Andromonoecy and Floral Protandry of Oenanthe aquatica (Apiaceae)

Vestnik Tomskogo gosudarstvennogo universiteta. Biologiya, 2022
The paper studies the synflorescence structure and flowering biology of the biennial monocarpic wetland plant Oenanthe aquatica. This species has a set of adaptations to prevent self-pollination, including generation of a pseudanthium, andromonoecy, intra- and interfloral protandry, and a specific sequence of flowering within its umbels.

Climate adaptation and functional constraints drive pollen evolution in Apiales. [PDF]

New Phytol
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Size-dependent sex allocation in Solanum lycocarpum St. Hil. (Solanaceae)

Brazilian Journal of Biology, 2021
Resource allocation to reproduction can change depending on size, as predicted by the size-dependent sex allocation. This theory is based on the fact that small individuals will invest in the allocation of sex with lower cost of production, usually male ...

Evolution of crop phenotypic spaces through domestication. [PDF]

New Phytol
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

Sexual systems in the New Zealand angiosperm flora

New 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?

American 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 shrubTrevoa quinquenervia(Rhamnaceae) [PDF]

Botanical 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.

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

Annals 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

TAXON, 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).

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

American 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.
