Lectins are present in microorganisms, plants and animals and have attracted great interest due to their varied physiological roles in cell agglutination, anti-tumour, immunomodulatory, antifungal and antiviral effects. Legume lectins are important to the pharmaceuticals but they are produced in low amounts in the plant seeds. Moreover, the genes controlling these proteins are conditionally act...

The ability of green pea (Pisum sativum var. Alaska) stem sections to elongate in response to H(+) has been reinvestigated. Contrary to the conclusions of Barkley and Leopold, (Plant Physiol. 1973. 52: 76-78) these sections elongate in response to H(+) whenever H(+) entry through the cuticle is facilitated by slits, holes, or removal. Both live and frozen-thawed sections can undergo acid-induce...

Introduction Grass pea consumption leads to neurolathyrism and a safer use of this environmentally adaptable crop needs cultivars with decreased neurotoxin levels. Were they cross-compatible, grass peas would be useful genetic resources for disease resistance breeding of peas (Pisum sativum L.). In vitro selection (9) and gene transfer may provide grass peas better adapted for consumption, whil...

Cloning and sequencing of two cDNAs from mRNA of maturing pea (Pisum sativum) seeds allowed the deduction of the complete amino acid sequence of a lipoxygenase polypeptide which is most similar to that of soya-bean lipoxygenase 2. The predicted Mr of this polypeptide is 97134, and its sequence permits comparisons between the lox2-type and the lox3-type lipoxygenase isoforms from pea and soya be...

We observed no exchange between deuterated ethylene (C(2)D(4)) and the hydrogen of pea seedlings (Pisum sativum L. cv. Alaska). This suggests that bonding forces in which exchange could readily occur are not important in the physiological action of ethylene. Deuterated ethylene was just as effective as normal ethylene in inhibiting the growth of pea root sections. These results indicate that sp...

A wild relative of the garden pea, formerly called Pisum sativum L., but now included in genus Lathyrus, is illustrated, and its relationship to cultivated peas discussed. Recent studies DNA Lathyrus have led change name for this common species.

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...

Diamine oxidase was prepared from pea (Pisum sativum) seedlings by a new purification procedure involving two h.p.l.c. steps. We studied the optical and electrochemical properties of the homogeneous enzyme and also analysed the hydrolysed protein by several methods. The data presented here suggest that the carbonyl cofactor of diamine oxidase is firmly bound pyrroloquinoline quinone.
