Airborne signals prime plants against insect herbivore attack.
Green leafy volatiles (GLV), six-carbon aldehydes, alcohols, and esters commonly emitted by plants in response to mechanical damage or herbivory, induced intact undamaged corn seedlings to rapidlyExpand
ABA Is an Essential Signal for Plant Resistance to Pathogens Affecting JA Biosynthesis and the Activation of Defenses in Arabidopsis[W]
TLDR
The results support a model for ABA affecting JA biosynthesis in the activation of defenses against this oomycete, and reveal an unexpected overrepresentation of ABA response elements in promoters of P. irregulare–responsive genes. Expand
Simultaneous analysis of phytohormones, phytotoxins, and volatile organic compounds in plants
Phytohormones regulate the protective responses of plants against both biotic and abiotic stresses by means of synergistic or antagonistic actions referred to as signaling crosstalk. A bottleneck inExpand
An herbivore elicitor activates the gene for indole emission in maize.
TLDR
Gene-sequence analysis indicates that Igl and Bx1 are evolutionarily related to the tryptophan synthase alpha subunit, and IGL's enzymatic properties are similar to BX1, a maize enzyme that serves as the entry point to the secondary defense metabolites DIBOA and DIMBOA. Expand
Circadian Regulation of the PhCCD1 Carotenoid Cleavage Dioxygenase Controls Emission of β-Ionone, a Fragrance Volatile of Petunia Flowers1
TLDR
Quantitative reverse transcription-PCR analysis revealed that PhCCD1 is highly expressed in corollas and leaves, where it constitutes approximately 0.04% and 0.02% of total RNA, respectively, and indicates that Ph CCD1 activity and β-ionone emission are likely regulated at the level of transcript. Expand
Identification of loci affecting flavour volatile emissions in tomato fruits.
TLDR
It was shown that emissions of carotenoid-derived volatiles were directly correlated with the fruit carotENoid content and linked molecular markers should be useful for breeding programmes aimed at improving fruit flavour. Expand
tasselseed1 Is a Lipoxygenase Affecting Jasmonic Acid Signaling in Sex Determination of Maize
TLDR
Application of jasmonic acid to developing inflorescence rescued stamen development in mutant ts1 and ts2 inflorescences, revealing a role for jasMonic acid in male flower development in maize. Expand
Phytohormone-based activity mapping of insect herbivore-produced elicitors
TLDR
The unpredictable nature of elicitor activity between plant species supports the existence of specific receptor-ligand interactions mediating recognition, and E and JA exist as highly conserved and readily quantifiable markers for future discoveries in this field. Expand
The use of vapor phase extraction in metabolic profiling of phytohormones and other metabolites.
TLDR
A novel metabolic profiling approach to the analysis of acidic phytohormones and other metabolites based on a simplistic preparation scheme and analysis by chemical ionization-gas chromatography/mass spectrometry is presented and directions for further method expansion are provided. Expand
Identity, regulation, and activity of inducible diterpenoid phytoalexins in maize
TLDR
The presence of diterpenoid defenses in maize is established and enables a more detailed analysis of their biosynthetic pathways, regulation, and crop defense function. Expand
