Exploring the Interaction Dynamics of Growth-Promoting Bacterial Endophytes and Fertilizer on Oryza sativa L. Under Heat Stress.

ABSTRACT: The demand for rice (Oryza sativa L.) as a staple food continues to grow, but rising temperatures due to climate change pose a significant threat to its production. This study addresses the challenge by employing endophytic bacteria and fertilizer to mitigate the adverse effects of high temperatures on rice plants. Seedlings were evaluated for growth parameters, comparing outcomes with non-inoculated counterparts under normal and 40 to 45 °C heat shock conditions. Isolates underwent thorough DNA extraction and 16 S rRNA gene sequencing for identification and were scrutinized for their plant growth-promoting (PGP) traits. The effects of fertilizer and thermotolerant bacteria on rice plants were investigated in controlled chambers at 25 °C for 14 days, succeeded by exposure to 40 °C for 10 d
