Deceptive chemical signals induced by a plant virus attract insect vectors to inferior hosts
TLDR
CMV appears to attract vectors deceptively to infected plants from which they then disperse rapidly, a pattern highly conducive to the nonpersistent transmission mechanism employed by CMV and very different from the pattern previously reported for persistently transmitted viruses that require sustained aphid feeding for transmission.

Within-plant signalling via volatiles overcomes vascular constraints on systemic signalling and primes responses against herbivores.
TLDR
Self-signalling via volatiles is consistent with the short distances over which plant response to airborne cues has been observed to occur and has apparent benefits for emitting plants, suggesting that within-plant signalling may have equal or greater ecological significance than signalling between plants.

Priming defense genes and metabolites in hybrid poplar by the green leaf volatile cis-3-hexenyl acetate.
TLDR
Woody plants can detect and use z3HAC as a signal to prime defenses before actually experiencing damage, and GLVs may have important ecological functions in arboreal ecosystems.

Plant Defense Priming against Herbivores: Getting Ready for a Different Battle1
TLDR
The induction of direct and indirect plant strategies in response to herbivore feeding or pathogen infection is studied.

Volatile Chemical Cues Guide Host Location and Host Selection by Parasitic Plants
TLDR
It is demonstrated that the parasitic plant Cuscuta pentagona (dodder) uses volatile cues for host location and seedlings exhibit directed growth toward nearby tomato plants and toward extracted tomato-plant volatiles presented in the absence of other cues.

Gall insects can avoid and alter indirect plant defenses.
TLDR
Infestation by E. solidaginis appeared to suppress volatile responses to subsequent attack by the generalist caterpillar, which may reduce the predation risk for the gall inducer and the subsequent herbivore, and could influence community-level dynamics, including the distribution of herbivorous insect species associated with S. altissima.

Comparisons and Contrasts in Host-Foraging Strategies of Two Larval Parasitoids with Different Degrees of Host Specificity
TLDR
In wind-tunnel experiments, it is investigated how systemically released herbivore-induced volatiles were used by the generalist parasitoid, Cotesia marginiventris (Cresson) and the specialist,Microplitis croceipes ( Cresson), and the relative influence of these volatile as compared to other signals emitted in the host orientation of the two parasitoids.

Jasmonate- and salicylate-mediated plant defense responses to insect herbivores, pathogens and parasitic plants.
TLDR
A review is given of recent work on these defense signaling molecules with relevance for understanding their role in plant responses to parasitism.

Parasitism by Cuscuta pentagona sequentially induces JA and SA defence pathways in tomato.
TLDR
These findings provide the first documentation of plant hormonal signalling induced by a parasitic plant and show that tomato responses to C. pentagona display characteristics similar to both herbivore- and pathogen-induced responses.

Parasitism by Cuscuta pentagona Attenuates Host Plant Defenses against Insect Herbivores1
TLDR
It is found that parasitized plants were capable of producing induced volatiles when experimentally treated with JA, indicating that resource depletion by the parasite does not fully explain the observed attenuation of volatile response to herbivore feeding.
