Project description:Populus euphratica is a natural population grown in semirid areas. The molecular response of the poplar to drought maintain to be elucided, especially at global genome level. We used Affymetrix poplar genome genechip microarrays to analyze the full transcript expression underlying different drought intensities and identified significantly differently expressed genes during this process.

Project description:We present an efficient method to genome-wide discover new and drought stress responsive miRNAs in P. euphratica. High throughput sequencing of P. euphratica leaves found 197 conserved miRNAs between P. euphratica and Populus trichocarpa. Meanwhile, 189 new miRNAs which belonged to 120 families were identified, a large increasing to the number of P. euphratica miRNAs. Target prediction and degradome sequencing verification of 22 new and 21 conserved miRNA targets showed these targets were involved in multiple biological processes, including transcription regulation and response to stimulus. Furthermore, comparison of high-throughput sequencing with miRNA microarray profiling data indicated that 104 miRNA sequences were up-regulated, while 27 were down-regulated under drought stress. This preliminary characterization based on our findings provided a framework for future analysis of miRNA genes and their roles in key traits of poplar as stress resistance plant breeding and environment protection usage.

We used Affymetrix poplar genome genechip microarrays to analyze the full transcript expression underlying different drought intensities and identified significantly differently expressed genes during this process. Uniformly developed seedlings of P. euphratica grown in gradually long-term drought throught water-withholding treatment. Affymetrix poplar genechip was hired to investigate the full transcripts changed of the poplar response to different drought intensity levels.

Project description:Populus euphratica is a medium-sized deciduous tree naturally grown in high saline condition, however, the molecular response of the poplar to salinity at global genome level maintain to be elucidated. We used Affymetrix poplar genome microarrays to investigate the full transcript expression exposed to different salt intensities and identified significantly changed transcripts within the 24 hours after exposed to salt stress.

Project description:The desert plant Populus euphratica Oliv. has typical heterophylly; linear (Li), lanceolate (La), ovate (Ov) and broad-ovate (Bo) leaves grow in turn from young to adult trees. It is therefore a potential model organism for leaf development. To investigate the roles of RNAs (including mRNAs, miRNAs, lncRNAs and circRNAs) in the morphogenesis of P. euphratica heterophyll, the juvenile heterophyll were respectively sampled, and then their expression patterns were analyzed by small RNA sequencing and strand-specific RNA sequencing. We found that 1374 mRNAs, 19 miRNAs, 71 lncRNAs and 2 circRNAs were P. euphratica heterophyll morphogenesis associated (PHMA) RNAs, among them, 17 PHMA miRNAs could disturb the expression of 46 PHMA mRNAs, furthermore, 11 lncRNAs and 2 circRNAs interacted with 27 PHMA mRNAs by ceRNA hypothesis, respectively. According to GO and KEGG pathway analysis, PHMA RNAs were mainly involved in metabolic, response to stimulus and developmental processes. Our results indicated that both external environmental factors and genetic factors of P. euphratica co-regulated the expression of PHMA RNAs, caused the cell division was repressed, while cell growth was reinforced, and resulted in the morphogenesis of P. euphratica heterophyll, ultimately.
