Vascularization of the Node in Zea Mays
Botanical Gazette, 19281. The vascular strands in Zea mays can readily be stained for study with methylene blue, as shown in fig. 1. 2. The stained bundles and the complex nodal structure can readily be freed from confusing parenchymatous tissues by retting. 3. Single vascular bundles seldom pass through more than two or three nodes without branching. 4. The nodal complex of

The removal and culture of embryos of higher plants was one of the earliest successful techniques in plant tissue and organ culture. P. R. White desribed a simple technique in his book on tissue culture in which embryos removed from the seeds of Shepherd’s Purse (Capsella bursa-pastoris) can be cultured under completely aseptic conditions.

Immunochemical prognosis of heterosis in Zea mays
Theoretical and Applied Genetics, 1974Heterosis is a complex biological phenomenon. Because of the complex interaction and interrelation between "genes - metabolism - environment", it is hardly possible to expect a clarification of the heterosis phenomenon through simple genetic explanations only (Hagemann et al. 1967).We have followed an immunochemical aspect and method of research.

Maize is one of the most important cereal crops to be extensively characterized cytologically. McClintock (1929) gave the first indication of heterochromatinous knobs within pachytene maize chromosomes. Proceeding from chromosome morphology and data on the location of knobs, she provided early identification of all maize chromosomes.

Phytochemistry, 1973
Abstract A number of adenine derivatives with cytokinin activity were isolated from immature sweet corn (Zea mays) kernels. The following structures were assigned: 9-β- d -ribofuranosylzeatin, 9-β- d -ribofuranosylzeatin 5′-monophosphate, 6-(1-carboxy-2-hydroxypropylamino)-9-ribofuranosylpurine, 6-(2,3,4-trihydroxy-3-methylbutylamino)purine, 2 ...

Maize (Zea mays L.) is the third most important food crop globally after wheat and rice. In sub-Saharan Africa, tropical maize has traditionally been the main staple of the diet; 95 % of the maize grown is consumed directly as human food and as an important source of income for the resource-poor rural population.

Asparagine Synthetase in Zea mays
1979In legume cotyledons, asparagine is synthesized by a transfer of the amide nitrogen of glutamine to aspartate. The asparagine synthetase reaction requires ATP-Mg²⁺, aspartate and glutamine as substrates, although NH₄Cl can act as a rather inefficient nitrogen donor.
