### Plant Growth Promoting Assay  
The influence of inoculating _P. jordanii_ strain G34 on the germination and seedling growth of Tamaroi and Line 5004 genotypes under varying salinity levels was examined (Figure 2; Table 1). Salinity levels exceeding 80 mM led to a significant decrease in germination rates in both genotypes' inoculated seeds. Remarkably, Line 5004 (with _NAX2_) displayed significantly higher germination rates and root growth under elevated NaCl concentrations (>80 mM) compared to Tamaroi. Incremental salinity levels up to 200 mM NaCl resulted in reduced root numbers in both wheat genotypes. Figure 1: Cellular, colonial morphology, and biochemical tests of _P. jordanii_ strain G34. For non-saline conditions, both genotypes inoculated with _P. jordanii_ strain G34 exhibited substantial growth improvement, evidenced by increased root length and related traits (Table 1). Previous studies have documented the ability of _Pseudomonas_ spp. to promote plant growth through diverse mechanisms, including phytohormone production such as IAA and degradation by ACC deaminase activity, which aid in modulating plant stress responses [38]. Previous studies have shown that _Pseudomonas_ species, among others, play a crucial role in promoting plant growth under saline conditions by solubilizing phosphate, producing phytohormones, and reducing salt-stress damage [39; 40]. For example, _Pseudomonas_ spp. (Q6B) increased seed germination and promoted the seedling height of tomato plants, while other isolates such as Q1B enhanced the leaf number [41]. Additionally, _P. putida_ and _P. aeruginosa_ have been reported to mitigate salt-stress in wheat plants by lowering levels of ethylene levels in stressed plants [42]. These findings highlight the potential use of _Pseudomonas_ spp. to enhance plant growth in saline soils, making them effective biofertilizers for improving crop productivity and stress tolerance. Recent findings have further demonstrated significant positive effects on overall plant growth for both \begin{table}
