"The PO-Driven Model": A Basic Science Pipeline for the Bioeconomy with Solutions Inspired by Convergent Evolution for Connecting Parallel Research Ideas.

Basic science research, also called "curiosity-driven research," is fundamental work done with no immediate economic goals but rather a focus on discovery for discovery's sake. However, basic science research is often needed to seed more applied, economically-oriented, research. Both basic and applied research efforts are important aspects of the "bioeconomy" defined here as the contributions to the overall economy from various biology-related fields spanning everything from museum-based natural history research to agricultural food and material production to healthcare.

Evolutionary relationships within the lamioid tribe Synandreae (Lamiaceae) based on multiple low-copy nuclear loci.

The subfamily Lamioideae (Lamiaceae) comprises ten tribes, of which only Stachydeae and Synandreae include New World members. Previous studies have investigated the phylogenetic relationships among the members of Synandreae based on plastid and nuclear ribosomal DNA loci. In an effort to re-examine the phylogenetic relationships within Synandreae, the current study incorporates data from four low-copy nuclear loci, PHOT1, PHOT2, COR, and PPR.

Genetic diversity of historical Atlantic walruses (Odobenus rosmarus rosmarus) from Bjørnøya and Håøya (Tusenøyane), Svalbard, Norway.

Background: The population size of Atlantic walruses (Odobenus rosmarus rosmarus) is depleted relative to historical abundance levels. In Svalbard, centuries of over-exploitation brought the walrus herds to the verge of extinction, and such bottlenecks may have caused loss of genetic variation. To address this for Svalbard walruses, mitochondrial haplotypes of historical walruses from two major haul-out sites, Bjørnøya and Håøya, within the Archipelago were explored using bone samples from animals killed during the peak period of harvesting.

New insights into evolutionary relationships within the subfamily Lamioideae (Lamiaceae) based on pentatricopeptide repeat (PPR) nuclear DNA sequences.

Premise Of The Study: Lamioideae, one of the most species-rich subfamilies within Lamiaceae, exhibits a remarkable diversity in morphology and habit and is found in many temperate to subtropical regions across the globe. Previous studies based on chloroplast DNA (cpDNA) sequence data produced a tribal classification of Lamioideae, but so far this has not been confirmed with nuclear DNA loci.

Methods: We investigated sequence variation in a low-copy nuclear pentatricopeptide repeat (PPR) region and compared the phylogenetic results with previously published sequence data from a concatenated data set comprising four cpDNA loci.

Untangling reticulate evolutionary relationships among New World and Hawaiian mints (Stachydeae, Lamiaceae).

The phenomenon of polyploidy and hybridization usually results in novel genetic combinations, leading to complex, reticulate evolution and incongruence among gene trees, which in turn may show different phylogenetic histories than the inherent species tree. The largest tribe within the subfamily Lamioideae (Lamiaceae), Stachydeae, which includes the globally distributed Stachys, and one of the largest Hawaiian angiosperm radiations, the endemic mints, is a widespread and taxonomically challenging lineage displaying a wide spectrum of morphological and chromosomal diversity. Previous molecular phylogenetic studies have showed that while the Hawaiian mints group with Mexican-South American Stachys based on chloroplast DNA sequence data, nuclear ribosomal DNA (nrDNA) sequences suggest that they are most closely related to temperate North American Stachys.

Phylogeny and biogeography of New World Stachydeae (Lamiaceae) with emphasis on the origin and diversification of Hawaiian and South American taxa.

Due to its unique geological history and isolated location, the Hawaiian Archipelago provides an ideal setting for studies on biogeography, phylogeny and population biology. Species richness in these islands has been attributed to unique colonization events. The Hawaiian mints comprising of three endemic genera represent one of the largest radiations in the island.

Asymmetrical gene flow in a hybrid zone of Hawaiian Schiedea (Caryophyllaceae) species with contrasting mating systems.

Asymmetrical gene flow, which has frequently been documented in naturally occurring hybrid zones, can result from various genetic and demographic factors. Understanding these factors is important for determining the ecological conditions that permitted hybridization and the evolutionary potential inherent in hybrids. Here, we characterized morphological, nuclear, and chloroplast variation in a putative hybrid zone between Schiedea menziesii and S.
