Two-component systems are well-integrated into developmental signaling pathways in plants, but the genes probably originated from lateral gene transfer from chloroplasts. [3] An example is the chloroplast sensor kinase (CSK) gene in Arabidopsis thaliana , derived from chloroplasts but now integrated into the nuclear genome.
To date, work on induction of plant systemic resistance has shown that inducing plant system resistance work has important implications for basic and applied research. Induced resistance applications in melons, tobacco, bean, potato, and rice have achieved significant success. Over the past decade, the study of induced system resistance has ...
Systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen.SAR is analogous to the innate immune system found in animals, and although there are many shared aspects between the two systems, it is thought to be a result of convergent evolution. [1]
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.
Biosignals may also refer to any non-electrical signal that is capable of being monitored from biological beings, such as mechanical signals (e.g. the mechanomyogram or MMG), acoustic signals (e.g. phonetic and non-phonetic utterances, breathing), chemical signals (e.g. pH, oxygenation) and optical signals (e.g. movements).
A biochemical cascade, also known as a signaling cascade or signaling pathway, is a series of chemical reactions that occur within a biological cell when initiated by a stimulus.
In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor, and the effector.
Research suggests that evolutionary repurposing of the jasmonate signaling pathway, which mediates defense against herbivores in noncarnivorous plants, has supported the evolution of plant carnivory. Jasmonates can be used to signal the closing of traps and to control the release of enzymes and nutrient transporters which are used in plant ...
