region of the genes, denominated HAIR (HspR associated inverted repeat). For these studies we will construct a null mutant in gen CC0081, whose phenotype will be analyzed with respect to different kinds of environmental stresses. Another objective of this project deals with the characterization of 5 ECF (extracytoplasmic function) sigma factors from Caulobacter: SigF, SigU, SigT, SigE and SigR....

By characterizing the struggle to measure variation as a struggle between two opposing views, the classical and balance theories of population genetics, I have in part obscured the underlying problem of making a functional whole out of theory and observation. Suppose that the experiments of Wallace and of Mukai had proved beyond any reasonable doubt that new mutations were, on the average, hete...

E in maize has been undertaken. This study has provided a unique opportunity to examine the muI t tation process at a number of different loci in the chromosomes. For some of these loci, several independent inceptions of instability have 1 occurred during the progress of this study. The types of mutation that appear, and the types of instability expression, need not be the same at any one locus...

Microsatellites, also known as simple sequence repeats, are short (1-6 bp long) repetitive DNA sequences present in chloroplast genomes (cpDNAs). In this work, chloroplast genomes of eight species (Glycine canescens, G. cyrtoloba, G. dolichocarpa, G. falcata, G. max, G. soja, G. stenophita, and G. tomentella) from Glycine genus were screened for cpSSRs by utilisation of MISA perl script with a ...

The Human Genome Project is providing a wealth of information about the human gene repertoire , and promises to furnish a complete genome sequence (and thereby a complete gene catalog) by the year 2005. This enormous output of data is beginning to be complemented by large scale studies designed to uncover normally occurring variations within human gene sequences. Much of this variability is ver...
