"Dive into the world of tomato genomics with TomExpress, a game-changing platform that visualizes expression data, simplifies clustering, and reveals correlation networks."

The completion of the tomato genome sequence has ushered in a new era for plant research, positioning the tomato as a pivotal reference species within the Solanaceae family. This breakthrough has not only streamlined genetic and genomic investigations but also facilitated the use of high-throughput technologies, such as next-generation sequencing (NGS), to deepen our understanding of plant biology.

RNA sequencing (RNA-Seq) has emerged as a preferred method for studying global gene expression patterns, offering insights into the mechanisms driving plant development and responses to environmental cues. While technologies like microarrays and quantitative reverse-transcription PCR have been valuable, RNA-Seq provides a more comprehensive view of the transcriptome.

RNA-Seq’s ability to identify global RNA transcripts and quantify their abundance offers unparalleled opportunities. However, the diverse approaches to RNA-Seq data processing across different labs can introduce unintended inconsistencies. Addressing these challenges requires standardized tools and methods to ensure reliable and comparable results, paving the way for resources like TomExpress, which unifies the whole tomato expression data set.
