異数体を含むレンゲ人為同質4倍体集団での全兄弟と半兄弟の共分散の計算 [PDF]

open access: yes, 2008
Full and half sib covariances were investigated in an artificial autotetraploid population with random mating in Astragalus sinicus L.. Since a set of homologous chromosomes is not necessarily involved in aneuploidy, the covariances must be averaged for ...

Spider Eye Development Editing and Silk Fiber Engineering Using CRISPR‐Cas

open access: yesAngewandte Chemie International Edition, EarlyView.
Spiders exhibit unique traits with significant implications for a diversity of fields, and gene editing provides new opportunities for advancing research in these areas. In this study, we developed a CRISPR‐Cas9 protocol for spiders, enabling gene knock‐outs/knock‐ins to study gene function and introduce new phenotypic traits. Abstract CRISPR‐Cas9 gene

Motorized Chromosome Models of Mitosis [PDF]

open access: yesarXiv
During mitosis, near-spherical chromosomes reconfigure into rod-like structures to ensure their accurate segregation to daughter cells. We explore here, the interplay between the nonequilibrium activity of molecular motors in determining the chromosomal organization in mitosis and its characteristic symmetry-breaking events.

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

open access: yesThe Anatomical Record, EarlyView.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...
