Plastidial Thioredoxin z Interacts with Two Fructokinase-Like Proteins in a Thiol-Dependent Manner: Evidence for an Essential Role in Chloroplast Development in Arabidopsis and Nicotiana
This study describes a thioredoxin isoform (TRX z) that is crucial in plant development and functions in regulation of the plastid-encoded RNA polymerase. It shows that at least one TRX z target isExpand

Identification of a Novel Adenine Nucleotide Transporter in the Endoplasmic Reticulum of Arabidopsis[W]
Many metabolic reactions in the endoplasmic reticulum (ER) require high levels of energy in the form of ATP, which is important for cell viability. Here, we report on an adenine nucleotideExpand

TAXONOMIC REVISION OF THE FAMILY CLOSTEROVIRIDAE WITH SPECIAL REFERENCE TO THE GRAPEVINE LEAFROLL-ASSOCIATED MEMBERS OF THE GENUS AMPELOVIRUS AND THE PUTATIVE SPECIES UNASSIGNED TO THE FAMILY
New insights into the genetic structure and variability of grapevine leafroll-associated viruses (GLRaVs) gained through worldwide efforts in the last decade or so, and the production and use of newExpand

Diurnal and Light-Regulated Expression of AtSTP1 in Guard Cells of Arabidopsis1
Guard cell chloroplasts are unable to perform significant photosynthetic CO2 fixation via Rubisco. Therefore, guard cells depend on carbon supply from adjacent cells even during the light period. DueExpand

An Archaebacterial Topoisomerase Homolog Not Present in Other Eukaryotes Is Indispensable for Cell Proliferation of Plants
Plants, in contrast to other eukaryotes, possess not only homologs of subunit A (AtSPO11-1, 2, 3) but also of subunit B (AtTOP6B) of the archaebacterial topoisomerase VI. AtTOP6B and AtSPO11-3 areExpand

Regulation of carbohydrate partitioning during the interaction of potato virus Y with tobacco.
Abstract To test whether carbohydrates may play a signalling function during plant pathogenesis, we investigated the interaction between tobacco and potato virus Y (PVY(N)). Four days after PVY(N)Expand

Hydrogen peroxide and expression of hipI-superoxide dismutase are associated with the development of secondary cell walls in Zinnia elegans.
A special form of a CuZn-superoxide dismutase with a high isoelectric point (hipI-SOD; EC 1.15.1.1) and hydrogen peroxide (H2O2) production were studied during the secondary cell wall formation ofExpand

Characterization of a virus infecting Citrus volkameriana with citrus leprosis-like symptoms.
A Citrus volkameriana tree displaying symptoms similar to citrus leprosis on its leaves and bark was found in Hawaii. Citrus leprosis virus C (CiLV-C)-specific detection assays, however, wereExpand

RNAi-Mediated Tocopherol Deficiency Impairs Photoassimilate Export in Transgenic Potato Plants1
Tocopherols (vitamin E) are lipophilic antioxidants presumed to play a key role in protecting chloroplast membranes and the photosynthetic apparatus from photooxidative damage. AdditionalExpand

Heterosis manifestation during early Arabidopsis seedling development is characterized by intermediate gene expression and enhanced metabolic activity in the hybrids.
Heterosis-associated cellular and molecular processes were analyzed in seeds and seedlings of Arabidopsis thaliana accessions Col-0 and C24 and their heterotic hybrids. Microscopic examinationExpand
