Plants use calcium to convey internal warning of attacking aphids

Scientists at the John Innes Centre have discovered how plants send internal warning signals in response to attack by aphids.

They found that when the insect feeds on a leaf it triggers the plant to admit calcium into the damaged cells. This small flux of calcium prompts the plant to signal that an attack is underway, and a larger amount of calcium is then mobilised from within the cell.

International scientific alliance launched for crop improvement in sub-Saharan Africa
