“…Root knot nematodes of Meloidogyne spp. are examples of plant parasitic nematodes that cause galls on leguminous roots that affect rhizobial nodulation (El-Bahrawy and Salem, 1989;Wood et al, 2018;Yergaliyev et al, 2020). Meloidogyne incognita produces chemical factors that elicit signal transduction events that result in root knots, in a similar manner that roots nodules are formed through Rhizobium Nod factors (Weerasinghe et al, 2005).…”

Rhizobia are bacteria that exhibit both endophytic and free-living lifestyles. Endophytic rhizobial strains are widely known to infect leguminous host plants, while some do infect non-legumes. Infection of leguminous roots often results in the formation of root nodules. Associations between rhizobia and host plants may result in beneficial or non-beneficial effects. Such effects are linked to various biochemical changes that have far-reaching implications on relationships between host plants and the dependent multitrophic biodiversity. This paper explores relationships that exist between rhizobia and various plant species. Emphasis is on nutritional and phytochemical changes that occur in rhizobial host plants, and how such changes affect diverse consumers at different trophic levels. The purpose of this paper is to bring into context various aspects of such interactions that could improve knowledge on the application of rhizobia in different fields. The relevance of rhizobia in sustainable food systems is addressed in context.

Legumes form two types of root organs in response to signals from microbes: nodules and root galls. In the field, these interactions occur concurrently, and often interact with each other. The outcomes of these interactions vary, and can depend on natural variation in rhizobia and nematode populations in the soil, as well as abiotic conditions. While rhizobia are symbionts that contribute fixed nitrogen to their hosts, parasitic root knot nematodes (RKN) cause galls as feeding structures that consume plant resources without a contribution to the plant. Yet, the two interactions share similarities, including rhizosphere signaling, repression of host defence responses, activation of host cell division and differentiation, nutrient exchange and alteration of root architecture. Rhizobia activate changes in defence and development through Nod factor signaling, with additional functions of effector proteins and exopolysaccharides. RKN inject large numbers of protein effectors into plant cells that directly suppress immune signaling and manipulate developmental pathways. This review examines the molecular control of legume interactions with rhizobia and RKN to elucidate shared and distinct mechanisms of these root-microbe interactions. Many of the molecular pathways targeted by both organisms overlap, yet recent discoveries have singled out differences in the spatial control of expression of developmental regulators that may have enabled activation of cortical cell division during nodulation in legumes. The interaction of legumes with symbionts and parasites highlights the importance of a comprehensive view of root-microbe interactions for future crop management and breeding strategies.
