Cells of the xanthophore lineage form projections that allow them to communicate with other pigment cells during adult pigment pattern formation in zebrafish, but not in the closely-related pearl danio.

Free, extracellular dispersal of Wnt proteins generates a long-range gradient during animal development and is required for signaling.

A study of solute and macromolecule trafficking in plants reveals a previously undescribed route for carbon distribution in growing root tissues.

Cohesin is required for the expression of neuronal genes that engage in long chromatin loops, while short-range enhancer-promoter loops can form in the absence of cohesin.

BDNF axonal signaling regulates protein synthesis in neuronal cell bodies leading to dendritic arborization through dynein-dependent transport of signaling endosomes.

The long-distance flight of locusts is greatly facilitated by a muscle-abundantly expressed Hif-1α splice variant, which remains active in normoxia and scavenges flight-induced reactive oxygen species by upregulating the expression of DJ-1 (PARK 7).

Direct interaction between Hedgehog-sending and Hedgehog-receiving cytonemes is a fundamental mechanism for morphogen transfer and gradient establishment.

Ligand capture by cell surface receptor complexes sets the shape of the Nodal signaling pattern in zebrafish.

The glypicans Dally-like protein and Dally reveal functional non-redundancy of the Hedgehog co-receptors Boi and Ihog through independent interactions and specifically regulate cytoneme dynamics via the Ihog FNIII domain, thus setting long-range signaling.

Measurements of physiological and geometrical parameters of the sieve tube system in Ipomoea nil provide strong support for pressure driven mass flow.
