Genome-wide analysis of long non-coding RNAs (lncRNAs) in two contrasting soybean genotypes subjected to phosphate starvation

Abstract Background Phosphorus (P) is essential for plant growth and development, low-phosphorus (LP) stress a major factor limiting the yield of soybean. Long noncoding RNAs (lncRNAs) have recently been reported to be key regulators in responses plants conditions, but mechanism through which LP mediates biogenesis lncRNAs soybean remains unclear. Results In this study, explore response mechanisms stress, we used roots two representative genotypes that present opposite P deficiency, namely, P-sensitive genotype (Bogao) P-tolerant (NN94156), construction RNA sequencing (RNA-seq) libraries. total, 4,166 novel lncRNAs, including 525 differentially expressed (DE) were identified from at different levels. GO KEGG analyses indicated numerous DE might involved diverse biological processes related phosphate, such as lipid metabolic processes, catalytic activity, cell membrane formation, signal transduction, nitrogen fixation. Moreover, lncRNA-mRNA-miRNA lncRNA-mRNA networks constructed, results several promising highly valuable further analysis underlying stress. Conclusions These revealed can significantly alter genome-wide profiles particularly those Bogao. Our findings increase understanding provide new insights into function
