Abstract. Natawijaya A, Ardie SW, Syukur M, Maskromo I, Hartana A, Sudarsono S. 2019. Genetic structure and diversity between and within African and American oil palm species based on microsatellite markers. Biodiversitas 20: 1233-1240. The genus Elaeis consists of only two species, Elaeis guineensis Jacq. (the African oil palm species) and E. oleifera (HBK) Cortes (the American oil palm species). E. guineensis (E.g) is widely cultivated in southeast Asia and Africa, whereas E. oleifera (E.o) is naturally existed and cultivated in Central and South America. The objectives of this research were to analyze genetic diversity of eight groups of E.g and two groups of E.o using co-dominant genetic markers (SSRs) and evaluate their genetic structures. A total of 27 SSR loci was used to genotype a total of 128 accessions of African oil palm species (E.g) belonging to three different types (Dura, Pisifera and Tenera) and eight genetic backgrounds (Dumpy Dura and Deli Dura; Avros, Dumpy Avros, Binga, and Angola Pisifera; and Angola and Dumpy Avros Tenera) and 64 accessions of E.o collected from two different regions (Tefe and Manaus). The genotype data were used to calculate the population genetic diversity and structures for each oil palm species using the appropriate software. Results of the analysis indicated although they belonged to two different species, E.g and E.o shared many of the same SSR alleles in their genome and only contain few species-specific SSR alleles. Most of the evaluated genetic parameters were similar between E.g and E.o oil palm species but E.o has higher average number of effective allele than that of E.g. The calculated genetic variance is mostly belonged to the within-species variance source while the between species is relatively small. The phylogenetic tree and structure analysis reveal the high genetic variability among the evaluated oil palm groups which would be beneficial for future breeding program at Mekarsari Research Station. The tested E.o specific alleles were effective for identifying introgression lines between Eo × E.g // E.g carrying the E.o chromosome fragments. Therefore, these E.o specific alleles could be used in oil palm backcrossing program to monitor the introgression process.
The information of secondary metabolite compound from underutilized Indonesian fruits are still limited including rambai ( Baccaurea motleyana Müll.Arg.), nangkadak ( Artocarpus nangkadak or A. heterophyllus x A. integer ), rambutan ( Nephelium lappaceum L.) and Sidempuan salak ( Salacca sumatrana Becc.). To identify the secondary metabolite, we used GC-MS (gas chromatography-mass spectrometry) and LC-MS (liquid chromatography-mass spectrometry) analyses. The accessions/varieties numbers used in this analysis including two accession for rambai, three accessions for nangkadak, four varieties for rambutan and three accessions for Sidempuan salak. All sample were collected from edible part such arilode/carpel and also rind for only rambutan. Based on, spectral data showed common and specific secondary metabolite compounds in each commodity. Preliminary GCMS analysis from the dataset obtained specific secondary metabolites contained in rambai; Decanoic acid, 1-Decene, Methyl salicylate and Stearyl alcohol, nangkadak; β-Cyclocitral, 2-Furanmethanol and Linoleic acid, rambutan; Citraconic anhydride, 3,5-Dideuteropyridine-4-carboxylic acid, Isobutyl formate and n-Methyl-D3-Aziridine, and Sidempuan salak; 5-Formyl-2-furfurylmethanoate, 2-Methoxy-4-vinylphenol and Tiglic acid.
Baccaurea motleyana Müll. Arg. (rambai) is one of the underutilized fruit natives to Indonesia, Thailand, and Malaya Peninsula and it is mostly cultivated in Java island (Lim, 2012) [1]. The edible part of fruits is white and reddish arillodes in which having sweet to acid-sweet tastes. However, nucleotide as well as transcriptome information of this species is still scarce, no information has been deposited in GenBank. In this data article, we performed for the first time of de novo assembly of transcriptome using paired-end Illumina technology. The assembled contigs were constructed using Trinity and after filtering and clustering, produced 37,077 contigs. The contig ranged 201–4972 bp and N50 has 696 bp. The contig was annotated with several database such as SwissProt, TrEMBL, nr and nt NCBI databases. The raw reads were deposited in DDBJ with DRA numbers, DRA007358. The assembled contigs of transcriptome are deposited in the DDBJ TSA with accession number, IADP01000001–IADP01037077 and also can be accessed at http://rujakbase.id.
Nephelium lappaceum (Rambutan), is one of tropical fruit in which - cultivated widely in Indonesia and has good taste and aroma. However, the transcriptomic study of rambutan has limited. In this study, we performed transcriptome assembly using paired-end Illumina technology. The assembled transcriptome was constructed using Trinity and after filtering and removal sequences redundancy produced 36,303 contigs. The contig ranged 201–11,770 bp and N50 has 1327 bp. The contig was annotated with several databases such as SwissProt, TrEMBL, and nr/nt of NCBI databases. The raw reads are deposited in the DDBJ with DRA accession number, DRA007359: https://www.ncbi.nlm.nih.gov/sra/?term=DRA007359. The assembled contigs of transcriptome are deposited in the DDBJ TSA repository with accession number IADQ01000001–IADQ01036303: ftp://ftp.ddbj.nig.ac.jp/ddbj_database/tsa/IADQ.gz and also can be accessed at http://rujakbase.id.
Indonesia has a high genetic diversity of tropical fruits. However, studies on genomics are still very limited. In this data article, six underutilized Indonesian fruits were analyzed for the estimated genome size and partial data of genome assembly including Artocarpus nangkadak (Artocarpus heterophyllus x Artocarpus integer), Salacca sumatrana, Flacourtia inermis, Lansium domesticum, Pometia pinnata, and Syzygium samarangense. These genome data may be used to construct molecular markers for plant systematics and breeding program of these species. Our genome data were sequenced paired-end libraries using BGISeq-500 and generated approximately 5 Gb of bases per species. The raw sequences have been deposited in the DNA Data Bank of Japan (DDBJ) under the DDBJ BioProject umbrella with accession number PRJDB7265 and to the DDBJ Read Archive for each species following Artocarpus nangkadak (DRA007398), Salacca sumatrana (DRA007394), Flacourtia inermis (DRA007395), Lansium domesticum (DRA007393), Pometia pinnata (DRA007396), Syzygium samarangense (DRA007397).
