Synoptic revision of Kolobopetalum and Rhigiocarya (Menispermaceae) with the description of a new Kolobopetalum species from Gabon, and a new specific combination in Rhigiocarya from West Africa [PDF]

open access: yesPlant Ecology and Evolution, 2021
Background and aims – In the framework of the Menispermaceae treatment for the Flore du Gabon, the closely related genera Kolobopetalum and Rhigiocarya are synoptically revised.Material and methods – Standard practices of herbarium taxonomy have been ...

Assembling genomes of non-model plants: A case study with evolutionary insights from Ranunculus (Ranunculaceae). [PDF]

open access: yesPlant J
SUMMARY Whereas genome sequencing and assembly technologies are improving, cost can still be prohibitive for plant species with large, complex genomes. As a consequence, genomics work on some taxa in evolutionarily pivotal positions in the vascular plant tree of life has been hampered.

Post-Dispersal Embryo Growth Is a Thermal Checkpoint for Seed Regeneration. [PDF]

open access: yesEcol Evol
Seeds with underdeveloped embryos must complete a phase of post‐dispersal embryo growth before radicle emergence, yet this developmental stage is typically treated as a passive delay within dormancy frameworks rather than as an independent ecological process.

Over 100 Million Years of Enzyme Evolution Underpinning the Production of Morphine in the Papaveraceae Family of Flowering Plants

open access: yesPlant Communications, 2020
Phylogenomic analysis of whole genome sequences of five benzylisoquinoline alkaloid (BIA)-producing species from the Ranunculales and Proteales orders of flowering plants revealed the sequence and timing of evolutionary events leading to the ...

A high-quality Buxus austro-yunnanensis (Buxales) genome provides new insights into karyotype evolution in early eudicots

open access: yesBMC Biology, 2022
Background Eudicots are the most diverse group of flowering plants that compromise five well-defined lineages: core eudicots, Ranunculales, Proteales, Trochodendrales, and Buxales.

Paleopolyploidies and Genomic Fractionation in Major Eudicot Clades

open access: yesFrontiers in Plant Science, 2022
Eudicots account for ~75% of living angiosperms, containing important food and energy crops. Recently, high-quality genome sequences of several eudicots including Aquilegia coerulea and Nelumbo nucifera have become available, providing an opportunity to ...

Comparative floral development in Lardizabalaceae (Ranunculales) [PDF]

open access: yesBotanical Journal of the Linnean Society, 2011
Abstract Ovules development and structure of 6 species of 5 genera in Lardizabalaceae were studied under SEM and LM. Ovule morphology show diversity in the family: anatropous ( Sinofranchetia and Decaisnea ) or campylotropous ( Sargentodoxa , Akebia and Holboellia ); ovule number is 1 ( Sargentodoxa ) to 20 (even up to 180 in Akebia and ...

Elucidation of the (R)-enantiospecific benzylisoquinoline alkaloid biosynthetic pathways in sacred lotus (Nelumbo nucifera)

open access: yesScientific Reports, 2023
Benzylisoquinoline alkaloids (BIAs) are a structurally diverse group of plant specialized metabolites found mainly in members of the order Ranunculales, including opium poppy (Papaver somniferum), for which BIA biosynthetic pathways leading to the ...

Early eudicot reproductive structure: Fruit and flower morphology of Ranunculaecarpus Samyl. from the Early Cretaceous of eastern Siberia

open access: yesActa Palaeobotanica, 2018
Floral and fruit morphology of the early eudicot Ranunculaecarpus quinquecarpellatus Samyl. is described based on details from sectioning and microscopy of the permineralized type material from the Albian Buor-Kemyus Formation of the Zyryanka coal basin.
