Cotyledon Excision and Flowering in Pisum Sativum

Genetic Regulation of Flowering in Grafts on Pisum sativum L.

Lf, E, Sn, and Hr are major loci that condition the flowering and photoperiod responses of Pisum sativum L. Genetic lines containing the dominant alleles of these loci are characterized by flowering in long days, but having a prolonged (>50 node) vegetative phase in short days. A representative of this class, response type G, was used as a receptor in short days for donors of other flowering re...

DNA methylase from Pisum sativum.

DNA methylase activity was detected in nuclei from pea shoots. The enzyme can only be extracted by low-salt treatment if the nuclei are pretreated with micrococcal nuclease. Only a single enzyme was detected, and it was purified to a specific activity of 1620 units/mg of protein. It has an Mr of 160,000 on gel filtration and SDS/PAGE. Pea DNA methylase methylates cytosine in all four dinucleoti...

The isoperoxidases of Pisum sativum.

The heterogeneity of the peroxidases in peas was examined by starch gel electrophoresis. Comparisons were made between tall and dwarf cultivars and among organ systems developed in light and darkness. Isoperoxidase bands could be grouped as cathodic, anodic and near-neutral (at pH 9.0) types. The cathodic set stained well with guaiacol oxidation products whereas some anodic bands reacted prefer...

Pea, Pisum sativum, and Its Anticancer Activity

Pisum sativum (Family: Fabaceae), as known as green pea or garden pea, has long been important in diet due to its content of fiber, protein, starch, trace elements, and many phytochemical substances. It has been shown to possess antibacterial, antidiabetic, antifungal, anti-inflammatory, antihypercholesterolemia, and antioxidant activities and also shown anticancer property. Its nonnutritive bi...
