Cell biology: Lipid switches and traffic control

Transport vesicles that bud from one cell membrane must change identity before fusing with another. During the process of clathrin-mediated endocytosis, various lipid phosphates mediate this identity change.

Atlas maps 90,000 gene switches in plants

U. TORONTO (CAN) — A new genomic map may help explain why some plants can survive a freeze and others are sensitive to even the slightest drop in temperature.Those that flourish activate specific genes at just the right time—but the way gene activa…
