Systemically induced defences are at least in some cases the result of changes in the transcription rates of genes in a plant. Genes involved in this process may differ between species, [25] but common to all plants is that systemically induced defences occur as a result of changes in gene expression. The changes in transcription can involve ...
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
We're the Superhumans is a television advert which was produced by Channel 4 to promote its broadcast of the 2016 Summer Paralympics in Rio de Janeiro.. Serving as a follow-up to Meet the Superhumans (which was used to promote the 2012 Summer Paralympics in London), the advert featured people of various backgrounds and disabilities (including several British Paralympic athletes) performing ...
Plant defense against herbivory or host-plant resistance is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites , known as allelochemicals , that influence the behavior, growth, or survival of herbivores.
Plant defensins (formerly gamma-thionins) are a family of primitive, highly stable, cysteine-rich defensins found in plants that function to defend them against pathogens and parasites. [1] Defensins are integral components of the innate immune system and belong to the ancient superfamily of antimicrobial peptides (AMPs).
Plants are constantly exposed to different stresses that result in wounding. Plants have adapted to defend themselves against wounding events, like herbivore attacks or environmental stresses. [1] There are many defense mechanisms that plants rely on to help fight off pathogens and subsequent infections.
The music video was directed by David C. Snyder, and was uploaded unofficially onto YouTube on August 3 2007.. Following the use of "Harder Than You Think" to soundtrack the UK's Channel 4 coverage of the Summer 2012 Paralympics, a music video including clips from the Channel 4 trailer for the Summer 2012 Paralympics was produced by HWIC Filmworks (founded by John Delserone and David C. Snyder ...
Some chemical defenses once thought to be produced by the plant have since been shown to be synthesized by endophytic fungi. The chemical basis of insect resistance in endophyte-plant defense mutualisms has been most extensively studied in the perennial ryegrass and three major classes of secondary metabolites are found: indole diterpenes, ergot alkaloids and peramine.
