...iseases in both plants and animals." The study is published in the March 24 issue of the journal Nature. Pruitt and collaborator Susan Lolle found that Arabidopsis in which each parent plant had two copies of a mutant gene could produce progeny that didn't show the parents' deformity, but rather were normal ...

UCSD discovery may help extend life of natural pesticide

...ng the life of this natural pesticide. The study, published February 11 in the journal Science, details the structure of a molecule to which Bt attaches, or "binds," in the lining of the intestines of insects and roundworms. The molecule is a glycolipid--a lipid attached to a tree-like arrangement of sugars. ...

White blood cell waste disposal system plays critical regulatory role
