Uneven chromosome contraction and expansion in the maize genome

Uneven chromosome contraction and expansion in the maize genome.

Maize (Zea mays or corn), both a major food source and an important cytogenetic model, evolved from a tetraploid that arose about 4.8 million years ago (Mya). As a result, maize has extensive duplicated regions within its genome. We have sequenced the two copies of one such region, generating 7.8 Mb of sequence spanning 17.4 cM of the short arm of chromosome 1 and 6.6 Mb (25.6 cM) from the long...

The Measurement Object Expansion and Contraction Problem

Over the last decade, industrial metrology has experienced a tremendous improvement in measurement sensors. First, optical tooling was made obsolete by theodolite systems, which in turn are now being displaced by laser trackers. Furthermore, there are already first indications that laser trackers, as far as static measurements are concerned, will have to compete very hard with the next generati...
