Welcome to PbtRF Database

A tRNA-Derived Fragments Database For Biotic Conditions

PbtRF Database constitutes a specialized repository for plant stress responses, meticulously curating over 600,000 transfer RNA-derived fragments (tRFs) identified across a phylogenetically diverse range of plant species. This comprehensive resource originates from a research initiative that examined extensive datasets encompassing these tRFs from prominent model organisms: Arabidopsis thaliana, Oryza sativa, and Solanum lycopersicum. The database serves as a valuable platform for researchers investigating the multifaceted roles of tRFs in plant responses to biotic stress, facilitating the exploration of these crucial regulators and their potential as stress biomarkers.
