Project description:Sorghum (Sorghum bicolor) is one of the world's most important cereal crops. S. propinquum is a perennial wild relative of S. bicolor with well-developed rhizomes. Functional genomics analysis of S. propinquum, especially with respect to molecular mechanisms related to rhizome growth and development, can contribute to the development of more sustainable grain, forage, and bioenergy cropping systems. In this study, we used a whole rice genome oligonucleotide microarray to obtain tissue-specific gene expression profiles of S. propinquum with special emphasis on rhizome development. A total of 548 tissue-enriched genes were detected, including 31 and 114 unique genes that were predominantly expressed in the rhizome tips (RT) and internodes (RI), respectively. Further GO analysis indicated that the functions of these tissue-enriched genes corresponded to their characteristic biological processes. A few distinct cis-elements, including ABA-responsive RY repeat CATGCA, sugar-repressive TTATCC, and GA-responsive TAACAA, were found to be prevalent in RT-enriched genes, implying an important role in rhizome growth and development. Comprehensive comparative analysis of these rhizome-enriched genes and rhizome-specific genes previously identified in S. propinquum indicated that phytohormones, including ABA, GA, and SA, are key regulators of gene expression during rhizome development. Co-localization of rhizome-enriched genes with rhizome-related QTLs in rice and sorghum generated functional candidates for future cloning of genes associated with rhizome growth and development. In conclusion, a whole rice genome oligonucleotide microarray was used to profile gene expression across five tissues of the perennial wild sorghum S. propinquum. Expression patterns of the five tissues were consistent with the different functions of each organ, and RT- and RI-enriched genes revealed clues regarding molecular mechanisms of rhizome development. Plant hormones, including ABA, GA, and SA, function as key regulators of rhizome gene expression and development. To shed further light on the identities of rhizome-specific genes, rhizome-enriched candidates were identified using QTL co-localization and comparative analysis.

To shed further light on the identities of rhizome-specific genes, rhizome-enriched candidates were identified using QTL co-localization and comparative analysis. In this study, the specific gene expression patterns across five tissues, including rhizome tip (RT, distal 1 cm of the young rhizome), rhizome internodes (RI), shoot tip (ST, distal 5 mm of the tiller after removing all leaves), shoot internodes (SI) and young leaf (YL) in Sorghum propinquum, especially in the rhizome, were characterized by using a rice genome array. Three independent biological replicates for each tissue from individual plants were performed. The reference was equivalent to a mix of the 5 tissues.

Project description:The Oryza longistaminata is a perennial wild rice species with AA genome, which characterized by the presence of rhizomatous stem. The rhizomatousness trait in rice was previously identified quantitatively controlled by many genes, but the molecular mechanism related to the rhizome initiation and elongation is still unknown. In this study, the specific gene expression patterns across five tissues in O. longistaminata, especially in the rhizome were characterized by using the Affymetrix rice microarray platform, the rhizome-specific expressed genes and its corresponding regulatory were further analyzed. The different gene sets were determined exclusively expressed in five tissues; strikingly 58 genes with functions related to transcription regulation and cell proliferation were identified as prevalent sets in rhizome tip, of them, several genes were functionally involved in tiller initiation and elongation. And a set of genes were differentially regulated in the rhizome tip relative to shoot tip, the predominant repressed genes are involved in photosynthesis, while genes related to phytohormone and the gene families with redundancy function were obviously differentially regulated. Several cis-regulatory elements, including CGACG, GCCCORE, GAGAC and a Myb Core, were highly enriched in rhizome tip or internode, and two cis-elements such as RY repeat and TAAAG, which implicated in the ABA signaling pathway, were found overrepresented in the rhizome tip in comparison with shoot tip. A few rhizome-specific expressed genes were co-localized on the rhizome-related QTLs regions, indicating these genes may be good functional candidates for the rhizome related gene cloning. The whole genome profiling of oryza longistaminata indicated that a very complex gene regulatory network underlies rhizome development and growth, and there might be an overlapping regulatory mechanism in the establishment of rhizome and tiller. Phytohormone such as IAA and GA are involved in the signaling pathway in determining rhizome. Several cis-elements enriched in rhizome and the identified rhizome-specific genes co-localized on the rhizome-related QTL intervals provide a base for further dissection of the molecular mechanism of rhizomatousness

Project description:Our study provides the first comprehensive insight into the comparative transcriptome between shoot and rhizome in sorghum propinquum. Using the deep RNA sequencing technique, more than 70% of genes were identified to be expressed. Comparative analysis revealed that a strong difference in gene expression patterns between shoot and rhizome organs, especially a set of organ-specific TF genes and cis-elements were determined, implying a unique complicated molecular network controlling shoot or rhizome growth and development. Furthermore, this data set including a deep coverage of the subterranean rhizome transcriptome, provided essential information for future molecular genetic dissection of rhizome formation.

Project description:We adopted the high-throughput sequencing technology and compared the transcriptomes of Moso bamboo rhizome buds in germination stage and late development stage. We found that the development of Moso bamboo rhizome lateral buds was coordinated by multiple pathways, including meristem development, sugar metabolism and phytohormone signaling. Phytohormones have fundamental impacts on the plant development. We found the evidence of several major hormones participating in the development of Moso bamboo rhizome lateral bud. Furthermore, we showed direct evidence that Gibberellic Acids (GA) signaling participated in the Moso bamboo stem elongation.
