['The bamboo Bambusa edulis has a long juvenile phase in situ, but can be induced to flower during in vitro tissue culture, providing a readily available source of material for studies on reproductive biology and flowering. In this report, in vitro-derived reproductive and vegetative materials of B. edulis were harvested and used to generate transcriptome databases by use of two sequencing platforms: Illumina and 454. Combination of the two datasets resulted in high transcriptome quality and increased length of the sequence reads. In plants, many MADS genes control flower development, and the ABCDE model has been developed to explain how the genes function together to create the different whorls within a flower.', 'As a case study, published floral development-related OsMADS proteins from rice were used to search the B. edulis transcriptome datasets, identifying 16 B. edulis MADS (BeMADS). The BeMADS gene expression levels were determined qRT-PCR and in situ hybridization. Most BeMADS genes were highly expressed in flowers, with the exception of BeMADS34. The expression patterns of these genes were most similar to the rice homologs, except BeMADS18 and BeMADS34, and were highly similar to the floral development ABCDE model in rice. Transient expression of MADS-GFP proteins showed that only BeMADS1 entered leaf nucleus. BeMADS18, BeMADS4, and BeMADS1 were located in the lemma nucleus. When co-transformed with BeMADS1, BeMADS15, 16, 13, 21, 6, and 7 translocated to nucleus in lemmas, indicating that BeMADS1 is a key factor for subcellular localization of other BeMADS.'] Is beMADS1 a key to delivery MADSs into nucleus in reproductive tissues-De novo characterization of Bambusa edulis transcriptome and study of MADS genes in bamboo floral development?
