Bridging a biogeographic 'gap' : microfossil evidence for the quillwort Isoetes on the Cumberland Plain west of Sydney during the early Colonial period [PDF]

open access: yes, 2013
Fossil spores preserved on historical archaeological sites at Parramatta and Richmond indicate that two or more species of the quillwort genus Isoetes (family Isoetaceae) were growing along rivers on the Cumberland Plain, west of Sydney, during the late ...

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.

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

open access: yesMedical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Climate adaptation and functional constraints drive pollen evolution in Apiales

open access: yesNew Phytologist, EarlyView.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Stronger expression of crassulacean acid metabolism (CAM) requires effective cuticular transpiration barriers but not necessarily strong succulence

open access: yesNew Phytologist, EarlyView.
Summary Discovering functional and evolutionary interdependencies of hydraulic traits and crassulacean acid metabolism (CAM) is crucial to understand CAM phenotype diversity and convergence. In complex traits such as CAM, the co‐option of associated traits strongly impacts the evolutionary outcome.

Alternaria alternata Effector Aa593 Promotes Virulence by Hijacking the CmNAC29‐Mediated Abscisic Acid Biosynthesis Pathway in Chrysanthemum

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The interaction between plants and pathogens has long been an actively researched field of plant immunity. In this study, we found an Aa593/CmNAC29‐CmNCED3 module associated with the interaction between chrysanthemum and the fungal pathogen Alternaria alternata.

Engineering of the Flavone Rutinoside Biosynthetic Pathway Enables Production of Diosmin, a Venoactive Compound in Solanum lycopersicum and Nicotiana tabacum

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Diosmin is often used as a dietary supplement, and it is sometimes used to make phlebotropic drugs for venous diseases. Traditionally, diosmin is obtained by the dehydrogenation of the flavanone glycoside hesperidin through chemical semisynthesis.
