Project description:This study sequenced the entire mitochondrial genome of Populus davidiana Dode. It was 779,361 bp in length, containing 33 protein-coding genes, 3 rRNA genes and 22 tRNA genes and 1 pseudogene, and its GC content was 44.8%. Phylogenetic analysis was conducted using 6 mitochondrial genomes from the Salicaceae and Euphorbiaceae families, resulting that P. davidiana Dode was closely related to Populus tremula and Populus tremula × Populus alba. These results will provide fundamental data for the evolutionary studies in Populus genus.

Project description:The genome of Populus davidiana, a keystone aspen species, has been sequenced to improve our understanding of the evolutionary and functional genomics of the Populus genus. The Hi-C scaffolding genome assembly resulted in a 408.1 Mb genome with 19 pseudochromosomes. The BUSCO assessment revealed that 98.3% of the genome matched the embryophytes dataset. A total of 31,862 protein-coding sequences were predicted, of which 31,619 were functionally annotated. The assembled genome was composed of 44.9% transposable elements. These findings provide new knowledge about the characteristics of the P. davidiana genome and will facilitate comparative genomics and evolutionary research on the genus Populus.

Project description:Prunus davidiana is a Chinese wild peach species belonging to the family Rosaceae. In this study, we first assembled the complete chloroplast (cp) genome of P. davidiana by Illumina paired-end reads data, then carried out phylogenetic analysis. The P. davidiana cp genome was 158,055 bp, containing a large single copy region (LSC) of 86,248 bp and a small single copy region (SSC) of 19,047 bp separated by a pair of inverted repeats (IRs) of 26,380 bp. The cp genome contained 131 genes, including 86 protein-coding genes, 37 transfer RNA (tRNA) genes and 8 ribosomal RNA (rRNA) genes. The result of the phylogenetic analysis showed that P. davidiana is closely related to P. mongolica.

Project description:BACKGROUND:Raw second-generation (2G) lignocellulosic biomass materials have the potential for development into a sustainable and renewable source of energy. Poplar is regarded as a promising 2G material (P. davidiana Dode×P. bolleana Lauch, P. bolleana, P. davidiana, P. euphratica, et al). However, their large-scale commercialization still faces many obstacles. For example, drought prevents sufficient irrigation or rainfall, which can reduce soil moisture and eventually destroy the chloroplast, the plant photosynthetic organelle. Heterosis is widely used in the production of drought-tolerant materials, such as the superior clone "Shanxinyang" selected from the offspring of Populus davidiana Dode×Populus bolleana Lauch. Because it produces good wood and is easily genetically transformed, "Shanxinyang" has become a promising material for use in tree genetics. It is also one of the most abundant biofuel plants in northern China. Understanding the genetic features of chloroplasts, the cp transcriptome and physiology is crucial to elucidating the chloroplast drought-response model. RESULTS:In this study, the whole genome of "Shanxinyang" was sequenced. The chloroplast genome was assembled, and chloroplast structure was analysed and compared with that of other popular plants. Chloroplast transcriptome analysis was performed under drought conditions. The total length of the "Shanxinyang" chloroplast genome was 156,190 bp, the GC content was 36.75%, and the genome was composed of four typical areas (LSC, IRa, IRb, and SSC). A total of 114 simple repeats were detected in the chloroplast genome of "Shanxinyang". In cp transcriptome analysis, we found 161 up-regulated and 157 down-regulated genes under drought, and 9 cpDEGs was randomly selected to conduct reverse transcription (RT)-qPCR., in which the Log2 (fold change) was significantly consistent with the qPCR results. The analysis of chloroplast transcription under drought provided clues for understanding chloroplast function under drought. The phylogenetic position of "Shanxinyang" within Populus was analysed by using the chloroplast genome sequences of 23 Populus plants, showing that "Shanxinyang" belongs to Sect. Populus and is sister to Populus davidiana. Further, mVISTA analysis showed that the variation in non-coding (regulatory) regions was greater than that in coding regions, which suggests that further attention should be paid to the chloroplast in order to obtain new evolutionary or functional insights related to aspects of plant biology. CONCLUSIONS:Our findings indicate that complex prokaryotic genome regulation occurs when processing transcripts under drought stress. The results not only offer clues for understanding the chloroplast genome and transcription features in woody plants but also serve as a basis for future molecular studies on poplar species.
