The greenbeard gene tgrB1 regulates altruism and cheating in Dictyostelium discoideum.

Nature communications - 11 May 2024

Katoh-Kurasawa Mariko, Lehmann Peter, Shaulsky Gad

Abstract excerpt

Greenbeard genetic elements encode rare perceptible signals, signal recognition ability, and altruism towards others that display the same signal. Putative greenbeards have been described in various organisms but direct evidence for all the properties in one system is scarce. The tgrB1-tgrC1 allorecognition system of Dictyostelium discoideum encodes two polymorphic membrane proteins which protect cells from...
