recommendations! Published in 2025 at "Ecology and Evolution"

DOI: 10.1002/ece3.70950

Abstract: ABSTRACT Within the ciliate class Oligohymenophorea, many evolutionary relationships among taxa remain unresolved. This study incorporates 97 new sequences from 30 oligohymenophorean populations, including nuclear small subunit ribosomal (SSU‐rRNA) genes, nuclear ITS1‐5.8S‐ITS2 rRNA regions, nuclear… read more here.

DOI: 10.1007/978-1-0716-1499-0_7

Abstract: Preparative synthesis of RNA is a challenging task that is usually accomplished by either chemical or enzymatic polymerization of ribonucleotides in vitro. Herein, we describe an alternative approach in which RNAs of interest are expressed… read more here.

DOI: 10.1007/s00709-019-01364-4

Abstract: Histone modification plays a significant role in plant responses to abiotic stress. However, there are little scientific studies available on the involvement of dynamic changes in histone modification in the heat stress response in maize.… read more here.

DOI: 10.1007/s11033-018-4274-9

Abstract: Sequences in the stem-loop part of 16S ribosomal RNA (rRNA) are considered to be crucial for predicting antibiotic resistance. Mutant sequences have been reported to be helpful in the prediction of spectinomycin resistance. It is… read more here.

DOI: 10.1007/s12035-018-0989-9

Abstract: Ribosome biogenesis, including the RNA polymerase 1 (Pol1)-mediated transcription of rRNA, is regulated by the pro-epileptogenic mTOR pathway. Therefore, hippocampal Pol1 activity was examined in mouse models of epilepsy including kainic acid- and pilocarpine-induced status… read more here.

DOI: 10.1016/j.chembiol.2018.09.010

Abstract: Apart from their antimicrobial properties, tetracyclines demonstrate clinically validated effects in the amelioration of pathological inflammation and human cancer. Delineation of the target(s) and mechanism(s) responsible for these effects, however, has remained elusive. Here, employing… read more here.

DOI: 10.1016/j.ijfoodmicro.2018.01.020

Abstract: During wine production, some yeasts enter a Viable But Not Culturable (VBNC) state, which may influence the quality and stability of the final wine through remnant metabolic activity or by resuscitation. Culture-independent techniques are used… read more here.

DOI: 10.1021/acscentsci.3c01413

Abstract: The biosynthetic capability of the bacterial ribosome motivates efforts to understand and harness sequence-optimized versions for synthetic biology. However, functional differences between natively occurring ribosomal RNA (rRNA) operon sequences remain poorly characterized. Here, we use… read more here.
