Recent sequencing studies on healthy skin and esophagus have found that, as we age, these tissues become colonized by mutant clones of cells carrying driver mutations in traditional cancer genes. This comment summarizes these findings and discusses their possible implications for our understanding of cancer, ageing, and other diseases.

Drawing genotype-to-phenotype maps in tumors is of paramount importance for understanding tumor heterogeneity. Assignment of single cells to their tumor clones of origin can be approached by matching the genotypes of the clones to the mutations found in RNA sequencing of the cells.

Escherichia coli is the leading cause of bloodstream infections, associated with a significant mortality. Recent genomic analyses revealed that few clonal lineages are involved in bloodstream infections and captured the emergence of some of them. However, data on within sequence type (ST) population genetic structure evolution are rare.

Extension of prostate cancer beyond the primary site by local invasion or nodal metastasis is associated with poor prognosis. Despite significant research on tumour evolution in prostate cancer metastasis, the emergence and evolution of cancer clones at this early stage of expansion and spread are poorly understood.

Streptococcus pneumoniae is a gram-positive opportunistic pathogen, and infection risks of S. pneumoniae can be profoundly augmented by its acquired multidrug-resistance (MDR). The rapid development of MDR in S. pneumoniae was attributed to the international dissemination of a small number of multidrug-resistant “clones.”

Animal cloning is the process of producing an entire organism that theoretically has the same genome as its donor cell line. To validate the success of SCNT, one must verify that the genetic source of the cloned organism is identical to the donor cell. However, none of the studies have performed to identify the genetic characteristics in the stage of preimplantation development of cloned embryo.

This study was conducted to estimate genetic relationships among banana clones growing in Turkey via some morphological parameters and two molecular marker systems. In terms of yield parameters such as bunch weight, hand number, fruit weight, and total fruit number, Grand Nain (GN) clone came to the forefront with the highest values. It was followed by Azman (AZ), Dwarf Cavendish (DC), and Erdemli Yerli (EY) clones, respectively.

Chitinolytic bacteria and their chitinases have attracted great attention due to potential applications in various fields, including medicine, food processing, agriculture. To develop a novel type of biocontrol agents alternative chemical agents for phytopathogenic controlling, we focus on bacteria possessed high chitinase activity. In this study, a chitinase gene (chiB) from Bacillus velezensis RB.IBE29 was identified, cloned, and analyzed.

Abdominal surgery carries significant morbidity and mortality, which is in turn associated with an enormous use of healthcare resources. We describe the clinical course of 30 Intensive Care Unit (ICU) patients who underwent abdominal surgery and showed severe infections caused by Klebsiella pneumoniae sequence type (ST) 258 producing K. pneumoniae carbapenemase (KPC-Kp).

Measuring gene expression of tumor clones at single-cell resolution links functional consequences to somatic alterations. Without scalable methods to simultaneously assay DNA and RNA from the same single cell, parallel single-cell DNA and RNA measurements from independent cell populations must be mapped for genome-transcriptome association.

While SNV detection from abundant single-cell RNA sequencing (scRNA-seq) data is applicable and cost-effective in identifying expressed variants, inferring sub-clones, and deciphering genotype-phenotype linkages, there is a lack of computational methods specifically developed for SNV calling in scRNA-seq.

Somatic evolution of malignant cells produces tumors composed of multiple clonal populations, distinguished in part by rearrangements and copy number changes affecting chromosomal segments. Whole genome sequencing mixes the signals of sampled populations, diluting the signals of clone-specific aberrations, and complicating estimation of clone-specific genotypes.

Identification of causal mutations in barley and wheat is hampered by their large genomes and suppressed recombination. To overcome these obstacles, we have developed MutChromSeq, a complexity reduction approach based on flow sorting and sequencing of mutant chromosomes, to identify induced mutations by comparison to parental chromosomes.

The purpose of the study was to measure the secretion levels of recombinant glucoamylase from Pichia pastoris, by using the α-mating factor secretion signal peptide (α-MF) and the native signal peptide of glucoamylase from Aspergillus flavus NSH9. The Aspergillus flavus NSH9 gene (with and without native signal sequences), encoding a pH and thermostable glucoamylase with an SBD, was successfully cloned and expressed in Pichia pastoris to produce recombinant glucoamylases.

Flowers of safflower (Carthamus tinctorius L.) have been widely used in traditional Chinese medicine because of their ability to improve cerebral blood flow. The major active ingredients in safflower are flavonoids. To date, few flavonoid biosynthesis genes have been cloned from this species. In our previous research, four isoform chalcone isomerase genes were screened. In this study, a new chalcone isomerase gene (designated as CtCHI-N) was cloned from a safflower cDNA library. A 696-bp cDNA for CtCHI-N was cloned, and its sequence was subsequently analyzed.

The cDNA encoding lipase enzyme was cloned from Olea europaea var. europaea cv. Gemlik leaves using the RACE method. The full nucleotide sequence was 1546 bp long and encoded a putative protein of 412 amino acid long protein. The amino acid sequence showed identity to Triacylglycerol Lipase 1 sequences from different plants. A phylogenetic tree was constructed showing relations with various plant lipases.
