P-NMR Spectroscopy of Roots of Intact Corn Seedlings.
The application of (31)P nuclear magnetic resonance spectroscopy to the study of metabolism in roots of intact corn seedlings is described. (31)P-NMR spectra of developmentally distinct parts of primary roots of whole seedlings are presented. The spectra are of quality comparable to those of excised pieces of plant tissue.
متن کاملStudies on the b-Type Cytochromes from Mung Bean Seedlings
In the previous papers of this series (1, 2), some of the properties of purified mung bean cytochrome b-555 have been described. The present investigation was undertaken to gain some information on the chemical structure of this hemoprotein. The size, amino acid composition, and terminal amino acids of cytochrome b-555 have been examined; the nature of the binding between heme and protein has a...
متن کاملDetailed quantitative analysis of architectural traits of basal roots of young seedlings of bean in response to auxin and ethylene.
Vertical placement of roots within the soil determines their efficiency of acquisition of heterogeneous belowground resources. This study quantifies the architectural traits of seedling basal roots of bean (Phaseolus vulgaris), and shows that the distribution of root tips at different depths results from a combined effect of both basal root growth angle (BRGA) and root length. Based on emergenc...
متن کاملReversibility of chilling injury to corn seedlings.
Seedlings of corn (Zea mays) were tested for recovery from chilling injury incurred at 0.3 +/- 0.3 C. At 0.3 C visual leaf injury appeared in 36 hours, whereas stem and root injuries appeared later. Appearance of leaf injury was preceded by a rise in O(2) uptake and a lessened effect of 2,4-dinitrophenol on O(2) uptake by leaf segments and was accompanied by increased ion leakage from the leave...
متن کاملRole of carotenoids in the phototropic response of corn seedlings.
The herbicide, 4 chloro-5-(methylamino)-2-(alpha,alpha,alpha,-trifluoro-m-tolyl)-3 (2H)-pyridazinone (SAN 9789), which blocks the synthesis in higher plants of colored carotenoids but not of flavins, was used to examine the involvement of carotenoids in corn seedling phototropism. It was concluded that "bulk" carotenoids are not the photoreceptor pigment based on the results that increasing con...
