Why a parasitic vine can’t take a bite out of tomatoes

Like herbal vampires, dodder plants (Cuscuta sp.) drain the life out of yields the world over. In any case, tomatoes (Solanum lycopersicum) are strangely invulnerable to the parasitic vine’s assaults.

To make sense of how they do it, an examination group from England and Germany hit tomatoes and three other plant species with C. reflexa remove in the lab. Tomatoes completely overcompensated, delivering stress hormones to shield itself from the parasite, while alternate plants neglected to mount a protection.

This recommends tomatoes treat the dodder like an infection, taking prompts from parasite proteins as a notice framework, the group composes July 28 in Science. This affectability follows to a receptor that detects the nearness of a little protein discharged by dodder plants.

This most likely isn’t the main barrier alternative. Some wild tomato species can battle off dodder despite the fact that they’re feeling the loss of the quality behind the receptor, the analysts note. Still, the discoveries could demonstrate helpful in shielding different yields from vampiric vines through hereditary building.
