Nitrate assimilation by plants provides an excellent system for demonstrating control of gene
expression in a eukaryotic organism. Describes an assay method that allows students to …

In vitro translation systems were prepared with supernatant factors from wheat germ and 80S
ribosomes from wheat germ, barley embryos, watermelon cotyledons, pea cotyledons, and …

During seed development, various storage proteins and hydrolases accumulate in specialized
storage vacuoles, the protein bodies, via an elaborate intracellular transport system …

The toxic (A) and cell binding (B) chains of the castor bean lectins ricin and Ricinus communis
agglutinin are synthesized together in the form of single polypeptide precursors. The …

The amounts of the two lectins (ricin and Ricinus communis agglutinin) in tissues of castor
bean seedlings were followed during germination and early growth. For measurement, lectins …

Four isozymes of β-N-acetylhexosaminidase (β-NAHA) from pea seeds (Pisum sativum L.)
have been separated, with one, designated β-NAHA-II, purified to apparent homogeneity by …

Ricinus communis agglutinin (RCA) B chain, in contrast to ricin B chain, contains fucose.
Since both RCA and ricin B chain lose two oligosaccharide side chains when treated with β-…

Clathrin-coated vesicles have been isolated from cotyledons of both developing and
germinating pea seeds using differential centrifugation, ribonuclease treatment, discontinuous …

A comparative study has been made of clathrin-coated vesicles from developing pea (Pisum
sativum L.) cotyledons and bovine brains in order to characterize the clathrin light chains …

The red, purple, and blue colours found in many plants are due to two classes of water soluble
pig ments, anthocyanins and betacyanins. The antho cyanins are flavonoids, a class of …
