Utilizing Genomic Selection for Wheat Population Development and Improvement
Agronomy, 2022 Wheat (Triticum aestivum L.) breeding programs can take over a decade to release a new variety. However, new methods of selection, such as genomic selection (GS), must be integrated to decrease the time it takes to release new varieties to meet the ...

Complexity Theory and Genetics: The Computational Power of Crossing Over
Information and Computation, 2001 AbstractWe study the computational power of systems where information is stored in independent strings and each computational step consists of exchanging information between randomly chosen pairs. To this end we introduce a population genetics model in which the operators of selection and inheritance are effectively computable (in polynomial time on ...

FEBS Letters, EarlyView.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Stochastic Model for Genetic Recombination because of Crossing over and Chromatid Exchange
International Journal of Computer Applications, 2013 Genetic recombination by crossing over and chromatid exchange in eukaryotes is one of the major events leading to variance, among individuals of a population set. Therefore, quantification of the recombination would be central to the understanding of the genetic diversity, genealogical differences, disease variants and its maintenance within the ...

Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance An important process in sexual organisms is the shuffling of maternal and paternal DNA in gametes by both crossing over and independent assortment of homologous chromosomes.

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Heritability and Genetic Variance Components in Sunflower Single Cross Hybrids [PDF]
Journal of Agricultural Science and Sustainable Production, 2015 In order to estimate genetic parameters in 16 Sunflower single cross hybrids obtained from crossing of 4 cytoplasmic male sterile and 4 fertility restorer lines, a North Carolina Design II was conducted using RCBD design with 3 replications at Khoy ...

High throughput sequencing reveals alterations in the recombination signatures with diminishing Spo11 activity. [PDF]
PLoS Genetics, 2013 Spo11 is the topoisomerase-like enzyme responsible for the induction of the meiosis-specific double strand breaks (DSBs), which initiates the recombination events responsible for proper chromosome segregation.

Genetic drift opposes mutualism during spatial population expansion [PDF]
Proc. Natl. Acad. Sci. USA 111, 1037-1042 (2014), 2014 Mutualistic interactions benefit both partners, promoting coexistence and genetic diversity. Spatial structure can promote cooperation, but spatial expansions may also make it hard for mutualistic partners to stay together, since genetic drift at the expansion front creates regions of low genetic and species diversity. To explore the antagonism between

Crossing-Over in a Hypervariable Species Preferentially Occurs in Regions of High Local Similarity
Molecular biology and evolution, 2014 Recombination between double-stranded DNA molecules is a key genetic process which occurs in a wide variety of organisms. Usually, crossing-over (CO) occurs during meiosis between genotypes with 98.0–99.9% sequence identity, because within-population ...
