Tissue Culture Regeneration of Plants in Zea diploperennis, a Close Relative of Corn
Nature Biotechnology, 1984High frequency and reliable plant regeneration from somatic cells of Zea mays is the key step in allowing the tools of soma-clonal variation, somatic cell hybridization, and recombinant DNA to be used in the development of improved breeding lines. This communication describes high frequency plant regeneration from somatic stem donor tissue of field ...

Phytin element composition and phytate distribution and content were determined in endosperm, scutellum, radicle and plumule of mature Zea diploperennis and Zea mays grains. The embryo of Z. diploperennis and Z. mays contained 90% and 86% of total grain phytate, respectively, with most of the phytate localized in the scutellum and radicle. All examined

Theoretical and Applied Genetics, 1987
The coding and flanking sequences of the 18S-5S ribosomal RNA genes and the cytochrome oxidase subunit II gene of Zea diploperennis mitochondrial DNA have been determined and compared to the corresponding sequences of normal maize (Zea mays L.) Both length and substitution mutations are found in the coding region of the 18S rRNA gene, whereas only one ...

Plant Breeding, 2019 Abstract Striga hermonthica can cause as high as 100% yield loss in maize depending on soil fertility level, type of genotype, severity of infestation and climatic conditions. Understanding the mode of inheritance of Striga resistance in maize is crucial for introgression of resistance genes into tropical germplasm and deployment of resistant varieties.

Zea diploperennis (Gramineae): A New Teosinte from Mexico
Science, 1979A perennial teosinte or "wild maize" endemic to the Cerro de San Miguel, Sierra de Manantlan, Jalisco, Mexico differs from Zea perennis by dimorphic rhizomes, robust habit, and a larger number of longer, laxer tassel branches.

Analysis of the Lectins from Teosinte (Zea diploperennis) and Maize (Zea mays) Coleoptiles
Journal of Agricultural and Food Chemistry, 2003To identify molecular evidence of the common origin of maize and teosinte, a lectin from teosinte coleoptile (TCL) was purified, through affinity chromatography on a lactosyl-Sepharose column, and some of the physicochemical parameters were compared with those from the maize coleoptile lectin (CCL).

Somatic embryogenesis and plant regeneration in two-year old cultures of Zea diploperennis
Plant Cell Reports, 1988Immature embryos and immature leaf tissues were used to establish embryogenic cultures of Zea diploperennis. Callus was induced on media containing MS salts and vitamins, sucrose (2% for leaves, 6% for embryos), 5% coconut milk and 1-6 mg/l 2, 4-D. Embryogenic callus was maintained by subculturing on media containing MS salts and vitamins, 2% sucrose ...

Chilling Stress and Active-Oxygen Enzymes in Zea mays and Zea diploperennis
1990Photosynthesis is one of the first processes affected when chilling-sensitive plants are exposed to chilling temperatures (1,2). The symptoms of chilling damage are particularly pronounced in the presence of light and dioxygen. Many workers have shown that decreasing oxygen partial pressures from air levels produces a significant decrease in the ...
