Three levels of heterogeneity - growth of Arabidopsis leaf epidermis.

ABSTRACT:

Background

Growth of leaf epidermis is symplastic, i.e. cell contacts are preserved, but strongly heterogeneous because of variation in cell identity and differentiation status. Heterogeneous growth requires coordination to allow a predictable leaf shape to be formed. Here we investigate growth heterogeneity and coordination using expanding leaf epidermis of Arabidopsis (Arabidopsis thaliana) as a model system. We first analyse relationships between heterogeneity of epidermis growth at different scales: from subcellular via cellular to tissue scale. Next, based on the heterogeneity analysis, we verify the hypothesis that growth heterogeneity and coordination are affected by microtubule defects in mor1-1 mutant treated with high temperature.
