Repeated evolution of self-compatibility for reproductive assurance [PDF]

open access: yesNature Communications, 2018
Mating-type switching enables self-compatible reproduction in fungi, but switching ability is variable even within species. Here, the authors find de novo evolution of switching genotypes in experimentally evolved fission yeast populations and show a ...

Reproductive Assurance Maintains Red-Flowered Plants of Lysimachia arvensis in Mediterranean Populations Despite Inbreeding Depression [PDF]

open access: yesFrontiers in Plant Science, 2020
Flower color polymorphism, an infrequent but phylogenetically widespread condition in plants, is captivating because it can only be maintained under a few selective regimes but also because it can drive intra-morph assortative mating and promote ...

Reproductive assurance drives transitions to self-fertilization in experimental Caenorhabditis elegans. [PDF]

open access: yesBMC Biol, 2014
Evolutionary transitions from outcrossing between individuals to selfing are partly responsible for the great diversity of animal and plant reproduction systems.

Reproductive assurance weakens pollinator-mediated selection on flower size in an annual mixed-mating species. [PDF]

open access: yesAnn Bot, 2019
BACKGROUND AND AIMS In animal-pollinated plants, direct and indirect selection for large and small flowers in predominantly outcrossing and selfing species, respectively, is a common consequence of pollen limitation (PL).

Reproductive assurance in three Neotropical species of Podostemaceae: strategies of self-pollination and the first report of apomixis1

open access: yesHoehnea, 2020
(Reproductive assurance in three Neotropical species of Podostemaceae: strategies of self-pollination and the first report of apomixis). The aspects of reproductive assurance of the Lophogyne lacunosa (Gardner) C.P.Bove & C.T.Philbrick, Podostemum ...

High lifetime inbreeding depression counteracts the reproductive assurance benefit of selfing in a mass-flowering shrub. [PDF]

open access: yesBMC Evol Biol, 2014
BackgroundDecreases in mate and/or pollinator availability would be expected to affect the selective pressure on plant mating systems. An increase in self-fertilization may evolve to compensate for the negative effects of pollination failure.

Observations of Simultaneous Sperm Release and Larval Planulation Suggest Reproductive Assurance in the Coral Pocillopora acuta

open access: yesFrontiers in Marine Science, 2019
Despite being an extensively studied group of corals, the reproductive biology of the scleractinian genus Pocillopora remains a mystery. Pocillopora acuta has been proposed to exhibit a mixed reproductive mode, sexually producing gametes (sperm and eggs)

Pollinator-mediated self-pollination and reproductive assurance in an isolated tree of Magnolia grandiflora L.

open access: yesEcological Processes, 2020
Background The ability to produce seeds when pollinators or potential mates are scarce is one of the principal advantages of self-pollination in flowering plants.

Characteristics of Floral Volatiles and Their Effects on Attracting Pollinating Insects in Three Bidens Species with Sympatric Distribution [PDF]

open access: yesBiology
The transition from outcrossing to self-pollination is an evolutionary process in angiosperms. However, the changes in floral volatile composition during this process and their impacts on the behavior of pollinators are poorly understood. Therefore, this

Unlocking tropical adaptation: novel flowering time genes implicate JA and ROS signaling in maize [PDF]

open access: yesBMC Plant Biology
Background Tropical maize germplasm offers a valuable resource of genetic diversity for temperate maize breeding programs but its utilization is often constrained by poor flowering adaptation under long-day photoperiods, which act as a major adaptive ...
