Coleopteran Pollinators of Annonaceae in the Brazilian Cerrado—A Review

Diversity, 2021
The evolutionary trajectories of insects and angiosperms appear to be intimately interconnected. Increases in the diversity of phytophagous beetles and angiosperms co-occur in the Mesozoic fossil record, and there is fossil evidence of pollinivory and ...

Quantitative importance of staminodes for female reproductive success in Parnassia palustris under contrasting environmental conditions. [PDF]

, 2003
The five sterile stamens, or staminodes, in Parnassia palustris act both as false and as true nectaries. They attract pollinators with their conspicuous, but non-rewarding tips, and also produce nectar at the base.

Leaf energy balance modelling as a tool to infer habitat preference in the early angiosperms [PDF]

, 2015
Despite more than a century of research, some key aspects of habitat preference and ecology of the earliest angiosperms remain poorly constrained. Proposed growth ecology has varied from opportunistic weedy species growing in full sun to slow-growing ...

A mega-phylogeny of the Annonaceae: taxonomic placement of five enigmatic genera and support for a new tribe, Phoenicantheae

Scientific Reports, 2017
The Annonaceae, the largest family in the early-divergent order Magnoliales, comprises 107 genera and c. 2,400 species. Previous molecular phylogenetic studies targeting different taxa have generated large quantities of partially overlapping DNA sequence

Phylogenetic analysis of Magnoliales and Myristicaceae based on multiple data sets: implications for character evolution [PDF]

Botanical Journal of the Linnean Society, 2003
Magnoliales, consisting of six families of tropical to warm-temperate woody angiosperms, were long considered the most archaic order of flowering plants, but molecular analyses nest them among other eumagnoliids. Based on separate and combined analyses of a morphological matrix (115 characters) and multiple molecular data sets (seven variable ...

Pollen development in Mill. (Annonaceae). Implications for the evolution of aggregated pollen [PDF]

, 2009
In most flowering plants, pollen is dispersed as monads. However, aggregated pollen shedding in groups of four or more pollen grains has arisen independently several times during angiosperm evolution.

Reevaluation of the cox1 group I intron in Araceae and angiosperms indicates a history dominated by loss rather than horizontal transfer [PDF]

, 2008
The origin and modes of transmission of introns remain matters of much debate. Previous studies of the group I intron in the angiosperm cox1 gene inferred frequent angiosperm-to-angiosperm horizontal transmission of the intron from apparent incongruence ...

Comparative insights into molecular pathways influencing germline development in early‐divergent angiosperms

The Plant Journal, Volume 125, Issue 2, January 2026.
SUMMARY The molecular and genetic mechanisms regulating female germline development remain largely unknown in basal and early‐divergent angiosperms. This contrasts with recent progress in model eudicots such as Arabidopsis thaliana and monocots, such as rice, barley, and maize. In this study, we investigate the genetic pathway governing female germline

The Genome of Phoebe zhennan (Lauraceae) and Comparative Genomics of Phoebe 楠木(樟科)基因组与楠属植物比较基因组学研究

Integrative Conservation, Volume 4, Issue 4, Page 584-599, December 2025.
Phoebe zhennan is a Chinese endemic and valuable timber species of Phoebe (Lauraceae). We present a chromosome‐level genome assembly of P. zhennan. Our research provides novel insights into the genome evolution of Phoebe, including whole‐genome duplication, phylogenetic relationships of magnoliids, and key MYB regulatory genes involved in lignin ...

Flower visitors to cherimoya, Annona cherimola (Magnoliales: Annonaceae) in Japan

Applied Entomology and Zoology, 2005
The cherimoya is an orchard tree that is not pollinated by bees. To identify likely pollinators, and to describe community diversity, we surveyed flower visitors at four sites in Wakayama and Mie prefectures, and found 569 individuals from 31 species of arthropods. Two of these species were arachnid and the others were insects.
