Pseudomonas fluorescens is an aerobic, gram-negative, ubiquitous organism present in agricultural soils and well adapted to grow in the rhizosphere. Aim: To study the effect of 1‐aminocyclopropane‐1‐carboxylic acid (ACC) deaminase from Pseudomonas fluorescens against saline stress under in vitro and field conditions in groundnut (Arachis hypogea) plants. Pseudomonas putida is an example for plant growth promoting Rhizobacterium, which produces iron chelating substances. They have the ability to induce a state of systemic resistance in plants, which provides protection against a broad spectrum of phytopathogenic organisms.

In this work, the metabolic elicitors extracted from the beneficial rhizobacterium Pseudomonas fluorescens N 21.4 were sequentially fragmented by vacuum liquid chromatography to isolate, purify and identify the compounds responsible for the extraordinary capacities of this strain to induce systemic resistance and to elicit secondary defensive metabolism in diverse plant species. Pseudomonas fluorescens is a widespread species which survive in soil and water with different chemical composition and different climatic conditions. Pseudomonas fluorescens produces a soluble, green fluorescent pigment pyoverdine which is responsible for chelating iron only when concentrations are low. Pseudomonas Fluorescens is no exception. Pseudomonas fluorescens, isolates from rhizosphere of winter rape, was antagonistic to pathogenic and saprophytic fungi on rape and flax and protected germinating plants against infections by Phoma lingam (Leptosphaeria maculans), F. acenaceam (Gibberella avanacea), respectively. Pseudomonas Fluorescens is an ecofriendly biological fungicide based on Pseudomonas Fluorescens highly active on root and stem rots, Sheath blights / leaf spots, mildews and other fungal diseases.
