Project description:miRNA expression profiling of Pinellia pedatisecta leaves comparing Pinellia ternata leaves in the same condition. Then we compared the accumulation of known miRNA families using microarray signals to identify further the differential miRNA expression between Pinellia pedatisecta and Pinellia ternata. Pinellia pedatisecta vs Pinellia ternata, independently grown and harvested. Each sample are mixed. One replicate per array.

Project description:We used wheat as rotational crop to assess the influence of continuous cropping on microbiome in Pinellia ternata rhizosphere and the remediation of rotational cropping to the impacted microbiota. Illumina high-throughput sequencing technology was utilized for this method to explore the rhizosphere microbial structure and diversity based on continuous and rotational cropping.
Project description:Pinellia ternata (Thunb.) Briet., a valuable herb native to China, is susceptible to the "sprout tumble" phenomenon due to high temperatures, resulting in a significant reduction in yield. The molecular regulatory mechanisms underlying the response of P. ternata to heat stress are not well understood. In this study, we integrated transcriptome and miRNAome sequencing to identify heat response genes, microRNAs (miRNAs), and key miRNA-target pairs in P. ternata under heat stress and room temperature conditions. Transcriptome analysis revealed extensive reprogramming of 4,960 genes across various categories, predominantly associated with cellular and metabolic processes, responses to stimuli, biological regulation, cell parts, organelles, membranes, catalytic and binding activity. miRNAome sequencing identified 1,597 known/conserved miRNAs that were differentially expressed in two test conditions. According to the analysis, genes and miRNAs associated with regulation of transcription, DNA-templated, transcription factor activity and sequence-specific DNA binding pathway, may play a major role in the resistance to heat stress in P. ternata. Integration of expression data of transcriptome and miRNAome determined high confidence 41 miRNA-mRNA pairs forming 25 modules. MYB-like protein and calcium-responsive transcription coactivator may play an integral role in the resistance to heat stress in P. ternata. In addition, the candidate genes and miRNAs were subjected to quantitative real-time PCR to evaluate their expression patterns. These results offer a foundation for future studies exploring the mechanism and critical genes of resistance to heat stress in P. ternata.
