Molecular evidence of the haploid origin in wheat (Triticum aestivum L.) with Aegilops kotschyi cytoplasm and whole genome expression profiling after haploidization [PDF]

open access: yes, 2014
Aegiolops kotschyi cytoplasmic male sterile system often results in part of haploid plants in wheat (Triticum aestivum L.). To elucidate the origin of haploid, 235 wheat microsatellite (SSR) primers were randomly selected and screened for polymorphism ...

fCUT&Tag‐Seq: An optimized CUT&Tag‐based method for high‐resolution profiling of histone modifications and chromatin‐binding proteins in fungi

open access: yesmLife, EarlyView.
Abstract Histone modifications and chromatin‐binding proteins play crucial roles in regulating gene expression in eukaryotes, with significant implications for fungal pathogenicity and development. However, profiling these modifications or proteins across the genome in fungi remains challenging due to the technical limitations of the traditional ...

Effect of parental genotypes on haploid embryo formation in wheat x maize hybridization [PDF]

open access: yesSelekcija i Semenarstvo, 2005
Wheat x maize hybridization method is an efficient and frequently used system for production of haploids in wheat. With the intention of further improving the efficiency of this method, the aim of this work was to analyze the influence of wheat genotype,

Clinicopathological significance of loss of Y chromosome in male meningiomas

open access: yesThe Journal of Pathology, EarlyView.
Abstract Male meningiomas, comprising approximately 30% of all meningiomas, are more frequently high‐grade and associated with poorer clinical outcomes compared to their female counterparts. Although Y chromosome alterations have been studied in various male‐predominant tumors, a limited number of studies have evaluated their role in meningiomas.

Improving the Efficiency of Colchicine-Based Chromosomal Doubling of Maize Haploids

open access: yesPlants, 2020
Production and use of doubled haploids (DH) is becoming an essential part of maize breeding programs worldwide as DH lines offer several advantages in line development and evaluation.

Tree-valued Fleming-Viot dynamics with mutation and selection

open access: yes, 2012
The Fleming-Viot measure-valued diffusion is a Markov process describing the evolution of (allelic) types under mutation, selection and random reproduction.

Optimum recombination rates for genetic gains in simulated recurrent selection in empirical maize populations. [PDF]

open access: yesPlant Genome
Abstract Meiotic recombination creates new allelic combinations, but it also disrupts favorable parental haplotypes. Our objective was to assess if optimum recombination rates exist in elite maize (Zea mays L.) populations undergoing simulated short‐term and long‐term recurrent selection.

Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.

Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]

open access: yes, 1977
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.
