Programmed cell death (PCD) is a collective term for diverse processes causing an actively
induced, tightly controlled cellular suicide. PCD has a multitude of functions in the …

Pollen-pistil interactions serve as important prezygotic reproductive barriers that play a
critical role in mate selection in plants. Here, we highlight recent progress toward …

Self-incompatibility (SI) mechanisms prevent self-fertilization in flowering plants based on
specific discrimination between self-and non-self pollen. Since this trait promotes …

Self-incompatibility (SI) plays a pivotal role in whether self-pollen is accepted or rejected.
Most SI systems employ two tightly linked loci encoding highly polymorphic pollen (male) …

Plants have evolved diverse self-incompatibility (SI) systems for outcrossing. Ever since
Darwin's time, considerable progress has been made toward elucidating this unrivaled …

Heterostyly is a breeding system that promotes outbreeding through a combination of
morphological and physiological floral traits. In Turnera these traits are governed by a …

Self-incompatibility (SI) is a prezygotic mechanism that prevents self-pollination in flowering
plants by distinguishing between nonself-and self-pollen. It controls sexual reproduction by …

Regulated or programmed cell death (RCD or PCD) is a fundamental biological principle
integral to a considerable variety of functions in multicellular organisms. In plants, different …

Self‐incompatibility (SI) involves specific interactions during pollination to reject
incompatible ('self') pollen, preventing inbreeding in angiosperms. A key event observed in …
