В статье приведены аналитические данные по опубликованным в последние годы в современных научных источниках сведениям о механизмах, по которым эндофитные бактерии галофитных растений могут развиваться под влиянием засоления растений. Галотолерантные бактерии способны расти в средах с широким диапазоном солености, от 1 до 33 % NaCl, а также в отсутствие NaCl. Поэтому они хорошо подходят для выращивания в ризосфере галофитов, где часто бывает низкий водный потенциал из-за солевого стресса в сухом климате. Интересно, что PGPR и эндофитные бактерии, выделенные из экстремальных условий окружающей среды, сохраняют свои черты стимуляции роста растений. Согласно анализу к этим механизмам относятся продукция АЦК-дезаминазы, продукция фитогормонов, продукция нерастворимых фосфатов, продукция сидерофоров, фиксация азота, повышение уровня антиоксидантов, накопление совместимых растворенных веществ, производство экзополисахаридов, производство галоцинов и биологический контроль фитопатогенов. Проанализированные данные показывают, что эндофитные бактерии в будущем могут быть использованы при возделывании сельскохозяйственных культур на засоленных территориях и служат основой для проведения исследований в этом направлении в больших масштабах.
The article presents analytical data on the information published in recent years in modern scientific sources on the mechanisms by which endophytic bacteria of halophytic plants can develop under the influence of plant salinity. Halotolerant bacteria are able to grow in media with a wide range of salinity, from 1 to 33 % NaCl, as well as in the absence of NaCl. Therefore, they are well suited for cultivation in the halophyte rhizosphere, where there is often low water potential due to salt stress in dry climates. Interestingly, PGPR and endophytic bacteria isolated from extreme environmental conditions retain their plant growth promoting traits. According to the analysis, these mechanisms include ACC deaminase production, phytohormone production, insoluble phosphate production, siderophore production, nitrogen fixation, increased antioxidant levels, and accumulation of compatible solutes. , production of exopolysaccharides, production of halocins, and biological control of phytopathogens. The analyzed data show that endophytic bacteria in the future can be used in the cultivation of agricultural crops in saline areas and serve as the basis for conducting research in this direction on a large scale.
