Phylogenetic systematics of Juncaceae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...

Origin of subgenomes in the circumboreal, allopolyploid, carnivorous plant Drosera anglica

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The parentage of the widespread allopolyploid Drosera anglica, a member of the carnivorous sundew genus, remains uncertain despite over 100 years of morphological, cytological, and, more recently, molecular study. Methods Using transcriptomic and genomic data from 12 species of Drosera sect. Drosera, including four D.

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...
