Review of genetic analysis and mechanisms of phosphate solubilization by phosphate solubilizing bacteria

Abstract EN

Phosphorous (P) is one of the most common etallic element in the earth's crust.

phosphorous is a component of important compounds, including nucleic acids, phospholipids, and ATP.

plants uptake only inorganic P as phosphate anions (HPO4 or H2PO4) from the soil.

phosphate solubilizing bacteria (PSB) are present in every ecological habitat ; these bacteria are more effective than fungi at phosphate solubilization in soil.

A variety of PSB has been isolated and identified from various ecological habitats.

numerous media have been utilized to screen and isolate PSB, such as pikovskaya's (PVK) agar / broth, bromophenol blue dye method, and national botanical research institute's phosphate growth medium (NBRIP).

PSB employs various mechanisms to make phosphorus available to orb by plants depending on the type of insoluble P source.

PSB promotes the growth and production of many crops by direct or indirect mechanisms.

the genetics of phosphate solubilization is studied to understand the mechanism of phosphate solubilization at the molecular level.

the genes involved in the solubilization of insoluble phosphate have been isolated and identified.

genetic engineering and gene manipulation are promising methods for developing PSB strains with improved phosphate solubilizing capacity.
