Plant stem cell

Plant stem cells are innately undifferentiated cells located in the meristems of plant. They serve as the origin of plant vitality, as they maintain themselves while providing a steady supply of precursor cells to form differentiated tissues and organs in the plant.

    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.

    The vascular cambium is a lateral meristem that is particularly active during secondary growth. Here, several signalling pathways (peptide, receptor, auxin and cytokinin) are linked together to explain how vascular development is regulated.

    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.

    Sequencing of nested branches from a 234-year-old oak tree reveals a low number of somatic mutations accumulating during its lifetime, implying that mechanisms are in place to reduce these potentially deleterious mutations during ageing.
