Evolutionarily Stable Cleistogamy

Botanical Journal of the Linnean Society
Abstract Cleistogamy, the production of closed flowers providing obligatory selfed seeds, has evolved repeatedly in more than 50 botanical families. Usually associated with chasmogamy, open flowers producing potentially outcrossed seeds in various proportion is an iconic example of mixed self-fertilization.Here, I develop an ...

An alternative mechanism for cleistogamy in barley [PDF]

Theoretical and Applied Genetics, 2013
Cleistogamy in barley is genetically determined by the presence of the recessive allele cly1, but the dominant allele at the linked locus Cly2 is epistatic over cly1. Although the molecular basis for cly1 action is well understood, that of Cly2 is not.

Expression variation of Viola APETALA3 orthologous genes is correlated with chasmogamous and cleistogamous flower development [PDF]

BMC Plant Biology
Background Viola philippica and V. prionantha develop chasmogamous (CH) flowers under ≤ 12-h daylight conditions and cleistogamous (CL) flowers under long daylight (> 12-h daylight) conditions (LD), whereas V.

Transgenerational effects of stress on reproduction strategy in the mixed mating plant Lamium amplexicaule [PDF]

BMC Plant Biology
Background The theory of Condition Dependent Sex predicts that – everything else being equal – less fit individuals would outcross at higher rates compared with fitter ones.

Auxin-related regulation of barley floral organ fate: genetic and phenotypic insights from tweaky spike mutants. [PDF]

New Phytol
Inflorescence/floret phenotypes of tweaky spike (tw) barley (Hordeum vulgare) mutants and their respective WT backgrounds. Summary Mutant‐based research is a cornerstone for elucidating gene function in barley (Hordeum vulgare) and other cereals. In this study, we exploited a unique collection of barley tweaky spike (tw) mutants to identify the locus ...

Population genomic signatures of founding events in autonomously self-fertilizing plants: a test with Impatiens capensis. [PDF]

New Phytol
Summary Autonomously self‐fertilizing plants possess disproportionate abilities to found populations. Viewed from the metapopulation perspective, founding events should be frequent in such plants, but the intensity and timing of bottlenecks and recovery should vary among populations.

Genetic and Linkage Analysis of Cleistogamy in Soybean [PDF]

Journal of Heredity, 2001
Early maturing cultivars of soybean [Glycine max (L.) Merr.] native to the shores of the Sea of Okhotsk (Sakhalin and Kuril Islands) and eastern Hokkaido (northern Japan) have been used in breeding for chilling tolerance. These cultivars have a strong tendency to produce cleistogamous flowers throughout their blooming period.

Good to the Last Drop? Nectar Depletion by Insect Pollinators Varies Among Plant Species and Through Time. [PDF]

Ecol Evol
Understanding how pollinators compete for available floral resources (nectar, pollen, etc.) across time is poorly studied, especially in the western hemisphere. To address this knowledge gap, we measured nectar availability and subsequent depletion as a proxy for resource competition intensity among pollinators in an early successional old field ...

From Herkogamy to Cleistogamy - Development of Cleistogamy in Periwinkle [PDF]

Journal of Heredity, 2012
Periwinkle (Catharanthus roseus [L.] G. Don), an important medicinal plant, is an allogamous species in which the stigma is below the anthers. The receptive portion is at the base of the stigmatic head and thus automatic intra-flower self-pollination is excluded. The structure of the flower is of typical reverse herkogamy and pollination occurs through
