Chromosomes in Maize and Maize Relatives »
An understanding of the laws of heredity is essential if improvement of plant breeding is to be controlled intelligently. A comprehensive understanding of the mechanism of inheritance demands definite knowledge of the chromosome number, not only of the forms it is desirous to improve but also of the related species. The present paper presents the results of a study of the chromosome number in s...
متن کاملGene flow between crops and their wild relatives
Gene flow from domesticated plants to free-growing relatives was a rather trivial issue before the advent of transgenic crops. Gene flow into crops was relatively more important, especially to plant breeders trying to introduce new genes in a crop, or to breeders and seed growers wanting to ensure the genetic purity of a cultivar. Genes can now be transferred from bacteria, or potentially any p...
متن کاملMonitoring gene flow between wild relatives and landraces of common bean in Costa Rica
Introduction Gene flow is the spread of genetic material among populations and may constitute an important evolutionary force to create genetic variability. We study possible cases of gene flow in accessions of Phaseolus vulgaris L. collected in the Central Valley of Costa Rica (Araya et al. 2001), The present study aims to establish the movement of genes in the complex wild/weed/cultivated of ...
متن کاملComparative Analysis of Genome-Wide Chromosomal Histone Modification Patterns in Maize Cultivars and Their Wild Relatives
Recent advances demonstrate that epigenome changes can also cause phenotypic diversity and can be heritable across generations, indicating that they may play an important role in evolutionary processes. In this study, we analyzed the chromosomal distribution of several histone modifications in five elite maize cultivars (B73, Mo17, Chang7-2, Zheng58, ZD958) and their two wild relatives (Zea may...
متن کاملBacterial endophytes from wild maize suppress Fusarium graminearum in modern maize and inhibit mycotoxin accumulation
Wild maize (teosinte) has been reported to be less susceptible to pests than their modern maize (corn) relatives. Endophytes, defined as microbes that inhabit plants without causing disease, are known for their ability to antagonize plant pests and pathogens. We hypothesized that the wild relatives of modern maize may host endophytes that combat pathogens. Fusarium graminearum is the fungus tha...
