Transcriptome dataset from Solanum lycopersicum L. cv. Micro-Tom; wild type and two mutants of INDOLE-ACETIC-ACID (SlIAA9) using long-reads sequencing oxford nanopore technologies.

ABSTRACT:

Objective

Tomatoes are the most widely consumed fruit vegetable and are relatively easy to cultivate. However, an increase in temperature causes some plants to respond with a decrease in fruit production. So, it is necessary to develop plants resistant to extreme temperature changes. The tomato cv. Micro-Tom has genetic variations in the gene of INDOLE-ACETIC-ACID, namely SlIAA9-3 and SlIAA9-5. However, the genetic information regarding the full-length transcript of the gene from this type of tomato plant is unknown. Therefore, this study aimed to determine the full-length transcript of the genes of these three types of tomatoes using long-reads sequencing technology from Oxford Nanopore.

Data description

The total RNA from three types of Micro-Tom was isolated with the RNeasy PowerPlant Kit. Then, the RNA sequencing process used PCR-cDNA Barcoding kit - SQK-PCB109 and continued with the processing of raw reads based on the protocol from microbepore protocol ( https://github.com/felixgrunberger/microbepore ). The resulting raw reads were 578 374, 409 905, and 851 948 for wildtype, iaa9-3, and iaa9-5, respectively. After obtaining cleaned reads, each sample was mapped to the tomato reference genome (S. lycopersicum ITAG4.0) with the Minimap2 program. In particular, 965 genes were expressed only in the iaa9-3 mutant, and 2332 genes were expressed only in the iaa9-5 mutant. Whereas in the wild type, 1536 genes are specifically expressed. In cluster analysis using the heatmap analysis, separate groups were obtained between the wild type and the two mutants. This proves an overall difference in transcript levels between the wild type and the mutants.
