Identification of putative circadian clock cells in a heteropteran insec, Pyrrhocoris apterus
Syrová, Zdeňka ; Hodková, Magdalena ; Doležel, David ; Šauman, Ivo
We identified per expressing cells in compound eyes, pars intercerebralis of brain and corpora cardiaca, while PDH-immunoreactivity was found in lateral neurons between central brain and compond eyes. Removal of the compound eyes resulted in a loss of the circadian rhythmicity
