Many of these plants have been investigated scientifically for antimicrobial activity, and some plant products have been shown to inhibit the growth of pathogenic microorganisms. [27] A number of these agents appear to have structures and modes of action that are distinct from those of the antibiotics in current use, suggesting that cross ...
Capsidiol is a phytoalexin produced by certain plants in response to pathogenic attack.. Phytoalexins are antimicrobial substances, some of which are antioxidative as well. They are defined not by their having any particular chemical structure or character, but by the fact that they are defensively synthesized de novo by plants that produce the compounds rapidly at sites of pathogen infection.
Plants synthesize a variety of phytochemicals, but most are derivatives: [9] Alkaloids are a class of chemical compounds containing a nitrogen ring. Alkaloids are produced by a large variety of organisms, including bacteria, fungi, plants, and animals, and are part of the group of natural products (also called secondary metabolites).
Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [2] [3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators. [2]
Extracts of the plant are used to ease the symptoms of malaria. The boiled juice or a tea made from the leaves or the whole plant is taken to relieve fever and other symptoms. It is also used for dysentery, pain, and liver disorders. [143] A tea of the leaves is taken to help control diabetes in Peru and other areas. [144]
Plant defensins elicit diverse antimicrobial properties, including antibacterial, [2] and antifungal [26] activities. The modes of action of different defensins depend on the type of organism and specific molecular targets, [ 27 ] [ 2 ] although their exact mechanisms of action vary.
Plants with transgenic/GM disease resistance against insect pests have been extremely successful as commercial products, especially in maize and cotton, and are planted annually on over 20 million hectares in over 20 countries worldwide [49] (see also genetically modified crops). Transgenic plant disease resistance against microbial pathogens ...
Plants are capable of producing and synthesizing diverse groups of organic compounds and are divided into two major groups: primary and secondary metabolites. [9] Secondary metabolites are metabolic intermediates or products which are not essential to growth and life of the producing plants but rather required for interaction of plants with their environment and produced in response to stress.
