Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...

Position-dependent inhibition of the cleavage step of pre-mRNA 3'-end processing by U1 snRNP [PDF]

, 2000
The 3' ends of most eukaryotic pre-mRNAs are generated by 3' endonucleolytic cleavage and subsequent polyadenylation. 3'-end formation can be influenced positively or negatively by various factors.

Regulation of alternative polyadenylation by genomic imprinting

, 2008
Maternally and paternally derived alleles can utilize different promoters, but allele-specific differences in cotranscriptional processes have not been reported.

The GSK3/SHAGGY‐like OsGSK3 phosphorylates and inhibits phase separation of OsFCA at Ser‐43 and Ser‐45 to regulate brassinosteroid signaling and rice architecture

New Phytologist, EarlyView.
A working model for GLYCOGEN SYNTHASE KINASE 3‐mediated phosphorylation of FLOWERING CONTROL LOCUS A in the regulation of brassinosteroid signaling and rice growth and development. Summary Brassinosteroid (BR) signaling plays a critical role in rice (Oryza sativa L.) grain development.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, EarlyView.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

Quantitative Control of Transposable Elements: From Genome Plasticity to Immune Regulatory Circuits

Cell Biochemistry and Function, Volume 44, Issue 7, July 2026.
ABSTRACT Transposable elements (TEs) constitute nearly half of the human genome and are increasingly recognized as context‐dependent regulators of genome function rather than passive repetitive DNA. This Review synthesizes classical and recent evidence on TE biology, including TE classification, mechanisms of mobilization, host restriction pathways ...

Inhibition of polyadenylation by stable RNA secondary structure [PDF]

, 1998
The presence of a polyadenylation signal in the repeat (R) region of the HIV-1 genome, which is located at both the 5 ′ and 3 ′ ends of the viral transcripts, requires differential regulation of polyadenylation.

U1 snRNP-Dependent Suppression of Polyadenylation: Physiological Role and Therapeutic Opportunities in Cancer

International Journal of Cell Biology, 2013
Pre-mRNA splicing and polyadenylation are critical steps in the maturation of eukaryotic mRNA. U1 snRNP is an essential component of the splicing machinery and participates in splice-site selection and spliceosome assembly by base-pairing to the 5 ...

Molecular Interplay of PARN and Telomerase: Tail Modifiers and Disease Implications

WIREs RNA, Volume 17, Issue 4, July/August 2026.
Schematic representation of the molecular interplay between PARN, telomerase‐associated, and the involvement of p53 in regulating telomere maintenance and genome stability. The top panel shows how normal PARN levels are involved in regulating p53 levels and balanced telomerase activity through their regulatory interaction with TERC and TERRA, thus ...
