Gordonia sp.: a salt tolerant bacterial inoculant for growth promotion of pearl millet under saline soil conditions
In the resent study, a diazotrophic bacterial isolate JPA2 having the ability to tolerate salinity (6 % NaCl) and plant growth-promoting features was isolated from rhizospheric soil of weed Chenopodium murale growing in saline soil of Pindara (EC 11.47 dS m(−1)), district Jind (Haryana). The nitroge...

description | In the resent study, a diazotrophic bacterial isolate JPA2 having the ability to tolerate salinity (6 % NaCl) and plant growth-promoting features was isolated from rhizospheric soil of weed Chenopodium murale growing in saline soil of Pindara (EC 11.47 dS m(−1)), district Jind (Haryana). The nitrogen fixing ability of the isolate was confirmed by nifH gene amplification and acetylene reduction assay (38.9 nmol ethylene h(−1) mg(−1) protein). The potential of strain JPA2 to promote growth of pearl millet was investigated by inoculation experiment which showed significant increase in plant height (51.1, 39.9 and 28.8 %) and dry weight (55.9, 36.4 and 35.5 %) over uninoculated control plants at EC 0, 6, 8 dS m(−1), respectively. The strain JPA2 was Gram +ve and identified as Gordonia sp. on the basis of partial 16S rRNA gene sequencing and biochemical characterization. It is concluded that salt tolerant diazotrophic Gordonia sp. can be considered as a beneficial microbe for agriculture in saline soils. |
