miRNA-seq analysis revealed a potential strategy underlying poplar root responses to low nitrogen stress.

Main Conclusion: 87 miRNAs responding to low nitrogen stress in poplar roots were identified by miRNA-seq, and their target genes were predicted. Additionally, several key miRNA-mRNA modules were summarized.

Asbtract: Nitrogen (N) is an essential nutrient for plants, and low nitrogen (LN) availability can constrain plant growth and development.

Integrating multiregulatory analysis reveals the negative regulatory function of miR482a in the response of poplar to canker pathogen infection.

Canker disease caused by the bacterium Lonsdalea populi is one of the most destructive diseases affecting poplar stems. However, the detailed stress response mechanisms of poplar have not been widely characterized. To explore the diverse regulatory RNA landscape and the function of key regulators in poplar subjected to L.
