Organ-Specific Arabinogalactan-Proteins of Lycopersicon peruvianum (Mill) Demonstrated by Crossed Electrophoresis

Organ-Specific Arabinogalactan-Proteins of Lycopersicon peruvianum (Mill) Demonstrated by Crossed Electrophoresis.

Extracts of style, petal, leaf, petiole, stem, and callus derived from stems of wild tomato (Lycopersicon peruvianum) contain characteristic sets of arabinogalactan-proteins. This is demonstrated by crossed electrophoresis in which Yariv reagent, which specifically binds to and precipitates arabinogalactan-proteins, is incorporated into the second gel.

Cloning and nucleotide sequence of two S-RNases from Lycopersicon peruvianum (L.) Mill.

Self-incompatibility is one of the mechanisms that has evolved to encourage outbreeding in flowering plants (de Nettancourt, 1977). One particular type of self-incompatibility, gametophytic self-incompatibility, is found in members of Solanaceae, such as the wild tomato, Lycopersicon peruvianum (Mau et al., 1986). Gametophytic self-incompatibility in L. peruvianum is controlled by a single locu...

Caeruloplasmin as demonstrated by starch gel electrophoresis.

Starch gel electrophoresis has demonstrated that graded concentrations of sodium sulphate do not precipitate the serum globulins in any reasonable degree of purity. The use of this form of electrophoresis has shown that caeruloplasmin is associated with a globulin in the Fa(2) position.This technique can be employed as a screening test for patients suspected of suffering from hepatolenticular d...

Tissue Specific Expression of Human Calcitonin Gene in Potato Tubers by an Organ Specific Promoter

To increase the production level of heterologous proteins in plants, strategies such as choice of strongerpromoters, optimization of codon usage and specific localization of foreign proteins are of major concern.Calcitonin (CT), a 32 amino acid polypeptide is a powerful and specific inhibitor of bone resorption and isused to treat several human diseases. Calcitonin activity is...
