Study identifies sex-adapted color-change gene in locusts

The locust on the right is expressing the protein that produces a bright yellow coloration in adult males. Credit: Sam Craft A study by a Texas A&M AgriLife Research provides key insights into the scientist changes that occur in locusts that lead to swarms of biblical proportion. The AgriLife Research study is highlighted in the … Read more

Team discovers new plant gene reprogramming mechanism

Credit: CC0 Public Domain Researchers Albert Cairó and Karel Riha of the Central European Institute of Technology (CEITEC) and their colleagues have discovered a previously unknown mechanism that is responsible for reprogramming gene expression in plants during the transition period when one cell differentiates into another one. The mechanism occurs at the end of meiosis, … Read more

Researchers track protein binding, build synthetic proteins to study gene expression

Credit: Unsplash/CC0 Public Domain How does a nose remember that it’s a nose? Or an eye remember that it’s an eye? As scientists probe the question of how cells remember what kind of cells they are supposed to be, or their genetic lineage, it’s important to understand how cells express different genes without changing the … Read more

Borrowed gene helps maize adapt to high elevations, cold temperatures

Credit: Pixabay/CC0 Public Domain Researchers at North Carolina State University show that an important gene in maize called HPC1 modulates certain chemical processes that contribute to flowering time, and has its origins in “teosinte mexicana,” a precursor to modern-day corn that grows wild in the highlands of Mexico . The findings provide insight into plant … Read more

Changes in oceanographic fronts affect the gene flow among marine crab populations

Scientific Reports (2022). DOI: 10.1038/s41598-022-13941-4″ width=”800″ height=”520″/> The team focused the study on the harbor crab (Liocarcinus depurator), a decapod crustacean of commercial interest.

DOI: 10.1038/s41598-022-13941-4 In the Mediterranean and the Atlantic, the intensity and location of the oceanographic fronts that limit the gene connectivity among populations of marine crabs over … Read more

A gene in tuberculosis bacteria is found essential for siderophore secretion and virulence

600 of all cultures was 0.01. Growth curves of M. tuberculosis mc26230 (wt), Δrv0455c (M. tuberculosis ML2203), Δrv0455c::rv0455c (M. tuberculosis ML2205), ΔmmpS4/S5 (M. tuberculosis MLmbtD859) and Δ (M. tuberculosis ML1600) in (a) self-made low-iron ( The M. tuberculosis Δrv0455c mutant is hypersensitive to exogenous siderophores. a–d The indicated M. tuberculosis strains were grown in low-iron … Read more

How a gene mutation leads to higher intelligence

Drosophila sp fly. Credit: Muhammad Mahdi Karim / Wikipedia. GNU Free Documentation License, Version 1.2 When genes mutate, this can lead to severe diseases of the human nervous system. Researchers at Leipzig University and the University of Würzburg have now used fruit flies to demonstrate how, apart from the negative effect, the mutation of a … Read more

Scientists engineer new tools to electronically control gene expression

Illustration of how the system works. Credit: Imperial College London Researchers, led by experts at Imperial College London, have developed a new method that allows gene expression to be precisely altered by supplying and removing electrons. This could help control biomedical implants in the body or reactions in large ‘bioreactors’ that produce drugs and other … Read more
