Small RNAs in the maillot jaune: transcriptional analysis of the plant cell cycle
Research, The Plant Cell, The Plant Cell: In BriefThe cell cycle is a tightly coordinated dance with the ultimate goal of dividing one cell into two. Eukaryotic cells tend to divide in the same general pattern, broadly reduced to four phases; cells increase organelle content in the G1 phase, DNA replication occurs in S phase, cells grow in size and…

Physcomitrella STEMIN transcription factor induces stem cell formation with epigenetic reprogramming (Nature Plants)
Plant Science Research WeeklyInsights into transcription factors (TFs) in non-flowering plants are increading thanks to the establishment of new bryophyte model organisms. In new work, Ishikawa et al. present STEMIN1, a Physcomitrella patens TF belonging to an uncharacterized subgroup of the AP2/ERF family. Physcomitrella undergo…
Arabidopsis endosperm response to paternal genome dosage is regulated by small RNA pathway (Plant Cell)
Plant Science Research WeeklyThe endosperm, a tissue that transfers nutrients from maternal tissue to the embryo, is normally triploid, with two copies of the maternal genome and one of the paternal genome. Excess paternal genomes usually leads to endosperm abnormalities and seed abortion. Previous studies have shown that the RNA…
An insulator of CLE-signaling boosts cell-differentiation in protophloem formation
Plant Science Research WeeklyWaddington’s epigenetic landscape, a famous metaphor in developmental biology, depicts how a stem cell progresses from an undifferentiated state to a differentiated one. To some degree this metaphor can also be applied to root cell differentiation. It’s well-known that the CLE-45 peptide and its…
Cytokinin functions as an asymmetric and anti-gravitropic signal in lateral roots (Nature Comms)
Plant Science Research WeeklyLateral roots help plants to explore the soil and environmental conditions. Waidmann et al. took advantage of natural variants to understand lateral growth angle by analyzing gravitropic set point angle (GSA). Using Col-0 as a reference, lines that over- or under-respond (steeper or shallower root angle)…
