    The authors show that gaseous Nitric Oxide (NO) promotes transit amplifying cell fate in the Arabidopsis shoot meristem. NO acts by modifying AGO4-WUSCHEL protein interactions in stem cells, directly linking NO signaling with DNA methylation.

    Stomatal development is regulated by multiple intrinsic developmental and environmental signals. Here, the authors show that spatially patterned hydrogen peroxide activates the energy sensor SnRK1 to stabilize the SPCH transcription factor and optimize stomatal development in Arabidopsis.

    WUSCHEL is a critical regulator of stem cell homeostasis at shoot apical meristems. Here the authors show that CLV3 regulates WUSCHEL by not only repressing WUSCHEL transcription but also by controlling nuclear export of WUSCHEL and therefore its diffusion between adjacent cells.

    The WUSCHEL transcription factor promotes plant stem cell proliferation. Here the authors show that the maize Bif3 mutant contains a duplication of the ZmWUS1 locus leading to cytokinin hypersensitivity and overproliferation at the shoot meristem demonstrating the role of WUSCHEL in maize and how structural variation can impact plant morphology.

    WUSCHEL is a homeodomain transcription factor that is essential for stem cell maintenance in the plant shoot apical meristem. Here, via structural and biochemical approaches, Sloan et al. show that strong WUSCHEL binding to preferential target motifs can be attributed to dimer formation that stabilizes DNA binding.

    Stem-cell-specific genes regulate processes such as maintenance, identity and/or division. Here, the authors show that in the Arabidopsis root TCX2, a gene expressed across different stem cell populations (a stem-cell-ubiquitous gene), controls division and identity by regulating stem-cell-type-specific networks.

    Spatial control of auxin signaling maintains a balance between stem-cell self-renewal and differentiation at the plant shoot apex. Here Ma et al. show that rheostatic control of auxin response by the WUSCHEL transcription factor maintains stem cells by conferring resistance to auxin mediated differentiation.

    The shoot apical meristem (SAM) maintains stem cells and generates new leaves and flowers from its periphery. Here via spatially resolved translatome profiling, Tian et al. define distinct molecular signatures of different SAM and leaf domains and identify regulators of axillary meristem initiation.

    Auxin activity controls plant stem cell function. Here the authors show that in the cambium, moderate auxin activity restricts cambial stem cell number via ARF5-dependent repression of the stem‐cell‐promoting factor WOX4, while ARF3 and ARF4 promote cambial activity outside of the WOX4‐expression domain.

    In Arabidopsis, the timing of floral meristem termination is determined by AGAMOUS. Here, the authors show that the CRC transcription factor, itself a direct target of AGAMOUS, coordinates meristem termination with subsequent gynoecium formation partly by repressing TRN2 expression and regulating auxin homeostasis.

    Land plants and metazoans are both able to reprogram differentiated cells to stem cells under certain circumstances. Here the authors show that the moss CSP1 protein, which shares conserved domains with the mammalian pluripotent stem cell factor Lin28, promotes reprogramming of leaf cells to apical stem cells.
