The genealogy of genealogy of neurons
Two scenarios of neuronal evolution (monophyly and polyphyly) are discussed in the historical timeline starting from the 19th century. The recent genomic studies on Ctenophores re-initiated a broad interest in the hypotheses of independent origins of neurons. However, even earlier work on ctenophores suggested that their nervous systems are unique in many aspects of their organization and a pos...
متن کاملGenealogy of the "Green Revolution" gene in rice.
During the "Green Revolution" of rice, high-yielding varieties (HYVs) were developed using a semi-dwarf gene (sd1 or OsGA20ox2). The presence or absence of the two mutant alleles (DGWG type in Dee-geo-woo-gen and JKK type in Jikkoku) were surveyed by PCR using 256 accessions of eight wild and two cultivate rice species. The DGWG allele was detected in a landrace (Oryza sativa) and two accession...
متن کاملGene genealogy in three related populations: consistency probability between gene and population trees.
A genealogical relationship among genes at a locus (gene tree) sampled from three related populations was examined with special reference to population relatedness (population tree). A phylogenetically informative event in a gene tree constructed from nucleotide differences consists of interspecific coalescences of genes in each of which two genes sampled from different populations are descende...
متن کاملA giant graviton genealogy
In this article we extend the construction of giant gravitons from holomorphic surfaces [1] to the ABJM correspondence. We construct a new class of 1 6 -BPS M5-branes wrapping 5-manifolds in S/Zk and supported by a large angular momentum in the orbifold space. These orbifold giant gravitons undergo a supersymmetry enhancement to 1 3 -BPS and 1 2 -BPS configurations in special cases. The compact...
متن کاملGenealogy of Illustrated Manuscripts
1. Introduction. Illustrated manuscripts may be analysed in terms of both their texts and their illustrations. While statistical techniques have long been applied to the textual analysis of manuscripts, e.g., Lebart and Salem (1994), no corresponding pictorial analysis can be found in the art history literature. The purpose of this paper is to suggest that the field can benefit from statistical...
