Auxin regulates shoot stem cells
Plant Science Research WeeklyAuxin and cytokinin play critical roles in determination of cell fate in the shoot apical meristem (SAM). Until now auxin's role was thought to be confined to the peripheral zone (PZ), promoting cell differentiation and organogenesis, mediated by AR5/MP. However, studies using GC-MS have shown the presence…
Co-expression networks for strawberry flower and fruit development
Plant Science Research WeeklyThe diploid strawberry (Fragaria vesca) is a useful model system for understanding non-climacteric ripening and seed-to-fruit cross-tissues communication. Previously, spatial and temporal transcriptome data from the strawberry fruit and flowers was generated. Shahan and colleagues combine the transcriptome…
Function of m6A in Arabidopsis
Research, The Plant Cell, The Plant Cell: In a NutshellWei et al. Study m6A binding protein ECT2 in Arabidopsis. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00934

Background: N6-methyladenosine (m6A) is the most abundant chemical modification of eukaryotic messenger RNA (mRNA). The regulation of m6A modification plays important…
Decoding RNA Methylation Regulates Trichome Branching
Research, The Plant Cell, The Plant Cell: In a NutshellScutenaire et al. show that a YTH domain protein acts as a reader of m6A mRNA modifications, thereby playing crucial roles in trichome branching, likely by acting on mRNAs in the cytosol. Plant Cell (2018). https://doi.org/10.1105/tpc.17.00854
