Inheritance of Height in Peas

Like peas in a pod

In January, Harold Varmus will begin the next stage in an unusual career. He’s gone from English literature to medicine to bench science to Washington science bureaucrat, and now he becomes the well-paid (some would say extremely well-paid) president of a private, not-for-profit treatment and research facility, the Memorial Sloan Kettering Cancer Center in New York. He’s succeeded in everything...

Peas and Primroses

Remember the monk and the peas? The story introduced school children to genetics long before the human genome made the evening news. The Augustinian monk Gregor Mendel conducted hundreds of experiments on the edible pea, crossing peas that were smooth or wrinkled, peas that grew tall or short, peas that had white or violet flowers. He found that the results of these crosses were predictable, an...

Subcellular Localization of IAA Oxidase in Peas.

Indoleacetic acid (IAA) oxidase has been reported to be involved in plant growth because of its alleged role in the control of endogenous IAA levels. This purported role was reevaluated in terms of the properties and subcellular location of the enzyme in etiolated pea (Pisum sativum L. var. Alaska) epicotyls.The enzymic properties of IAA oxidase in the floating pea epicotyl segments are similar...

3-Methyleneoxindole reductase of peas.

A 100-fold purification of a reduced triphosphopyridine nucleotide/3-methyleneoxindole reductase of peas has been achieved using conventional protein fractionation procedures. Reduced diphosphopyridine nucleotide is 25-fold less effective than reduced triphosphopyridine nucleotide as the reductant. The preparation is free of other reductase activities including those linking the oxidation of re...
