Comparative RNA-Seq Analysis Reveals the Organ-Specific Transcriptomic Response to Zinc Stress in Mulberry

Mulberry (Morus, Moraceae) is an important economic plant that considered zinc-rich. Zinc (Zn) a micronutrient plays vital roles in various bio-processes plants and animals. In the present study, comparative transcriptome analysis associated with physiological indicators was performed to reveal potential mechanism different organs response zinc toxicity mulberry. Physiological mulberry treated increasing concentrations of were monitored tolerance limits concentration. Transcriptome under excess stress spatial stress. The results show hormone signaling pathway secondary metabolism including lignin biosynthesis, flavonoid biosynthesis sugar are for treatment responses. addition, organ-based these pathways indicated. Lignin mainly responds lignified tissues or such as stems, main leaves, predominant roots. Further co-expression network indicated candidate genes involved response. Several transcription factors phenylpropanoid cell wall biogenesis further validated designed
