A common switch used by plants and animals

Article Abstract:

Comparisons of animals and plant embryogenesis usually focus on their differences: massive cell movements versus cell constrained by walls, organs developed in utero versus continued organogenesis. The regulation of the internal trafficking of the plant hormone auxin and discovery of a gene hinting at intriguing similarities between plants and animals development are discussed.

Adam meets Eph: An ADAM substrate recognition module acts as a molecular switch for Ephrin cleavage in trans

Article Abstract:

The functional studies of the structure of ADAM10 disintegrin and cysteinerich domains defined an essential substrate-recognition module for functional interaction of ADAM10 with the ephrin-A5/EphA3 complex. Data suggested a simple mechanism for regulating ADAM10-mediated ephrin proteolysis, which ensured that only Eph bound ephrins were recognized and cleaved.

Not just another hole in the wall: Understanding intercellular protein trafficking

Article Abstract:

Direct signaling and exchange of macromolecules between cells is possible through plasmodesmata in plants. The developments that took place in cell-to-cell trafficking of macromolecules in plants and animals are reviewed.
