Phloem transport of sulfur in Ricinus
Planta, 1982Mature leaves of Ricinus communis fed with (35)SO 4 (2-) in the light export labeled sulfate and reduced sulfur compounds by phloem transport. Only 1-2% of the absorbed radiosulfur is exported to the stem within 2-3 h, roughly 12% of (35)S recovered was in reduced form.

Lipolytic activity of ricin from Ricinus sanguineus and Ricinus communis on neutral lipids
Biochemical Journal, 2001The present study was carried out with a view of determining ricin lipolytic activity on neutral lipids in emulsion and in a membrane-like model. Using 2,3-dimercapto-1-propanol tributyrate (BAL-TC4) as substrate, the lipolytic activity of ricin was found to be proportional to ricin and substrate concentrations, with an apparent Km (Km,app) of 2.4mM, a

Pachytene variations in Ricinus
Genetica, 1981The pachytene complement in microsporocytes was compared among ten races of Ricinus communis L., the castor plant (2n=20). Four kinds of pachytene variations were observed: (1) variation in degree of spreading of the chromosomes; (2) variation in degree of attenuation of heterochromatin; (3) variation in morphology, which appeared to be restricted to ...

Effect of lectins on Ricinus invertase
Phytochemistry, 1991Abstract Ricinus communis invertase is activated by a number of macromolecules including proteins and lectins. This invertase is a glycoprotein containing ca 45% of sugars in the molecule. The activation by lectins is produced through the formation of a complex with the invertase sugars.

Ricinus communis ist ein nicht frostharter Baum. Der Wunderbaum ist sehr schnellwachsend und erreicht Hohen bis 13 m und Durchmesser bis zu 30 cm. Der Stamm ist grun bis braun, rotlich oder glanzend in der Jugend. Der Name Rizinus geht vermutlich auf das hebraische Wort fur rundlich zuruck, womit die Form der Samen beschrieben wurde.
