Estimating F-StatisticsAnnual Review of Genetics - Tập 36 Số 1 - Trang 721-750 - 2002
B. S. Weir, William G. Hill
▪ Abstract A moment estimator of θ, the coancestry coefficient for alleles
within a population, was described by Weir & Cockerham in 1984 ( 100 ) and is
still widely cited. The estimate is used by population geneticists to
characterize population structure, by ecologists to estimate migration rates, by
animal breeders to describe genetic variation, and by forensic scientists to
quantify the stren... hiện toàn bộ
The Rules of Engagement in the Legume-Rhizobial SymbiosisAnnual Review of Genetics - Tập 45 Số 1 - Trang 119-144 - 2011
Giles Oldroyd, Jeremy D. Murray, Philip S. Poole, J. Allan Downie
Rhizobial bacteria enter a symbiotic association with leguminous plants,
resulting in differentiated bacteria enclosed in intracellular compartments
called symbiosomes within nodules on the root. The nodules and associated
symbiosomes are structured for efficient nitrogen fixation. Although the
interaction is beneficial to both partners, it comes with rigid rules that are
strictly enforced by the ... hiện toàn bộ
Multiple Roles for Heterochromatin Protein 1 Genes inDrosophilaAnnual Review of Genetics - Tập 43 Số 1 - Trang 467-492 - 2009
Danielle Vermaak, Harmit S. Malik
Heterochromatin is the gene-poor, transposon-rich, late-replicating chromatin
compartment that was first cytologically defined more than 70 years ago. The
identification of heterochromatin protein 1 (HP1) paved the way for a molecular
dissection of this important component of complex eukaryotic genomes. Although
initial studies revealed HP1's key role in heterochromatin maintenance and
function, m... hiện toàn bộ
Rules of Engagement: Molecular Insights from Host-Virus Arms RacesAnnual Review of Genetics - Tập 46 Số 1 - Trang 677-700 - 2012
Matthew D. Daugherty, Harmit S. Malik
Mammalian genes and genomes have been shaped by ancient and ongoing challenges
from viruses. These genetic imprints can be identified via evolutionary analyses
to reveal fundamental details about when (how old), where (which protein
domains), and how (what are the functional consequences of adaptive changes)
host-virus arms races alter the proteins involved. Just as extreme amino acid
conservation... hiện toàn bộ
PROGRAMMED TRANSLATIONAL FRAMESHIFTINGAnnual Review of Genetics - Tập 30 Số 1 - Trang 507-528 - 1996
Philip J. Farabaugh
▪ Abstract Errors that alter the reading frame occur extremely rarely during
translation, yet some genes have evolved sequences that efficiently induce
frameshifting. These sequences, termed programmed frameshift sites, manipulate
the translational apparatus to promote non-canonical decoding. Frameshifts are
mechanistically diverse. Most cause a −1 shift of frames; the first such site
was discove... hiện toàn bộ
Plant Virus Metagenomics: Biodiversity and EcologyAnnual Review of Genetics - Tập 46 Số 1 - Trang 359-369 - 2012
Marilyn J. Roossinck
Viral metagenomics is the study of viruses in environmental samples, using next
generation sequencing that produces very large data sets. For plant viruses,
these studies are still relatively new, but are already indicating that our
current knowledge grossly underestimates the diversity of these viruses. Some
plant virus studies are using thousands of individual plants so that each
sequence can be... hiện toàn bộ
Shufflons: Multiple Inversion Systems and IntegronsAnnual Review of Genetics - Tập 33 Số 1 - Trang 171-191 - 1999
Teruya Komano
▪ Abstract Conservative site-specific recombination functions to create
biological diversity in prokaryotes. Simple site-specific recombination systems
consist of two recombination sites and a recombinase gene. The plasmid R64
shufflon contains seven recombination sites, which flank and separate four DNA
segments. Site-specific recombinations mediated by the product of the rci gene
between any tw... hiện toàn bộ
