MtSSP database release


MtSSPdb is available!

MtSSP database hosts large-scale genomics and transcriptomics data in M. truncatula and provides multiple functions to search, analyze and visualize various datasets. The aim of this database is to provide a detailed description of Small Secreted Peptides (SSPs) in M. truncatula, which were recently identified by our group. MtSSPdb includes a complete catalog of 70,094 M. truncatula genes with 2,455 SSP genes and 1,970 putative SSP genes predicted. Also, a peptide library with several synthetic peptides tested in different plant species is available.


The SSP Gene Expression Atlas in M. truncatula is part of the MtSSPdb, and hosts a rich RNA-seq data from diverse biological conditions, such as macronutrient deficiencies, nodule/root development, salt stress, symbiotic interactions, plant organs, and hormone treatments of 17 experiments represented by 200 conditions/treatments and 705 samples. SSP-GEA allows users to query for the expression levels of your genes of interest, analyze the expression, co-expression or perform GO and KEGG analyzes.
