Loss of E3 ligase HvST1 function substantially increases distal crossover frequency. [PDF]

open access: yesNew Phytol
Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.

XSim: Simulation of Descendants from Ancestors with Sequence Data. [PDF]

open access: yes, 2015
Real or imputed high-density SNP genotypes are routinely used for genomic prediction and genome-wide association studies. Many researchers are moving toward the use of actual or imputed next-generation sequence data in whole-genome analyses.

Toward transparent AI: Predicting strength of fly ash foam composite concrete using explainable ML models

open access: yesStructural Concrete, EarlyView.
Abstract Fly ash foam composite concrete (FFC) is a sustainable, lightweight alternative to traditional concrete. However, accurately predicting its compressive strength (CS) through conventional laboratory methods is challenging due to its non‐linear behavior induced by the addition of foam content and fly ash. Also, the laboratory determination of CS

Cas9 Nickase-Assisted RNA Repression Enables Stable and Efficient Manipulation of Essential Metabolic Genes in Clostridium cellulolyticum

open access: yesFrontiers in Microbiology, 2017
Essential gene functions remain largely underexplored in bacteria. Clostridium cellulolyticum is a promising candidate for consolidated bioprocessing; however, its genetic manipulation to reduce the formation of less-valuable acetate is technically ...

Csm4-dependent telomere movement on nuclear envelope promotes meiotic recombination. [PDF]

open access: yesPLoS Genetics, 2008
During meiotic prophase, chromosomes display rapid movement, and their telomeres attach to the nuclear envelope and cluster to form a "chromosomal bouquet." Little is known about the roles of the chromosome movement and telomere clustering in this phase.

sequenceLDhot: Detecting Recombination Hotspots. [PDF]

open access: yes, 2006
Motivation: There is much local variation in recombination rates across the human genome—with the majority of recombination occuring in recombination hotspots—short regions of around ~2 kb in length that have much higher recombination rates than ...

Multi‐Objective Optimisation Framework for Heterogeneous Federated Learning

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Federated learning is a distributed framework that trains a centralised model using data from multiple clients without transferring that data to a central server. Despite rapid progress, federated learning still faces several unsolved challenges. Specifically, communication costs and system heterogeneity, such as nonidentical data distribution,

ATR/Mec1 prevents lethal meiotic recombination initiation on partially replicated chromosomes in budding yeast

open access: yeseLife, 2013
During gamete formation, crossover recombination must occur on replicated DNA to ensure proper chromosome segregation in the first meiotic division. We identified a Mec1/ATR- and Dbf4-dependent replication checkpoint in budding yeast that prevents the ...

Evidence that masking of synapsis imperfections counterbalances quality control to promote efficient meiosis. [PDF]

open access: yesPLoS Genetics, 2013
Reduction in ploidy to generate haploid gametes during sexual reproduction is accomplished by the specialized cell division program of meiosis. Pairing between homologous chromosomes and assembly of the synaptonemal complex at their interface (synapsis ...
