Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

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

open access: yesJournal of Systematics and Evolution, EarlyView.
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.

Deciphering the biosynthetic pathways of lichen acids

open access: yesNew Phytologist, EarlyView.
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Phylogenomic Models from Tree Symmetries

open access: yesSIAM Journal on Applied Algebra and Geometry
A model of genomic sequence evolution on a species tree should include not only a sequence substitution process, but also a coalescent process, since different sites may evolve on different gene trees due to incomplete lineage sorting. Chifman and Kubatko initiated the study of such models, leading to the development of the SVDquartets methods of ...

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

open access: yesNew Phytologist, EarlyView.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Functional Classification Using Phylogenomic Inference

open access: yesPLoS Computational Biology, 2006
Phylogenomic inference of protein (or gene) function attempts to address the question, “What function does this protein perform?” in an evolutionary context. As originally outlined by Jonathan Eisen [1–3], phylogenomic inference of protein function is a multistep process involving selection of homologs, multiple sequence alignment (MSA), and ...

WRKY27‐RAP2.7 Regulatory Module Promotes Cold Tolerance via Modulation of Lignin Biosynthesis and Redox Homeostasis by Regulating Cinnamyl Alcohol Dehydrogenase 7 and Glutathione S‐Transferase F6

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Cold stress adversely affects plant growth and development, significantly limiting fruit yield and quality in citrus. Ichang papeda (Citrus ichangensis), a cold‐tolerant citrus species, serves as a valuable genetic resource for studying cold adaptation, yet the key genes and their modes of action underlying the cold stress response remain ...

A Super‐Pangenome for Cultivated Citrus Reveals Evolutive Features During the Allopatric Phase of Their Reticulate Evolution

open access: yesPlant Biotechnology Journal, EarlyView.
Structure of the cultivated citrus super‐pangenome. ABSTRACT The main genetic diversity observed in cultivated citrus results from a reticulate evolution involving four ancestral taxa whose radiation occurred in allopatry. In such context, GWAS analysis, genome diversity and transcriptomic studies will be significantly enhanced through pangenome ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

open access: yesPlant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Chromosome‐Level Genome Assembly of the Allotetraploid Gynostemma pentaphyllum Provides Novel Insights Into the Biosynthesis of Ginsenoside and Gypenoside LVI

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Gynostemma pentaphyllum, a herb used in tea and traditional Chinese medicine, shows geographic variation in its production of valuable dammarane‐type ginsenosides and gypenoside LVI between populations from Suining (SN) and Nanning (NN). To elucidate the mechanisms underlying this differential metabolite accumulation, a chromosome‐level genome
