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.

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.
