A procedure is described that permits the use of radiotracer methods for examining crown gall tumors in the presence of the initiating agent Agrobacterium tumefaciens. On the basis of sensitivity testing using the disc diffusion technique and the minimum inhibitory concentration procedure and incorporation of radioactive phosphorus into nucleic acids, it was determined that A. tumefaciens was m...

BACKGROUND An in vitro digestion and Caco-2 cell model may predict iron bioavailability to humans; however, direct comparisons are lacking. OBJECTIVE The objective was to test the differences in iron bioavailability between 2 maize varieties and 2 bean varieties (white beans and colored beans) by comparing human, Caco-2, and algorithm results. DESIGN Two randomized, 2 x 2 factorial experime...

The present study aimed to characterize pinto and cranberry bean landraces of Kashmir valley. A set 30 genotypes including 16 12 type two checks viz., Shalimar Rajmash-1 (SR-1) French Bean-1 (SFB-1) were evaluated for seven qualitative 10 quantitative traits.  There was a substantial variation among accessions (28 2 checks) all the Out 28 landrace accessions, 13 bushy 15 pole type.  P...

Acid-soluble nucleotides of unifoliate leaves of Pinto bean plants (Phaseolus vulgaris L.) were determined at young, mature, and senescent stages of development. At least 25 components could be distinguished on the basis of inorganic phosphorus determinations and 37 or more fractions on the basis of (32)P labeling, with adenosine di- and triphosphates accounting for 60% of the total moles of nu...

The relative number of copies of pumpkin DNA sequences which are complementary to high molecular weight ribosomal RNA (HMW rRNA), 5S and 4S RNA was found, by DNA-RNA hybridization experiments, to be approximately 1:1.2:2.5. At saturation, the levels of hybridization obtained with these RNAs were 2.4%, 0.029% and 0.044%, respectively. Based upon a haploid genomic DNA content of 4.9 x 10^' dalton...
