Siderophore in Plant Nutritional
Management: Role of Endophytic
Bacteria
Gunjan Garg, Sandeep Kumar, and S. Bhati
Abstract Plants uptake nutrients specifically phosphorus, nitrogen, iron, and potassium with the help of beneficial bacteria in its available form. Bacteria helps in the
enhancement of plant growth via direct or indirect ways are considered as a Plant
Growth Promoting Rhizobacteria (PGPR). These are green alternatives to conserve
soil fertility sustainably by leveraging nutrition supports to plants in many ways.
Bacteria also produce siderophores and many phytohormones which support the
plant life in adverse stressful conditions. Recently, in this group of bacteria and
endophytic fungi many candidates are involved in the production of pyoverdine,
hydroxamate, ferrioxamines siderophores in rhizosphere region, which increases
three times Iron (Fe) transportation efficiency of root and shoot growth of the plants.
Siderophores reflect significant application in metal binding along with the iron and
ranked as “Fe-biosensors.” How siderophores production by bacteria facilitate bioremediation, weathering of soil-mineral particles that enhance the plant growth have
been reviewed in further.

14.1 Introduction
There is a demand for more yield and production of crops for the food security, while the production rate is adversely affected by different kinds of biotic
(insect/pest/fungus, etc.) and abiotic stresses (salt/water/temperature, etc.). Using the
biotechnological method, we can contrive transgenic stress tolerance plant, which
counterbalances the adverse effects of the environment. Endophytic microbiota plays
