Plant stem cell

Definition

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.

    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.

    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.

    Plants can regenerate tissues after injury. The heterodimeric transcription factor complex ERF115–PAT1 is activated by the cell death of neighbouring cells, and is crucial for stem cell replenishment and the high regenerative potential of plants.

    As in animals, plant stem cells reside in stem cell niches, which produce signals that regulate the balance between self-renewal and differentiation into new tissues. Continuous organ production that is characteristic of plant growth requires a robust regulatory network to maintain this balance. Elucidating this network provides an opportunity to compare plant and animal stem cell strategies.
