Elicitor signal transduction leading to production of plant secondary metabolites.

Jian Zhao, L. C. Davis, Robert Verpoorte
Biotechnology advances
2005

Plant secondary metabolites are unique sources for pharmaceuticals, food additives, flavors, and other industrial materials. Accumulation of such metabolites often occurs in plants subjected to… (More)

Nuclear actin and myosin I are required for RNA polymerase I transcription

Vlada V. Philimonenko, Jian Zhao, +8 authors Ingrid Grummt
Nature Cell Biology
2004

The presence of actin and nuclear myosin I (NMI) in the nucleus suggests a role for these motor proteins in nuclear functions. We have investigated the role of actin and nuclear myosin I (NMI) in the… (More)

MATE transporters facilitate vacuolar uptake of epicatechin 3'-O-glucoside for proanthocyanidin biosynthesis in Medicago truncatula and Arabidopsis.

Jian Zhao, Richard A. Dixon
The Plant cell
2009

Expression of the Arabidopsis thaliana MYB transcription factor TRANSPARENT TESTA 2 (TT2) in Medicago trunculata hairy roots induces both proanthocyanidin accumulation and the ATP-dependent… (More)

mTOR-dependent activation of the transcription factor TIF-IA links rRNA synthesis to nutrient availability.

Christine Mayer, Jian Zhao, Xuejun Yuan, Ingrid Grummt
Genes & development
2004

In cycling cells, transcription of ribosomal RNA genes by RNA polymerase I (Pol I) is tightly coordinated with cell growth. Here, we show that the mammalian target of rapamycin (mTOR) regulates Pol I… (More)

beta-arrestin differentially regulates the chemokine receptor CXCR4-mediated signaling and receptor internalization, and this implicates multiple interaction sites between beta-arrestin and CXCR4.

Zhaogu Cheng, Jian Zhao, +5 authors Gang Pei
The Journal of biological chemistry
2000

The chemokine receptor CXCR4 has recently been shown to be a co-receptor involved in the entry of human immunodeficiency virus type 1 into target cells. This study shows that coexpression of… (More)

ERK-dependent phosphorylation of the transcription initiation factor TIF-IA is required for RNA polymerase I transcription and cell growth.

Jian Zhao, Xuejun Yuan, Morten Frödin, Ingrid Grummt
Molecular cell
2003

Phosphorylation of transcription factors by mitogen-activated protein kinase (MAPK) cascades links cell signaling with the control of gene expression. Here we show that growth factors induce rRNA… (More)

Nuclear myosin I acts in concert with polymeric actin to drive RNA polymerase I transcription.

Jing Ye, Jian Zhao, Urs W Hoffmann-Rohrer, Ingrid Grummt
Genes & development
2008

Actin is associated with all three nuclear RNA polymerases and acts in concert with nuclear myosin I (NM1) to drive transcription. Practically nothing is known regarding the state of actin and the… (More)

Wounding stimulates the accumulation of glycerolipids containing oxophytodienoic acid and dinor-oxophytodienoic acid in Arabidopsis leaves.

Christen M. Buseman, Pamela J Tamura, +8 authors Ruth Welti
Plant physiology
2006

Although oxylipins can be synthesized from free fatty acids, recent evidence suggests that oxylipins are components of plastid-localized polar complex lipids in Arabidopsis (Arabidopsis thaliana).… (More)

The Synaptonemal Complex Protein SCP3 Can Form Multistranded, Cross-striated Fibers In Vivo

Li Yuan, Jeanette Pelttari, +6 authors Christer Höög
The Journal of cell biology
1998

The synaptonemal complex protein SCP3 is part of the lateral element of the synaptonemal complex, a meiosis-specific protein structure essential for synapsis of homologous chromosomes. We have… (More)

The 'ins' and 'outs' of flavonoid transport.

Jian Zhao, Richard A. Dixon
Trends in plant science
2010

The sites of plant flavonoid biosynthesis, storage and final function often differ at the subcellular, cell, and even tissue and organ levels. Efficient transport systems for flavonoids across… (More)
