Journal ArticleDOI
The shikimate pathway and aromatic amino acid biosynthesis in plants.
TL;DR: The pathway organization and the transcriptional/posttranscriptional regulation of the AAA biosynthetic network is summarized and the current limited knowledge of the subcellular compartmentalization and the metabolite transport involved in the plant AAA pathways is identified.
Journal ArticleDOI
Tocopherols Play a Crucial Role in Low-Temperature Adaptation and Phloem Loading in Arabidopsis
TL;DR: Results indicate that tocopherols have a more limited role in photoprotection than previously assumed but play crucial roles in low-temperature adaptation and phloem loading.
Journal ArticleDOI
Highly Divergent Methyltransferases Catalyze a Conserved Reaction in Tocopherol and Plastoquinone Synthesis in Cyanobacteria and Photosynthetic Eukaryotes
Zigang Cheng,Scott E. Sattler,Hiroshi A. Maeda,Yumiko Sakuragi,Donald A. Bryant,Dean DellaPenna +5 more
TL;DR: In vivo analyses of vte3 mutants and the corresponding homozygous Synechocystis sp PCC6803 sll0418::aphII mutant revealed important differences in enzyme redundancy, the regulation of tocopherol synthesis, and the integration of toCopherol and PQ biosynthesis in cyanobacteria and plants.
Journal ArticleDOI
An alternative pathway contributes to phenylalanine biosynthesis in plants via a cytosolic tyrosine:phenylpyruvate aminotransferase
Heejin Yoo,Joshua R. Widhalm,Yichun Qian,Hiroshi A. Maeda,Hiroshi A. Maeda,Bruce R. Cooper,Amber Jannasch,Itay Gonda,Efraim Lewinsohn,David Rhodes,Natalia Dudareva +10 more
TL;DR: It is shown that plants also utilize a microbial-like phenylpyruvate pathway to produce phenylalanine, and flux through this route is increased when the entry point to the arogenate pathway is limiting, uncovering another level of complexity in the plant aromatic amino acid regulatory network.
Journal ArticleDOI
Tocopherol functions in photosynthetic organisms
Hiroshi A. Maeda,Dean DellaPenna +1 more
TL;DR: The cell wall development of phloem transfer cells under cold conditions is, however, severely impaired in mature leaves of tocopherol-deficient mutants, indicating that tocop herols are required for proper adaptation ofphloem loading at low temperatures.
