Andromonoecy and developmental plasticity in Chaerophyllum bulbosum (Apiaceae–Apioideae) [PDF]

open access: yesAnnals of Botany, 2013
Andromonoecy, the presence of hermaphrodite and male flowers in the same individual, is genetically fixed or induced, e.g. by fruit set. Little is known about the forces triggering andromonoecy in the Apiaceae. In the present study, a natural population of the protandrous Chaerophyllum bulbosum was investigated to elucidate architectural constraints ...

Sexual systems in the New Zealand angiosperm flora

open access: yesNew Zealand Journal of Botany, Volume 61, Issue 4, Page 201-231, December 2023., 2023
ABSTRACT We present data on sexual systems and associated traits in the New Zealand angiosperm flora and discuss reasons for the anomalously high levels of gender dimorphism in the flora, and the low levels of monoecy in woody species. Along with Hawai'i and New Caledonia, New Zealand has exceptionally high levels of gender dimorphism (19.5% of ...

Adaptive function of duodichogamy: Why do chestnut trees have two pollen emission phases?

open access: yesAmerican Journal of Botany, Volume 110, Issue 8, August 2023., 2023
Abstract Premise Intersexual mating facilitation in flowering plants has been largely underexplored. Duodichogamy is a rare flowering system in which individual plants flower in the sequence male‐female‐male. We studied the adaptive advantages of this flowering system using chestnuts (Castanea spp., Fagaceae) as models.

Reproductive biology of the andromonoecious Cucumis melo subsp. agrestis (Cucurbitaceae) [PDF]

open access: yesAnnals of Botany, 2009
Cucumis melo subsp. agrestis (Cucurbitaceae) is cultivated in many African regions for its edible kernels used as a soup thickener. The plant, an annual, andromonoecious, trailing-vine species, is of high social, cultural and economic value for local communities.

Morphological trait evolution in Solanum (Solanaceae): Evolutionary lability of key taxonomic characters

open access: yesTAXON, Volume 72, Issue 4, Page 811-847, August 2023., 2023
Abstract Solanum is one of the world's largest and economically most important plant genera, including 1245 currently accepted species and several major and minor crops (e.g., tomato, potato, brinjal eggplant, scarlet eggplant, Gboma eggplant, lulo, and pepino).

Andromonoecy functional through heterostyly and large carpenter bees as principal pollinators in Solanum carolinense L. (Solanaceae)

open access: yesJournal of Threatened Taxa, 2023
Solanum carolinense is a perennial shrubby weed. In this species, andromonoecy is functional through heterostyly represented by the production of long, semi-long, medium, & short-styled flower types and another flower type lacking style & stigma ...

Reproductive biology of the andromonoecious shrubTrevoa quinquenervia(Rhamnaceae) [PDF]

open access: yesBotanical Journal of the Linnean Society, 1998
Abstract Various aspects of the reproductive biology of the andromonoecious shrub Trevoa quinquenervia Gill. & Hook. were studied in a population located in central Chile. Flowering extends from mid August to the end of December. The small, white, entomophilous flowers are incompletely protandrous and last c . 5 days.

Differential reward in “male” versus “female” pollen of functionally dioecious Solanum

open access: yesAmerican Journal of Botany, Volume 108, Issue 11, Page 2282-2293, November 2021., 2021
Abstract Premise Five to six percent of angiosperm species exhibit a dioecious sexual system, with unisexual “male” or “female” flowers borne on separate plants. The consequent need for inter‐individual pollen exchange is a special challenge for taxa where pollen is the sole pollinator reward.

Phylogenomics of the tropical plant family Ochnaceae using targeted enrichment of nuclear genes and 250+ taxa

open access: yesTAXON, Volume 70, Issue 1, Page 48-71, February 2021., 2021
Abstract Targeted capture of nuclear genes increasingly contributes to unravelling phylogenetic relationships that hitherto remained unresolved because of limitations of traditional Sanger sequencing. In particular, the study of tropical plant families has been compromised because they often rely on highly degraded DNA obtained from herbarium specimens.

Andromonoecy in Solanum marginatum

open access: yesBotanical Gazette, 1981
Solanum marginatum is andromonoecious, with long-styled hermaphrodite flowers and medium- or shortstyled female sterile flowers which produce fertile pollen. The morphology of the three floral types is compared. The female sterile type is determined prior to the stage at which the flower buds are visible.
