Summary of "Pseudomonas citronellolis; a multi-metal resistant and potential plant growth promoter against arsenic (V) stress in chickpea."

Soil micro-biota plays a vital role in maintaining plant growth and fitness under normal and adverse conditions. Pseudomonas is one of the most important free-living and copious genera in south-west Punjab and involved in plant growth promotion under heavy metal stress. In this study, we have studied microbial diversity of the agricultural and marginal land based on 16S rRNA gene and screened eight strains of Pseudomonas for its tolerances towards various heavy metals and for plant growth promoting properties (PGP). The best strain is tested in chickpea plants against Arsenic (As) stress. All the strains responded differently to heavy metals viz. Arsenic, (As (0.3-0.5M) and As (250 μg mL) Cadmium (Cd) (250-350 μg mL), Chromium (Cr) (200-350 μg mL) and Mercury (Hg) (1-2 μg mL). Out of eight strains, only two strains (KM594398 and KM594397) showed plant growth promoting characters, concurrently they were highly tolerant to Arsenic (As). Pseudomonas citronellolis (PC) (KM594397) showed the best results in terms of As tolerance and plant growth promoting activity, hence further tested for actual plant growth response in chickpea (Cicer arietinum L.) under As (10-160 mg kg) stress. Pseudomonas citronellolis enhanced plant growth and dry biomass under As stress. High As tolerance and plant growth promoting activity of Pseudomonas citronellolis in chickpea especially designate this strain suitable for marginal lands and heavy metals contaminated sites.

Medical and Biotech [MESH] Definitions

A species of gram-negative, fluorescent, phytopathogenic bacteria in the genus PSEUDOMONAS. It is differentiated into approximately 50 pathovars with different plant pathogenicities and host specificities.

Viruses whose host is Pseudomonas. A frequently encountered Pseudomonas phage is BACTERIOPHAGE PHI 6.

Semisynthetic broad-spectrum cephalosporin with a tetrazolyl moiety that is resistant to beta-lactamase. It has been proposed especially against Pseudomonas infections.

Endogenous or exogenous substances which inhibit the normal growth of human and animal cells or micro-organisms, as distinguished from those affecting plant growth (= PLANT GROWTH REGULATORS).

A non-pathogenic species of Pseudomonas that occurs in soil, especially in the RHIZOSPHERE surrounding plant roots, as well as on the leaves of plants. It has anti-fungal and anti-nematode activities and is used in agriculture as a biocontrol agent.
