KARRIKIN INSENSITIVE2-dependent signaling in the liverwort Marchantia polymorpha
The Plant Cell: In a NutshellMizuno et al. show that genes in the KARRIKIN INSENSITIVE2-dependent signaling pathway are conserved in the liverwort Marchantia polymorpha and control early development of the thallus.

Sde1A enables axillary meristem formation at the leaf axil boundary
The Plant Cell: In a NutshellBy Hernán López and Klaus Theres, Max Planck institute for Plant Breeding Research.
López and colleagues identify the gene mutated in the tomato super determinant (sde) mutant, which affects vegetative shoot branching, but not seed set.
Background:
The degree of shoot branching is an important…
NF-YCs mediate plant growth during the dark-to-light transition
The Plant Cell: In a NutshellZhang et al. uncover the roles of NF-YC transcription factors in repressing brassinosteroid biosynthesis and signaling to mediate photomorphogenesis in Arabidopsis.
Background: Seedlings, which germinate in the soil, generally undergo rapid hypocotyl elongation to seek light for growth and development.…
Probing actin-mediated root hair development
The Plant Cell: In a NutshellChin et al. identify SPIRRIG and SCAR/WAVE as molecular determinants of actin-mediated root hair development in Arabidopsis.
Background: Root hairs are tip growing cells that extend the radius of a root to optimize water and nutrient absorption. Root hair development is complex and involves the…
