Do grasses have meristemoids?
Self-renewal is the process by which stem cells divide to produce at least one daughter cell with the same capacity for self-renewal and differentiation as the parent cell (He et al., 2009; Greb & Lohmann, 2016). This daughter cell eventually differentiates to build up new tissues and/or cells....

| Summary: | Self-renewal is the process by which stem cells divide to produce at least one daughter cell with the same capacity for self-renewal and differentiation as the parent cell (He et al., 2009; Greb & Lohmann, 2016). This daughter cell eventually differentiates to build up new tissues and/or cells. Stem cells exist in plants and animals, sharing, despite their substantial divergence at the molecular level, surprising similarities (Sablowski, 2004; Heidstra & Sabatini, 2014). Their enormous potential to produce new cells to grow or replace specialized tissues is having a strong impact on regenerative medicine (Hoang et al., 2022) and in agriculture for crop improvement (Lindsay et al., 2024). Stem cells are maintained in specialized microenvironments, which are known as stem cell niches (Sablowski, 2004; Mitsiadis et al., 2007; Heidstra & Sabatini, 2014). In plants, these niches are mainly located within the meristems and they produce most postembryonic development (Sablowski, 2004; Aichinger et al., 2012; Heidstra & Sabatini, 2014; Hong & Fletcher, 2023). Plant stem cells are also dispersed in the epidermis of the developing leaf and cotyledon of many plant species. These stem cells, named meristemoids (Ms), are responsible for triggering stomatal development after they cross a critical cell size threshold (Gong et al., 2023). |
