Patterning

Definition

Patterning describes the processes by which the plan for later development of a plant is laid down. It involves the early establishment of 'prepatterns' of 'morphogens' which form a complex signalling network, which in turn determines further differentiation.

    Polarity establishment during the first zygote asymmetrical division is explored in the brown algae Dictyota. Through transcriptomics and cytological observations, the authors uncover a novel polarization process based on two steps that are controlled by different cues.

    The legume–Rhizobium symbiosis allows nitrogen fixation. Development of nodules is a finely regulated developmental process that involves a DNA demethylase called DEMETER, linking epigenetic regulation and symbiosis.

    An investigation of the molecular mechanism of stomatal development and patterning finds an unexpected signalling mechanism: two signalling peptides (STOMAGEN, a positive regulator of stomatal development; and EPF2, a negative regulator of this process) use the same receptor kinase, ERECTA, to fine-tune stomatal development.

    The mechanisms of sepal/petal/lip determination in orchids remain obscure. Now a study reveals competition between two protein complexes containing different AP3/AGL6 homologues determine the formation of the complex perianth patterns in orchids.

    Asymmetric cell divisions establish the patterning of stomata in maize. Here it is demonstrated that the SCAR/WAVE complex and actin networks are involved in the early polarity establishment of PAN's receptor-like kinases in mother cells before division.
