Genomic analyses elucidate S‐locus evolution in response to intra‐specific losses of distyly in Primula vulgaris [PDF]
Ecology and EvolutionDistyly, a floral dimorphism that promotes outcrossing, is controlled by a hemizygous genomic region known as the S‐locus. Disruptions of genes within the S‐locus are responsible for the loss of distyly and the emergence of homostyly, a floral ...

Investigating the effects of fire on pollinator-dependent distyly polymorphism. [PDF]
Plant Biol (Stuttg)Fire influences plant traits in several ways, but its effects on flower polymorphisms are unknown. Distyly, a floral polymorphism with long‐styled (L‐styled) and short‐styled (S‐styled) morphs exhibiting reciprocal herkogamy and a self‐incompatibility ...

Evolution of distyly breakdown in Palicoureeae Robbr. & Manen and Psychotrieae Cham. & Schltdl. (Rubiaceae) [PDF]
Acta Botânica Brasílica, 2022 Distyly is a floral polymorphism with reciprocal placement of male and female structures, heteromorphic self-incompatibility, and other ancillary traits. However, breeding system breakdowns and loss of polymorphism are common.

Genomic studies in Linum shed light on the evolution of the distyly supergene and the molecular basis of convergent floral evolution. [PDF]
New PhytolDistyly, an example of convergent evolution, is governed by a supergene called the S- locus. Recent studies highlight similar genetic architectures of independently evolved S-loci, but whether similar regulatory pathways underlie convergent evolution of ...

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 ...

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

Phenology and floral morph variation suggest non-classical distyly in the Sisrè berry plant [Synsepalum dulcificum (Schumach. & Thonn.) Daniell, Sapotaceae] [PDF]
BMC Plant BiologyBackground Understanding floral biology and phenological variation patterns in plant species is crucial for hybridization and genetic improvement. In Synsepalum dulcificum (Sisrè berry plant), the lack of such knowledge hinders proper mastering of the ...

Is distyly in subtropical Psychotria brachyceras (Rubiaceae) similar to the general trends observed for the genus? [PDF]
Acta Botânica Brasílica, 2022 Distyly is a floral polymorphism that promotes cross-pollination through precise pollination. Psychotria is a mostly tropical genus of distylous Rubiaceae.

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,

Morphological Characteristics and Identification of Key Genes Regulating Distyly Morph in Primula vulgaris [PDF]
AgronomyThe Primula vulgaris, belonging to the genus Primula, is a typical distyly. The distyly is an important morphological feature in nature. However, there is a shortage of research on the causes of distyly formation and the associated genes that control ...
