Reinstatement of the name Anisochilus eriocephalus Benth. (Lamiaceae) supported by micromorphological and molecular data

open access: yesNordic Journal of Botany, Volume 2026, Issue 5, May 2026.
In 2019, A. J. Paton et al. proposed a new taxonomic combination, transferring Anisochilus carnosus (L.f.) Wall. ex Benth. to Coleus strobilifer (Benth.) A.J.Paton, and including Anisochilus eriocephalus Benth. within this broader circumscription.

From living to fossil: ancestral state reconstruction of leaf architecture in extant Lauraceae and its relevance for the fossil record

open access: yesPalaeontology, Volume 69, Issue 3, May/June 2026.
Abstract Lauraceae are a tropical–subtropical angiosperm family that exhibit significant diversity and a rich fossil record, primarily of leaves found worldwide from the Cretaceous to the present. However, the taxonomic placement of many fossil leaves remains uncertain because of morphological convergence and limited variation in leaf characters among ...

DNA Barcoding: Amplification and sequence analysis of rbcl and matK genome regions in three divergent plant species

open access: yesAdvancements in Life Sciences, 2016
Background: DNA barcoding is a novel method of species identification based on nucleotide diversity of conserved sequences. The establishment and refining of plant DNA barcoding systems is more challenging due to high genetic diversity among different ...

A Super‐Pangenome for Cultivated Citrus Reveals Evolutive Features During the Allopatric Phase of Their Reticulate Evolution

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3345-3367, May 2026.
Structure of the cultivated citrus super‐pangenome. ABSTRACT The main genetic diversity observed in cultivated citrus results from a reticulate evolution involving four ancestral taxa whose radiation occurred in allopatry. In such context, GWAS analysis, genome diversity and transcriptomic studies will be significantly enhanced through pangenome ...

Operator scaling with specified marginals

open access: yes, 2018
The completely positive maps, a generalization of the nonnegative matrices, are a well-studied class of maps from $n\times n$ matrices to $m\times m$ matrices.

Isometry and Automorphisms of Constant Dimension Codes [PDF]

open access: yes, 2012
We define linear and semilinear isometry for general subspace codes, used for random network coding. Furthermore, some results on isometry classes and automorphism groups of known constant dimension code constructions are ...

Deformation quantization of the $n$-tuple point

open access: yes, 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.

The first initiative of DNA barcoding of ornamental plants from Egypt and potential applications in horticulture industry.

open access: yesPLoS ONE, 2017
DNA barcoding relies on short and standardized gene regions to identify species. The agricultural and horticultural applications of barcoding such as for marketplace regulation and copyright protection remain poorly explored.

Conservation of selection on matK following an ancient loss of its flanking intron

open access: yesGene, 2009
The chloroplast gene trnK and its associated group II intron appear to be absent in a large and ancient clade that includes nearly 90% of fern species. However, the maturase protein encoded within the intron (matK) is still present and located on the boundary of a large-scale inversion.
