Kinetochore Structure: Pulling Answers from Yeast

, 2012
Despite the identification of multiple kinetochore proteins, their structure and organization has remained unclear. New work uses electron microscopy to visualize isolated budding yeast kinetochore particles and reveal the kinetochore structure on ...

Dissecting the genetic basis of climatic adaptation in wild relatives (Malus baccata) for climate‐resilient apple breeding

Journal of Integrative Plant Biology, EarlyView.
This comprehensive map of genetic variation in wild apple (Malus baccata) and set of key genes associated with adaptation to temperature, precipitation, and soil properties establishes a foundation for breeding climate‐resilient apple cultivars and conserving the genetic resources of wild crop relatives.

Meiosis-specific distal cohesion site decoupled from the kinetochore

Nature Communications
Primary constriction of the M-phase chromosome serves as a marker for the kinetochore position. Underlying this observation is the concept that the kinetochore is spatially linked with the pericentromere where sister-chromatids are cohered. Here, we find

Investigating the Role of Inner Kinetochore Higher-Order Assembly in Kinetochore Function

, 2023
Cells are the basic building blocks of life. As a result, every organism depends on cell division to survive and reproduce. To divide, eukaryotes use a genetic program called the cell cycle, which coordinates the steps required to grow a cell and divide ...

Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

Journal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

R‐Loops Mediated Odontogenic Differentiation of hDPSCs by Activating the cGAS‐STING Pathway Under Inflammatory Microenvironment

Oral Diseases, EarlyView.
ABSTRACT Background R‐Loops are three‐stranded DNA/RNA hybrids implicated in immune responses. Their role in mesenchymal stem cell differentiation, particularly in dental pulp regeneration under inflammation, remains unclear. Methods Rat pulpo‐dentinal complex (PDC) injury models and LPS‐stimulated human dental pulp stem cells (hDPSCs) were used.

High‐Contiguity Haplotype‐Resolved Genome Assembly of the Hexaploid Actinidia valvata Rootstock Sheds Light on Waterlogging Resistance Gene

Plant Biotechnology Journal, EarlyView.
ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Cell cycle dependent methylation of Dam1 contributes to kinetochore integrity and faithful chromosome segregation.

PLoS Genetics
The kinetochore, a megadalton structure composed of centromeric (CEN) DNA and protein complexes, is required for faithful chromosome segregation in eukaryotes.

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...
