“…Plants that mimic mushrooms, including the exceptional fungal mimetic Arisaema species ( A. sikokianum ), are visited by various fungivorous insects such as Mycodrosophila species (Drosophilidae) and staphylinids (Coleoptera; Kakishima et al, 2019; Matsumoto et al, 2019; Matsumoto et al, 2021). In contrast, many other Arisaema species (especially Pistillata taxa) are exclusively pollinated by a limited number of fungus gnat species (one or two) (Suetsugu et al, 2021). This raises the question of whether most Arisaema species have evolved to mimic mushrooms.…”
Section: Putative Sexual Deception Systemmentioning
Female individuals in the genus Arisaema are the only plants known to imprison their pollinators permanently. Their lethal pollination system has long attracted the interest of evolutionary biologists and naturalists. Nonetheless, the mechanisms of how Arisaema plants lure their victims to the brink of death are only just being unveiled. Here, I briefly review the unique reproductive biology of these plants, focusing on the possibility of sexual deception to lure pollinating victims, and its role in the evolution of new species.

Section: Possible Adaptive Radiation In Arisaema Section Pistillatamentioning
The adaptive radiation of flowering plants as manifested by the floral diversity has long been considered associated with the diversity of plant–pollinator interactions, because changes in plant–pollinator interactions are hypothesized as one of the major mechanisms driving plant ecological speciation. To understand the relative contributions of various mechanisms for plant radiation, including pollinator changes, it is useful to study a plant group for which comparative study of the species life history across the whole lineage is feasible. To this end, we will focus on the plant lineages that have presumably radiated in the Japanese archipelago, namely, the genera Asimitellaria, Asarum, and Arisaema. By comparing these three genera, we will comment on the possible modes of adaptive radiation and diversification among the endemic flora of Japan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
