... From 55,923 successful step B matings, we recovered only 463 lethals (0.84%)in a region (6D17D1) that represents, based on polytene chromosome bands, approximately 5% of the X chromosome. This figure suggests an X-linked lethal frequency of only O.lB/chromosome. The low yield almost certainly reflec ...

Molecular marker-assisted selection for resistance to pathogens in tomato

... Since 1980s molecular markers are being widely used as a principal tool for the breeding of many crops, among these tomato. In particular, a great work has been realized to find molecular markers linked to disease resistance genes. Up till now, more than 40 genes (including many single genes and qua ...

Of course, this method cannot normally be used to predict every exon, as it is difficult to achieve 100% coverage for every protein by mass spectrometry at the low levels usually available in biological experiments.

Minimal genome

The concept of minimal genome assumes that genomes can be reduced to a bare minimum, given that they contain many non-essential genes of limited or situational importance to the organism. Therefore, if a collection of all the essential genes were put together, a minimum genome could be created artificially in a stable environment. By adding more genes, the creation of an organism of desired properties is possible. The concept of minimal genome arose from the observations that many genes do not appear to be necessary for survival. In order to create a new organism a scientist must determine the minimal set of genes required for metabolism and replication. This can be achieved by experimental and computational analysis of the biochemical pathways needed to carry out basic metabolism and reproduction. A good model for a minimal genome is Mycoplasma genitalium, the organism with the smallest known genome. Most genes that are used by this organism are usually considered essential for survival; based on this concept a minimal set of 256 genes has been proposed.
