Deformation quantization of the $n$-tuple point

, 1998
Contrary to the classical methods of quantum mechanics, the deformation quantization can be carried out on phase spaces which are not even topological manifolds.

Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

Phylogenetic Analysis of Japanese Rosa Species Using matK Sequences.

Breeding Science, 2000
The matK DNA was sequenced in each of the 15 Japanese Rosa taxa, 17 other Asian taxa, and two American taxa to analyse their phylogenetic relationships. All the 14 tested taxa in the section Synstylae, associated with the section Indicae, formed one clade.

Characterization and Identification of Pulsatilla koreana and Pulsatilla tongkangensis Seedlings Based on Morphology, Colorimetric Data, and Molecular Markers

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Pulsatilla tongkangensis, an endemic species growing in the limited areas in Korea, is considered endangered species, and is growing in sympatric with P. koreana enabling natural hybridization. To characterize the true to the type of P. tongkangensis, we integrated morphological traits and molecular analyses of the nuclear ribosomal ITS (nrITS) and the

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 385-400, March 2026.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, Volume 68, Issue 3, Page 694-718, March 2026.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
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 ...

Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1064-1081, March 2026.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

Multiple Checkpoints for the Expression of the Chloroplast-Encoded Splicing Factor MatK    

Plant Physiology, 2013
Abstract The chloroplast genome of land plants contains only a single gene for a splicing factor, Maturase K (MatK). To better understand the regulation of matK gene expression, we quantitatively investigated the expression of matK across tobacco (Nicotiana tabacum) development at the transcriptional, posttranscriptional, and protein ...

Examining macroeconomic models through the lens of asset pricing [PDF]

Dynamic stochastic equilibrium models of the macro economy are designed to match the macro time series including impulse response functions. Since these models aim to be structural, they also have implications for asset pricing.
