Proteomic analysis of dehydroascorbate reductase transgenic potato plants

Molecular Properties and Functional Divergence of the Dehydroascorbate Reductase Gene Family in Lower and Higher Plants

Dehydroascorbate reductase (DHAR), which reduces oxidized ascorbate, is important for maintaining an appropriate ascorbate redox state in plant cells. To date, genome-wide molecular characterization of DHARs has only been conducted in bryophytes (Physcomitrella patens) and eudicots (e.g. Arabidopsis thaliana). In this study, to gain a general understanding of the molecular properties and functi...

Proteomic analysis of differentially synthesized proteins in potato purple top phytoplasma-infected tomato plants

Potato purple top (PPT) is an emerging potato disease complex. The etiological agents of PPT are phloem-inhabiting, cell wallless bacteria known as phytoplasmas. Tomato is an alternative host of these phytoplasmas. PPT phytoplasma-infected tomato plants exhibit symptoms including abnormal foliage development and formation of “big buds”. In the present study, twodimensional gel electrophoresis (...

Fructan as a New Carbohydrate Sink in Transgenic Potato Plants.

Fructans are polyfructose molecules that function as nonstructural storage carbohydrates in several plant species that are important crops. We have been studying plants for their ability to synthesize and degrade fructans to determine if this ability is advantageous. We have also been analyzing the ability to synthesize fructan in relation to other nonstructural carbohydrate storage forms like ...

Molecular Analysis of Transgenic Plants

Function of phytochrome A in potato plants as revealed through the study of transgenic plants.

We have generated transgenic potato plants (Solanum tuberosum) containing the potato phytochrome protein encoded by the PHYA gene cDNA (phyA) in sense or antisense orientation under the control of the 35S cauliflower mosaic virus promoter. Plants with increased and decreased phyA levels were analyzed. When grown under white light, development and growth of sprouts and plants were barely disting...
