Quantum Efficiency of Wild-Type, lto1, and LTO1-Complemented lto1 Lines

Strain	Medium	FV/FM (±sd), n = 5
Wild type	MS	0.828 ± 0.007
lto1	MS	0.581 ± 0.068
lto1 + LTO1	MS	0.831 ± 0.005
Wild type	MS + Suc	0.815 ± 0.008
lto1	MS + Suc	0.522 ± 0.113
lto1 + LTO1	MS + Suc	0.828 ± 0.003

Maximum quantum yield of PSII (F_V/F_M) was measured as described in Table 3 and Methods. Each type of plant was grown from seeds on Murashige and Skoog (MS) or Murashige and Skoog + 2% Suc medium under moderate light (~80 μmol PAR photons m⁻² s⁻¹). Leaves from five separate plants were removed and immediately assayed.
