Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Molecular and Morphological Phylogenetic Analyses of New World Cycad Beetles: What They Reveal about Cycad Evolution in the New World

Diversity, 2018
Two major lineages of beetles inhabit cycad cones in the New World: weevils (Curculionoidea) in the subtribe Allocorynina, including the genera Notorhopalotria Tang and O’Brien, Parallocorynus Voss, Protocorynus O’Brien and Tang and ...

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

Journal of Systematics and Evolution, Volume 64, Issue 2, Page 295-312, March 2026.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.

Missouri Botanical Garden's cycad collection: A journey through time

Plant Species Biology, Volume 40, Issue 6, Page 607-624, November 2025.
This article summarizes the history of the Missouri Botanical Garden's extensive cycad collection. Some of the specimens currently housed in the living collections date back well over 100 years. Cycads continue to face a myriad of threats in the wild, and their conservation in ex situ collections is of critical importance to assist in their survival ...

Endemic plant relict [PDF]

, 2012
Endemi su organizmi koji žive na određenom ograničenom geografskom području i nigdje drugdje na svijetu. Prema starosti razlikujemo reliktne endeme (paleoendeme) i neoendeme.

A first characterization of the leaflet endophytic prokaryotic community in Dioon cycads

Plant Species Biology, Volume 40, Issue 6, Page 547-555, November 2025.
This study presents the first characterization of leaflet endophytic prokaryotic communities in Mexican cycads of the genus Dioon. Using 16S rRNA metabarcoding, we describe the composition and diversity of foliar bacterial communities across species and biogeographic regions, highlighting patterns potentially shaped by environmental conditions.

Spatial distribution pattern of the endangered endemic cycad Ceratozamia fuscoviridis (Zamiaceae) in central Mexico

Plant Species Biology, Volume 40, Issue 6, Page 572-583, November 2025.
Spatial distribution pattern were studied for Ceratozamia fuscoviridis, an endangered species in Mexico, based on Ripley's K t and K 12 analysis. Clumped spatial distribution patters was found in individuals of all populations, suggesting low interaction with predators/dispersers and/or evidence of suitable microsites for cycads.
