Phylogenetic reconciliation provides new insights into the evolutionary diversification of the glutamine synthetase gene family in seed plants. [PDF]

FEBS J
Phylogenetic analyses of glutamine synthetase (GS) in seed plants revealed that all three major evolutionary lineages (GS2, GS1a, and GS1b) must have been present in the common ancestor, with GS2 being the first lineage to diverge. Unlike GS1b, GS1a and GS2 are usually single‐copy genes, even though they underwent duplications that resulted in ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]

Plant Environ Interact
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Discovery of Cyanobacteria Associated with Cycads and Description of Three Novel Species in Desmonostoc (Nostocaceae)

Diversity, 2023
Heterocyte-forming cyanobacteria form symbiotic relationships with several lineages of plants. Here, twenty (20) strains of endosymbiotic cyanobacteria (cyanobionts) with Nostoc-like morphologies were isolated from the highly specialized coralloid roots ...

Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset. [PDF]

Ecol Evol
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.

A Review of Taxonomic Concepts and Species Delimitation in Cycadales

The Botanical review, 2023
Taxonomic data is essential to advance the discovery and description of biodiversity, as well as the study of evolutionary processes. Emerging large-scale datasets and new methods of analysis have provided different approaches to describe biodiversity ...

Behavior and Feeding of Two Beetle Pollinators of Zamia integrifolia (Cycadales): Rhopalotria slossoni (Coleoptera: Belidae) and Pharaxanotha floridana (Coleoptera: Erotylidae)

Florida Entomologist, 2023
Summary Zamia integrifolia L.f. (Cycadales), a threatened cycad native to Florida, depends on 2 native beetle species for pollination: Rhopalotria slossoni (Chevrolat; Coleoptera: Belidae) and Pharaxanotha floridana (Casey; Coleoptera: Erotylidae).

La diversificación de las cícadas y la biodiversidad tropical

Collectanea Botanica, 2012
El reciente e inesperado descubrimiento de que las Cycadales actuales no son relictos Jurásico-Cretácicos (200-65 Mya), ya que todos sus géneros iniciaron su diversificación durante el Mioceno Tardío (12 Mya), ha puesto en entredicho un mito evolutivo ...
