Absorption spectra of chromatic acclimators grown in different light colors.

Fluorescence excitation spectra of Synechococcus A15-62, a chromatic acclimator that adjusts its PUB:PEB ratio. The spectra show excitation wavelengths absorbed by the cells and subsequently emitted by the phycobilisomes as fluorescence at 580 nm, when the cells are grown in blue light (blue line) or green light (green line). Absorption spectra of Pseudanabaena CCY9509, a chromatic acclimator that adjusts its PEB:PCB ratio. The absorption spectra are shown for cells acclimated to green light (green line), orange light (orange line), and midway during chromatic acclimation after a switch from green to orange light (black line).

Spectra in were measured in this study using methods described in Sanfilippo et al. (2019) and Stomp et al. (2008)
