“…An ethylene‐insensitive mutant of M. truncatula , Mtein2 (formerly called sickle ), has a hypernodulation phenotype (Penmetsa et al, ; Penmetsa & Cook, ). Likewise, simultaneous suppression of the two L. japonicus homologues, LjEIN2‐1 and LjEIN2‐2 , causes hypernodulation (Miyata, Kawaguchi, & Nakagawa, ), as does a mutation in the ethylene binding domain of the membrane‐localized ethylene receptor, LjETR1 (Miyata & Nakagawa, ). LjEIN2a (i.e., LjEIN2‐2 ) single mutants exhibit a classical ethylene insensitive phenotype but not hypernodulation due to redundancy with LjEIN2b (i.e., LjEIN2‐1 ; Desbrosses & Stougaard, ; Chan, Biswas, & Gresshoff, ).…”

Global demand to increase food production and simultaneously reduce synthetic nitrogen fertilizer inputs in agriculture are underpinning the need to intensify the use of legume crops. The symbiotic relationship that legume plants establish with nitrogen-fixing rhizobia bacteria is central to their advantage. This plant-microbe interaction results in newly developed root organs, called nodules, where the rhizobia convert atmospheric nitrogen gas into forms of nitrogen the plant can use. However, the process of developing and maintaining nodules is resource intensive; hence, the plant tightly controls the number of nodules forming. A variety of molecular mechanisms are used to regulate nodule numbers under both favourable and stressful growing conditions, enabling the plant to conserve resources and optimize development in response to a range of circumstances. Using genetic and genomic approaches, many components acting in the regulation of nodulation have now been identified. Discovering and functionally characterizing these components can provide genetic targets and polymorphic markers that aid in the selection of superior legume cultivars and rhizobia strains that benefit agricultural sustainability and food security. This review addresses recent findings in nodulation control, presents detailed models of the molecular mechanisms driving these processes, and identifies gaps in these processes that are not yet fully explained.

The two-component system (TCS), which is one of the most evolutionarily conserved signaling pathway systems, has been known to regulate multiple biological activities and environmental responses in plants. Significant progress has been made in characterizing the biological functions of the TCS components, including signal receptor histidine kinase (HK) proteins, signal transducer histidine-containing phosphotransfer proteins, and effector response regulator proteins. In this review, our scope is focused on the diverse structure, subcellular localization, and interactions of the HK proteins, as well as their signaling functions during development and environmental responses across different plant species. Based on data collected from scientific studies, knowledge about acting mechanisms and regulatory roles of HK proteins is presented. This comprehensive summary ofthe HK-related network provides a panorama of sophisticated modulating activities of HK members and gaps in understanding these activities, as well as the basis for developing biotechnological strategies to enhance the quality of crop plants.
