Nod factor-treated Medicago truncatula roots and seeds show an increased number of nodules when inoculated with a limiting population of Sinorhizobium meliloti.

abstract：:Next-generation sequencing enables the study of species without a sequenced genome at the 'omics' level. Custom transcriptome databases are generated and global expression profiles can be compared. However, the assembly of transcriptome sequence reads into contigs remains a daunting task.
