Microcallus growth from maize protoplasts (1987)
Imbrie-Milligan, C. W., Kamo, K. K., Hodges, T. K.
Maize ( Zea mays L. ) protoplasts obtained from Type I and Type II calli from several genotypes were shown to be capable of synthesizing cell walls and forming small clusters of cells. The medium...
Microcallus formation from maize protoplasts prepared from embryogenic callus (1986)
Imbrie-Milligan, C. W., Hodges, T. K.
Conditions have been developed that induce maize ( Zea mays L.) protoplasts to re-synthesize cell walls and to initiate cell divisions. Two types of embryogenic maize callus were used as a source of...
FLP-mediated recombination of FRT sites in the maize genome.
Lyznik, L A, Rao, K V, Hodges, T K
Molecular evidence is provided for genomic recombinations in maize cells induced by the yeast FLP/FRT site-specific recombination system. The FLP protein recombined FRT sites previously integrated...
Nucleotide sequence of a rice genomic pyruvate decarboxylase gene that lacks introns: a pseudo-gene?
Hossain, M A, McGee, J D, Grover, A, Dennis, E S, Peacock, W J, Hodges, T K, ...
Activity of yeast FLP recombinase in maize and rice protoplasts.
Lyznik, L A, Mitchell, J C, Hirayama, L, Hodges, T K
We have demonstrated that a yeast FLP/FRT site-specific recombination system functions in maize and rice protoplasts. FLP recombinase activity was monitored by reactivation of beta-glucuronidase...
Membrane-bound Adenosine Triphosphatase Activities of Oat Roots 1
Leonard, R. T., Hansen, D., Hodges, T. K.
Homogenates of oat (Avena sativa cv. Goodfield) roots contained at least five membrane-associated adenosine triphosphatase (ATPase) activities. The membrane-bound ATPases were separated on sucrose...
Characterization of Plasma Membrane-associated Adenosine Triphosphase Activity of Oat Roots 1
ATPase activity of plasma membranes isolated from oat (Avena sativa L. cv. Goodfield) roots was activated by divalent cations (Mg2+ = Mn2+ > Zn2+ > Fe2+ > Ca2+) and further stimulated by KCl and a...
Hodges, T. K., Leonard, R. T., Bracker, C. E., Keenan, T. W.
A membrane-bound adenosine triphosphatase (EC 3.6.1.3) that requires Mg++ and that is stimulated by monovalent ions has been purified 7- to 8-fold from homogenates of oat (Avena sativa L. Cult....
Monovalent Ion Stimulated Adenosine Triphosphatase From Oat Roots 1
Monovalent ion stimulated ATPase activity from oat (Avena sativa) roots has been found to be associated with various membrane fractions (cell wall, mitochondrial and microsomal) of oat roots. The...
Correlation between Ion Fluxes and Ion-stimulated Adenosine Triphosphatase Activity of Plant Roots 1
Fisher, J. D., Hansen, Dale, Hodges, T. K.
The energy-dependent influx of Rb+ into excised roots of corn, wheat, and barley has been determined and compared to the Rb+-stimulated ATPase activity of membrane fractions obtained from root...
Phosphorus Metabolism of Germinating Oat Seeds 1
An investigation has been made of the changes in the major phosphorus containing substances in Avena sativa during the first 8 days of dark germination. The endosperm, roots, and shoots were analyzed...
Calcium Inhibition of Potassium Absorption in Corn Roots 1
Calcium (or magnesium) sulfate or chloride was found to inhibit energy dependent potassium transport in excised corn roots. This Ca2+ inhibition of K+ transport was most pronounced during the initial...
Characterization of Energy-Dependent Ca2+ Transport in Maize Mitochondria 1
Experimental conditions which optimize both substrate- and ATP-dependent Ca2+ transport in corn (Zea mays) mitochondria have been determined. It has been found that a substrate (pyruvate + succinate)...
