Variation in resource input to plants triggers bottom-up effects on plant-insect herbivore interactions. However, variation in plant intrinsic traits in response to resource availability may modify the bottom-up effects. Furthermore, the consequences also may depend on the feeding strategy of insect herbivores belonging to different feeding...

Plant glutathione peroxidases (Gpx) catalyse the reduction of various peroxides, such as hydrogen peroxide (H2O2), phospholipid hydroperoxides and peroxynitrite, but at the expense of thioredoxins rather than glutathione. A main function of plant Gpxs is the protection of biological membranes by scavenging phospholipid hydroperoxides, but some...

Variation in resource inputs to plants may trigger bottom-up effects on herbivorous insects. We examined the effects of water input: optimal water vs. limited water; water salinity: with vs. without addition of 100 mM NaCl; and their interactions on tomato plants (Solanum lycopersicum), and consequently, the bottom-up effects on the tomato leaf...

Abstract The Periconia fungal genus belongs to the phylum Ascomycota, order Pleosporales, family Periconiaceae. Periconia are found in many habitats, but little is known about their ecology. Several species from this genus produce bioactive molecules. Periconia digitata extracts were shown to be deadly active against the pine wilt nematode....

Prior exposure to microbial-associated molecular patterns or specific chemical compounds can promote plants into a primed state with stronger defence responses. β-aminobutyric acid (BABA) is an endogenous stress metabolite that induces resistance protecting various plants towards diverse stresses. In this study, by integrating BABA-induced...

Abstract Variation in resource inputs to plants may trigger bottom-up effects on herbivorous insects. We examined the effects of water input: optimal water vs . limited water; water salinity: with vs. without addition of 100 mM NaCl; and their interactions on tomato plants ( Solanum lycopersicum ), and consequently, the bottom-up effects on the...
