Phosphoproteomic analysis of distylous Turnera subulata identifies pathways related to endoreduplication that correlate with reciprocal herkogamy [PDF]

American Journal of Botany
Abstract Premise A multi‐omic approach was used to explore proteins and networks hypothetically important for establishing filament dimorphisms in heterostylous Turnera subulata (Sm.) as an exploratory method to identify genes for future empirical research.

Does the occurence of homostyly necessarily accompany the breakdown of heteromorphic incompatibility system? [PDF]

Frontiers in Plant Science
IntroductionHeterostyly is a genetic polymorphism that facilitates precise pollen transfer through reciprocal herkogamy. The loss or variation of reciprocal herkogamy is usually accompanied by the breakdown of heteromorphic incompatibility system ...

Investigating morphological and biological reproductive traits in self-fertile and -infertile macadamia cultivars [PDF]

BMC Plant Biology
Self-fertility is a commercially valuable trait in crop species, enabling fruit set without reliance on pollinators or external pollinisers. In macadamia, most cultivars are self-infertile, though some can produce nuts with self-pollen.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen-rewarding Caribbean bloodwort. [PDF]

Am J Bot
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Variation in tolerance to heterospecific pollen from a non-native congener depends on co-existence history of maternal and paternal source populations. [PDF]

Am J Bot
Abstract Premise Plants in sympatric populations with congeners may have evolved tolerance to the negative effects of heterospecific pollen (HP) through selection on female or male reproductive traits. If so, then the degree of HP tolerance may vary depending on the co‐existence history of the maternal and paternal plant source populations.

Investigating the effects of fire on pollinator-dependent distyly polymorphism. [PDF]

Plant Biol (Stuttg)
While fire causes some morphological changes in pollinator‐dependent distylous flowers, most traits related to attraction, reward, and stigma‐anther reciprocity remain unaffected, ensuring intermorph pollen transfer and maintaining the floral polymorphism.

Floral Color Change Mediated by Pollen Input-Output and Its Manipulation of Pollinator Foraging Behavior in Heterostylous Plant <i>Arnebia guttata</i> (Boraginaceae). [PDF]

Ecol Evol
The inducement, functions of flower color change (FCC) and its ecological effects have been studied by controlling pollination, accurate statistics of pollen transfer and visiting behavior in a typical distylous species. The results showed that limiting pollen input–output can delay fading time of spots, adding fake spots to old flowers can improve ...

Comparative Proteomic Analysis of Self-Compatible <i>Turnera</i> Mutants Suggests <i>Glutathione S-Transferase 8</i> Is Involved in Overcoming S-Morph Female Self-Incompatibility Response. [PDF]

Plant Direct
ABSTRACT Distyly is a reproductive system, characterized by the presence of two floral morphs, which promotes outcrossing via physical and biochemical means. In distylous Turnera, the mating type of the S‐morph is determined by two genes: YUC6 (male) and BAHD (female).

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

FlowerMate: Multidimensional reciprocity and inaccuracy indices for style-polymorphic plant populations. [PDF]

Appl Plant Sci
Abstract Premise Heterostyly in plants promotes pollen transfer between floral morphs, because female and male sex organs are located at roughly reciprocal heights within the flowers of each morph. Reciprocity indices, which assess the one‐dimensional variation in the height of sex organs, are used to define the phenotypic structure of heterostyly in ...
