Comprehensive transcriptomic profiling reveals complex molecular mechanisms in the regulation of style-length dimorphism in Guettarda speciosa (Rubiaceae), a species with “anomalous” distyly [PDF]
Frontiers in Plant Science, 2023 BackgroundThe evolution of heterostyly, a genetically controlled floral polymorphism, has been a hotspot of research since the 19th century. In recent years, studies on the molecular mechanism of distyly (the most common form of heterostyly) revealed an ...

Comparative transcriptomics reveals commonalities and differences in the genetic underpinnings of a floral dimorphism [PDF]
Scientific Reports, 2022 Distyly, a floral dimorphism associated with heteromorphic self-incompatibility and controlled by the S-locus supergene, evolved independently multiple times. Comparative analyses of the first transcriptome atlas for the main distyly model, Primula veris,

Annotation of the Turnera subulata (Passifloraceae) Draft Genome Reveals the S-Locus Evolved after the Divergence of Turneroideae from Passifloroideae in a Stepwise Manner [PDF]
Plants, 2023 A majority of Turnera species (Passifloraceae) exhibit distyly, a reproductive system involving both self-incompatibility and reciprocal herkogamy. This system differs from self-incompatibility in Passiflora species.

Floral organ development combined with pistil transcriptome analysis reveals the role of plant hormone signal transduction in the distyly of Primula vulgaris [PDF]
BMC Plant BiologyDistyly is a widespread phenomenon in flowering plants that enhances pollination accuracy and improves plant environmental adaptability. Primula, the first genus in which distyly is discovered, has become a model system for studying this trait. There are

The rapid appearance of homostyly in a cultivated distylous population of Primula forbesii [PDF]
Ecology and Evolution, 2022 Evolutionary breakdown from rigorous outbreeding to self‐fertilization frequently occurs in angiosperms. Since the pollinators are not necessary, self‐compatible populations often reduce investment in floral display characteristics and pollination reward.

The S-Gene YUC6 Pleiotropically Determines Male Mating Type and Pollen Size in Heterostylous Turnera (Passifloraceae): A Novel Neofunctionalization of the YUCCA Gene Family [PDF]
Plants, 2022 In heterostylous, self-incompatible Turnera species, a member of the YUCCA gene family, YUC6, resides at the S-locus and has been hypothesized to determine the male mating type.

Polygamous breeding system identified in the distylous genus Psychotria: P. manillensis in the Ryukyu archipelago, Japan [PDF]
PeerJ, 2021 Distyly is a genetic polymorphism composed of long-and short-styled flowers in a population. The evolutionary breakdown of distyly has been reported in many taxa, and mainly involves a shift toward monomorphism or dioecism.

Comparative Proteomic Analysis of Self‐Compatible Turnera Mutants Suggests Glutathione S‐Transferase 8 Is Involved in Overcoming S‐Morph Female Self‐Incompatibility Response [PDF]
Plant DirectDistyly is a reproductive system, characterized by the presence of two floral morphs, which promotes outcrossing via physical and biochemical means. In distylous Turnera, the mating type of the S‐morph is determined by two genes: YUC6 (male) and BAHD ...
