Abstract All living systems have stress tolerance mechanism with some modifications from bacteria to higher plants. Gene-expression is affected greatly by abiotic stress, where some Genes are up or down regulated. In the present work, identified three salinity tolerant Genes (one from each strain), were identified conferring the high salinity tolerance to bacteria and its expression levels go up by high salinity stress. These Genes are functional in tolerance to salinity stress of bacteria to adapt in their environments. The sequence from Bacillus marismortui and Shigella dysenteriae likes or similar to a sequence part of Ochrobactrum sp. bacteria. This sequence domain was responsible for periplasmic binding and sugar binding domain of LacI family protein. On the other hand, the sequence of Halomonas caseinilytica was matching to 5.8S ribosomal RNA in Fusarium sp. There is a cross-talk between the stresses and the resistance to that stress which confers or induces another tolerance to several other stresses. |
