Sulfur is an essential element for biological molecules, with sulfate as the primary sulfur source plants. Under sulfate-deficiency, plants undergo physiological, metabolic, transcriptional, and post-transcriptional changes. Although Solanum lycopersicum (tomato) exhibits extensive transcriptome reprogramming during deficiency, role of microRNAs (miRNAs) in this response remains poorly explored. In study, we analyzed miRNAs expression tomato roots leaves at 3- 4-weeks post-sowing under...

Tomato (Solanum lycopersicum) is a globally important crop, yet the gene regulatory networks (GRNs) controlling expression remain poorly understood. In this study, we constructed GRNs for roots, leaves, flowers, fruits, and seeds by inferring transcription factor (TF)–target interactions from over 10,000 RNA-seq libraries using GENIE3 algorithm. We refined these with co-expression data computational predictions of TF binding sites. Our confirmed key regulators, including TOMATO AGAMOUS LIKE...

Abstract The increasing availability of omic data from non-model plant species has created a need for centralized, user-friendly platforms that maximize the utility these datasets. Here, we introduce PlantæViz, web-based tool designed integration, visualization, and analysis multi-omic across wide range species. PlantæViz offers advanced functionalities including gene co-expression regulatory networks, expression atlases, cistrome visualization metabolomics-transcriptomics providing robust...
