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...

Transcriptional Analysis of Drought-Induced Genes in the Roots of a Tolerant Genotype of the Common Bean (Phaseolus vulgaris L.)

In Brazil, common bean (Phaseolus vulgaris L.) productivity is severely affected by drought stress due to low technology cultivation systems. Our purpose was to identify differentially expressed genes in roots of a genotype tolerant to water deficit (BAT 477) when submitted to an interruption of irrigation during its development. A SSH library was constructed taking as "driver" the genotype Car...

Abscisic Acid Accumulation in Developing Seeds of Phaseolus vulgaris L.

Free and bound abscisic acid (ABA) in the pod, seed coat, and embryo were determined separately throughout seed development of Phaseolus vulgaris L. cv. ;Taylor's Horticultural.' An internal standard method of gas-liquid chromatography was used for ABA quantification. In the embryo, two peaks of free ABA occurred at days 22 (1.18 micrograms per gram or 5.5 micromolar) and 28 (1.74 micrograms pe...
