Researchers reveal how myrtle rust pathogen breaks into a host plant

A recent study looking at the molecular foundation of myrtle rust reveals how the pathogen breaks into a host plant and how the host plant responds. This insight will inform the design of useful tools to prevent future break-ins ...

Study finds ways to enhance transcription factor activity

Transcription factors regulate gene expression by binding specific sequences on DNA, which is an essential step to producing messenger RNAs from protein-coding genes. Denes Hnisz's lab, in collaboration with Martin Vingron's ...

New molecules to modulate gene expression

The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise to all the proteins ...

Decoding apples: Nitrogen's role in shaping fruit sugar content

Apple quality and yield are significantly affected by nitrogen levels in the soil, which influence various biochemical processes. Insufficient nitrogen can result in poor fruit quality, while excessive nitrogen leads to environmental ...

Study identifies gene targets to combat cognitive decline

Researchers have identified the possible mechanisms by which long-lived mutants of the model system Caenorhabditis elegans are able to maintain learning and memory later in life while some experience cognitive decline.

Gene expression

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as rRNA genes or tRNA genes, the product is a functional RNA.

Several steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-translational modification of a protein. Gene regulation gives the cell control over structure and function, and is the basis for cellular differentiation, morphogenesis and the versatility and adaptability of any organism. Gene regulation may also serve as a substrate for evolutionary change, since control of the timing, location, and amount of gene expression can have a profound effect on the functions (actions) of the gene in the organism.
