Early consequences of allopolyploidy alter floral evolution in Nicotiana (Solanaceae) [PDF]

BMC Plant Biology, 2019
Background Polyploidy has played a major role in angiosperm evolution. Previous studies have examined polyploid phenotypes in comparison to their extant progenitors, but not in context of predicted progenitor phenotypes at allopolyploid origin.

Diverse floral scents in Malagasy Bulbophyllum evolve in a bounded fashion [PDF]

Frontiers in Plant Science
Floral scent is a fundamental feature in angiosperm pollination, reproductive isolation, and speciation. However, little is known about the neutral or selective processes shaping long-term patterns of floral scent evolution within particular lineages ...

Within-species floral evolution reveals convergence in adaptive walks during incipient pollinator shift [PDF]

Nature Communications
Understanding how evolution proceeds from molecules to organisms to interactions requires integrative studies spanning biological levels. Linking phenotypes with associated genes and fitness illuminates how adaptive walks move organisms between fitness ...

Floral evolution of Philodendron subgenus Meconostigma (Araceae). [PDF]

PLoS ONE, 2014
Elucidating the evolutionary patterns of flower and inflorescence structure is pivotal to understanding the phylogenetic relationships of Angiosperms as a whole. The inflorescence morphology and anatomy of Philodendron subgenus Meconostigma, belonging to

Convergence without divergence in North American red-flowering Silene

Frontiers in Plant Science, 2022
Combinations of correlated floral traits have arisen repeatedly across angiosperms through convergent evolution in response to pollinator selection to optimize reproduction.

Evolution and Classification of Musaceae Based on Male Floral Morphology

Plants, 2023
Classification of the banana family (Musaceae) into three genera, Musa, Ensete and Musella, and infrageneric ranking are still ambiguous. Within the genus Musa, five formerly separated sections were recently merged into sections Musa and Callimusa based ...

Macroevolution of Flower Color Patterning: Biased Transition Rates and Correlated Evolution with Flower Size

Frontiers in Plant Science, 2020
Floral pigmentation patterns can both mediate plant-pollinator interactions and modify the abiotic environment of reproductive structures. To date, there have been no inquiries into the rate and directionality of macroevolutionary transitions between ...

Ecological interactions shape the evolution of flower color in communities across a temperate biodiversity hotspot

Evolution Letters, 2021
Processes driving the divergence of floral traits may be integral to the extraordinary richness of flowering plants and the assembly of diverse plant communities.

Pollinator-Mediated Selection on Floral Traits of Primula tibetica Differs Between Sites With Different Soil Water Contents and Among Different Levels of Nutrient Availability

Frontiers in Plant Science, 2022
Abiotic environmental factors are predicted to affect plant traits and the intensity of plant-pollinator interactions. However, knowledge of their potential effects on pollinator-mediated selection on floral traits is still limited.

Perianth Phyllotaxis Is Polymorphic in the Basal Eudicot Anemone and Eranthis Species

Frontiers in Ecology and Evolution, 2020
Floral organs are clade-specifically arranged to either spiral or whorled (concentric circles) phyllotaxis. The basic number (merosity) of perianth organs within a whorl is limited to three in most monocots and to four or five in most eudicots.
