| 1. | Compared to 042bm , the noea deletion mutant 042bma - km showed different degree of increase in nodule number , weight of nodule nodule and plant top dry weight on cultivars of putong zihua , baoding , ningxia , baifa and aohan , but decrease on milu . however , this mutant has no significant change in ability to nodulate cultivars of huanghou and zahua . hence , noea is involved in cultivar - specific nodulation
