bring out important data as well as comparing attempts, opening the method

for the modeling of the processes concerned.

There are public internet-based information hubs and platforms which

are available devoted to plant’s reactions to stress. They are important for

organizing results and other relevant data from diverse levels of research

studies and making it available to all members of the scientific community

who are interested.

At the genomic level, some databases are available dedicated to plant

response to diverse stress. Plant stress (https://plantstress.com/) is a public

internet-based information facility, a consultancy service, as well as a plat­

form for an expert update on relevant topics in plant environmental abiotic

stress. Plant Stress Gene Database (http://ccbb.jnu.ac.in/stressgenes/) is

another resource of Plant Stress Gene Database which contains 259 stress-

associated genes from 11 species, as well as the entire accessible data on

each gene. The database even contains orthologs and paralogs of proteins

encoding stress-related genes.

Globally drought is one of the most significant abiotic stressors. Plants

have a variety of physiological and molecular drought escaping and

drought tolerance strategies to deal with reduced water supply. Several

drought stress-related genes determine transcription factors that influence

the expression of other genes concerned with a variety of physiological as

well as molecular responses under drought stress. DroughtDB (https://pgsb.

helmholtz-muenchen.de/droughtdb/) is a database that contains curated

genes implicated in drought stress response, as well as extensive information

on calculated ortholog genes in nine model and crop plants (Alter et al.,

2015). PASmiR (https://tools4mirs.org/software/mirna_databases/pasmir/)

is a resource on miRNA molecular control for plant abiotic stress based on

over 200 existing literature, resulting in 1,038 regulatory connections among

682 miRNAs as well as 35 distinct forms on abiotic stressors in 33 different

plant species. The search engine permits users to search for miRNAs by

name, species, or kind of abiotic stress (Zhang et al., 2013).

At the proteomic level, some databases are available dedicated to plant

response to diverse stress. The plant stress protein database (PSPDB) (http://

bioclues.org/pspdb/) is a general resource at the protein level that includes

2,064 carefully edited plant stress proteins representing 134 plant species,

having functions across 30 distinct types both biotic and abiotic stressors

highlighted. One can get information through gene, species, keyword, cita­

tion, gene families, as well as taxonomic categorization from the database.

PlantPReS (www.proteome.ir) is another resource of proteomics on plant’s
