Endophytes from Halotolerant Plants Aimed to Overcome Salinity and Draught
The aim of our research was to study the endosphere of four halophytic plants: <i>Salicornia europaea</i> L., <i>Salsola australis</i> (R.Br.), <i>Bassia sedoides</i> (Pall.) and <i>Kochia prostrata</i> (L.) Schrad. from arid and saline areas of the St...

| description | The aim of our research was to study the endosphere of four halophytic plants: <i>Salicornia europaea</i> L., <i>Salsola australis</i> (R.Br.), <i>Bassia sedoides</i> (Pall.) and <i>Kochia prostrata</i> (L.) Schrad. from arid and saline areas of the Stavropol Territory, Russia. In total, 28 endophyte strains were isolated from the roots and stems of these halophytic plants. Most of the isolates (23 out of 28) were identified as <i>Bacillus</i> sp. while others belonged to the genera <i>Oceanobacillus, Paenibacillus, Pantoea, Alcaligenes</i> and <i>Myroides</i>. Three strains of <i>Bacillus</i> sp. (Se5R, Se1-1R, and Se1-3S), isolated from the <i>S. europaea</i> were capable of growth at 55 °C and in 10% of NaCl. Strains Se1-4S, Kp20-2S, and Bs11-2S <i>Bacillus</i> sp. (isolated from the <i>S. australis</i>, <i>K. prostrata</i> and <i>B. sedoides,</i> respectively) demonstrated strong plant growth promoting activity: 85–265% over control lettuce plants and a high degree of growth suppression (59.1–81.2%) of pathogenic fungi <i>Fusarium oxysporum</i>, <i>Bipolaris sorokiniana</i> and <i>Rhizoctonia solani</i>. Selected strains can be promising candidates for the development of bioinoculants to facilitate salt soil phytoremediation and be beneficial for mitigating the salt stress to the plants growing in salt-affected habitats. |
