Genetic and Genomic Toolbox of Zea mays
Maize has a long history of genetic and genomic tool development and is considered one of the most accessible higher plant systems. With a fully sequenced genome, a suite of cytogenetic tools, methods for both forward and reverse genetics, and characterized phenotype markers, maize is amenable to studying questions beyond plant biology. Major discoveries in the areas of transposons, imprinting,...
متن کاملPathways of genetic transfer from Tripsacum to Zea mays.
The cytogenetic interactions in maize x Tripsacum hybrid derivatives can be remarkably complex. The number of viable, somewhat female fertile chromosome combinations is astonishing. Fifty-four different combinations are listed in this paper, and others are certainly possible. In successive backcrosses to maize, chromosome numbers scale both up and down with ease, sometimes stabilizing for a few...
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...
متن کاملGenetic Diversity in Maize (Zea mays L.) Inbred Lines
Thirty yellow inbred lines of normal maize were evaluated for thirteen parameters at the experimental field of Hajee Mohammad Danesh Science and Technology University during 2010-11 to study the genetic divergence using multivariate analysis. The thirty inbreds fell into six distinct clusters. The intra-cluster distances in all the six clusters were more or less low, indicating that the genotyp...
