Competitive binding of antagonistic peptides fine-tunes stomatal patterning
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.

Roots respond to an inner calling
In plant roots, patterning of two types of water-conducting xylem tissue is determined by a signalling system that involves the reciprocal dance of a mobile transcription factor and mobile microRNAs.
