Thank you, Andy, for the insights you have given us into topics that will be of broad interest to many people and I believe will benefit from

those for years to come.   Epilogue In his closing months in Berkeley, Benson worked feverishly with Jacques Mayaudon, a Belgian postdoc, in identifying S. Wildman’s Fraction I protein learn more as Rubisco. Benson left the manuscript with Calvin before departing for Penn State in 1954. Calvin presented the results in 1955 at the International Congress of Biochemistry, mentioning Mayaudon but not Benson (Cavin 1955). The critical AS1842856 concentration findings were published in 1957 with Mayaudon as sole author (1957). It is not clear who submitted the Mayaudon manuscript. Benson became aware of these publications after Calvin’s death more than 40 years later. END OF VIDEO Acknowledgments A number of colleagues helped make this video possible.

“Introduction Photosynthetic acclimation to different levels of growth irradiance has been studied extensively (Boardman 1977; Anderson et al. 1995; Walters 2005). The same is true for growth temperature (Berry and Björkman 1980; Hikosaka

et al. 2006; Sage and Kubien 2007). Acclimation to irradiance and temperature is achieved by similar changes in the photosynthetic apparatus, associated metabolism and possibly shared sensory systems (Huner et al. 1998). The two environmental factors could thus interact in their ultimate effect on the photosynthetic apparatus. However, the combined effect of growth irradiance and temperature on photosynthesis has received much less attention in higher plants (Hikosaka 2005; Fludarabine clinical trial Muller et al. 2005). Reduced growth irradiance typically causes a reduction in the amount of Rubisco, other Calvin cycle enzymes and components of the electron transport chain, all expressed per unit leaf area. However, chlorophyll content remains generally rather constant (Hikosaka and Terashima 1996), causing a change in the balance between light harvesting and photosynthetic capacity in favor of the former. The change in the balance is achieved by an increase in light harvesting complex (LHC) relative to core chlorophyll, which is reflected in a lower chlorophyll a/b ratio (Anderson et al.
