Description
Long non-coding RNAs (lncRNAs) have been realized to play an important role in several gene regulatory networks involved in various biological processes of plants stress response. However, systematic analysis of lncRNAs expressed in rice Cadmium (Cd) stress are limited. Thus, we presented the expression and characterization of lncRNAs in rice roots development at early stage in response to Cd stress.The lncRNA deep sequencing revealed differentially expressed lncRNAs between Cd stress and normal condition. In the Cd stress group, 69 lncRNAs were up regulated and 75 were down regulated. Otherwise, 386 matched lncRNA-mRNA pairs for 120 differentially expressed lncRNAs and 362 differentially expressed genes in cis were detected, and target gene-related pathway analysis showed significant changes in cysteine and methionine metabolism pathway related genes. For the trans, a total of 28,276 interaction relationships were detected between 144 lncRNAs and the differentially expressed protein-coding genes. The pathway analyses found that secondary metabolites such as phenylpropanoids and phenylalanine and photosynthesis pathways related genes were significantly altered by Cd stress. All these results indicate that lncRNAs may regulate genes of cysteine-rich peptides metabolism in cis and the secondary metabolites and photosynthesis in trans, then activated various physiological and biochemical reactions to response to excessive Cd. The present study provides a valuable resource for lncRNA studies in response to Cd treatment in rice. It expands our knowledge about lncRNA biology function as well as contributes to the annotation of the rice genome.
