Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

Analysis of phylogenetic relationships of Hordeum (Poaceae) polyploids

, 2015
Hordeum L. (Poaceae, Hordeeae) umfasst 45 Taxa. Die Hälfte dieser Taxa sind tetra- und hexaploid (4x,6x). In dieser Doktorarbeit analysierte ich die phylogenetischen Beziehungen zwischen allen Taxa. Dafür wurden ein plastidärer Locus und 12 nukleäresingle-copy-Loci sequenziert. Dies erfolgte entweder mittels Standard-Klonierung und Sanger-Sequenzierung

Convergent and Divergent Connectivity Patterns of the Arcuate Fasciculus in Macaques and Humans

Advanced Science, EarlyView.
This study employs viral‐based single‐neuron tracing and dMRI‐based whole‐brain tractography to investigate arcuate fasciculus (AF) trajectories in macaque monkeys, and compares with the human AF connectome using spectral embedding. Results demonstrate conserved AF topography spanning temporoparietal‐auditory‐frontal pathways across primates, with ...

Single‐Cell Profiling Across Immune Tissues and Organs Reveals Immunosenescence Signatures in Male Rhesus Monkeys

Advanced Science, EarlyView.
Single‐cell profiling across bone marrow, spleen, mesenteric lymph, and blood in rhesus monkeys reveals organ Immunosenescence. GZMB rises with age, particularly in cytotoxic and terminally exhausted CD8+ T cells, and BHLHE40 emerges as a key transcription factor enriched across multiple CD8+ subsets, regulating pro‐inflammatory and exhaustion‐related ...

Analysis of a data matrix and a graph: Metagenomic data and the phylogenetic tree [PDF]

, 2011
In biological experiments researchers often have information in the form of a graph that supplements observed numerical data. Incorporating the knowledge contained in these graphs into an analysis of the numerical data is an important and nontrivial task.

Comparative and phylogenetic analyses using mitogenomes revealed gene re-arrangement of Boletaceae (Boletales) [PDF]

IMA Fungus
Boletaceae, the largest family in the Boletales order, is an ecologically and economically important group and the phylogenetic studies of this group need to be further developed. The mitogenome is an effective molecular marker for analysing phylogenetic

Molecular phylogenetic analysis of ant subfamily relationship inferred from rDNA sequences

Genes & Genetic Systems, 2003
The relationships among ant subfamilies were studied by phylogenetic analysis of rDNA sequences of 15 species from seven subfamilies. PCR primers were designed on the basis of the rDNA sequence of the Australian bulldog ant, Myrmecia croslandi, previously determined. Phylogenetic trees were constructed using sequences of a fragment of 18S rDNA (1.8 kb),

A Trypsin‐Like Serine Protease ZmNAL1a Fine‐Tunes Maize Floral Transition and Flowering Time

Advanced Science, EarlyView.
This study identifies a trypsin‐like serine protease, ZmNAL1a, that moves from leaves to the shoot apical meristem. ZmNAL1a promotes the floral transition by degrading TOPLESS‐like corepressor REL2, which thereby enhances the expression of key flowering genes through elevating histone acetylation and relieving REL2–ZmEREBP147‐mediated transcriptional ...

Mitochondrial genome of African rice (Oryza glaberrima): comparative analysis and phylogenetic relationships

Mitochondrial DNA. Part B. Resources
We report the first complete mitochondrial genome of African rice (Oryza glaberrima), spanning 376,795 bp across two circular chromosomes (GC: 43.9%) and encoding 65 genes (39 protein-coding, 21 tRNA, 5 rRNA).

GbWAKL20 Phosphorylates GbNFYB8 to Modulate Verticillium Wilt Resistance in Cotton

Advanced Science, EarlyView.
Wall‐associated receptor‐like kinases (WAKLs) play pivotal roles in extracellular–intracellular signal transduction. Upon sensing Verticillium dahliae infestation at the plasma membrane, GbWAKL20 accumulates and transmits signals to the nucleus via endoplasmic reticulum‐mediated Golgi vesicle transport.
