Table 1. Photo-conversion behavior of FPs in diatoms.

FP	Photo-conversion mechanism	Cytosolic expression		Silica embedded		Suitable for silica embedded imaging
		Before activation	After activation	Before activation	After activation
PATagRFP	PA	Dark	Orange	Dark	Dark	No
PAmCherry1	PA	Dark	Orange	Dark	Dark	No
PA-GFP	PA	Dark	Green	Dark	Dark	No
mEOS3.2	PC	Green	Orange	Green	Orange	Yes
Dendra2	PC	Green	Orange	Green	Orange	Yes
Dronpa	PS	Dark	Green	Dark	Green	Yes

All FPs used for SMLM in diatoms together with the respective screening results are listed. Abbreviations for the conversion mechanism are: photo-activatable (PA), photo-convertible (PC) or photo-switchable (PS). Color names represent the excitation wavelengths 488 nm (green) and 561 nm (orange).
