Repeated Evolution of Dioecy from Monoecy in Siparunaceae (Laurales) [PDF]

Systematic Biology, 2001
Siparunaceae comprise Glossocalyx with one species in West Africa and Siparuna with 65 species in the neotropics; all have unisexual flowers, and 15 species are monoecious, 50 dioecious. Parsimony and maximum likelihood analyses of combined nuclear ribosomal ITS and chloroplast trnL-trnF intergenic spacer sequences yielded almost identical topologies ...

Contents and Recovery of Gibberellins in Monoecious and Gynoecious Cucumber Plants [PDF]

Plant Physiology, 1968
Diffusates from seedlings and root exudates from 6-week-old plants of a monoecious line of cucumber, Cucumis sativus L., contained considerably higher levels of gibberellin-(GA-) like substances than did those from plants of an isogenic gynoecious line.

Evolutionary shifts to gynomonoecy correlate with changes in capitulum architecture in South African Helichrysum (Asteraceae)

New Phytologist, EarlyView.
Representative South African Helichrysum species illustrating variation in capitulum size. Summary Gynomonoecy has evolved repeatedly in Asteraceae, suggesting selective advantages for species whose capitula combine pistillate and bisexual flowers. Theories invoking conspicuous peripheral flowers and achene heteromorphism do not account for gynomonoecy

All pieces together now? A phylogenomic analysis and tribe‐level classification of the heterogeneous family Plantaginaceae

TAXON, Volume 75, Issue 4, August 2026.
Abstract The plant family Plantaginaceae comprises approximately 2100 species in 106 genera, representing around 1% of all eudicots. The current circumscription of the family has been established in recent decades based on insights from DNA‐based phylogenetic analyses, which have united genera previously considered unrelated.

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

New Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Molecular Mechanism Underlying Derepressed Male Production in Hexaploid Persimmon

Frontiers in Plant Science, 2020
Sex expression in plants is often flexible and contributes to the maintenance of genetic diversity within a species. In diploid persimmons (the genus Diospyros), the sexuality is controlled by the Y chromosome-encoded small-RNA gene, OGI, and its ...

Phytohormone and integrated mRNA and miRNA transcriptome analyses and differentiation of male between hermaphroditic floral buds of andromonoecious Diospyros kaki Thunb

BMC Genomics, 2021
Background Persimmon (Diospyros kaki Thunb.) has various labile sex types, and studying its sex differentiation can improve breeding efficiency. However, studies on sexual regulation patterns in persimmon have focused mainly on monoecy and dioecy ...

Manifold limits on seed production by individual flowering plants

American Journal of Botany, Volume 113, Issue 5, May 2026.
Abstract Premise Historically, angiosperm seed production has been considered to be either pollen or resource limited. However, seed production involves more than pollen and seed resources and typically involves multiple ovules in multiple flowers. Therefore, various constraints may act simultaneously. Methods Proportional components of seed production
