A highly mutable GST is essential for bract colouration in Euphorbia pulcherrima Willd. Ex Klotsch

open access: yesBMC Genomics, 2021
Background Mutation breeding is an extraordinary tool in plant breeding to increase the genetic variability, where mutations in anthocyanin biosynthesis are targets to generate distinctive phenotypes in ornamental species.

Control of astrocyte progenitor specification, migration and maturation by Nkx6.1 homeodomain transcription factor. [PDF]

open access: yes, 2014
Although astrocytes are the most abundant cell type in the central nervous system (CNS), little is known about their molecular specification and differentiation.

Correspondence between neuroevolution and gradient descent [PDF]

open access: yes, 2020
We show analytically that training a neural network by conditioned stochastic mutation or neuroevolution of its weights is equivalent, in the limit of small mutations, to gradient descent on the loss function in the presence of Gaussian white noise. Averaged over independent realizations of the learning process, neuroevolution is equivalent to gradient

Empirical Study of Concurrency Mutation Operators for Java [PDF]

open access: yes, 2010
Mutation testing is a white-box fault-based software testing technique that applies mutation operators to modify program source code or byte code in small ways and then runs these modified programs (i.e., mutants) against a test suite in order to measure

BRAF, KIT, and NRAS Mutations of Acral Melanoma in White Patients

open access: yesAmerican Journal of Clinical Pathology, 2020
Abstract Objectives Malignant acral melanoma (AM) is relatively infrequent in white patients. Molecular investigations have returned variable results regarding the mutational pattern. We sought to describe the mutation profile and clinicopathologic features of AM.

White coat color of a Black Angus calf attributed to an occurrence of the delR217 variant of \u3ci\u3eMITF\u3c/i\u3e [PDF]

open access: yes, 2023
A white calf, with minimal pigmented markings, was born to two registered Black Angus parents. Given the possibility of an unknown recessive or de novo dominant mutation, whole-genome sequencing was conducted on the trio of individuals.

Case Report: A Homozygous Mutation (p.Y62X) of Phospholipase D3 May Lead to a New Leukoencephalopathy Syndrome

open access: yesFrontiers in Aging Neuroscience, 2021
Leukodystrophies are a heterogeneous group of inherited disorders with highly variable clinical manifestations and pathogenetic backgrounds. At present, variants in more than 20 genes have been described and may be responsible for different types of ...

Mutation-Based Adversarial Attacks on Neural Text Detectors [PDF]

open access: yesarXiv, 2023
Neural text detectors aim to decide the characteristics that distinguish neural (machine-generated) from human texts. To challenge such detectors, adversarial attacks can alter the statistical characteristics of the generated text, making the detection task more and more difficult.

Structural MRI predicts clinical progression in presymptomatic genetic frontotemporal dementia: findings from the GENetic Frontotemporal dementia Initiative cohort [PDF]

open access: yes, 2023
Bocchetta et al. quantified brain anomalies on MRI in a large cohort of C9orf72, MAPT, and GRN mutation carriers. They defined the imaging markers associated with the largest clinical and behavioral changes over one year in presymptomatic carriers ...

The albinism of the feral Asinara white donkeys (Equus asinus) is determined by a missense mutation in a highly conserved position of the tyrosinase (TYR) gene deduced protein.

open access: yesAnimal Genetics, 2016
A feral donkey population (Equus asinus), living in the Asinara National Park (an island north-west of Sardinia, Italy), includes a unique white albino donkey subpopulation or colour morph that is a major attraction of this park.
