The Arabidopsis ATR1 Myb transcription factor controls indolic glucosinolate homeostasis.
Plants derive a number of important secondary metabolites from the amino acid tryptophan (Trp), including the growth regulator indole-3-acetic acid (IAA) and defense compounds against pathogens and herbivores. In previous work, we found that a dominant overexpression allele of the Arabidopsis (Arabidopsis thaliana) Myb transcription factor ATR1, atr1D, activates expression of a Trp synthesis ge...
متن کاملA Myb homologue, ATR1, activates tryptophan gene expression in Arabidopsis.
In Arabidopsis thaliana, tryptophan pathway genes are induced in response to starvation, wounding, and pathogen attack, resulting in increased production of tryptophan and secondary metabolites important for development and defense. The Arabidopsis tryptophan pathway therefore provides an ideal system for elucidating how environmental stimuli are transduced into changes in plant gene expression...
متن کاملNovel insights into the function of Arabidopsis R2R3-MYB transcription factors regulating aliphatic glucosinolate biosynthesis.
Arabidopsis transcription factors, MYB28, MYB29 and MYB76, positively regulate aliphatic glucosinolate (AGSL) biosynthesis. Mutual transcriptional regulation among these MYB genes makes it difficult to elucidate their individual function simply by analyzing knock-out mutants or ectopically overexpressing lines of these genes. In this study, we constructed transgenic lines expressing each MYB ge...
متن کاملOmics-based identification of Arabidopsis Myb transcription factors regulating aliphatic glucosinolate biosynthesis.
Understanding plant metabolism as an integrated system is essential for metabolic engineering aimed at the effective production of compounds useful to human life and the global environment. The "omics" approach integrates transcriptome and metabolome data into a single data set and can lead to the identification of unknown genes and their regulatory networks involved in metabolic pathways of in...
متن کاملMYB transcription factors in Arabidopsis.
The MYB family of proteins is large, functionally diverse and represented in all eukaryotes. Most MYB proteins function as transcription factors with varying numbers of MYB domain repeats conferring their ability to bind DNA. In plants, the MYB family has selectively expanded, particularly through the large family of R2R3-MYB. Members of this family function in a variety of plant-specific proce...
