The molecular basis of parental conflict driven regulation of endosperm cellularization

The paper identifies maternally expressed auxin response factors that promote endosperm cellularization and regulate seed size, revealing antagonistic parental control over this process.

H2A ubiquitination is essential for Polycomb Repressive Complex 1-mediated gene regulation in Marchantia polymorpha

This study shows that H2A ubiquitination is essential for PRC1 function and H3K27me3 deposition in Marchantia polymorpha, affecting gene and transposable element regulation.

MicroRNA function transitions from regulating developmental genes to transposable elements during the maturation of pollen

The paper analyzes microRNA dynamics during pollen development, showing a shift from regulating developmental genes to controlling transposable elements in mature pollen.

Functional role of Polymerase IV during pollen development in Capsella

Loss of Polymerase IV function in Capsella rubella causes microspore arrest, revealing an important functional role of Polymerase IV during pollen development.

The MADS-box transcription factor PHERES1 controls imprinting in the endosperm by binding to domesticated transposons

This study identifies PHERES1 as a master regulator of imprinted genes in Arabidopsis thaliana endosperm, showing its binding to domesticated transposons that facilitate transcriptional network formation.

Auxin regulates endosperm cellularization in Arabidopsis

This study shows that increased auxin biosynthesis in the endosperm prevents cellularization, causing seed arrest, and identifies auxin's role in hybridization barriers.

microRNA-triggered transposon small RNAs mediate genome dosage response

The paper shows that miR845 targets transposon PBS in Arabidopsis pollen, triggering small RNA accumulation that mediates hybridization barriers and endosperm balance.

Paternal easiRNAs regulate parental genome dosage in Arabidopsis

This study identifies paternal easiRNAs as regulators of the triploid block in Arabidopsis, showing they control DNA methylation and seed viability through imprinted gene expression.
