“…High soil N availability generally increases leaf N concentration, due to enhancement in N uptake by plants (Hobbie et al 2001;Cao et al 2008, W. Dong et al 2011. Similar to these results, N fertilization significantly increased foliar N a and N m concentrations of both species in the present study.…”

The effects of soil warming and nitrogen (N) fertilization on nitrogen metabolism and nutrient status of Picea asperata Mast. and Pinus tabulaformis Carr. seedlings were studied in this paper. Infrared heaters increased monthly average soil and air temperature by 2.6 and 2.1 C above the ambient, respectively. Ammonium nitrate (NH 4 NO 3 ) was added in an amount equivalent to an additional 25 g N m À2 a À1. Interestingly, soil warming, N fertilization, and their combination decreased foliar phosphorus (P) and magnesium (Mg) concentration of Picea asperata seedlings, but increased them in Pinus tabulaformis seedlings. Moreover, the combination of warming and N fertilization induced greater increments of amino acid, area-based N concentration and mass-based N concentration, manganese (Mn) and zinc (Zn), and further decreased P and calcium (Ca) concentration in Picea asperata seedlings. However, this phenomenon was not observed in Pinus tabulaformis seedlings. These results indicated that Picea asperata seedlings are more sensitive to the combination of warming and N fertilizer than Pinus tabulaformis seedlings.

“…Leaf N content was often enhanced by N addition due to higher soil N availability (Hobbie et al 2001;Cao et al 2008). Leaf N content of P. tabulaeformis seedlings was increased by N fertilization regardless of warming.…”

“…Photosynthesis provides ATP and carbon substrate (glyceraldehyde-3-phosphate or pyruvate) for isoprene synthesis. Increased foliar biomass in AM plants results in greater photosynthetic capacity and thus increased production of total photosynthates required for terpenoid biosynthesis (Niinemets et al, 2002;Cao et al, 2008;Hofmeyer et al, 2010). However, P nutrition alone fails to explain terpenoid accumulation in AM fungus-colonized plants (Copetta et al, 2006;Khaosaad et al, 2006;Rydlov a et al, 2016).…”

Background Plants, though sessile, employ various strategies to defend themselves against herbivorous insects and convey signals of an impending herbivore attack to other plant(s). Strategies include the production of volatiles that include terpenoids and the formation of symbiotic associations with fungi, such as arbuscular mycorrhiza (AM). This constitutes a two-pronged above-ground/below-ground attack-defence strategy against insect herbivores.Scope Terpenoids represent an important constituent of herbivore-induced plant volatiles that deter herbivores and/or attract their predators. Terpenoids serve as airborne signals that can induce defence responses in systemic undamaged parts of the plant and also prime defence responses in neighbouring plants. Colonization of roots by AM fungi is known to influence secondary metabolism in plants; this includes alteration of the concentration and composition of terpenoids, which can boost both direct and indirect plant defence against herbivorous insects. Enhanced nutrient uptake facilitated by AM, changes in plant morphology and physiology and increased transcription levels of certain genes involved in the terpenoid biosynthesis pathway result in alterations in plant terpenoid profiles. The common mycorrhizal networks of external hyphae have added a dimension to the two-pronged plant defence strategy. These act as conduits to transfer defence signals and terpenoids.Conclusion Improved understanding of the roles of terpenoids in plant and AM defences against herbivory and of interplant signalling in natural communities has significant implications for sustainable management of pests in agricultural ecosystems.
