Studies of l-Cysteine Biosynthetic Enzymes in Phaseolus vulgaris L.

In higher plants the biosynthesis of l-cysteine from l-serine, acetylCoA, and sulfide requires serine transacetylase and O-acetylserine sulfhydrylase. The distribution of these enzymes in kidney bean (Phaseolus vulgaris L. cv. Red Kidney) seedlings was determined. Between one-third and two-thirds of the serine transacetylase activity was associated with mitochondria, whereas all of the O-acetyl...

On the Origin of the Common Bean (Phaseolus vulgaris L.)

Phylogeographic methods provide the tools to accurately access the geographic origin and diversification of crop species. In the present commentary, I urge the common bean community to face those methods and a tree-thinking mentality with regards to the long standing debate of the origin of common bean. Such efforts will ultimately bring back interest into wild bean studies and reinforce the un...

Temperature Effects on Mitochondrial Respiration in Phaseolus acutifolius A. Gray and Phaseolus vulgaris L.

Electron transport, using succinate as a substrate, was measured polarographically in mitochondria isolated from Phaseolus vulgaris and P. acutifolius plants at 25 degrees C and 32 degrees C. Mitochondria isolated from P. vulgaris plants grown at 32 degrees C had reduced electron transport and were substantially uncoupled. Growth at 32 degrees C had no effect on electron transport or oxidative ...
