Fitness Effects of Somatic Mutations Accumulating during Vegetative Growth

open access: yes, 2022
The unique life form of plants promotes the accumulation of somatic mutations that can be passed to offspring in the next generation, because the same meristem cells responsible for vegetative growth also generate gametes for sexual reproduction. However,

A comparative study on the reproductive success of two rewarding Habenaria species (Orchidaceae) occurring in roadside verge habitats

open access: yesBMC Plant Biology, 2021
Background Most orchid species have been shown to be severely pollination limited, and the factors affecting reproductive success have been widely studied. However, the factors determining the reproductive success vary from species to species.

DataSheet_1_Preventing self-fertilization: Insights from Ziziphus species.pdf

open access: yes, 2023
The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Nolana balsamiflua (Gaudich.) Mesa (Solanaceae), un arbusto vulnerable del desierto de Atacama dependiente de polinizadores para producir semillas

open access: yesGayana: Botanica, 2019
Pollinator-dependency for reproduction is of great importance for plants. We evaluated the breeding system of Nolana balsamiflua, a threatened endemic shrub of the Atacama Desert, performing four pollination trials.

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

open access: yesNew Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Internal geitonogamy [PDF]

open access: yes, 2001
Geitonogamy (the pollination between flowers on the same plant) has important implications for sex-allocation theory, the evolution of dioecy and other issues in evolutionary biology. Internal geitonogamy is a unique self-pollination system that occurs

First report on the pollination of Neotinea maculata (Orchidaceae) by minor worker ants of the Temnothorax exilis group (Hymenoptera: Formicidae)

open access: yesMediterranean Botany, 2021
Ants commonly visit flowers seeking for food resources such as nectar. However, only eight species of orchids are known for having an effective pollinaria removal by ants.

The Function of the Partially‐Opened Spathe of Pinellia pedatisecta (Araceae) as a Pitfall Pollinator Trap

open access: yesPlant Species Biology, Volume 41, Issue 4, July 2026.
Pinellia pedatisecta has a simplified inflorescence structure, compared to its congeners with highly specialized trap pollination systems. However, our study suggests that P. pedatisecta also captures and releases pollinating insects by the spathe movement during flowering season.

Separated Sexes, Shared Consequences: Disentangling Predictors of Genetic Diversity in Dioecious Angiosperms

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluates the factors influencing intrapopulation genetic diversity in dioecious flowering plants by integrating genetic and ecological data from studies published up to 2025. We show that pollination mode, endemism, and conservation status significantly shape genetic diversity patterns, with endemic and threatened species exhibiting the ...
