Comparative Water Relations of Phaseolus vulgaris L. and Phaseolus acutifolius Gray

Comparative Water Relations of Phaseolus vulgaris L. and Phaseolus acutifolius Gray.

Leaf area expansion, dry weight, and water relations of Phaseolus vulgaris L. and P. acutifolius Gray were compared during a drying cycle in the greenhouse to understand the characteristics which contribute to the superior drought tolerance of P. acutifolius. Stomates of P. acutifolius closed at a much higher water potential than those of P. vulgaris, delaying dehydration of leaf tissue. P. acu...

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 ...

WATER ABSORPTION IN BEAN SEEDS (Phaseolus vulgaris L.) DURING PROCESSING

The purpose of this paper was to estimate and to evaluate the hydration curves of three kinds of dry bean varieties (Phaseolus vulgaris L.), besides adjusting the Peleg’s model to the experimental values under several soaking temperatures. Bean seeds of pinto, black and red kidney varieties were soaked in distilled water in the temperatures of 20, 30, 40 and 50 °C. The constant C1 (Peleg rate c...

List of Genes - Phaseolus vulgaris L

The arcelin-5 gene of Phaseolus vulgaris directs high seed-specific expression in transgenic Phaseolus acutifolius and Arabidopsis plants.

The regulatory sequences of many genes encoding seed storage proteins have been used to drive seed-specific expression of a variety of proteins in transgenic plants. Because the levels at which these transgene-derived proteins accumulate are generally quite low, we investigated the utility of the arcelin-5 regulatory sequences in obtaining high seed-specific expression in transgenic plants. Arc...
