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

Journal 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.

The induction of stromule formation by a plant DNA-virus in epidermal leaf tissues suggests a novel intra- and intercellular macromolecular trafficking route

Frontiers in Plant Science, 2012
Stromules are dynamic thin protrusions of membrane envelope from plant cell plastids. Despite considerable progress in understanding the importance of certain cytoskeleton elements and motor proteins for stromule maintenance, their function within the ...

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

Journal 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.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Starch synthesis in Brachypodium distachyon endosperm occurs in dynamic, connected amyloplast compartments

New Phytologist, EarlyView.
Summary The morphology of starch granules is a major determinant of the functional and nutritional properties of starch and is highly variable among cereal species. Much of this morphological variation stems from differences in the spatial and temporal patterns of starch granule initiation in amyloplasts during grain development.

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, EarlyView.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.
