Influences of the Populus deltoids seedlings treated with exogenous methyl jasmonate on the growth and development of Lymantria dispar larvae
Lyantria dispar larvae were fed with the leaves of Populus deltoids seedlings exposed to methyl jasmonate (MeJA) for 24 h. The growth and development of the larvae were investigated, and ...

Aldehyde volatiles emitted in succession from mechanically damaged leaves of poplar cuttings
Plant aldehydes are volatiles necessary to defenses against environmental stress. To explore their emissions in response to wounding, we performed gas chromatography-mass spectrometry (GC-MS) on cuttings from ...

Saturated Aldehydes C6–C10 Emitted from Ashleaf Maple (Acer negundo L.) Leaves at Different Levels of Light Intensity, O2, and CO2
Aldehydes, a group of volatile organic compounds (VOCs) often detected in the atmosphere, play a key role in atmospheric chemistry and plant resistance to stresses. We used gas chromatography/mass spectrometry...

Effects of feeding Clostera anachoreta on hydrogen peroxide accumulation and activities of peroxidase, catalase, and ascorbate peroxidase in Populus simonii × P. pyramidalis ‘Opera 8277’ leaves
In response to Clostera anachoreta larvae attack, poplar (Populus simonii × P. pyramidalis ‘Opera 8277’) leaves produced a high level of hydrogen peroxide (H2O2). Histochemical localization revealed that H2O2 was...

Activities of lipoxygenase and phenylalanine ammonia lyase in poplar leaves induced by insect herbivory and volatiles
A study was conducted to explore the defense response in woody plants after insect herbivory. The activities of two enzymes, lipoxygenase (LOX), a key enzyme of jasmonate (JA) pathway, and phenylalanine ammoni...

LiCOI1 mediates the biosynthesis of monoterpenes induced by methyl jasmonate in Lilium ‘Siberia’
As a volatile hormone signal, methyl jasmonate (MeJA) can regulate the biosynthesis of secondary metabolites. But in floral fragrance, the effect and mechanisms of MeJA on monoterpenes, the major components of...
