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 ...
There are physical defense mechanisms that some plants utilize, through structural components, like lignin and the cuticle. [1] The structure of a plant cell wall is incredibly important for wound responses, as both protect the plant from pathogenic infections by preventing various molecules from entering the cell.
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.
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.
Induced systemic resistance (ISR) is a resistance mechanism in plants that is activated by infection. Its mode of action does not depend on direct killing or inhibition of the invading pathogen , but rather on increasing physical or chemical barrier of the host plant. [ 1 ]
Exploiting plants’ defence mechanisms against pests or diseases could help to remove our reliance on toxic pesticides. Plants’ genetic defences may hold key for crop protection, researchers ...
