Phloem sap proteins from Cucurbita maxima and Ricinus communis have the capacity to traffic cell to cell through plasmodesmata.
In angiosperms, the functional enucleate sieve tube system of the phloem appears to be maintained by the surrounding companion cells. In this study, we tested the hypothesis that polypeptides present within the phloem sap traffic cell to cell from the companion cells, where they are synthesized, into the sieve tube via plasmodesmata. Coinjection of fluorescently labeled dextrans along with size...
متن کاملOverview on Cucurbita Maxima Seed
Pumpkin ( cucurbita maxima ) belongs to cucurbitaceae which include pumpkin, gourds, melons and squashes. They are characterized by their seed oil. Pumpkin plant has been grown since the earliest history of mankind 1 . ( Brucher – 1989 ). Pumpkin are grown around the world for variety of agricultural purposes, the seeds show anti helmintic, taenicide diuretic, cardio tonic, anti-inflammatory, a...
متن کاملP Protein in the Phloem of Cucurbita
Light and electron microscopical observations of the cells of the phloem of Cucurbita maxima have shown that two distinct types of P-protein bodies are formed: a larger type which arises as fine fibrils and a smaller type which apparently arises as groups of tubules. The tubules of the smaller type of body measure 242 +/- 3.6 (SE) A (n = 48) and appear morphologically identical with the P1-prot...
متن کاملRemote-controlled stop of phloem mass flow by biphasic occlusion in Cucurbita maxima
The relationships between damage-induced electropotential waves (EPWs), sieve tube occlusion, and stop of mass flow were investigated in intact Cucurbita maxima plants. After burning leaf tips, EPWs propagating along the phloem of the main vein were recorded by extra- and intracellular microelectrodes. The respective EPW profiles (a steep hyperpolarization/depolarization peak followed by a prol...
متن کاملRapid affinity-purification and physicochemical characterization of pumpkin (Cucurbita maxima) phloem exudate lectin.
The chito-oligosaccharide-specific lectin from pumpkin (Cucurbita maxima) phloem exudate has been purified to homogeneity by affinity chromatography on chitin. After SDS/PAGE in the presence of 2-mercaptoethanol, the pumpkin phloem lectin yielded a single band corresponding to a molecular mass of 23.7 kDa, whereas ESI-MS (electrospray ionization MS) gave the molecular masses of the subunit as 2...
