Testing mitochondrial sequences and anonymous nuclear markers for phylogeny reconstruction in a rapidly radiating group: molecular systematics of the Delphininae (Cetacea: Odontoceti: Delphinidae)

BMC Evolutionary Biology, 2009
Background Many molecular phylogenetic analyses rely on DNA sequence data obtained from single or multiple loci, particularly mitochondrial DNA loci. However, phylogenies for taxa that have undergone recent, rapid radiation events often remain unresolved.

Perinatal outcomes in normotensive versus hypertensive HELLP syndrome

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To compare maternal and neonatal outcomes between women with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome with and without associated hypertension. Methods This was a retrospective cohort study at a tertiary university‐affiliated medical center including all singleton HELLP cases >24 weeks gestation (January ...

Fusion of protoplasts with irradiated microprotoplasts as a tool for radiation hybrid panel in citrus Fusão de protoplastos com microprotoplastos irradiados como ferramenta para painel híbrido de radiação em citros

Pesquisa Agropecuária Brasileira, 2009
The objective of this work was to combine asymmetric somatic hybridization (donor-recipient fusion or gamma fusion) to microprotoplast-mediated chromosome transfer, as a tool to be used for chromosome mapping in Citrus.

A dominant gene for male sterility in Salvia miltiorrhiza Bunge. [PDF]

PLoS ONE, 2012
A natural male sterile mutant of Salvia miltiorrhiza (Labiatae, Sh-B) was found during field survey in 2002. Our objective was to analyze its genetic mechanism for producing F1 hybrid seeds and to develop a molecular marker linked to male sterile gene ...

From wild to tamed: Reimagining novel crops through omics and local plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Hybridization patterns and research effort in Asteraceae, a megadiverse and economically important plant family

PLANTS, PEOPLE, PLANET, EarlyView.
Plant hybridization is increasingly recognized as an important evolutionary process, and a deeper understanding of hybridization is necessary for its application to agriculture, conservation, and ecological solutions. Here, we assess correlates of hybridization in the megadiverse and societally important family Asteraceae and how and where hybrids have

Needle in a haystack: Holocene history of European larch in Central Europe revisited

PLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

Optimizing equity and efficiency in the aerial firefighting resource allocation problem

International Transactions in Operational Research, EarlyView.
Abstract This study addresses the aerial firefighting resource allocation problem, formulated as the strategic prepositioning of a heterogeneous aerial firefighting fleet across capacity‐constrained airbases. A novel bi‐objective model is proposed that simultaneously optimizes efficiency (aggregate risk‐weighted accessibility) and equity (minimized ...
