Mp7g08500	MpCAPE	experimental subject	Marchantia CAPE encoding combined class III adenylyl cyclase (C-terminal) and class I phosphodiesterase (N-terminal) domains; biochemical assays confirmed both domains are enzymatically active, with cAMP-specific PDE and a low-activity high-affinity AC. Shown to be specifically expressed in spermatogenous cells of antheridia but not vegetative organs, serving as the functional reference for CAPE in motile-sperm streptophytes.
