Photosynth Res. 2018 Aug;137(2):153-159. doi: 10.1007/s11120-018-0488-x. Epub 2018 Feb 16.


We present here a Tribute to Klaus Apel (1942-2017), a photosynthesis pioneer-an authority on plant molecular genetics-in five parts. The first section is a prologue. The second section deals with a chronological discussion of Apel's research life, prepared by the editor Govindjee; it is based on a website article at the Boyce Thompson Institute (BTI) by Patricia Waldron ( https://btiscience.org/explore-bti/news/post/bti-says-goodbye-klaus-apel/ ), as approved for use here by Keith C. Hannon and David Stern of BTI. The third section, which focuses on Apel's pioneering work on singlet oxygen-mediated EXECUTER-dependent signaling in plants, is written by two of us (J-DR and CK). The fourth section includes three selected reminiscences, one from BTI and two from ETH (Eidgenössische Technische Hochschule). This tribute ends with section five, which is a very brief presentation of Klaus Apel's personal life, by Wiebke Apel.

Keywords: Chlorophyll synthesis; Light stress; Photoprotection; Photosynthesis; Protochlorophyllide; Reactive oxygen species; Retrograde signaling; Singlet oxygen.
