Ixodes ricinus Strains in Europe

Zentralblatt für Bakteriologie, 1998
An analysis of cuticular hydrocarbons (CH) of unfed adult Ixodes ricinus ticks collected throughout Europe showed that there are 10 distinct I. ricinus groups. Studies on the seasonal and annual consistency of CH composition and possible effects of host and environmental factors suggested that CHs may be used as a genuine genetic marker for I. ricinus.

Micropropagation of Ricinus communis

Journal of Plant Physiology, 1995
Summary An efficient micropropagation protocol was developed for Ricinus communis , which is a recalcitrant plant species. For this purpose, apical and axillary bud explants of two months old plantlets were cultured on modified MS medium. Shoot regeneration was optimal with 1000 nM BAP and 30 g · L -1 sucrose in the medium. Addition of NAA affected

Phloem transport of sulfur in Ricinus

Planta, 1982
Mature 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, 2001
The 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, 1981
The 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 ...

Ricinus communis L., 1753

2015
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.
