Field evaluation of the bacterial volatile derivative 3-pentanol in priming for induced resistance in pepper.
We investigated the ISR capacity of VOCs and derivatives collected from strain IN937a against bacterial spot disease caused by Xanthomonas axonopodis pv. vesicatoria in pepper. Of 15 bacterial VOCs and their derivatives, 3-pentanol, which is a C8 amyl alcohol reported to be a component of sex pherom...
The evolution of ethylene signaling in plant chemical ecology.
We provide a synthesis of the role of ethylene in the context of plant ecology and evolution, and a prospectus for future research in this area. We focus on the regulatory function of ethylene in multi-organismal interactions. In general, plant interactions with different types of organisms lead to...
Symptomless endophytic fungi suppress endogenous levels of salicylic acid and interact with the jasmonate-dependent indirect defense traits ...
We used wild Lima bean (Phaseolus lunatus) plants that were experimentally colonized with one of three strains of natural endophytes (Bartalinia pondoensis, Fusarium sp., or Cochliobolus lunatus) to investigate the effects of fungal colonization on the endogenous levels of salicylic acid (SA) and ja...
Identification and biosynthesis of novel male specific esters in the wings of the tropical butterfly, Bicyclus martius sanaos.
We report the identification and biosynthetic pathways of several novel esters from the wings of male B. martius sanaos. We found that the volatile compounds in this male butterfly were similar to female-produced moth sex pheromones. Components associated with the male wing androconial areas were id...
The inverted phantom giant.
Nectar minerals as regulators of flower visitation in stingless bees and nectar hoarding wasps.
Various nectar components have a repellent effect on flower visitors, and their adaptive advantages for the plant are not well understood. Persea americana (avocado) is an example of a plant that secretes nectar with repellent components. It was demonstrated that the mineral constituents of this nec...
Involvement of a specific chemosensory protein from Bactrocera dorsalis in perceiving host plant volatiles.
Insects have evolved many physiological and behavioral adaptations to recognize external complex chemicals. Olfaction plays an important role in perceiving volatile chemicals, utilizing them to locate host sites, conspecifics, and enemies. Chemosensory proteins (CSPs) are present in high concentrati...
Brassica plant responses to mild herbivore stress elicited by two specialist insects from different feeding guilds.
These results have implications for the understanding of plasticity in plant defenses against herbivores and for the management of Brassica rapa in agroecosystems....
Terpenes tell different tales at different scales: glimpses into the Chemical Ecology of conifer - bark beetle - microbial interactions.
I approach this problem by focusing primarily on one chemical group, terpenes, by emphasizing the curvilinear and threshold-structured basis of most underlying relationships, and by focusing on the system's feedback structure, which can either buffer or amplify relationships across scales....
Real-time monitoring of (E)-β-farnesene emission in colonies of the pea aphid, Acyrthosiphon pisum, under lacewing and ladybird predation.
We present the first long-time monitoring of EBF emission in aphid colonies using real-time monitoring. We used a zNose(TM) to analyze the headspace of colonies of the pea aphid, under lacewing (Neuroptera: Chrysopidae) and ladybird (Coleoptera: Coccinellidae) predation, over 24 hr. We found no emis...
