WebHerbivores are dependent on plants for food, and have coevolved mechanisms to obtain this food despite the evolution of a diverse arsenal of plant defenses against herbivory. Herbivore adaptations to plant defense have been likened to "offensive traits" and consist of those traits that allow for increased feeding and use of a host. Plants, on the other … WebRapid induction may have several benefits: the direct defenses may deter or kill nonspecialized herbivores very quickly, thereby reducing leaf loss. This may not apply to specialist herbivores that can tolerate or detoxify their host plant’s specific defenses (Ali and Agrawal 2012 ).

In: Romeo JT, Saunders JA, Barbosa P (eds) Phytochemical diversity … Plants and herbivores have co-evolved together for 350 million years. Plants have evolved many defense mechanisms against insect herbivory. Such defenses can be broadly classified into two categories: (1) permanent, constitutive defenses, and (2) temporary, inducible defenses. Both types are achieved … Meer weergeven Inducible defenses allow plants to be phenotypically plastic. This may confer an advantage over constitutive defenses for multiple reasons. First, it may reduce the chance that attacking insects adapt to plant … Meer weergeven Systemically induced defences are at least in some cases the result of changes in the transcription rates of genes in a plant. Genes … Meer weergeven Central to the concept of induced defences is the cost involved when stimulating such defences in the absence of insect herbivores.

Web20 mrt. 2024 · Predator-induced changes in the traits of prey species are important components of these nonconsumptive effects. While these are well studied in simplified one-predator one-prey settings, relatively little is known about how kairomones act on prey across heterogeneous aquatic ecosystems with diverse identities of predator and prey.

Perception of elicitors takes place in receptors located either at the cell surface or inside the cell [ 9 ]. This recognition of elicitors triggers … Web15 sep. 2024 · Recent studies have examined how tuber feeding by T. solanivora induced potato plant defenses that affected aboveground herbivore performance and nutrient transport to tubers [12,33]. However, the effect of leaf herbivory during the growing season is often ignored when assessing the level of tuber resistance to the potato tuberworm. diy remove gel nail polish
