Transcriptome sequence of mycorrhizal cotton

Identifying the key genes of cotton regulated by AMF inoculation under as stress. Arbuscular mycorrhizal fungi (AMF) have been proven to improve the arsenic (As) tolerance of host plants, and utilizing mycorrhizal plants to remediate As-contaminated soils is effective and feasible. However, comprehensive transcriptome analysis to reveal the molecular mechanism of arsenic tolerance in the symbiotic process of AMF and host plants is still limited. Transcriptomic analysis was performed for Gossypium seedlings with four treatments: non-inoculated Gossypium under non-As stress (CK0), non-inoculated Gossypium under As stress (CK100), F. mosseae-inoculated Gossypium under non-As stress (FM0), and F. mosseae-inoculated Gossypium under As stress (FM100). The project provided important insights into a molecular theoretical basis for the future improvement of As tolerance of mycorrhizal plants.
