The symbiosis between rhizobia and legumes is characterized by a complex molecular dialogue in which the bacterial NodD protein plays a major role due to its capacity to activate the expression of the nodulation genes in the presence of appropiate fl

The symbiosis between rhizobia and their host legumes is initiated by a complex molecular dialogue in which the activation of bacterial NodD proteins by appropriate plant flavonoids triggers the expression of the bacterial nodulation (nod) genes. The

Rhizobium tropici CIAT 899 is a broad-host-range rhizobial strain that establishes symbiotic interactions with legumes and tolerates different environmental stresses such as heat, acidity, or salinity. This rhizobial strain produces a wide variety of
