Identification and quantification of microplastic particles in drinking water treatment sludge as an integrative approach to determine microplastic abundance in a freshwater river.

Environ Pollut 2021 Jun 4;286:117524. Epub 2021 Jun 4.

Leibniz-Institut für Ostseeforschung Warnemünde (IOW), D-18119, Rostock, Germany. Electronic address:

Microplastic (MP) has been detected ubiquitously in freshwater systems. Until now MP sampling, however, is predominantly based on short-term net or pumping and filtration systems which can only provide snapshots of MP abundance; especially in flowing water bodies. To improve representativeness in the determination of MP occurrences in these aquatic compartments, an integrative approach that covers larger water volumes for a longer period of time is required.

Center for Genomics and Systems Biology, Department of Biology, New York University, 12 Waverly Pl, New York, NY 10003, United States. Electronic address:

Single-cell genomics, particularly single-cell transcriptome profiling by RNA sequencing have transformed the possibilities to relate genes to functions, structures, and eventually phenotypes. We can now observe changes in each cell's transcriptome and among its neighborhoods, interrogate the sequence of transcriptional events, and assess their influence on subsequent events. This paradigm shift in biology enables us to infer causal relationships in these events with high accuracy. Read More

Recent strategies for inhibiting multidrug-resistant and β-lactamase producing bacteria: A review.

Colloids Surf B Biointerfaces 2021 Jun 6;205:111901. Epub 2021 Jun 6.

Enzyme and Microbial Biochemistry Laboratory, Department of Chemistry, Indian Institute of Technology Delhi, India. Electronic address:

β-lactam antibiotics are one of the most commonly used drugs for treating bacterial infections, but their clinical effectiveness has been severely affected with bacteria developing resistance against their action. Production of β-lactamase enzymes by bacteria that can degrade β-lactams is the most common mechanism of acquiring such resistance, leading to the emergence of multiple-drug resistance in them. Therefore, the development of efficient approaches to combat infections caused by β-lactamase producing and multidrug-resistant bacteria is the need of the hour. Read More

Synergistic effects of plant growth promoting rhizobacteria and silicon dioxide nano-particles for amelioration of drought stress in wheat.

Plant Physiol Biochem 2021 Jun 4;166:160-176. Epub 2021 Jun 4.

Department of Botany, S.P. College, Srinagar, Jammu, and Kashmir, India.

Drought tolerant plant growth-promoting rhizobacteria (PGPR) can confer drought tolerance in plants, when inoculated, and this effect can be more pronounced by their combined application with silicon oxide nanoparticles (SiO NPs). In this research, drought-tolerant and plant growth-promoting rhizobacterial strains were isolated from the rhizospheric soil of wheat plants growing in the arid region of Pakistan. Out of 30 isolated strains, three rhizobacterial strains were selected based on their drought tolerance, higher phytohormones (indole acetic acid (IAA), abscisic acid (ABA), and cytokinin (CK), and osmolyte (proline and sugar) production ability.

The Sw-5b NLR nucleotide-binding domain plays a role in oligomerization and its self-association is important for the activation of cell death signaling.

J Exp Bot 2021 Jun 11. Epub 2021 Jun 11.

Key Laboratory of Plant Immunity, Department of Plant Pathology, Nanjing Agricultural University, Nanjing 210095, China.

Plant and animal intracellular nucleotide-binding and leucine-rich repeat (NLR) receptors play important roles in sensing pathogens and activating defense signaling. However, the molecular mechanisms underlying the activation of host defense signaling by NLR proteins remain largely unknown. Many previous studies have determined that the coil-coil (CC) or Toll and interleukin-1 receptor/resistance protein (TIR) domain of NLR proteins and their dimerization/oligomerization are critical for activating downstream defense signaling.

State Key Laboratory for Crop Genetics and Germplasm Enhancement, JCIC-MCP, CIC-MCP, Nanjing Agricultural University, No.1 Weigang, Nanjing, Jiangsu 210095, P.R. China.

Although lagging behind studies in humans and other mammals, R-loop studies in plants have recently entered an exciting stage in which the roles of R-loops in gene expression, genome stability, epigenomic signatures, and plant development and stress responses are being elucidated. Here, we reviewed the strengths and weaknesses of existing methodologies, which were largely developed for R-loop studies in mammals, and then we discussed the potential challenges of applying these methodologies to R-loop studies in plants. We then focused on recent advances in the functional characterization of R-loops in Arabidopsis thaliana and rice. Read More
