(A) A false-color transmission electron micrograph of a Chlamydomonas
reinhardtii cell. The chloroplast is highlighted in magenta and the
pyrenoid matrix in orange.
(B) Tagging and mass spectrometry pipeline. Target genes were amplified by PCR
and Gibson assembled in frame with Venus-3xFLAG, under the constitutive
PSAD promoter. Transformants were screened for fluorescence
using a scanner, and arrayed to allow robotic propagation. Lines were either
imaged using confocal microscopy to determine their spatial distribution or
batch cultured for affinity purification-mass spectrometry (AP-MS).
