The most comprehensive genetic analysis ever of domesticated grape:

Citrus roots sending out their own SOS:
Substances released into the soil by citrus tree roots when chewed on by insect pests could lead to new ways of improving the effectiveness of roundworm "first responders," according to findings by ARS scientists and their university colleagues who identified several citrus chemicals, including terpenes, which attract Steinernema riobrave, Heterorhabditis indica and other beneficial nematode species that prey on citrus root weevils.
