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 کاملUncultured bacterial diversity in tropical maize (Zea mays L.) rhizosphere.
Structure of maize (Zea mays L.) rhizosphere bacteria was evaluated to explore the feasibility of identifying novel rhizosphere bacteria using culture-independent method based on direct amplification and analysis of 16S rRNA gene (rRNA) sequences and especially to obtain a better understanding of bacterial community structure and diversity from maize. A total of 274 sequences were analyzed and ...
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...
متن کاملPatterns of diversity and recombination along chromosome 1 of maize (Zea mays ssp. mays L.).
We investigate the interplay between genetic diversity and recombination in maize (Zea mays ssp. mays). Genetic diversity was measured in three types of markers: single-nucleotide polymorphisms, indels, and microsatellites. All three were examined in a sample of previously published DNA sequences from 21 loci on maize chromosome 1. Small indels (1-5 bp) were numerous and far more common than la...
متن کاملB chromosomes in popcorn (Zea mays L.).
Cytological analysis of microsporogenesis in 72 popcorn plants, comprising nine from the original population (CMS-43, S(0)) and 63 from seven cycles of self-fertilization (S(1) to S(7)), one plant of S(0) generation (plant 2) was identified with B chromosomes. The number of B chromosomes varied from two to three in the same anther. The pattern of chromosome pairing and meiotic behavior of Bs we...
