Toxicity and Translocation of Selenium in Phaseolus vulgaris L.

Influence of Translocation of Photosynthetic Efficiency of Phaseolus vulgaris L.

Measurements of net photosynthesis show that in Phaseolus vulgaris L. the cultivar Michelite-62 exceeds the cultivar Red Kidney in net CO(2) uptake by 23 to 31%. Data on translocation of pulse label indicate that export of a pulse of photosynthetically assimilated (14)C from the source leaf of either M-62 or Red Kidney follows an exponential pattern and shows an initial rapid phase followed by ...

Ethylene Biosynthesis and Cadmium Toxicity in Leaf Tissue of Beans (Phaseolus vulgaris L.).

Stress ethylene production in bean (Phaseolus vulgaris L., cv. Taylor's Horticultural) leaf tissue was stimulated by Cd(2+) at concentrations above 1 micromolar. Cd(2+)-induced ethylene biosynthesis was dependent upon synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) by ACC synthase. Activity of ACC synthase and ethylene production rate peaked at 8 h of treatment. The subsequent decline ...

List of Genes - Phaseolus vulgaris L

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...

Toxicity of Heavy Metals and Their Molecular Detection on Phaseolus vulgaris (L.)

Phaseolus vulgaris represents a great source of nutrit io n fo r millions of people, and is the second most important legume crop, after soybean. Assessment of environmental contamination on e cology (plant) at molecular and population levels is important in risk quantification and remediation s tud y . Heavy metal toxicity in plants is to induce o xidative s tress linked to oxidation of protei...
