“…Transcripts of genes encoding CLV1-like RLKs occur throughout the plant, more specifically in the vasculature (Yamamoto, Karakaya & Knap 2000;Krusell et al 2002;Nishimura et al 2002a,b;Searle et al 2003;Schnabel et al 2005;Nontachaiyapoom et al 2007). Reciprocal grafting experiments between mutant and wild-type plants have shown that the hypernodulation phenotype is determined by the shoot genotype (Delves et al 1986;Francisco & Harper 1995;Krusell et al 2002;Men et al 2002;Nishimura et al 2002a,b;Penmetsa et al 2003). Hence, a receptor complex similar to the one that perceives CLV3 in the shoot apical meristem (SAM) of Arabidopsis and regulates stem cell homeostasis is active in legume shoots and controls the nodule number over long distances.…”

Restricted availability of nitrogen compounds in soils is often a major limiting factor for plant growth and productivity. Legumes circumvent this problem by establishing a symbiosis with soil-borne bacteria, called rhizobia that fix nitrogen for the plant. Nitrogen fixation and nutrient exchange take place in specialized root organs, the nodules, which are formed by a coordinated and controlled process that combines bacterial infection and organ formation. Because nodule formation and nitrogen fixation are energy-consuming processes, legumes develop the minimal number of nodules required to ensure optimal growth. To this end, several mechanisms have evolved that adapt nodule formation and nitrogen fixation to the plant's needs and environmental conditions, such as nitrate availability in the soil. In this review, we give an updated view on the mechanisms that control nodulation.

“…Therefore, SR are unique and promising experimental system for developmental studies, such as root formation, regeneration or nodulation in vitro (Tanaka et al, 2008;Jian et al, 2009). The application of FOX hunting to L. corniculatus would supplement existing techniques in mutagenesis and gene discovery in legumes, such as targeted EMS and fast neutron mutagenesis in soybean (Carroll et al, 1985;Men et al, 2002), L. japonicus (Wopereis et al, 2000;Hoffmann et al, 2007) and Medicago truncata (Penmetsa and Cook, 1997).…”

“…Mutants that had significantly high nodulating ability (supernodulating or hypernodulating) were generated through either EMS mutagenesis (Caroll et al, 1985;Gremaud and Harper, 1989) or through fast neutron irradiation (Men et al, 2002) (Table 3).…”

Efficient mutant production systems, through either physical or chemical mutagenesis, have been well established in soybean. A vast amount of genetic variability, of both quantitative and qualitative traits, has been generated through experimental mutagenesis in the past 30 years. Characterization of mutated traits has greatly advanced our understanding of the underlying mechanisms of a score of important traits, including the genetic and genomic basis of nodulation and synthesis of fatty acids and storage proteins. Mutation techniques have also been successfully used in breeding new soybean varieties. More than 100 mutant varieties were developed and released for commercial cultivation; among them are several groundbreaking varieties; i.e., the supernodulating variety Sakukei 4; the glycinin-rich variety Yumenori; the lipoxygenases-free variety Ichihime; and the low linolenic varieties IA3017 and IA2064. It is expected that more new varieties with novel traits will become available in the coming years, and a variety with a reduced phytate level may become available in the near future. Induced mutants will become a unique genetic resource in functional genomic studies, and the advance of functional genomics will increase the usefulness and use efficiency of induced mutations in soybean breeding.
