Clock gene-dependent glutamate dynamics in the bean bug brain regulate photoperiodic reproduction
Fig 8
Schematic illustration shows predicted hierarchical glutamatergic pathway for reproductive control.
Brain glutamate levels photoperiodically change depending on the clock gene period. A glutamatergic signal photoperiodically inhibits the PI neuronal activity via GluCl, which contributes to control of oviposition. The glutamatergic signal may parallelly regulate neuroendocrine centers (such as PL and CA) for photoperiodic regulations of ovarian development. CA, corpus allatum; GluCl, glutamate-gated chloride channel; PI, pars intercerebralis; PL, pars lateralis.
