Flavonoids are thought to function in the plant stress response and male fertility in some, but not all, species. We examined the effects of a self‐fertile chalcone synthase null allele, a, for the effects of heat and light stress on fertilization success and flower production in Ipomoea purpurea. Pollen recipients and pollen donors of both homozygous genotypes exhibit reduced fertilization success at high temperatures, indicating that high temperature acts as a stress‐lowering fertilization… 

Enhanced Reproductive Thermotolerance of the Tomato high pigment 2 Mutant Is Associated With Increased Accumulation of Flavonols in Pollen

It is strongly suggested that increased concentrations of pollen flavonols enhance pollen thermotolerance and reproductive success under heat stress conditions and may help frame the model for improving crop resilience to heat stress.

Enhanced reproductive thermotolerance is associated with increased accumulation of flavonols in pollen of the tomato high-pigment 2 mutant

The results strongly suggest that increased pollen flavonols content enhances pollen thermotolerance and reproductive success under heat stress conditions and may help frame the model for improving crop resilience to heat stress.

Genetic basis for a rare floral mutant in an Andean species of Solanaceae.

Comparison of anthocyanin gene sequences revealed a putative loss-of-function mutation, an 11 amino-acid deletion in dihydroflavonol 4-reductase (DFR), in the white morph, indicating that the structural mutation at Dfr underlies the rare white flower morph of I. calycinum.

Pleiotropic Effects of an Allele Producing White Flowers in Ipomoea purpurea

The notion that deleterious pleiotropy may influence the evolutionary trajectory of flower-color mutants is supported using white-flowered variants of the common morning glory.

The genetic basis of a flower color polymorphism in the common morning glory (Ipomoea purpurea).

It is determined that the anthocyanin biosynthetic gene flavonoid 3'-hydroxylase (f3'h) corresponds to the P locus, which determines whether flowers will be purple or pink, where purple is dominant to pink.

Low Inbreeding Depression and High Plasticity under Abiotic Stress in the Tall Morningglory (Ipomoea purpurea)

Results show very little inbreeding depression in this species, likely due to purging of deleterious alleles through repeated founder events in agricultural landscapes, and abiotic stress induced substantial plasticity in ecophysiological traits, reproductive traits, and biomass allocation.

Ecological significance of flavonoid accumulation in reproductive and vegetative tissues of silene littorea (caryophyllaceae)

It is found that UV light stimulated the production of both anthocyanins and flavones, especially these latter in photosynthetic tissues, which suggests that these compounds may have a key role as antioxidants and a minor role as light filters.

Flower color as a model system for studies of plant evo-devo

What is known about the ecological and molecular basis of anthocyanic flower color transitions in natural systems is reviewed and suggestions for future work on this trait are provided, suggesting that there is still much to be learned from the evolutionary development of flowercolor transitions in nature.

Acclimation to high temperature during pollen development

This work discusses whether pollen failure under high temperature might actually be an adaptation, and expression of heat stress-responsive genes shows unique patterns in developing pollen when compared to vegetative tissues that might explain the failure to withstand high temperatures.

Arctic Mustard Flower Color Polymorphism Controlled by Petal-Specific Downregulation at the Threshold of the Anthocyanin Biosynthetic Pathway

A widespread purple-white flower color polymorphism in the mustard Parrya nudicaulis spanning Alaska is described, suggesting the correlation of flower color and climate suggests that the loss of flavonoids in the petals alone may affect the tolerance of white-flowered individuals to colder environments.



Conditional Male Fertility in Chalcone Synthase-Deficient Petunia

The term conditional male fertility (CMF) is proposed to describe the state in which viable but flavonoid-deficient pollen does not function in self-crosses and is partially functional on wild-type stigmas.

Effects of a locus affecting floral pigmentation in Ipomoea purpurea on female fitness components.

The experiment described here was designed to determine whether other effects of the W locus may contribute an opposing selective advantage to the dark allele at this locus, which has been suggested to have a transmission advantage during mating because of the effect of flower color on pollinator behavior.

Flavonols : effects on fertility and fecundity

The finding that plant fecundity can be enhanced by manipulating the levels of flavonol aglycones (kaempferol) in stigmas was an unexpected bonus.


It is suggested that elevated selfing and enhanced success at pollen donation contribute to maintenance of the white allele in natural populations of morning glories.

Characterization of the chalcone synthase genes expressed in flowers of the common and Japanese morning glories.

The CHS genes encoding chalcone synthase for flavonoid biosynthesis in the common and Japanese morning glories comprise a multigene family and the CHS-D gene is the most abundantly expressed in the pigmented young flower buds and is primarily responsible for flower pigmentation.

The flavonoid biosynthetic pathway in plants: Function and evolution

Based on taxonomy and molecular analysis of gene expression patterns it is possible to deduce a putative sequence of acquisition of the different branches of the biosynthetic pathway and their regulators.

Molecular evolution of the chalcone synthase multigene family in the morning glory genome

It is concluded that recurrent gene duplication and subsequent differentiation is a major adaptive strategy in plant genome evolution.

The transposable element Tam1 of Antirrhinum majus is 17 kb long

The nivea locus of Antirrhinum majus encodes chalcone synthase, a key enzyme in anthocyanin biosynthesis, which causes genetic instability at this locus and leads to the variegated phenotype.

Flavonoids act as negative regulators of auxin transport in vivo in arabidopsis.

Analyses of auxin transport in the inflorescence and hypocotyl of independent tt4 alleles indicate that auxIn transport is elevated in plants with a tt 4 mutation, which is consistent with a role for flavonoids as endogenous regulators of Auxin transport.

Control of expression patterns of anthocyanin structural genes by two loci in the common morning glory

An evolutionary comparison of structural gene regulation in maize, snapdragons, petunias, and morning glories suggests that regulatory control of the anthocyanin pathway is evolutionarily labile.
