“…Mesorhizobium ciceri and M. mediterraneum are widely prevalent in many countries except China (Zhang et al 2012b). On the other hand, to date, M. muleiense was only reported in Xinjiang, Gansu and Ningxia of China (Zhang et al 2012a;Zhang et al 2017;Zhang et al 2020) and M. wenxiniae only in Gansu of China (Zhang et al 2018). These data demonstrate that various chickpea-nodulating mesorhizobia have evolved in different ecogeographic regions.…”

“…In China, chickpea was first cultivated in Xinjiang (northwest) around 2500 years ago, and then it was introduced into other areas including the provinces of Gansu in the north‐central China, Henan and Shandong in the east, Inner‐Mongolia in the north and Yunnan, Sichuan and Chongqing in south‐central China (Zhang et al . 2020).…”

“…The majority of this crop is grown on marginal lands because it can adapt to a wide variety of soils and it demands low cultivation input, offering myriad benefits for sustainable small farm production systems (Ozdemir et al 2021). In China, chickpea was first cultivated in Xinjiang (northwest) around 2500 years ago, and then it was introduced into other areas including the provinces of Gansu in the north-central China, Henan and Shandong in the east, Inner-Mongolia in the north and Yunnan, Sichuan and Chongqing in south-central China (Zhang et al 2020).…”

The present study aimed to compare the competitive advantage of two chickpea nodulating rhizobia strains (an indigenous strain Mesorhizobium muleiense CCBAU 83963 T and an introduced strain Mesorhizobium ciceri USDA 3378) in different soils originated from new chickpea cultivation areas of China. The results showed that USDA 3378 had a significant competitive advantage in nodulation, with nodulation occupation rates ranging from 84Á6% to 100% in all the sampled soils. According to the efficiency of symbiosis under single inoculation, chickpea plants inoculated with USDA 3378 showed better symbiotic performance based on the plant dry weight, leaf chlorophyll content and nodule numbers. The chickpea plants inoculated with USDA 3378 formed nodules about 2 days earlier than those inoculated with CCBAU 83963 T . The higher growth in media and the stronger adsorption on chickpea roots of USDA 3378 when mixed with CCBAU 83963 T may explain why USDA 3378 shows a competitive advantage. The results from this study will contribute towards the development of effective chickpea rhizobial inoculants for soil conditioning and more environmentally friendly production of chickpeas in China.

“…Until now no other host plant, even the extremely promiscuous medicinal legume S. flavescens (Jiao et al 2015), was recorded to be infected effectively by the host-specific chickpea mesorhizobia, which bear the specific nodulation gene (nodC). The nodulation and nitrogen-fixing genes (such as nodC and nifH) of chickpea rhizobia are extremely conserved (Chen 2019a;Zhang et al 2020b) in different Mesorhizobium species (Laranjo et al 2008;Zhang et al 2018;Benjelloun et al 2019) distributed in different countries and sites (Greenlon et al 2019;Zhang et al 2020a;Zhang et al 2020b). Rhizobia associating with alfalfa, pea, clover (Trifolium sp.…”

SummaryCurrently, symbiotic rhizobia (sl., rhizobium) refer to the soil bacteria in aand b-Proteobacteria that can induce root and/or stem nodules on some legumes and a few of nonlegumes. In the nodules, rhizobia convert the inert dinitrogen gas (N 2 ) into ammonia (NH 3 ) and supply them as nitrogen nutrient to the host plant. In general, this symbiotic association presents specificity between rhizobial and leguminous species, and most of the rhizobia use lipochitooligosaccharides, so called Nod factor (NF), for cooperating with their host plant to initiate the formation of nodule primordium and to inhibit the plant immunity. Besides NF, effectors secreted by type III secretion system (T3SS), exopolysaccharides and many microbeassociated molecular patterns in the rhizobia also play important roles in nodulation and immunity response between rhizobia and legumes. However, the promiscuous hosts like Glycine max and Sophora flavescens can nodulate with various rhizobial species harbouring diverse symbiosis genes in different soils, meaning that the nodulation specificity/efficiency might be mainly determined by the host plants and regulated by the soil conditions in a certain cases. Based on previous studies on rhizobial application, we propose a '1+nÀN' model to promote the function of symbiotic nitrogen fixation (SNF) in agricultural practice, where '1' refers to appreciate rhizobium; '+n' means the addition of multiple trace elements and PGPR bacteria; and 'ÀN' implies the reduction of chemical nitrogen fertilizer. Finally, open questions in the SNF field are raised to future think deeply and researches. Current rhizobial taxonomic outline and use of genome sequence in rhizobial systematicsCurrently, all the symbiotic nitrogen-fixing bacteria associating with legumes are found in the Phylum Proteobacteria, mainly in the Classes Alphaproteobacteria (a-rhizobia) and Betaproteobacteria (b-rhizobia), but maybe also Gammaproteobacteria (c-rhizobia) (Shiraishi et al. 2010) , with about 180 species in 20 genera at the time of writing (Fig. 1). Among them, a-rhizobia are the most common group with a very wide distribution in biogeography and host plants, and beta-rhizobia are also well established with specific legumes though less widely distributed.It is common that symbiotic rhizobia are usually intermingled with nonsymbiotic bacteria at different taxonomic levels. For example, a group of nonsymbiotic bacteria isolated from maize root endosphere, Rhizobium
