Decay of self-incompatibility within a lifespan in Physalis acutifolia (Solanaceae).

ABSTRACT:

Key message

Self-incompatibility decays with age in plants of Physalis acutifolia, and plants that have transitioned to selfing produce fewer seeds but with comparable viability. Self-compatibility in this system is closely related to flower size, which is in turn dependent on the direction of the cross, suggesting parental effects on both morphology and compatibility. The sharpleaf groundcherry, Physalis acutifolia, is polymorphic for self-compatibility, with naturally occurring self-incompatible (SI) and self-compatible (SC) populations. Moreover, SI individuals have been documented to transition to SC with age, at least in greenhouse conditions. Here we tested whether this within-lifespan transition occurs predictably (developmental decay of SI) or could result from a lack of po
