Screening of osmotic stress-tolerant bacteria for plant growth promotion in wheat (Triticum aestivum L.) and brinjal (Solanum melongena L.) under drought conditions

Abstract

Significance and Impact of the Study: Drought stress affects plant biomass and crop yield in arid and semiarid regions worldwide. The threat generated by drought stress must be addressed by improving plant growth under drought stress conditions. The application of osmotic stress-tolerant bacteria possessing plant growth-promoting properties is viable, eco-friendly and cost-effective. In this study, osmotic stress-tolerant bacteria improved the growth and biomass of wheat and brinjal under drought stress, and upregulated antioxidant enzymes. This study showed that microbes that mitigate drought stress may be used to enhance crop growth in arid and semiarid soils.

Enhancing Water Status and Nutrient Uptake in Drought-Stressed Lettuce Plants (Lactuca sativa L.) via Inoculation with Different Bacillus spp. Isolated from the Atacama Desert

“…In previous studies, some strains of this species have been reported to improve the drought tolerance in sugarcane, fenugreek, and wheat [ 26 , 27 , 28 ]. In addition, the strain ATMLC102021 was closely related to B. tequilensis clade; this species was described as osmotic stress-tolerant and presented with the capacity to improve drought stress tolerance in maize, wheat, and eggplant [ 29 , 30 ]. The strain ATMLC22021 was grouped within the clade of B. megaterium .…”

“…Поперше, її кількість не повинна негативно впливати на перебіг біохімічних реакцій і порушувати ключові ланцюги метаболізму. По-друге, сполука може бути переміщена в окремі компартменти як в межах клітини, так і між органами [2,18,21,26,30].…”

Identifying biotic stress-associated molecular markers in wheat using differential gene expression and machine learning techniques

“…For WRKY transcription factors, Patel P et al [39] mentioned in their study that WRKY transcription factors are thought to have a role in contributing to the level of thermotolerance. It was reported [39] that polyphenol oxidase (PPO) has a role in plant resistance to osmotic stress-tolerant bacteria.…”

“…For WRKY transcription factors, Patel P et al [39] mentioned in their study that WRKY transcription factors are thought to have a role in contributing to the level of thermotolerance. It was reported [39] that polyphenol oxidase (PPO) has a role in plant resistance to osmotic stress-tolerant bacteria. They found that bacterized seedlings showed a slight improvement in wheat roots and shoots, and the polyphenol oxidase was greater in the roots and shoots.…”
