We developed the iASPP, an integrative database of quantitative abiotic stress-responsive proteins (ASRPs) in, which contains 19,371 expression events of 6,214 ASRPs identified by low-throughput experiments (ASRPs_LTE) and 5,023,272 quantitative expression events of 511,937 ASRPs identified by high-throughput experiments (ASRPs_HTE) from 1,452 scientific literature and 602 datasets, involving 270 plant species and 213 abiotic stresses.

Currently, iASPP have three key features. First, it provides large-scale expression data of ASRPs at both transcription and protein levels. Second, it provides detailed experimental information collected from literature or datasets, including stress condition and quantitative method. Third, it provides comprehensive annotations for ASRPs by integrating multiple public databases.

PSPDB

PSPDB was the first protein-based plant stress database, which contains 2,064 manually curated plant stress proteins retrieved from UniProt, involving 134 plants and 30 stresses.

PlantPReS

PlantPReS was an open online proteomic database, which currently (as of October 2015) comprises > 20,413 entries from 456 manually curated articles, and contains > 10,600 unique stress responsive proteins.

STIFDB2

In addition to the extensive content in the first version, STIFDB2 is now updated with 15 stress signals, 31 transcription factors and 5,984 stress-responsive genes from three species (Arabidopsis thaliana, Oryza sativa subsp. japonica and Oryza sativa subsp. indica).

Stress2TF

Stress2TF currently documented 1533 regulatory relationships between 71 abiotic/biotic stresses and 558 TFs in 47 plant species. Each entry in Stress2TF contains detailed information about a stress-TF relationship such as plant name, stress name, TF and brief description of stress-TF relationship.
