Homostyly of the Flowers of Buckwheat as a Morphological Manifestation of Sterility

Nature, 1946
BUCKWHEAT is a heterostylic plant, but as early as 1872, Muller described the occurrence in buckwheat, as in other heterostylic plants, of isolated homostylic flowers. In Primula and in flax, homostylic flowers were said to be morphologically aberrant but functional with increased self-fertility.

Heterostyly and homostyly inPentas lanceolata (Forsk.) Delf

Journal of Genetics, 1970
Heterodistyly inPentas lanceolat a (Forsk.) Delf., a species of the family Rubiaceae is described with measurements of style, anther, pollen grains and stigma papilla sizes. Homostyles with stamens and stigma at the same level in the same species is also reported.

Inheritance of flower homostyly of autogamous species Fagopyrum tataricum Gaertn. in interspecific crosses with heterostylous cross-pollinator F. cymosum Meisn.

Russian Agricultural Sciences, 2010
Inheritance of flower homostyly of self-fertile buckwheat species Fagopyrum tataricum have been studied in interspecific crosses. This species is homozygous for recessive allele s, an analogue of which determines long-styled (pin) type of flowers of heterostylous species F. cymosum. Interspecific differences are determined by a system of modifier genes

Comparative floral morphometrics of distyly and homostyly in three evolutionary lineages of Amsinckia (Boraginaceae)

Canadian Journal of Botany, 2001
Using three ancestor-descendant lineages of Amsinckia (Boraginaceae), we studied changes in floral morphology associated with evolution of the breeding system. Each lineage comprised a distylous ancestor and a homostylous descendant: (i) Amsinckia furcata Suksd. – Amsinckia vernicosa Hook. & Arn.; (ii) Amsinckia douglasiana A. DC.

Self‐pollination in buds and homostyly in Mussaenda shikokiana (Rubiaceae), a monomorphic species in a distylous clade

Journal of Systematics and Evolution, 2013
AbstractDistyly is a genetically controlled flower dimorphism. Most species in Mussaenda are distylous or functionally dioecious. Mussaenda shikokiana Makino consisted of one floral morph only in the populations studied in southern China. The present study aimed at illuminating the characteristics of floral monomorphism in M.

The genetics of homostyly in populations of Primula vulgaris

Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, 1960
Abstract Natural populations of primroses containing homostyles were found by Crosby (1940) near Sparkford, Somerset, and in the Chilterns. Homostyle frequencies up to 80% have often been recorded, but few populations containing higher frequencies have been found.

Heterostyly, homostyly, and long-distance dispersal of Menyanthes trifoliata to Greenland

Canadian Journal of Botany, 1987
An old report of homostyly in Menyanthes trifoliata L. in Greenland has been used as supporting evidence for the generally accepted hypothesis called Baker's law of long-distance dispersal. Measurements of flowers from both Denmark and Greenland throw considerable doubt on the existence of homostyly in this species.

[Homostyly as an efficient tool for development of homozygous lines of buckwheat (Fagopyrum esculentum Moench)].

TSitologiia i genetika, 2002
A genetic scheme of pollination in buckwheat Fagopyrum esculentum Moench and the specificity of work with its recessive mutations identified on the basis of heterostyly are considered. The possibility of obtaining a genetically determined donor of self-fertility on the basis of S1 allele controlling the development of the homostyle flower type in ...
