Cleistogamy—the production of open (chasmogamous—CH) and closed (cleistogamous—CL) floral forms by a species—is widespread among the angiosperms. While the CL flower is autogamous, the CH flower may provide a means for outcrossing. The term “cleistogamy” has also been used to describe other phenomena. A classification of types of cleistogamy is proposed. In this review, a restricted definition of cleistogamy is used to refer to species which show real floral dimorphisms, with divergent… Expand
The cleistogamous breeding system: A review of its frequency, evolution, and ecology in angiosperms
TLDR
The number of families, genera, and species in which cleistogamy occurs, and the number of times and potential reasons why cleistsogamy has evolved within angiosperms are quantified are estimated. Expand
Ecogenomics of cleistogamous and chasmogamous flowering: genome‐wide gene expression patterns from cross‐species microarray analysis in Cardamine kokaiensis (Brassicaceae)
TLDR
It is hypothesized that the interaction between the genetic network of the chilling response and that of floral development has been important in the evolution of cleistogamy in C. kokaiensis. Expand
Sex expression and breeding strategy in Commelina benghalensis L.
TLDR
The results of a series of experiments conducted to unravel the patterns of sex expression and reproductive output in a fascinating species with high variation in sexuality are described, indicating a mixed mating strategy in C. benghalensis. Expand
From herkogamy to cleistogamy--development of cleistogamy in periwinkle.
TLDR
Cleistogamy in periwinkle would facilitate in ensuring genetic purity, pollen containment, and seed production even in the absence of pollinators, and appears to be the first report on the development of cleistogamous plants in an allogamous species. Expand
Reproductive investment in a cleistogamous morph of Polygonum jucundum (Polygonaceae)
TLDR
The cleistogamous P. jucundum, compared with chasmogamous individuals, exhibited lower costs in male function, pollinator attraction and reward structure investment, and appears to be favourable for the plant reproduction under suboptimal conditions. Expand
Different Patterns of Floral Ontogeny in Dimorphic Flowers of Pseudostellaria heterophylla (Caryophyllaceae)
TLDR
The CL flower is not a developmental modification of the CH flower and that the four sepals of the CL flower may arise as a continuation of bracteole initiation, which is somewhat similar to that observed in the rest of the members of the Caryophyllaceae family. Expand
Gibberellins are involved but not sufficient to trigger a shift between chasmogamous-cleistogamous flower types in Viola pubescens1
TLDR
Increased levels of GAs in the floral buds appeared be related to flower type in the chasmogamous-cleistogamous mixed breeding system in V. pubescens, but exogenous application was not sufficient to induce an alteration in the type of flower produced. Expand
Analysis of microRNA reveals cleistogamous and chasmogamous floret divergence in dimorphic plant
TLDR
This is the first study on differential miRNA accumulation between CH and CL flowers and serves as a foundation to the future elucidation of regulatory mechanisms of miRNAs in the divergent development of CL and CH flowers in a single plant. Expand
Plasticity in the reproductive strategy of a clonal cleistogamous species, Pseudostellaria heterophylla
TLDR
The plasticity of reproductive strategies observed in P. heterophylla is proposed to be due to changes in the resource pool and resource allocation, and chasmogamous flower production in an individual plant was found to have little influence on its subsequent clonal propagation. Expand
Repeated evolution of a reproductive polyphenism in plants is strongly associated with bilateral flower symmetry
TLDR
Two of the largest datasets on floral symmetry and cleistogamy are combined and phylogenetic approaches are used to show that cleistsogamy is indeed disproportionately associated with zygomorphic flowers and that zygmorphic species are more likely to evolve cleistogsamy than actinomorphic species and provide support for the hypothesis that polyphenisms are favored when organisms encounter contrasting environments.

TLDR
Results support Lindman's concept of precocious development to explain the morphology of cleistogamous flowers in L. amplexicaule and change in floral morphology, as a function of inflorescence development are considered analogous to heteroblastic leaf development, a feature of progressively maturing vegetative shoot systems.

FLORAL POLYMORPHY AND AMPHIMICTIC BREEDING SYSTEMS IN RUELLIA CAROLINIENSIS (ACANTHACEAE)
TLDR
Observations and comparisons suggest that R. caroliniensis is a seasonal cleistogamic species, and it is proposed that the different breeding systems are the chief causes of the difficult taxonomic problem in the species. Expand

TLDR
A correlative approach is useful for suggesting relevant selective forces that might favor one breeding system over another, although incapable of proving which selective forces are the most important, it may serve to discredit hypotheses whose predictions are violated. Expand
CLEISTOGAMY IN SALPIGLOSSIS SINUATA
TLDR
Salpiglossis sinuata was first reported by Vilmorin (1894) who described such flowers without corolla, with short pistil, and with the capability of producing numerous seeds as "pseudo-cleistogamy" and Savelli later noticed (1927) that the expression of cleistsogamy in Salpigslossis species was unstable.

Hybridity, polyploidy and change in breeding system in a Ruellia hybrid
TLDR
The chromosome numbers in the six, out of 16, obligate cleistogamous taxa show that they are high polyploids, and this is perhaps the first case of origin by hybridization of a true breeding and fully fertile cleistogsamous taxon from two chasmogamous species. Expand

TLDR
The overall objective is to show that PIO's reflect the likelihood of sufficient pollen grains reaching each stigma to result in maximum seed set and suggest that PI O's are integrated with other facets of a plant's breeding system. Expand
