Evolution and regulation of the Lotus japonicus LysM receptor gene family.

LysM receptor kinases were identified as receptors of acylated chitin (Nod factors) or chitin produced by plant-interacting microbes. Here, we present the identification and characterization of the LysM receptor kinase gene (Lys) family (17 members) in Lotus japonicus. Comprehensive phylogenetic analysis revealed a correlation between Lys gene structure and phylogeny.

Dissection of symbiosis and organ development by integrated transcriptome analysis of lotus japonicus mutant and wild-type plants.

Genetic analyses of plant symbiotic mutants has led to the identification of key genes involved in Rhizobium-legume communication as well as in development and function of nitrogen fixing root nodules. However, the impact of these genes in coordinating the transcriptional programs of nodule development has only been studied in limited and isolated studies. Here, we present an integrated genome-wide analysis of transcriptome landscapes in Lotus japonicus wild-type and symbiotic mutant plants.
