Structure of the Threonine-Rich Extensin from Zea mays.
Chymotryptic digestion of a threonine-rich hydroxyproline-rich glycoprotein (THRGP) purified from the cell surface of a Zea mays cell suspension culture gave a peptide map dominated by the hexadecapeptide TC5: Thr-Hyp-Ser-Hyp-Lys-Pro-Hyp-Thr-Pro-Lys-Pro-Thr-Hyp-Hyp-Thr-Tyr, in which the repetitive motif Ser-Hyp-Lys-Pro-Hyp-Thr-Pro-Lys is homologous with the dominant decamer of P1-type dicot ext...
متن کاملStructure of the novel monomeric glyoxalase I from Zea mays.
The glyoxalase system is ubiquitous among all forms of life owing to its central role in relieving the cell from the accumulation of methylglyoxal, a toxic metabolic byproduct. In higher plants, this system is upregulated under diverse metabolic stress conditions, such as in the defence response to infection by pathogenic microorganisms. Despite their proven fundamental role in metabolic stress...
متن کاملCloning and expression analysis of hemoglobin genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis).
With the exception of barley and rice, little is known about the existence of hemoglobins (Hbs) in cereals. This work reports the cloning and analysis of hb genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis). Coding sequences of maize and teosinte hb genes (hbm and hbt, respectively) are highly similar to each other and are interrupted by three introns located at ide...
متن کاملRecombination in Zea Mays
meiotic process in plants or animals does not necessarily produce the same T:!rcentage of recombinants in male and female germ cells. In maize, the frequency of recombination in a particular chromosomal region is usually higher in microsporogenesis than in megasporogenesis, if a difference exists at all. Chromosomes 2 and 10, according to genetic tests thus far, have similar recombination frequ...
متن کاملMaize (Zea mays L.).
Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...
