The largest eukaryotic genome of them all?
We report the largest eukaryotic genome to date in the monocot Paris japonica (Melanthiaceae, 1C = 152.23 pg), measured using flow cytometry. This value is 15% larger than any previous estimate and extends the range of genome sizes to c. 2400-fold across angiosperms and c. 66 000-fold across eukaryotes. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 164, 1...
متن کاملEvolution of the Largest Mammalian Genome
The genome of the red vizcacha rat (Rodentia, Octodontidae, Tympanoctomys barrerae) is the largest of all mammals, and about double the size of their close relative, the mountain vizcacha rat Octomys mimax, even though the lineages that gave rise to these species diverged from each other only about 5 Ma. The mechanism for this rapid genome expansion is controversial, and hypothesized to be a co...
متن کاملBringing them all Together
A sequent calculus for hybrid logics is developed from a calculus for classical predicat logic by a series of transformations. We formalize the semantic theory of hybrid logic using a sequent calculus for predicate logic plus axioms. This works, but it is ugly. The unnattractive features are removed one-by-one, until the final vestiges of the metalanguage can be set aside to reveal a fully inte...
متن کاملCo-Büching Them All
We solve the open problems of translating, when possible, all common classes of nondeterministic word automata to deterministic and nondeterministic co-Büchi word automata. The handled classes include Büchi, parity, Rabin, Streett and Muller automata. The translations follow a unified approach and are all asymptotically tight. The problem of translating Büchi automata to equivalent co-Büchi aut...
متن کاملNidovirales: evolving the largest RNA virus genome.
This review focuses on the monophyletic group of animal RNA viruses united in the order Nidovirales. The order includes the distantly related coronaviruses, toroviruses, and roniviruses, which possess the largest known RNA genomes (from 26 to 32kb) and will therefore be called "large" nidoviruses in this review. They are compared with their arterivirus cousins, which also belong to the Nidovira...
