Cím:	Chemical defence compounds produced by species of the Poaceae family / Péter Makleit, Szilvia Veres
Dátum:	2023
Megjegyzések:	The Poaceae family ranks 5th in the number of species in the Angiosperm phylum with approximately 12,000 species. Its species colonise biomes that are landscape-dominant in different continents (steppe, savannah, prairie, pampas). They are the food of herbivores in these habitats. Their various cultivated species provide essential food for humanity and fodder for our farm animals (e.g. cultivated wheat, rice, maize). Species of this family have also coevolved with their pests and competitors, with both plant species and their natural enemies surviving in a mutually interacting way. During coevolution, plants have evolved different strategies to mitigate damage, in order to repel pests. Morphological and physiological specificities ensure plants' ability to defend themselves. Of particular importance are the compounds produced by species of the Poaceae family to ensure the self-defence of individuals. Some of these compounds are produced continuously by the plant, independently of damage (phytoanticipins), while others are produced in response to damage (phytoalaxins). The effects of these compounds can be quite wide-ranging: repellents, inhibitors of development, transformation, reproduction, colonisation, infection. Some compounds also build up resistance in uninvaded, uninfected parts of the plant (acquired resistance). However, the capacity for self-defence can vary within species, and this is of economic importance in relation to differences in resistance between varieties and hybrids of cultivated species. Cultivars or hybrids with more effective chemical defence show lower levels of damage in their stands, which has a significant impact on the cost of crop protection. Breeding and selection methods can improve resistance, which manifests itself in more effective chemical defenses and significantly reduces environmental stress. Compounds involved in the chemical defence of species of the Poaceae family include a rather diverse group of compounds: without being too exhaustive, these compounds are flavonoids, terpenoids, benzoxazinoids, alkaloids, proteinase inhibitors, oxalic acid, cyanogenic glycosides.
