A transcriptomic analysis of superhybrid rice LYP9 and its parents Export

@article{citeulike:5220067, abstract = {10.1073/pnas.0902340106 By using a whole-genome oligonucleotide microarray, designed based on known and predicted rice genes, we investigated transcriptome profiles in developing leaves and panicles of superhybrid rice and its parental cultivars and . We detected 22,266 expressed genes out of 36,926 total genes set collectively from 7 tissues, including leaves at seedling and tillering stages, flag leaves at booting, heading, flowering, and filling stages, and panicles at filling stage. Clustering results showed that the F1 hybrid's expression profiles resembled those of its parental lines more than that which lies between the 2 parental lines. Out of the total gene set, 7,078 genes are shared by all sampled tissues and 3,926 genes (10.6\% of the total gene set) are differentially expressed genes (DG). As we divided DG into those between the parents (DG) and between the hybrid and its parents (DG), the comparative results showed that genes in the categories of energy metabolism and transport are enriched in DG rather than in DG. In addition, we correlated the concurrence of DG and yield-related quantitative trait loci, providing a potential group of heterosis-related genes.}, author = {Wei, Gang and Tao, Yong and Liu, Guozhen and Chen, Chen and Luo, Renyuan and Xia, Hongai and Gan, Qiang and Zeng, Haipan and Lu, Zhike and Han, Yuning and Li, Xiaobing and Song, Guisheng and Zhai, Hongli and Peng, Yonggang and Li, Dayong and Xu, Honglin and Wei, Xiaoli and Cao, Mengliang and Deng, Huafeng and Xin, Yeyun and Fu, Xiqin and Yuan, Longping and Yu, Jun and Zhu, Zhen and Zhu, Lihuang}, citeulike-article-id = {5220067}, citeulike-linkout-0 = {http://dx.doi.org/10.1073/pnas.0902340106}, citeulike-linkout-1 = {http://www.pnas.org/content/106/19/7695.abstract}, citeulike-linkout-2 = {http://www.pnas.org/content/106/19/7695.full.pdf}, citeulike-linkout-3 = {http://view.ncbi.nlm.nih.gov/pubmed/19372371}, citeulike-linkout-4 = {http://www.hubmed.org/display.cgi?uids=19372371}, day = {12}, doi = {10.1073/pnas.0902340106}, journal = {Proceedings of the National Academy of Sciences}, keywords = {and, are, categories, differentially, energy, enriched, expressed, genes, hybrid, in, metabolism, of, rice, super, the, transport}, month = {May}, number = {19}, pages = {7695--7701}, posted-at = {2009-07-21 19:05:10}, priority = {2}, title = {A transcriptomic analysis of superhybrid rice LYP9 and its parents}, url = {http://dx.doi.org/10.1073/pnas.0902340106}, volume = {106}, year = {2009} }
