New Approach to Revolutionize Synthetic Biology

For the first time, scientists at the Lawrence Berkeley National Laboratory of the Department of Energy (Berkeley Lab) have created a genome-scale method to map the regulatory role of transcription factors, proteins that are essential for controlling gene expression, and a plant’s physiological features.

‘Lost World’ Discovery Could Change the Understanding of Our Earliest Ancestors

The discovery of a "lost world" of ancient organisms that lived in Earth's waterways at least 1.6 billion years ago could change our understanding of our earliest ancestors.

Study Advances Understanding of the Deep Evolutionary History of Viruses

Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.

Membrane-Remodeling Proteins in Cyanobacteria are Similar to Protein Found in Higher Organisms

The cells of living organisms are equipped with proteins that are involved in the shaping and remodeling of cellular membranes, thereby performing important tasks.

Metabolic Network Compatibility Not Likely the Limiting Factor in Prokaryotic Endosymbiosis

"One of the great mysteries of biology," says Eric Libby, former SFI Postdoctoral Fellow, now an associate professor at the Integrated Science Lab (IceLab), Umeå University in Sweden, "is eukaryogenesis, or how eukaryotes arose." Scientists consider this to be a period of major evolutionary transition, critical to our understanding of the history and evolution of life on Earth.

A Previously Unknown Mechanism for DNA Folding Revealed

A hitherto unknown mechanism for DNA folding is described in a study in Nature published by researchers from Karolinska Institutet and the Max Planck Institute for Biophysics.

Scientists develop a detailed "protein atlas" of a pathogen for the first time

A parasite which has devasting impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells – providing clues to their function and helping to identify potential drug targets.

A reliable way to downregulate gene translation in plants

By carefully constructing upstream open reading frames (uORFs), Caixia Gao’s team at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) has created a new technique for downregulating gene translation to a predictable and desirable level in plants.

New insights into the distribution and regulation of meiotic DSB hotspots

A new method, DNA End tailing and sequencing (DEtail-seq), for meiotic DNA double-strand break (DSB) profiling was developed recently.

Identifying the molecular switch that regulates autophagy in plants

Autophagy, commonly known as “self-eating,” is a cellular quality control mechanism that relieves the cell of protein aggregates and damaged organelles. This system is inert under ordinary conditions and is only activated in the presence of persistent cellular stress.

A soybean genome in pan-3D

For cis-regulatory elements in the genome to function, which is crucial for gene regulation, a high-order chromatin structure is required. Three-dimensional (3D) genome organization in eukaryotes exhibits a hierarchical structure.

Molecular mechanism behind microtubule dynamics in R. contractilis

Raphidocystis contractilis belongs to Heliozoa, a group of eukaryotes that is generally seen in brackish, fresh, and seawater.

Effective anticancer strategy for selective killing of cancer cells

A study team headed by Dr Yuanliang Zhai from The University of Hong Kong’s (HKU) School of Biological Sciences and his associates from The Hong Kong University of Science and Technology (HKUST) and Institut Curie in France discovered a new mechanism of the human MCM2-7 complex in controlling replication initiation, which can be employed as a unique and effective anticancer method with the potential for selective death of cancer cells.

Novel insights into the elongation dynamics of eukaryotic cells

The proper functioning of numerous proteins generated in cells by ribosomes is essential for life. This diversified variety of proteins, called proteome, is sustained by the ribosomes’ vigorous translation elongation of amino acid sequences.

New effort to generate high quality reference genomes for 1,000 known species of euglenoids

The Euglena International Network (EIN) (https://euglenanetwork.org/), founded in 2020, is a global consortium of hundreds of scientists around the world with the collective goal of supporting euglenoid science through collaborative and integrative omics between academics and industry.
