Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
The FEBS Journal, EarlyView.Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

The Dead Box Helicase YxiN Maintains a Closed Conformation during ATP Hydrolysis
, 2009 DEAD box helicases unwind RNA duplexes at the expense of ATP hydrolysis. Recently, unwinding has been demonstrated in the absence of ATP hydrolysis. Herein, we show that ADP.BeF(x) supports RNA unwinding by YxiN, a DEAD box helicase that specifically ...

, 2017 Structured RNAs and RNA–protein complexes (RNPs) fold through complex pathways that are replete with misfolded traps, and many RNAs and RNPs undergo extensive conformational changes during their functional cycles.

RNA activation in insects: From emerging evidence to molecular applications
Insect Molecular Biology, EarlyView.Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Role of DEAD/DEAH-box helicases in immunity, infection and cancers
Cell Communication and SignalingDEAD/DEAH-box helicases (DDX) are integral RNA-binding proteins within the RNA helicase superfamily 2 (SF2), characterized by distinct DEAD (Asp-Glu-Ala-Asp) and DEAH (Asp-Glu-Ala-His) motifs.

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha
New Phytologist, EarlyView.The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Chromatin Remodelling Complexes in Plant Adaptation to Abiotic Stress: Mechanisms and Perspectives
Plant, Cell &Environment, EarlyView.ABSTRACT As sessile organisms, plants have evolved elaborate epigenetic regulatory networks to adapt to a wide range of abiotic stress. Chromatin remodelling is a core epigenetic regulatory mechanism that refers to the process by which chromatin remodelling complexes mediate dynamic changes in chromatin spatial conformation and DNA accessibility ...
