Effects of local mutations in quadratic iterations [PDF]

open access: yes, 2020
We introduce mutations in replication systems, in which the intact copying mechanism is performed by discrete iterations of a complex quadratic map. More specifically, we consider a "correct" function acting on the complex plane (representing the space ...

Further genetic heterogeneity for autosomal dominant human sutural cataracts [PDF]

open access: yes, 2003
A unique sutural cataract was observed in a 4-generation German family to be transmitted as an isolated autosomal, dominant trait. Since mutations in the gamma-crystallin encoding CRYG genes have previously been demonstrated to be the most frequent ...

A SIMPLE pipeline for mapping point mutations [PDF]

open access: yesPlant Physiology, 2016
Abstract A forward genetic screen is one of the best methods for revealing the regulatory functions of genes. In plants, this technique is highly efficient since it is relatively easy to grow and screen the phenotypes of hundreds or thousands of individuals.

Susceptibility to Acaricides and the Frequencies of Point Mutations in Etoxazole- and Pyridaben-Resistant Strains and Field Populations of the Two-Spotted Spider Mite, Tetranychus urticae (Acari: Tetranychidae)

open access: yesInsects, 2021
The two-spotted spider mite Tetranychus urticae Koch is a major agricultural pest worldwide and is known to rapidly develop resistance to pesticides.

Genetic Correlations in Mutation Processes

open access: yes, 1998
We study the role of phylogenetic trees on correlations in mutation processes. Generally, correlations decay exponentially with the generation number. We find that two distinct regimes of behavior exist.

Dishevelled genes mediate a conserved mammalian PCP pathway to regulate convergent extension during neurulation [PDF]

open access: yes, 2006
The planar cell polarity (PCP) pathway is conserved throughout evolution, but it mediates distinct developmental processes. In Drosophila, members of the PCP pathway localize in a polarized fashion to specify the cellular polarity within the plane of the

Mutation in Populations Governed by a Galton-Watson Branching Process

open access: yes, 2018
A population genetics model based on a multitype branching process, or equivalently a Galton-Watson branching process for multiple alleles, is pre- sented. The diffusion limit forward Kolmogorov equation is derived for the case of neutral mutations.

Point Mutations in Centromeric Histone Induce Post-zygotic Incompatibility and Uniparental Inheritance. [PDF]

open access: yes, 2015
The centromeric histone 3 variant (CENH3, aka CENP-A) is essential for the segregation of sister chromatids during mitosis and meiosis. To better define CENH3 functional constraints, we complemented a null allele in Arabidopsis with a variety of mutant ...

Functional Characterization of the Arabidopsis Ammonium Transporter AtAMT1;3 With the Emphasis on Structural Determinants of Substrate Binding and Permeation Properties

open access: yesFrontiers in Plant Science, 2020
AtAMT1;3 is a major contributor to high-affinity ammonium uptake in Arabidopsis roots. Using a stable electrophysiological recording strategy, we demonstrate in Xenopus laevis oocytes that AtAMT1;3 functions as a typical high-affinity NH4+ uniporter ...

Reduced mutation rate and increased transformability of transposon-free Acinetobacter baylyi ADP1-ISx [PDF]

open access: yes, 2017
The genomes of most bacteria contain mobile DNA elements that can contribute to undesirable genetic instability in engineered cells. In particular, transposable insertion sequence (IS) elements can rapidly inactivate genes that are important for a ...
