The 160 bp insertion in the promoter of Rht-B1i plays a vital role in increasing wheat height

Frontiers in Plant Science, 2016
The extensive use of two alleles (Rht-B1b and Rht-D1b) at the Rht-1 locus in wheat allowed dramatic increases in yields, triggering the so-called Green Revolution. Here, we found that a new natural allelic variation (Rht-B1i) containing a single missense

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Differential Expression of Placental Glucocorticoid Receptors and Growth Arrest-Specific Transcript 5 in Term and Preterm Pregnancies: Evidence for Involvement of Maternal Stress

Obstetrics and Gynecology International, 2014
Pregnancy-specific stress predicts birth outcomes. We hypothesized that there is a maternal stress-GR interaction that can influence fetal birth weight.

Centromere function in asymmetric cell division in Drosophila female and male germline stem cells

Open Biology, 2021
The centromere is the constricted chromosomal region required for the correct separation of the genetic material at cell division. The kinetochore protein complex assembles at the centromere and captures microtubules emanating from the centrosome to ...

Securin Is Not Required for Chromosomal Stability in Human Cells [PDF]

, 2005
Abnormalities of chromosome number are frequently observed in cancers. The mechanisms regulating chromosome segregation in human cells are therefore of great interest.

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Functional interplay between condensin I and topoisomerase IIα in single-molecule DNA compaction

Nature Communications
Condensin I and topoisomerase IIα (topo IIα) are chromosomal ATPases essential for mitotic chromosome assembly. Mechanistically how the two ATPases cooperate to assemble mitotic chromosomes remains unknown.

Simultaneous loading of PCR-based multiple fragments on mouse artificial chromosome vectors in DT40 cell for gene delivery

Scientific Reports, 2022
Homology-directed repair-mediated knock-in (HDR-KI) in combination with CRISPR-Cas9-mediated double strand break (DSB) leads to high frequency of site-specific HDR-KI. While this characteristic is advantageous for generating genetically modified cellular

Sex chromosome positions in human interphase nuclei as studied by in situ hybridization with chromosome specific DNA probes [PDF]

, 1984
Two cloned repetitive DNA probes, pXBR and CY1, which bind preferentially to specific regions of the human X and Y chromosome, respectively, were used to study the distribution of the sex chromosomes in human lymphocyte nuclei by in situ hybridization ...
