Genetic Causes and Genomic Consequences of Breakdown of Distyly in Linum trigynum. [PDF]
Mol Biol Evol, 2023 Distyly is an iconic floral polymorphism governed by a supergene, which promotes efficient pollen transfer and outcrossing through reciprocal differences in the position of sexual organs in flowers, often coupled with heteromorphic self-incompatibility ...

Characterization of PISTILLATA-like Genes and Their Promoters from the Distyly Fagopyrum esculentum [PDF]
Plants, 2022 Arabidopsis PISTILLATA (PI) encodes B-class MADS-box transcription factor (TF), and works together with APETALA3 (AP3) to specify petal and stamen identity. However, a small-scale gene duplication event of PI ortholog was observed in common buckwheat and

Genomic Patterns of Loss of Distyly and Polyploidization in Primroses. [PDF]
Mol Biol EvolTransitions from outcrossing to selfing and from diploidy to polyploidy often co-occur in plants, likely because the ability to produce selfed seed increases the likelihood of newly formed polyploids to become established.

Sources of Variation in Reciprocal Herkogamy in the Distyly Floral Syndrome of Linum tenue (Linaceae) [PDF]
INTERNATIONAL JOURNAL PLANT SCIENCES, 2023 Premise of research. Distyly is a floral polymorphism involving reciprocal herkogamy shaped by selection for pollen transfer efficiency. The variation of the floral organs involved in pollen transfer can be individually affected by environmental and ...

Bract size affects resource availability and fruit set in a hummingbird-pollinated plant with distyly polymorphism. [PDF]
Plant Biol (Stuttg)Plants can use non‐floral signals to advertise the presence of resources to pollinators. The distylous Psychotria poeppigiana (Rubiaceae) has reddish bracts with small yellow flowers.

Genomic analyses of the Linum distyly supergene reveal convergent evolution at the molecular level [PDF]
Current Biology, 2022 Supergenes govern multi-trait-balanced polymorphisms in a wide range of systems; however, our understanding of their origins and evolution remains incomplete.

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 ...

Developmental variation and the evolution of distyly in Hedyotis caerulea (Rubiaceae) [PDF]
SpringerPlus, 2013 The development of distyly is thought to arise from differential growth patterns in the pin and thrum morphs. However, few detailed studies exist on the early floral development of distylous flowers, and fewer still look at variation in these traits ...

Distyly and floral morphology of Psychotria cephalophora (Rubiaceae) on the oceanic Lanyu (Orchid) Island, Taiwan [PDF]
Botanical Studies, 2015 BackgroundPsychotria cephalophora Merr. (Rubiaceae), a shrub in oceanic islands of Taiwan and the Philippines, appears to be distylous, but distyly is usually rare on oceanic islands. To elucidate the functional breeding system of P.
