abstract = {Miscanthus lutarioriparius is a promising lignocellulosic
feedstock for second-generation bioethanol production.
However, the genomic resource for this species is relatively
limited thus hampers our understanding of the molecular
mechanisms underlying many important biological processes.
In this study, we performed the first de novo transcriptome
analysis of five tissues (leaf, stem, root, lateral bud and
rhizome bud) of M. lutarioriparius with an emphasis to
identify putative genes involved in rhizome development.
Approximately 66 gigabase (GB) paired-end clean reads were
obtained and assembled into 169,064 unigenes with an average
length of 759 bp. Among these unigenes, 103,899 $(61.5\%)$
were annotated in seven public protein databases.
Differential gene expression profiling analysis revealed
that 4,609, 3,188, 1,679, 1,218, and 1,077 genes were
predominantly expressed in root, leaf, stem, lateral bud,
and rhizome bud, respectively. Their expression patterns
were further classified into 12 distinct clusters. Pathway
enrichment analysis revealed that genes predominantly
expressed in rhizome bud were mainly involved in primary
metabolism and hormone signaling and transduction pathways.
Noteworthy, 19 transcription factors (TFs) and 16 hormone
signaling pathway-related genes were identified to be
predominantly expressed in rhizome bud compared with the
other tissues, suggesting putative roles in rhizome
formation and development. In addition, a predictive
regulatory network was constructed between four TFs and six
auxin and abscisic acid (ABA) -related genes. Furthermore,
the expression of 24 rhizome-specific genes was further
validated by quantitative real-time RT-PCR (qRT-PCR)
analysis. Taken together, this study provide a global
portrait of gene expression across five different tissues
and reveal preliminary insights into rhizome growth and
development. The data presented will contribute to our
understanding of the molecular mechanisms underlying rhizome
development in M. lutarioriparius and remarkably enrich the
genomic resources of Miscanthus.},
