Cellular network transforms fungus when temperatures rise

(Phys.org) —When the infectious fungus Histoplasma capsulatum feels the temperature start to rise, it undergoes a transformation. As it shifts its shape from long filaments to oval cells, the pathogen switches on genes ...

Counting small RNA in disease-causing organisms

Small molecules of RNA (tens to hundreds of nucleotides in length) play a key regulatory role in bacteria. Due to their small size, directly measuring the number of small RNA (sRNA) present in a single bacterium has proven ...

Gene silencing set to boost agricultural yields

Researchers from Murdoch University have developed an environmentally friendly 'gene silencing' method to control Root Lesion Nematodes, plant pathogens known to reduce crop yields in major crops such as wheat and barley ...

New study shows how Salmonella colonises the gut

(Phys.org) —Salmonella is a major cause of human diarrhoeal infections and is frequently acquired from chickens, pigs and cattle, or their products. Around 94 million such infections occur in people worldwide each year, ...

Gene invaders are stymied by a cell's genome defense

Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that ...

Rare form of active 'jumping genes' found in mammals

Much of the DNA that makes up our genomes can be traced back to strange rogue sequences known as transposable elements, or jumping genes, which are largely idle in mammals. But Johns Hopkins researchers report they have identified ...

Study turns parasite invasion theory on its head

Current thinking on how the Toxoplasma gondii parasite invades its host is incorrect, according to a study published today in Nature Methods describing a new technique to knock out genes. The findings could have implications ...
