Taxonomic features

This study applies an effective deep learning framework for the classification of microbial sequences. The proposed architecture combines a sequence embedding layer with other layers of a bidirectional Long Short-Term Memory, Seft-attention, and Dropout mechanisms for feature learning. Experimental results demonstrate the strength of the proposed method on datasets of real metagenomes.

The human lung tissue microbiota remains largely uncharacterized, although a number of studies based on airway samples suggest the existence of a viable human lung microbiota. Here we characterized the taxonomic and derived functional profiles of lung microbiota in 165 non-malignant lung tissue samples from cancer patients.

During the ongoing partial taxonomic revision of the genus Echinolaophonte on the basis of populations previously collected from various shores of the Turkish coasts, a new species of Echinolaophonte was discovered and named Echinolaophonte mordoganensis sp. nov. The new species is morphologically most closely related to E. minuta and E. veniliae.

Chaetognaths (arrow worms) are an enigmatic group of transparent planktonic invertebrates and play an important role in the marine food web. Their morphological and developmental features have raised extensive debates since the discovery of the phylum in the 18th century. Uncertainty in the phylogenetic placement of certain chaetognath species still exists and is puzzling many scientists who have tried to clarify this task.

Macro- and micromorphological features of fruit and seeds belonging to 12 taxa genera of Matthiola W.T.Aiton were studied via stereomicroscope and scanning electron microscope. In macromorphological studies, the following variables were investigated: the shape, size, and color of fruit and seeds; the length of fruiting pedicel; the structure of the median vein; stigma (horns); and trichome properties and density in fruit. In micromorphological studies, the presence or absence of seed wings, seed coat pattern in disc and wing, and epidermal cell shape in disc and wing were determined.

In this study, the karyomorphology of 20 Turkish Centaurea (subgenus Cyanus) taxa was examined. The number of chromosomes of 11 taxa belonging to the subgenus Cyanus was determined for the first time. As a result of the karyomorphological studies, the number of basic chromosomes was determined to be x = 8, 10, and 12 in annuals and x = 10 and 11 in perennials. The populations are tetraploid in the seven perennial taxa and polyploidy is not rare for this group. On the other hand, all annual taxa are diploid.

Asperula cankiriense B.Şahin & Sağıroğlu, a new species discovered in the central Anatolian region of Turkey (Çankırı), is described herein. A. cankiriense is similar to Asperula bornmuelleri Velen. However, A. cankiriense differs mainly in its habitus, stem, leaves, and inflorescence features. In this study, the diagnostic morphological features, distribution, habitat and ecology, etymology, conservation status, and taxonomic features of the new species are discussed. Additionally, pollen micromorphological characteristics of A. cankiriense and A.

Taxonomic assignment is a crucial step in a metagenomic project which aims to identify the origin of sequences in an environmental sample. Among the existing methods, since composition-based algorithms are not sufficient for classifying short reads, recent algorithms use only the feature of similarity, or similarity-based combined features.

What is a healthy microbiome? The pursuit of this and many related questions, especially in light of the recently recognized microbial component in a wide range of diseases has sparked a surge in metagenomic studies. They are often not simply attributable to a single pathogen but rather are the result of complex ecological processes.

not be aptly summarized in a single review. Here, we focus on one aspect of diversity (phylogenetic diversity) in one microbial domain (the Bacteria). We restrict our analysis to the highest taxonomic rank (phylum) and attempt to investigate the extent of global phylum level diversity within the Bacteria. Microbial ecology is the study of microbes in the natural environment and their interactions with each other. Investigating the nature of microorganisms residing within a specific habitat is an extremely important component of microbial ecology.

Morphological features of pollen of 11 Turkish taxa belonging to the complex genus Seseli L. were examined using light and scanning electron microscopy. On the basis of exine sculpturing, 3 main types were recognised in Seseli: Type 1, rugulate at equator, psilate-perforate at pole; Type 2, striate-reticulate at equator, rugulate at pole; and Type 3, rugulate at equator, striate at pole.
