the carpels, thus fulfilling one of the principal theoretical reasons for the evolution
of syncarpy, which are explained in greater detail below. The major evolutionary
advantage of syncarpy is probably to allow a regular repartition of pollen tubes ...

Early Events in Monocot Evolution
phylogenetic studies (Potter et al., 2007; Horn, 2009) indicate multiple origins of
syncarpy derived from apocarpy (i.e. from secondary apocarpy, if the scenario
outlined above is accepted). In the case of Rosaceae, subsequent reversals to ...

Developmental Genetics of the Flower: Advances in Botanical ...
evolutionary progressions in gynoecium evolution: from gymnospermy to
angiospermy and, in addition, from apocarpy to syncarpy (Fig. 11). The two
phenomena, angiospermy and syncarpy, have sometimes erroneously been
conflated.

Advances in Botanical Research
Another potentially important advantage of syncarpy results from the enhanced
competition that this produces between pollen tubes: an effect which may select
for vigorous male parents. Syncarpy also allows for the production of larger fruits,
...

Flowers on the Tree of Life
The type of syncarpy varies between eusyncarpous (carpels fused at the centre
of the gynoecium) in Aristolochiaceae and paracarpous (carpels fused into a
unilocular gynoecium with parietal placentation) in Canellaceae, Takhtajania, ...

Morphology of Flowers and Inflorescences
In all such cases therefore a "pseudo-syncarpy" is present, and moreover in the
superior ovary of Nuphar this is abandoned in the ripe fruit, when the external
coat of axial material as well as the tissue beside and between the carpels is
shed ...

Diversity and Evolutionary Biology of Tropical Flowers
2.4.6 Evolutionary aspects There are two major evolutionary trends in the
angiosperm gynoe- cium among a multitude of 'oscillating' (minor) evolutionary
changes. The first is the advent of syncarpy from apocarpy; the second, the
evolution of ...

The Molecular Biology and Biochemistry of Fruit Ripening
Syncarpy occurs in 83% of extant angiosperm species, and has been interpreted
as facilitating pollen tube competition and thus fitness (Endress, 1982); syncarpy
has arisen in both the monocots and the eudicots independently (Endress, ...

The Character Concept in Evolutionary Biology
Syncarpy In basal angiosperms the carpels of a flower are free from each other or
there is only one carpel in a flower. However, in the majority of the angiosperms
as a whole, the carpels of each flower are congenitally united. This is true for ...

It is possible for a single carpel to have been derived directly by reduction from
syncarpy. It is also possible that a single carpel has been derived by reduction
from apocarpy (e.g., in Zosteraceae and Posidoniaceae). Three origins of a
single ...
