Being one of the four main sesame-producing countries, China has contributed 15.2 to 32.5% of the total world sesame production over the past 10 years (2001 to 2010, UN Food and Agriculture Organization data). J Agirc Food Chem. The size of a haploid genome of S. indicum (2n = 26) was reported to be about 0.95 Gb, with a mass of 0.97 pg [63], which is out of proportion with the 0.51 Gb and 0.97 Gb of Cerathoteca sesamoides (2n = 32) and S. radiatum (2n = 64), respectively [64]. Plant Breed. 2011, 29: 644-652. 0. 1981, Rome, 157-163. Wei L-B, Zhang H-Y, Zheng Y-Z, Miao H-M, Zhang T-Z, Guo W-Z: A genetic linkage map construction for sesame (Sesamum indicum L.). The basic chromosome number in the Sesamum genus is X = 8 and 13, with X = 13 probably resulting from ancient polyploidy [37].

Economic Botany. 2006, 54: 9544-9550. Edited by: Amram A. Its small genome size favours the genomic analysis of key biological processes, such as oil synthesis and metabolism. In the second phase, Roche 454 paired-ends reads will be sequenced by December 2012, and the double-ended sequencing of the 40,000 BAC clones and full-length sequencing of 1,000 BAC clones will be completed by June 2013. malabaricum Nar. The present chromosome count of n = 28 in the species adds a … 2005, 124: 263-267. In most sexually reproducing organisms, somatic cells are diploid, containing two copies of each chromosome, while the sex cells are haploid, having one copy of each chromosome. (1ee7) Seed germination and dormancy. (1929) and later confirmed by many others. Results are summarized in three main categories: biological processes, cellular components and molecular functions. 2006, Boca Raton: CRC Press, 231-280. When male and female gametes fuse during fertilization, the number of chromosomes becomes equal to that in somatic cells. 10.1006/phrs.2002.0992. J Biochem. 2007, 3: 821-826. J Agric Food Chem. 2002, 45: 499-505. The regulation pathway related with the yellow leaf trait mutation in sesame was analyzed for the first time. Thongwittaya N. … As Sanger reads may contain vector sequences, the Lucy package was used to search and trim for cutting off the vector sequence contamination [78]. 1986, 50: 857-862. However, compared with other oilseed crops, sesame seed production is not consistent, as it is susceptible to pathogens, waterlogging and low temperature conditions [41]. The cytogenetic knowledge of the genus is very limited; thus, the chromosome numbers are known only for about one-third of the species. Kim MJ, Go YS, Lee SB, Kim YS, Shin JS, Min MK, Hwang I, Suh MC: Seed-expressed casein kinase I acts as a positive regulator of the SeFAD2 promoter via phosphorylation of the SebHLH transcription factor. Furthermore, we will construct a physical chromosome map based on at least 1,000 BAC clones using information obtained from BAC-FISH and BAC-end. 10.1038/nature10158. As mentioned previously, Sesamum latifolium has been suggested as the ancestor of sesame [2]. Cytogenetical work on Sesamum has been reviewed by Joshi (1961) and most of it is confined to investigation of species hybrids. The chromosome number of the cultivated acid composition (Suja et al., 2004). 10.1038/35048692. The above results indicate that the draft assembly has a high coverage of the coding region. We obtained functional annotations of all genes using InterProScan [87], which also determines motifs and domains. The results revealed the genetic character of yellow-green leaf color mutant Siyl-1. Chem Rev. 2 Segregation in several generations derived from the cross of Zhongzhi No.13 (P 1) with Det-4247 (P 2) revealed monogenic recessive inheritance pattern of determinacy Zhang et al. 2004, Göttingen: Cuvillier Press. Asian Agri-History. Sesame 1. Genetic Resources and Crop Evolution 57: 641-647. Sesame belongs to the Pedaliaceae family, which contains 60 species organised into 16 genera (Rendle, 1963; Ashri, 1998). J Agric Food Chem. Miller JR, Delcher AL, Koren S, Venter E, Walenz BP, Brownley A, Johnson J, Li K, Mobarry C, Sutton G: Aggressive assembly of pyrosequencing reads with mates.

Before … Bedigian reported that sesame was derived from the Indian subcontinent (the western Indian peninsula and parts of Pakistan) thousands of years ago, and believed that the progenitor of sesame is a taxon named S. orientale var. In order to determine the frequency and complexity of repetitive elements in the draft assembly, we compared the assembly information with the Arabidopsis repetitive elements database from the RepeatMasker library (version 20120418) and the sesame de novo database constructed for the Yuzhi 11 draft assembly (RepeatModeler, version 1.0.5) using RepeatMasker (version open-3.2.9) [75, 76]. Sesame (Sesamum indicum L.) is an ancient oil crop that has been referred to as the ‘Queen of oilseeds’ by the virtue of its high quality oil (Salako and Falusi, 2001). Bioinformatics. Yuzhi 11. Sierra Leone J Biomed Res. Thus, since the base chromosome number in the Sesamum genus is x = 8 and Sesame (/ ˈ s ɛ z ə m iː / or / ˈ s ɛ s ə m iː /; Sesamum indicum) is a flowering plant in the genus Sesamum, also called benne. However, the 13 chromosome pairs of sesame have not been characterised because of technological limitations and their small size. Bruce EA: Notes on African Pedaliaceae. The sesame chloroplast genome was published recently [59]. J Henan Agri Sci. Scientia Agricultura Sinica. It is recognized by various names like gingely, til, simsim, gergelim, biniseed, etc. Hsiao ESL, Lin LJ, Li FY, Wang MMC, Liao MY, Tzen JTC: Gene families encoding isoforms of two major sesame seed storage proteins, 11S globulin and 2S albumin. 2011, 10: 14264-14275. 2010, 58: 7693-7700. 10.1038/nbt.1883. Thirty-eight percent of the draft assembly was identified as repetitive elements (Table 3), only approximately 5.7% of which shared homology with the Arabidopsis database. Roche 454 paired-end reads and BAC-end reads are better for spanning longer repetitive elements and joining scaffolds into superscaffolds. I-007.9a E Rev.007. Nandi (1936) derived the basic number of … Article  In addition, sequencing of the sesame genome will facilitate studies of other genera of the Pedaliaceae family by providing a closely related reference genome. Wei L, Miao H, Zhang H: De novo transcriptome sequencing and analysis of sesame growth and development. After linkage analysis, 1184 bins (13,679 SNPs) were mapped onto 13 linkage groups (LGs), while the LG number was equal to the haploid chromosome number of Sesamum indicum L.. The genome coverage of both BAC libraries was 27- and 13-fold, respectively (H Zhang, unpublished data). 10.1271/bbb.100095. Chromosome number, precise number of chromosomes typical for a given species. S. indicum is the sole cultivar in the Sesamum genus and evolved from wild populations [14, 19]. We will use BAC-end information to retrieve and select 1,000 specific BAC clones, one end of which aligns well to the scaffold while the other end is located in a gap region, for full-length sequencing using the Illumina BAC polling method. Bedigian appeared in Hortus Indicus Malabaricus, Vol. Chromosome counts of Sesamum species All the 153 cells of the 63 analyzed individuals from the 9 accessions representing 4 wild Sesamum species had 2n = 32 chromosomes (Figure 2 and Table 2). Bioinformatics. Changes in chromosome number. 10.1093/bioinformatics/btn548. Thus, the number of sesame pseudochromosomes is fixed, which is important and helpful for comparative genomics and genetics studies such as … BMC Plant Biol. 2011, 27: 764-70.
