Integrated Metabolomics and Selection Signal Analysis Provide Insights Into the Selection for Flavonol Biosynthesis Associated With Lettuce Quality Improvement

Plant Biotechnology Journal, EarlyView.
ABSTRACT Lettuce is a critical leafy vegetable consumed worldwide and is a substantial dietary source of health‐promoting compounds. Exploring changes in metabolism during lettuce domestication under artificial selection conditions is important to facilitate further breeding and cultivation for quality improvement.

HPLC-ESI-MS/MS analysis of oxidized di-caffeoylquinic acids generated by metalloporphyrin-catalyzed reactions

Química Nova, 2008
This paper reports an HPLC-ESI-MS/MS investigation on the oxidation of 3,5- and 4,5- dicaffeoylquinic acid using iron(III) tetraphenylporphyrin chloride as catalyst. Two major mono-oxidised products of the quinic acid moiety have been identified for both

A MYB‐Related Transcriptional Module Cooperatively Represses Xylem Development in Poplar

Plant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors play crucial roles in regulating plant growth and development, but the functions of the MYB‐related subfamily in woody plants remain poorly understood. In this study, we characterized PagMYBR028, an MYB‐related transcription factor from poplar ‘84 K’ (Populus alba × Populus glandulosa), which was predominantly ...

Podospermic acid, 1,3,5-tri-O-(7,8-dihydrocaffeoyl) quinic acid from Podospermum laciniatum (Asteraceae) [PDF]

, 2005
A phytochemical investigation of Podospermum laciniatum (L.) DC. (Asteraceae) yielded the new quinic acid derivative podospermic acid (1,3,5-tridihydrocaffeoylquinic acid), which was named after the genus it was isolated from.

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

Total synthesis of 3,5-O-dicaffeoylquinic acid and its derivatives [PDF]

, 2011
We report the first total synthesis of 3,5-O-dicaffeoylquinic acid and its derivatives, 3,5-O-diferuloylqui- nic acid and 3,5-(3,4-dimethoxycinnamyl)quinic acid, in a nine-step sequence. The key step involves Knoevenagel condensations between vanillin, 3,

Geometrical isomerization of hydroxycinnamic acid under UV‐light: Structural plasticity as a driver of metabolite complexity

Photochemistry and Photobiology, EarlyView.
UV irradiation drives metabolite complexity through photoisomerization of hydroxycinnamic acid‐containing compounds in plants. The olefin functional group of hydroxycinnamic acid enables structural plasticity through trans/cis isomerization. Multiple chromophores within a molecule can amplify UV‐induced transformations.
