The role of XAL1 in the root cell dynamics underpinning root growth

Morphogenesis depends on the modulation of cell proliferation and differentiation. The reverse genetics approach of García-Cruz et al. reveals that such modulation is dynamically adjusted in response to various signals via a complex transcriptional regulatory network that mediates between such signals and cell-cycle regulation and cell-fate decisions resulting in proliferation, growth or…
