Abiotic stress is one of the major constraints which restrain plant growth and productivity by disrupting physiological processes stifling defense mechanisms. Hence, present work aimed to evaluate sustainability bio-priming salt tolerant endophytes for improving tolerance. Paecilomyces lilacinus KUCC-244 Trichoderma hamatum Th-16 were obtained cultured on PDA medium containing different concentrations NaCl. The highest (500 mM) fungal colonies selected purified. at 61.3 × 10-6 conidia/ml about 64.9 10-3 colony forming unit (CFU) used priming wheat mung bean seeds. Twenty- days-old primed unprimed seedlings subjected NaCl treatments 100 200 mM. Results indicate that both sustain resistance in crops, however T. significantly increased (141 209%) chlorophyll content (81 189%), over control under extreme salinity. Moreover, reduced levels (22 58%) oxidative markers (H2O2 MDA) corresponded with antioxidant enzymes like superoxide dismutase (SOD) catalase (CAT) activities 110%). Photochemical attributes quantum yield (FV/FM) (14 32%) performance index (PI) (73 94%) also enhanced bio-primed plants comparison stress. In addition, energy loss (DIO/RC) was considerably less (31 46%), corresponding lower damage PS II level plants. Also, increase I P steps OJIP curve P. showed availability more active reaction centers (RC) Infrared thermographic images resistant it concluded use specifically can be an effective approach mitigate cosnequences develop a potential crop
