Occurrence and Prevention of Delayed Autonomous Selfing in Salvia umbratica (Lamiaceae)

open access: yesFrontiers in Plant Science, 2021
Delayed autonomous selfing (DAS) provides reproductive assurance under conditions of pollinator and/or pollen-limitation. Few plant species have been investigated to determine if DAS is terminated when a flower is sufficiently pollinated by a pollen ...

Diet alters delayed selfing, inbreeding depression, and reproductive senescence in a freshwater snail. [PDF]

open access: yesEcol Evol, 2014
Reproductive success is a critical fitness attribute that is directly influenced by resource availability. Here, we investigate the effects of diet-based resource availability on three interrelated aspects of reproductive success: a change in mating ...

Pollinator scarcity drives the shift to delayed selfing in Himalayan mayapple Podophyllum hexandrum (Berberidaceae) [PDF]

open access: yesAoB Plants, 2013
American mayapple and Himalayan mayapple are a pair of sister species with disjunct distribution between eastern Asia and eastern North America, which the former was considered to be self-incompatible but the later to be self-compatible.

The best of both worlds? A review of delayed selfing in flowering plants [PDF]

open access: yesAmerican-Eurasian journal of botany, 2018
PREMISE OF STUDY: In a seminal body of theory, Lloyd showed that the fitness consequences of selfing will depend on its timing in anthesis. Selfing that occurs after opportunities for outcrossing or pollen dispersal can provide reproductive assurance ...

Differences in pollination syndromes and the frequency of autonomous delayed selfing between co-flowering Hibiscus aponeurus (Sprague and Hutch) and H. flavifolius (Ulbr) from Kenya

open access: yesJournal of Pollination Ecology, 2018
Delayed autonomous selfing offers a mechanism for seed production when pollination levels are low or unpredictable. At Mpala Research Centre (MRC) in Kenya, we examined the relationships between floral attraction, insect visitation, and delayed ...

Stamens enclosed by petals in Berchemia (Rhamnaceae): a unique mechanism for pollen presentation [PDF]

open access: yesFrontiers in Plant Science
IntroductionPollen is usually presented by the anthers after maturity. However, in some plants, pollen is presented to pollinators on other floral structures (other than the anthers), or via particular expulsion mechanisms, resulting in secondary pollen ...

Chromosome-level genome assembly of the threatened ornamental plant Hibiscus yunnanensis [PDF]

open access: yesScientific Data
Hibiscus yunnanensis S.Y. Hu is an endangered species of the genus Hibiscus (Malvaceae), which has high potential economic value. However, the absence of a high-quality reference genome impedes the study of the ecology and molecular biology of H ...

Late-acting self-incompatible system, preferential allogamy and delayed selfing in the heteromorphic invasive populations of Ludwigia grandiflora subsp. hexapetala

open access: yesbioRxiv, 2021
Breeding system influences local population genetic structure, effective size, offspring fitness and functional variation. Determining the respective importance of self- and cross-fertilization in hermaphroditic flowering plants is thus important to ...
