The Development of Heterostyly
1992Heterostyly is a genetic polymorphism in which the two (distyly) or three (tristyly) mating types in a population differ in floral morphology. The principal feature that distinguishes the floral morphs is that they differ in stigma and anther heights. The sex organs are reciprocally positioned with anthers in flowers of one morph at the same level as ...

Reproduction: The genetic basis of heterostyly
Nature Plants, 2016Two recent studies revealed the genetic architecture of the long fascinating heterostyly in Primula and that the absence of a CYPT gene determines the long style morph.

Evolution and Function of Heterostyly
Trends in Ecology & Evolution, 1992A century of research on heterostylous plants has passed since the publication of Charles Darwin's book "The Different Forms of Flowers on Plants of the Same Species" in 1877 summarizing his extensive observations and experiments on these complex breeding systems involving genetic polymorphisms of floral sex organs.

The evolution and adaptive significance of heterostyly
Trends in Ecology & Evolution, 1990The origin and adaptive significance of heterostylous breeding systems have fascinated evolutionary biologists since Darwin's early work on the subject. Models of the evolution of heterostyly differ in the emphasis given to different selective forces and in the sequence in which the physiological and morphological components of the polymorphism are ...

The nonreciprocal heterostyly and heterotypic self-incompatibility of Ceratostigma willmottianum
Journal of Plant Research, 2021Ceratostigma willmottianum (Plumbaginaceae) is a perennial herb native to China. Many species of Plumbaginaceae have been reported to exhibit heterostyly. Determining the functional breeding system of C. willmottianum can improve our understanding of the reproductive ecology of heterostylous plants.

Heterostyly and the possibility of its breakdown by polyploidization
Plant Species Biology, 2012Abstract Heterostyly is a genetically controlled sexual polymorphism promoting outcrossing by animal pollinators. The occurrence of heterostyly in angiosperms was investigated, and 199 genera in 28 families in 15 orders were recognized as taxa that contain heterostylous species.

Heterostyly in the Canarian endemic Jasminum odoratissimum (Oleaceae)
Nordic Journal of Botany, 2003Jasminum odoratissimum is a Madeira and Canary Islands endemic showing classic heterostyly, i.e. with long‐styled flowers with anthers at a low level in the corolla tube and short‐styled flowers with anthers at a high level in the corolla tube. Short‐styled flowers have large pollen, whereas long‐styled flowers have small pollen.

Historical Perspectives on Heterostyly
1992Heterostyly was recognized as a morphological feature of certain groups of flowering plants as early as the 16th century, when it was reputedly noted in Primula by Clusius (van Dijk 1943). Few, if any, attempts were made to interpret the adaptive significance of this floral heteromorphism until Charles Darwin and Friedrich Hildebrand studied the ...

Heterostyly inBiophytum sensitivum DC
Journal of Genetics, 1964Heterostylism inBiophytum sensitivum DC. is described with measurements of style and anther lengths and pollen grain diameters. The fertility of different crosses is compared. One type of illegtimate union is moderately fertile.
