Increased Root Initiation in Pinto Bean Hypocotyls With 2,4-Dinitrophenol

Pinto bean consumption reduces biomarkers for heart disease risk.

OBJECTIVE To determine effects of daily intake of 1/2 cup pinto beans, black-eyed peas or carrots (placebo) on risk factors for coronary heart disease (CHD) and diabetes mellitus (DM) in free-living, mildly insulin resistant adults over an 8 week period. METHODS Randomized, crossover 3x3 block design. Sixteen participants (7 men, 9 women) received each treatment for eight-weeks with two-week ...

Increased soil P availability induced by faba bean root exudation stimulates root 1 growth and P uptake in neighbouring maize

Backcross breeding for improved resistance to common bacterial blight in pinto bean (Phaseolus vulgaris

Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli reduces common bean (Phaseolus vulgaris L.) yield and quality worldwide. Genetic resistance provides effective disease control; however, a high level of resistance is difficult to attain and does not exist in pinto bean, the most important dry bean market class in North America. Our objective was to determine if a backc...

Mechanism of the Decline in Vacuolar H -ATPase Activity in Mung Bean Hypocotyls during Chilling.

The mechanism responsible for the decrease in the activity of vacuolar H(+) -ATPase during chilling was investigated in seedlings of mung bean (Vigna radiata). After chilling at 0 degrees C for 3 d, the activity of vacuolar H(+) -ATPase, calculated on the basis of membrane protein, decreased to 47% of the original value. Of the nine subunits of the ATPase, the specific contents of at least six ...

Effect of gibberellic Acid on crown gall tumor induction in aging primary pinto bean leaves.

Gibberellic acid was tested for its effect on tumor induction by Agrobacterium tumefaciens in primary pinto bean (Phaseolus vulgaris) leaves in various stages of development. The hormone was found to promote tumor induction in partially aged leaves but did not effect tumor induction in very young leaves or in fully matured leaves. It is suggested that the natural loss of susceptibility to tumor...
