Metabolomics Profile of Potato Tubers after Phosphite Treatment

Metabolomics Profile of Potato Tubers after Phosphite Treatment

Phosphite (Phi)-based fungicides are used to control the oomycete Phytophthora infestans which causes late blight disease, the most devastating disease in potatoes. In order to examine the effects of Phi-based fungicides on potato tubers through foliar or post-harvest application, a metabolite profiling approach based on gas chromatography coupled to mass spectrometry (GC-MS) has been establish...

Differential expression of genes in potato tubers after wounding.

Tubers of a common tetraploid species of Solanum tuberosum (Granola) were mechanically wounded by slicing. After 18 hr only small differences were detectable in the pattern of the steady-state protein extracted from wounded versus unwounded tubers. In contrast the protein pattern obtained by in vitro translation of mRNA isolated from wounded and unwounded tubers differed significantly. A cDNA l...

Structure of potato tubers formed during spaceflight.

Potato (Solanum tuberosum L. cv. Norland) explants, consisting of a leaf, axillary bud, and small stem segment, were used as a model system to study the influence of spaceflight on the formation of sessile tubers from axillary buds. The explants were flown on the space shuttle Columbia (STS-73, 20 October to 5 November 1995) in the ASTROCULTURE (TM) flight package, which provided a controlled e...

Oil Accumulation in Transgenic Potato Tubers Alters Starch Quality and Nutritional Profile

Plant storage compounds such as starch and lipids are important for human and animal nutrition as well as industry. There is interest in diverting some of the carbon stored in starch-rich organs (leaves, tubers, and cereal grains) into lipids in order to improve the energy density or nutritional properties of crops as well as providing new sources of feedstocks for food and manufacturing. Previ...
