Open source tools for large-scale neuroscience
New technologies for monitoring and manipulating the nervous system promise exciting biology but pose challenges for analysis and computation. Solutions can be found in the form of modern approaches to distributed computing, machine learning, and interactive visualization. But embracing these new technologies will require a cultural shift: away from independent efforts and proprietary methods a...
متن کاملRecurrence of Chromosome Rearrangements and Reuse of DNA Breakpoints in the Evolution of the Triticeae Genomes
Chromosomal rearrangements (CRs) play important roles in karyotype diversity and speciation. While many CR breakpoints have been characterized at the sequence level in yeast, insects, and primates, little is known about the structure of evolutionary CR breakpoints in plant genomes, which are much more dynamic in genome size and sequence organization. Here, we report identification of breakpoint...
متن کاملSequencing and comparative analyses of Aegilops tauschii chromosome arm 3DS reveal rapid evolution of Triticeae genomes.
Bread wheat (Triticum aestivum, AABBDD) is an allohexaploid species derived from two rounds of interspecific hybridizations. A high-quality genome sequence assembly of diploid Aegilops tauschii, the donor of the wheat D genome, will provide a useful platform to study polyploid wheat evolution. A combined approach of BAC pooling and next-generation sequencing technology was employed to sequence ...
متن کاملConservation of fine-scale DNA marker order in the genomes of rice and the Triticeae.
DNA markers distribute over large chromosomal regions exhibit conservation of order (collinearity) in different cereal species, but it is not known whether this is maintained on a finer scale, i.e. < or = 2 cM. To address this, sets of two or more genetically linked DNA markers were localised to yeast artificial chromosomes containing rice DNA inserts. Linkage analysis of these DNA markers in b...
متن کاملRapid genome evolution revealed by comparative sequence analysis of orthologous regions from four triticeae genomes.
Bread wheat (Triticum aestivum) is an allohexaploid species, consisting of three subgenomes (A, B, and D). To study the molecular evolution of these closely related genomes, we compared the sequence of a 307-kb physical contig covering the high molecular weight (HMW)-glutenin locus from the A genome of durum wheat (Triticum turgidum, AABB) with the orthologous regions from the B genome of the s...
