13. Increased nutritive value of transgenic potato by expressing a nonallergenic seed albumin gene from Amaranthus hypochondriacus
Improvement of nutritive value of crop plants, in particular the amino acid composition, has been a major long-term goal of plant breeding programs. Toward this end, we reported earlier the cloning of the seed albumin gene AmA1 from Amaranthus hypochondriacus. The AmA1 protein is nonallergenic in nature and is rich in all essential amino acids, and the

14. Identification of Granule-Bound Starch Synthase in Potato Tubers 1
Starch granules isolated from potato (Solanum tuberosum L.) tubers were extracted with sodium dodecyl sulfate and the extract was analyzed. A major protein with a molecular weight of 60,000 daltons was detected. This protein was purified by preparative sodium dodecyl sulfate-gel electrophoresis and specific antibodies were prepared. The anti-60-kilodalton an

15. Molecular cloning of a gene encoding a seed-specific protein with nutritionally balanced amino acid composition from Amaranthus.
An albumin with a well-balanced amino acid composition and high levels of the essential amino acids was purified to homogeneity from the mature seeds of Amaranthus hypochondriacus. The amino acid composition of this protein is comparable to the World Health Organization recommended values for a highly nutritional protein. The protein is a 35-kDa monomer with

16. Tissue-Specific and Light-Mediated Expression of the C4 Photosynthetic NAD-Dependent Malic Enzyme of Amaranth Mitochondria.
In the C4 dicotyledonous grain plant amaranth (Amaranthus hypochondriacus), a mitochondrial NAD-dependent malic enzyme (NAD-ME; EC 1.1.1.39) serves a specialized and essential role in photosynthetic carbon fixation. In this study we have examined specialized photosynthetic gene expression patterns for the NAD-ME [alpha] subunit. We show here that the [alpha]

17. Light Induction of Cell Type Differentiation and Cell-Type-Specific Gene Expression in Cotyledons of a C4 Plant, Flaveria trinervia1
In Flaveria trinervia (Asteraceae) seedlings, light-induced signals are required for differentiation of cotyledon bundle sheath cells and mesophyll cells and for cell-type-specific expression of Rubisco small subunit genes (bundle sheath cell specific) and the genes that encode pyruvate orthophosphate dikinase and phosphoenolpyruvate carboxylase (mesophyll c

18. Photosynthetic Gene Expression in Meristems and during Initial Leaf Development in a C4 Dicotyledonous Plant.
Immunolocalization and fluorescent in situ hybridization were used with confocal microscopy to examine patterns of photosynthetic gene expression during initial stages of leaf development in the C4 dicot Amaranthus hypochondriacus. mRNAs encoding the large and small subunit of ribulose-1,5-bisphosphate carboxylase were present in the apical dome and in all c

19. Coordinate, Organ-Specific and Developmental Regulation of Ribulose 1,5-Bisphosphate Carboxylase Gene Expression in Amaranthus hypochondriacus1
The expression of the genes encoding the large subunit (LSU) and small subunit (SSU) of ribulose 1,5-bisphosphate carboxylase (RuBPCase) was examined in roots, stems, cotyledons, and leaves of amaranth during the development of these tissues. The highest accumulation of LSU and SSU polypeptides occurred in cotyledons and leaves. Their steady state levels wer

20. C4 Photosynthetic Gene Expression in Light- and Dark-Grown Amaranth Cotyledons.
The patterns of expression for genes encoding several C4 photosynthetic enzymes were examined in light-grown and dark-grown (etiolated) cotyledons of amaranth (Amaranthus hypochondriacus), a dicotyledonous C4 plant. The large subunit and small subunit of ribulose-1,5-bisphosphate carboxylase (RuBPCase), phosphoenolpyruvate carboxylase (PEPCase), and pyruvate

21. Premature termination of RNA polymerase II mediated transcription of a seed protein gene in Schizosaccharomyces pombe
The poly(A) signal and downstream elements with transcriptional pausing activity play an important role in termination of RNA polymerase II transcription. We show that an intronic sequence derived from the plant seed protein gene (AmA1) specifically acts as a transcriptional terminator in the fission yeast, Schizosaccharomyces pombe. The 3′-end points of m
