De novo transcriptome assembly data for sengon (Falcataria moluccana) trees displaying resistance and susceptibility to boktor stem borers (Xystrocera festiva Pascoe).

OBJECTIVES: Sengon (Falcataria moluccana) is a popular tree species in community plantation forests in Java, Indonesia due to its fast-growing and multipurpose characteristics. However, without effective control measures sengon plantations are vulnerable to boktor stem borer (Xystrocera festiva) infestation. Previous research found some boktor-resistant trees amid mostly susceptible individuals. Resistant trees have higher levels of enzyme inhibitory activity than susceptible ones. However, efforts to differentiate between the two accessions using microsatellite markers failed to provide satisfactory answers. This dataset was created to study differences in gene expressions between resistant and susceptible accessions, and to identify candidate genes involved in boktor resistance in sengon. DATA DESCRIPTION: RNA was extracted from fresh wood samples collected from two individual trees: one heavily infested with boktor larvae, and the other showing no signs of infestation. The sample trees grow in close proximity to each other within the same plantation. The RNA was sequenced using the BGISEQ-500 platform and produced 78.5 million raw reads. De novo transcriptome were assembled using Trinity and produced 96,164 contigs after filtering and clustering. This transcriptome data is important for understanding pest resistance mechanisms in sengon trees, serving as basis for an improvement program for resistance to boktor pest.

De novo transcriptome datasets of Shorea balangeran leaves and basal stem in waterlogged and dry soil.

Shorea balangeran Burk locally known as balangeran has been widely used as recommended species for tropical peat swamp forest restoration, due to the capability of these species to grow in waterlogged and dry areas. However, the information concerning genetic basis of adaptation to ecological condition variation is limited and no transcriptome study has been reported in this context. Here we reported two sets of transcriptome data from a sample of leaf and basal stem that were taken from seedlings growing in potted media containing peat and mineral soil. The raw reads are stored in the DDBJ platform with accession number DRA008633.

The dataset of de novo transcriptome assembly of Falcataria moluccana cambium from gall-rust (Uromycladium falcatarium) infected and non-infected tree.

Sengon (Falcataria moluccana), formerly known as Albizia falcataria or Paraserianthes falcataria, is an essential tree species for the development of community-based timber plantation, especially in Indonesia. The plantations nowadays are facing a significant disease threat, namely infection of gall-rust fungi (Uromycladium falcatarium). However, a clear understanding of the molecular mechanisms of the tree response against the disease is still unknown. We carried out transcriptome assembly using BGISEQ-500 technology to provide assembled de novo transcriptome dataset generated from gall-rust infected and non-infected trees. The construction of assembled transcriptome was conducted using Trinity v.2.3.2 The raw reads are available in the DDBJ platform with accession number, DRA007983.

Metabolomics dataset of underutilized Indonesian fruits; rambai (Baccaurea motleyana), nangkadak (Artocarpus nangkadak), rambutan (Nephelium lappaceum) and Sidempuan salak (Salacca sumatrana) using GCMS and LCMS.

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; ß-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.
