PGPR stands for Plant Growth Promoting Rhizobacteria. Royal PGPR is a combination of
nitrogen fixing inoculants, Phosphate solubilizing inoculants, bio control inoculants and
plant growth promoting inoculants. Plant growth-promoting rhizobacteria (PGPR)
are bacteria that live on plant roots and help plants grow. They can also help detoxify soil
polluted with heavy metals.
How PGPR help plants grow
a. Improve nutrient availability: PGPR help plants take up nutrients like nitrogen,
phosphorus, and potassium.
b. Produce phytohormones: PGPR produce hormones like auxins, abscisic acid,
ethylene, and cytokinins, which help plants cope with stress.
c. Regulate plant hormone levels: PGPR help regulate the levels of plant hormones.
d. Help plants withstand pathogens: PGPR help plants fight off pathogens.
e. Enhance metal tolerance: PGPR regulate genes that help plants tolerate metals.
How PGPR help detoxify soil
a. PGPR help detoxify soil polluted with heavy metals like lead, mercury, chromium, and
zinc.
b. PGPR help make heavy metals more bioavailable and mobile, so plants can accumulate
them.
c. PGPR help break down heavy metals through processes like chelation, solubilization, and
mineralization.
