Cyclic electron transport around photosystem-I, and the associated cyclic photophosphorylation process in chloroplasts is enabled by two pathways, which depend on the PGR5 protein and the chloroplast NADH dehydrogenase-like complex, respectively. When both pathways are defective, photosynthesis and plant growth are significantly impaired. The pgr5 mutant of Arabidopsis is particularly sensitive to fluctuations in light intensity, which can lead to photodamage of photosystem-I. The lecture will discuss the molecular mechanism of the photoprotection of photosystem-I, afforded by this cyclic electron transport process.
We host five endowed lectures throughout the academic year. Endowed lectures are paid for with private funds invested and held by the Regents of the University.
The Daniel I. Arnon Lecture was established with resources from the Charles F. Kettering Foundation. The endowment also supports graduate students who are designated Arnon Fellows.
The Bob B. Buchanan and Harry Tsujimoto Lectures were established with a generous gift from the K/T (Kase/Tsujimoto) Foundation of San Francisco. The endowment also supports graduate students who are designated "Kase Fellows".
The Taylor-White Lecture is a unique collaboration between Tom White, an entrepreneur, and John Taylor, a professor in the department. Together they performed research and published papers.
The Kustu Lecture is supported by donations from students, faculty and staff who worked with Sydney Kustu, a professor in the department.
