Abstract The resource availability hypothesis predicts that plants adapted to infertile soils have high levels of anti‐herbivore leaf defences. This has been mostly explored for secondary metabolites such as phenolics, whereas it remains underexplored silica‐based We determined concentrations total phenols and silicon (Si) in growing along the 2‐million‐year Jurien Bay chronosequence, exhibiting an extreme gradient soil fertility. found nitrogen (N) limitation on young led a greater expression phenol‐based defences, old, phosphorus (P)‐impoverished favoured Both defence types were negatively correlated at community individual species level. Our results suggest trade‐off among these two strategies based strength type nutrient limitation, thereby opening up new perspectives plant research. study also highlights importance defences under low P supply.

Silicon (Si) is a beneficial mineral that enhances plant protection against abiotic and biotic stresses, including insect herbivores. Si increases mechanical biochemical defenses in variety of species. However, the use agriculture remains poorly adopted despite its widely documented benefits health. In this study, we tested effect supplementation on induction resistance chewing herbivore crops with differential ability to accumulate element. Our model system comprised generalist fall armyworm (FAW) Spodoptera frugiperda three economically important species uptake silicon: tomato (non-Si accumulator), soybean, maize (Si-accumulators). We investigated effects supply herbivory physical defenses, growth using potted plants greenhouse conditions.

Water is essential to plant growth and drives evolution interactions with other organisms such as herbivores. However, water availability fluctuates, these fluctuations are intensified by climate change. How influences plant-herbivore in the future an important question basic applied ecology. Here we summarize synthesize recent discoveries on impact of antiherbivore defense ecology underlying physiological processes. deficit tends enhance resistance escape traits (i.e. early phenology) against herbivory but negatively affects strategies, including indirect tolerance. exceptions sometimes observed specific species pairs. We discuss effect associated plants herbivores from individual community levels how drive evolution. Although stress many abiotic stresses predicted increase intensity frequency due change, identify a significant lack study interactive additional stressors water-plant-herbivore interactions.

Abstract Silicon (Si) can adversely affect insect herbivores, particularly in plants that evolved the ability to accumulate large quantities of Si. Very rapid herbivore‐induced accumulation Si has recently been demonstrated, but level protection against herbivory this affords remains unknown. Brachypodium distachyon , a model hyperaccumulating grass, was exposed chewing herbivore, Helicoverpa armigera, and grown under three conditions: supplied over 34 d (+Si), not (−Si), or once began (−Si → +Si). We evaluated effectiveness each treatment at reducing herbivore performance measured Si‐based defenses phenolics (another form defense often reduced by Si). Although concentrations remained lower, within 72 h exposure Si, −Si +Si were as resistant plants. Both treatments damage growth, increased mandible wear compared −Si. After 6 h, filled cell density plants, 24 reached similar densities although decreased only occurred demonstrate with short‐term rapidly antiherbivore effectively long‐term exposure.
