Project description:Two ramie cultivars, Zhongzhu no 2(Z2) and Huazhu no 4 (H4), showed constructing adventitious root formation (ARF) rate. Comparative transcriptome analysis was performed to study gene expression profiles in Z2 and H4 ramie during adventitious root formation. Illumina sequencing yielded a total of 92,794,556,688 bases data, and about 301.47 M and 313.06 M raw reads for Z2 and H4 plants, respectively. After quality control, every library obtained over 43 million reads, which is enough for the quantitative analysis of gene expression. Using Trinity software, these clean reads were first assembled into 121,492 transcripts, finally into 66,881 unigenes with an average length of 1144.25 bp. About 148.74 M and 138.72 M clean reads of H4 and Z2 were mapped to reference genes via Bowtie, respectively. The ratio of mapped clean reads for eight libraries ranged from 74.47% to 75.38% (average: 74.8%). By comparing gene expression levels in Tm and CK ramie stems, we identified 772 DEGs in H4 plants during RPF, including 7220 up-regulated and 8154 down-regulated DEGs. We identified 1256 DEGs in Z2 plants during RPF, which included 779 up-regulated and 447 down-regulated DEGs. We also identified 1919 DEGs between Z2 and H4 plants. There were 1147 (731 up-regulate and 416 down-regulated) DEGs uniquely in Z2, and 603 (202 up-regulate and 461 down-regulated) DEGs uniquely in H4 plants. The two genotypes shared 109 DEGs, which indicates some common pathways during ARF.
Project description:This project is a proteomic comparison of Hyphomicrobium sp. MC8b grown with dichloromethane or with methanol. The datasets were obtained using the annotated genome of Hyphomicrobium sp. MC8b.
