h in the presence of Anthoceros agrestis exudates (hormogonia induction; B) and visualized by confocal microscopy. Merged (2 channels) show the overlay of autofluorescence (magenta) and GFP fluorescence (green). Merged (3 channels) represent the overlay of magenta autofluorescence, bright field, and green GFP fluorescence. Hormogonia are identified as short filaments with small cells. Scale bar=20β
