Sengon (Falcataria falcata) is an economically important legume tree widely cultivated in community forests, especially in Java Island. However, attacks of gall rust disease by Uromycladium falcatariae is difficult to manage. Understanding sengon genes expressions when artificially infected with gall rust fungi can help unravel its resistance mechanisms. Total RNA was extracted from sengon seedlings samples inoculated with U. falcatariae fungi at 7, 21, and 35 days after inoculation (DAI) and from the control group. Total RNA sequencing was performed using the PCR-cDNA Sequencing protocol (SQK-PCB109) from Oxford Nanopore Technologies. The RNA-Seq obtained varies from 1.3 million to 1.9 million total reads. The assembled full-length transcript was constructed using the RATTLE program, resulting in 21,819 transcripts. The TransDecoder program used to define open reading frames (ORFs) generated 2,342 transcripts, of which 34.15% were 5′prime_partial, 8.15% were 3′prime_partial, 8.5% were internal, and 49.14% were complete. Analysis of differentially expressed genes (DEGs) between resistant and susceptible seedlings, found that 1,013 genes that were up-regulated and 1,130 genes that were down-regulated in the resistant lines. The transcriptome data discussed in this article have been deposited in the DDBJ with accession number DRA015681.

The lime plant is a horticultural plant that grows in tropical regions. One of the cultivation maintenances to increase the production of lime fruits is pruning. However, the pruning technique of lime requires high production costs. In addition, phytohormones such as ethylene and abscisic acid have regulation to help drop leaves and branches. The study aimed to identify genes in lime involved in the self-pruning process during ethephon and abscisic acid treatments. Total RNA was extracted and subjected to long-read sequencing using a PCR-cDNA sequencing kit, Oxford Nanopore Technologies. The transcripts were produced 5,914 using the RATTLE program and ranged from 201 – 8,156 bp, and N50 was 1,292 bp. The RNA-seq dataset is available as a raw sequence read that scientists can further process and analyze, and this data can be helpful for lime breeding programs that can shed branches and leaves.

Myristica fatua is a tropical fruit tree species originating from Indonesia. Very few genomic resources are available for the species. We developed a full-length transcriptome assembly using long-read sequencing (MinION Nanopore technology) and produced 4.3 million reads (3.5 G of bases). The assembled full-length transcript was constructed using the RATTLE program and assembled 21,098 transcripts. The transcript ranged from 201 – 14,174 bp, and N50 was 2,017 bp. The transcripts were annotated with the UNIPROT database using BlastX. The functional annotation was performed using Blast2go software. The 8,445 microsatellite motif-containing contigs were identified. The raw reads are deposited in the ENA (European Nucleotide Archive) with ENA experiment accession number ERX6798613.

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).

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.
