TL;DR: In this paper, a comprehensive analysis of the metabolome and transcriptome of Arabidopsis thaliana over-expressing the PAP1 gene encoding an MYB transcription factor was performed for the identification of novel gene functions involved in flavonoid biosynthesis.
Journal ArticleDOI
Loss of anthocyanins in red-wine grape under high temperature
TL;DR: The data suggest that the decrease in anthocyanin accumulation under high temperature results from factors such as anthocynin degradation as well as the inhibition of mRNA transcription of the anthocianin biosynthetic genes.
Journal ArticleDOI
Elucidation of Gene-to-Gene and Metabolite-to-Gene Networks in Arabidopsis by Integration of Metabolomics and Transcriptomics
Masami Yokota Hirai,Marion Klein,Yuuta Fujikawa,Mitsuru Yano,Dayan B. Goodenowe,Yasuyo Yamazaki,Shigehiko Kanaya,Yukiko Nakamura,Yukiko Nakamura,Masahiko Kitayama,Hideyuki Suzuki,Nozomu Sakurai,Daisuke Shibata,James G. Tokuhisa,Michael Reichelt,Jonathan Gershenzon,Jutta Papenbrock,Kazuki Saito +17 more
TL;DR: It is suggested that regulatory metabolites and transcriptional factor genes can be identified by this approach, based on the assumption that they cluster with the downstream genes they regulate.
Journal ArticleDOI

TL;DR: Based on the comprehensive characterization of tomato fruit metabolites, it is demonstrated that metabolite annotation facilitates the systematic analysis of unknown metabolites and biological interpretation of their relationships, which provide a basis for integrating metabolite information into the system-level study of plant biology.
Journal ArticleDOI
Convergent evolution in the BAHD family of acyl transferases: identification and characterization of anthocyanin acyl transferases from Arabidopsis thaliana
Jie Luo,Yasutaka Nishiyama,Yasutaka Nishiyama,Christine Fuell,Goro Taguchi,Katherine A. Elliott,Lionel Hill,Yoshikazu Tanaka,Masahiko Kitayama,Mami Yamazaki,Paul Bailey,Adrian J. Parr,Anthony J. Michael,Kazuki Saito,Cathie Martin +14 more
TL;DR: It is shown that the activities of these enzymes influence the stability of anthocyanins at neutral pH, and some acylations also affect the anthokyanin absorption maxima, which makes the BAHD acyl transferases suitable tools for engineering anthochenins for an improved range of biotechnological applications.
