Poinsettia Cultivars Differ in Their Response to Molybdenum Deficiency

Purine catabolism in molybdenum deficiency.

A low protein diet (1, 2) removed about three-fourths of the xanthine oxidase from the entire rat (3), while a purified diet containing tungstate reduced the tissue xanthine oxidase to a level at which it could not, be detected manometrically (4) ; neither of these dietary procedures had any effect on the uric acid or allantoin excretion by this species. Chicks fed a tungstate-containing diet e...

Variation in the response of barley cultivars to nirrogen fertilizer

Comparing nitrate storage and remobilization in two rice cultivars that differ in their nitrogen use efficiency.

Soil nitrogen (N) is available to rice crops as either nitrate or ammonium, but only nitrate can be accrued in cells and so factors that influence its storage and remobilization are important for N use efficiency (NUE). The hypothesis that the ability of rice crops to remobilize N storage pools is an indicator of NUE was tested. When two commonly grown Chinese rice cultivars, Nong Ken (NK) and ...

Child Neurology: Molybdenum cofactor deficiency.

Molybdenum cofactor deficiency (MoCD) is a rare inherited metabolic disorder characterized by neonatal onset intractable seizures, severe psychomotor retardation, dysmorphic facies, and dislocated ocular lenses. A characteristic biochemical profile permits early diagnosis. Although more than 100 genetically characterized patients have been reported, this number is discrepant with the actual pre...

Effect of Pseudomonas putida on Growth and Anthocyanin Pigment in Two Poinsettia (Euphorbia pulcherrima) Cultivars

Pseudomonas putida is plant growth promoting rhizobacteria (PGPR) that have the capacity to improve growth in plants. The purpose of this study was to determine growth and anthocyanin pigmentation of the bracts in two poinsettia Euphorbia pulcherrima cultivars (Prestige and Sonora Marble) using three strains of P. putida, as well as a mixture of the three (MIX). Comparison with the control grou...
