Maize (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...
متن کاملEpistasis in Maize (zea Mays
ISHER (1918) provided a framework for the characterization of genotypic variance whereby he partitioned it into three components: ( 1 ) a portion associated with the average effects of genes, (2) a portion associated with dominance effects (allelic interactions) of genes, and (3) a portion associated with epistatic effects (nonallelic interactions) of genes. A logical method for the further sub...
متن کاملLateral ABA transport in maize roots (Zea mays): visualization by immunolocalization.
The intensity of an ABA (abscisic acid) signal as a root-to-shoot signal, as well as its action on root hydraulic conductivity, strongly depends on the distribution of ABA during its radial transport across roots. Therefore ABA was visualized by immunolocalization with monoclonal ABA antibodies under conditions of lateral water flow induced by the application of a pressure gradient to the cut s...
متن کاملEarly colonization pattern of maize (Zea mays L. Poales, Poaceae) roots by Herbaspirillum seropedicae (Burkholderiales, Oxalobacteraceae)
The bacterium Herbaspirillum seropedicae is an endophytic diazotroph found in several plants, including economically important poaceous species. However, the mechanisms involved in the interaction between H. seropedicae and these plants are not completely characterized. We investigated the attachment of Herbaspirillum to maize roots and the invasion of the roots by this bacterium using H. serop...
متن کاملUptake of Strontium by Roots of Zea Mays.
The uptake of Sr by sectionls of tlle plrinlary roots of mlaize seedlings close to the mleristemii parallels that of Na, Ca, and Cl ( 3, 4). Like these ions Sr is taken up independentlIof metabolism by the nonvacuolated tissue conmprising the first 1.8 mm1Ill of the root tip. Vacuolated tissule farther froml the maeristeml absorbs Sr in large amiiounts by a process that requires aerobic metabol...
