DD: differential displayed fragment obtained by DDRT-PCR; Ug: previously assembled R. trigyna transcriptome unigene [8]; RPKM: reads per kilobase of exon model per million mapped reads in the whole transcriptome of R. trigyna; C-RPKM: transcript abundance in the control transcriptome; T-RPKM: transcript abundance in the salt-stressed transcriptome; “+”: salt-induced gene. Functional descriptions were obtained by aligning the 18 unigenes against the plant protein dataset of nr, Swiss-Prot/Uniprot protein database, Clusters of Orthologous Groups databases, Gene Ontology database, and Kyoto Encyclopedia of Genes and Genomes database, respectively [8].
