Phylogenetics of Cucumis (Cucurbitaceae) [PDF]
, 2007 Background: Melon, Cucumis melo, and cucumber, C. sativus, are among the most widely cultivated crops worldwide. Cucumis, as traditionally conceived, is geographically centered in Africa, with C. sativus and C.

Congruence of chloroplast- and nuclear-encoded DNA sequence variations used to assess species boundaries in the soil microalga Heterococcus (Stramenopiles, Xanthophyceae). [PDF]
, 2013 BackgroundHeterococcus is a microalgal genus of Xanthophyceae (Stramenopiles) that is common and widespread in soils, especially from cold regions. Species are characterized by extensively branched filaments produced when grown on agarized culture medium.

Optimization of macromolecular prodrugs of the antitumor antibiotic adriamycin [PDF]
, 1985 In our earlier work [10] on aminoribosyl-bound prodrugs of adriamycin (ADR) using poly(α-l-glutamic acid) (PGA) grafted in high yield (90–100 mol.%) with various peptide spacers as a plasma-soluble macromolecular carrier we observed rather low cytotoxic ...

Restriction analysis of spacers in ribosomal DNA of Drosophila melanogaster
Nucleic Acids Research, 1979 The sequence arrangement of ribosomal DNA (rDNA) spacers in Drosophila melanogaster was analyzed with restriction endonucleases. Spacers, derived from cloned rDNA repeats and from uncloned purified rDNA, are internally repetitive, as demonstrated by the regular 250 base pairs interval between sites recognized by the enzyme Alu I.
