Arachis hypogaea root transcriptome under rhizobial and nitrate treatments
This study investigates the transcriptional responses of Arachis hypogaea (peanut) roots during early nodulation signaling under contrasting nitrogen conditions. Root tissues were collected from plants subjected to four treatments: uninoculated control, rhizobial inoculation under low-nitrogen conditions, nitrate supplementation, and combined rhizobial inoculation with nitrate supplementation. Total RNA was extracted and sequenced using Illumina technology to generate stranded paired-end libraries. The dataset provides genome-wide expression profiles to identify genes and pathways involved in nodulation, nitrate signaling, and their regulatory interactions in peanut. These data will facilitate comparative analyses of legume-rhizobia symbiosis and nitrogen regulation in crop legumes.
