SnRK2.4 and SnRK2.10 redundantly control developmental leaf senescence by sustaining ABA production and signaling

This study shows SnRK2.4 and SnRK2.10 promote leaf senescence by increasing ABA production and modulating signaling pathways in Arabidopsis.

Chromatin crosstalk between HDA19 and NuA4 sets thresholds for stress gene activation in Arabidopsis

This study shows that HDA19 and NuA4 interact to regulate stress gene activation in Arabidopsis by modulating H3K9ac and H2A.Zac, with H3K9ac being the primary driver of transcription.

The Arabidopsis deNADding enzyme DXO1 modulates the plant immunity response.

This study shows that the Arabidopsis DXO1 enzyme's catalytic activity and N-terminal domain regulate plant immunity by affecting gene expression and defense responses against Pseudomonas syringae.

Chromatin retained MUSHER lncRNA integrates ABA and DOG1 signalling pathways to enhance Arabidopsis seeds dormancy.

The paper identifies MUSHER, a chromatin-retained lncRNA that integrates ABA and DOG1 pathways to enhance Arabidopsis seed dormancy through distinct mechanisms.

Arabidopsis DXO1 affects the processing of precursors of cytoplasmic and chloroplast ribosomal RNA.

This study shows Arabidopsis DXO1 regulates ribosomal protein gene expression and is essential for rRNA precursor processing in both nuclear and chloroplast pathways.

Sucrose-responsive osmoregulation of plant cell size by a long non-coding RNA

The paper identifies CARMA as a long non-coding RNA that regulates CANAR expression in the phloem to control cell size and vascular tissue formation in response to sugar and osmotic stress.

The UBP5 histone H2A deubiquitinase counteracts PRC2-mediated repression to regulate Arabidopsis development and stress responses

This study identifies UBP5 as an interactor of PRC2 in Arabidopsis, showing it regulates development and stress responses by counteracting PRC2-mediated repression through H2Aub erasure.

Arabidopsis spliceosome factor SmD3 modulates immunity to Pseudomonas syringae infection

This study shows that Arabidopsis SmD3 is involved in plant immunity by regulating mRNA splicing of pathogenesis factors and affecting stomatal immunity.
