The genome is tightly organised (packaged) within the cell nuclei. This three-dimensional (3D) genome organisation is fundamental, given that it regulates gene expression.
A study led by scientists at the Universitat Autònoma de Barcelona (UAB) now demonstrates using mice models that the 3D organisation of the genome is extremely dynamic during the formation of male germ cells (precursors of spermatozoa) and that alterations in this structure can affect fertility.
The research, published in
Nature Communications, describes the 3D genome organisation in germ cells of wild populations of house mice (Mus musculus domesticus) with chromosomal rearrangements, alterations in the genome which change the structure of chromosomes. The study represents a significant advance in research into mechanisms generating and regulating the structure and function of the genome during the formation of gametes (oocytes and sperm).

New Brunswick, N.J. (May 12, 2021) - A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.
The study appears in the journal
Microorganisms.
Bacteria stimulate root hair growth in all plants that form root hairs, so the researchers examined the chemical interactions between bacteria inside root cells and the root cell.
They found that bacteria are carried in seeds and absorbed from soils, then taken into root cells where the bacteria produce ethylene, a plant growth hormone that makes root cells grow root hairs. When the root hair grows, it ejects some of the bacteria back into the soil, then the remaining bacteria in the root hairs replicate and trigger a growth spurt every 15 minu
