Plant Defense against Insect Herbivores
Plants have been interacting with insects for several hundred million years, leading to complex defense approaches against various insect feeding strategies. Some defenses are constitutive while others are induced, although the insecticidal defense compound or protein classes are often similar. Insect herbivory induce several internal signals from the wounded tissues, including calcium ion flux...
متن کاملPlant Growth Hormones in Pinyon Insect Galls
BYERS J. A., BREWER J. W. & DENNA D. W. 1976. Plant growth hormones in pinyon insect galls. Marcellio 39, 125-134. Larvae of the midge Janetiella sp. near J. coloradensis Felt (Diptera: Cecidomyiidae) cause galls at the base of young needles of pinyon Pinus edulis Engelm. Bioassays of extracts from these galls contained as much as 17 times more auxin activity and as much as 21 times more gibber...
متن کاملPlant defense against herbivores: chemical aspects.
Plants have evolved a plethora of different chemical defenses covering nearly all classes of (secondary) metabolites that represent a major barrier to herbivory: Some are constitutive; others are induced after attack. Many compounds act directly on the herbivore, whereas others act indirectly via the attraction of organisms from other trophic levels that, in turn, protect the plant. An enormous...
متن کاملBVOCs: plant defense against climate warming?
Plants emit a substantial amount of biogenic volatile organic compounds (BVOCs) into the atmosphere. These BVOCs represent a large carbon loss and can be up to approximately 10% of that fixed by photosynthesis under stressful conditions and up to 100gCm(-2) per year in some tropical ecosystems. Among a variety of proven and unproven BVOC functions in plants and roles in atmospheric processes, r...
متن کاملHepcidin and Host Defense against Infectious Diseases
Hepcidin is the master regulator of iron homeostasis in vertebrates. The synthesis of hepcidin is induced by systemic iron levels and by inflammatory stimuli. While the role of hepcidin in iron regulation is well established, its contribution to host defense is emerging as complex and multifaceted. In this review, we summarize the literature on the role of hepcidin as a mediator of antimicrobia...
