| Abstract | 36 Cyclic electron flux (CEF) around Photosystem I (PS I) is essential for efficient photosynthesis 37 and aids photoprotection, especially in stressful conditions, but the difficulty in quantifying CEF 38 is non-trivial. The total electron flux through PS I (ETR1) and the linear electron flux (LEFO2) 39 through both photosystems in spinach leaf discs were estimated from the photochemical yield of 40 PS I and the gross oxygen evolution rate, respectively, in CO2-enriched air. ∆Flux = ETR1 – 41 LEFO2 is an upper estimate of CEF. (1) Infiltration of leaf discs with 150 μM antimycin A did 42 not affect LEFO2, but decreased ∆Flux 10-fold. (2) ∆Flux was practically negligible below 350 43 Page 2 of 35 http://www.publish.csiro.au/nid/102.htm Functional Plant Biology |
