We recently isolated a novel adenylyl cyclase/cAMP phosphodiesterase gene from the liverwort,  Marchantia polymorpha . The protein encoded by this gene has a class III adenylyl cyclase (AC) in the C-terminal domain and class I phosphodiesterase (PDE) in the N-terminal domain; therefore, we named it CAPE (COMBINED AC with PDE). CAPE protein is likely involved in spermatogenesis and sperm motility due to its tissue-specific expression pattern in  M. polymorpha  and the distribution of  CAPE  genes in streptophytes. However, little is known about the distribution of  CAPE  in gymnosperms that use motile sperm for fertilization, such as cycads and ginkgo. The present study aimed to isolate  CAPE  genes from the cycad,  Cycas revoluta , the ginkgo,  Ginkgo biloba , and the hornwort,  Anthoceros agerestis . Sequences with high homology to  CAPE  were obtained from these species. Our analyses revealed that all plant taxonomic groups reproducing via motile sperm possessed  CAPE , whereas those that do not produce motile sperm did not possess  CAPE , with one exception in gymnosperm Cupressales. The phylogenic distribution of  CAPE  almost corresponds to the evolutionary history of motile sperm production and further suggests that  CAPE  may be involved in sexual reproduction process using motile sperm in streptophytes.
