Consequently, it results in affecting human population through entering into food chain. The current study aims that Cd stress (0.4 mM) led to toxicity and deleterious effects on 45-day-old Lycopersicon esculentum plants. The use of rhizobacterial strains underlines the main hypothesis of the present research that have been exploited in order to alleviate the Cd induced stress in plants and promoting their growth sidewise. The morphological parameters, plant pigments, and gaseous exchange parameters were estimated and found to be reduced in plants due to Cd toxicity. Along with this, the levels of phenolic compounds and osmoprotectants were stimulated in plants raised in Cd spiked soils. In addition, free amino acid content was reduced in plants under Cd treatment. It was revealed that these bacterial strains Pseudomonas aeruginosa (M1) and Burkholderia gladioli (M2) when inoculated to tomato plants improved the morphological characteristics and enhanced photosynthetic attributes. Moreover, the level of phenolic compounds and osmoprotectants were further enhanced by both the inoculating agents independently. However, in situ localization studies of phenol accumulation in root sections was found to be enhanced in Cd treated plants as revealed through higher intensity of yellowish-brown colour. The supplementation of bacterial strains further accumulated the phenols in Cd stressed root sections as evidenced through increased colour intensity. Therefore, the present study suggested that bacterial strains mitigates Cd stress from tomato plants through improving morphological, physiological and metabolite profiles. Consequently, the present research advocates the best utilization of rhizobacteria as stress alleviators for sustainable agriculture.<\/jats:p>","DOI":"10.3390\/biom9100581","type":"journal-article","created":{"date-parts":[[2019,10,8]],"date-time":"2019-10-08T09:00:38Z","timestamp":1570525238000},"page":"581","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Microbial Fortification Improved Photosynthetic Efficiency and Secondary Metabolism in Lycopersicon esculentum Plants Under Cd Stress"],"prefix":"10.3390","volume":"9","author":[{"given":"Kanika","family":"Khanna","sequence":"first","affiliation":[{"name":"Department of Botanical and Environmental Sciences, Guru Nanak Dev University, Amritsar 143005, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sukhmeen Kaur","family":"Kohli","sequence":"additional","affiliation":[{"name":"Department of Botanical and Environmental Sciences, Guru Nanak Dev University, Amritsar 143005, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Puja","family":"Ohri","sequence":"additional","affiliation":[{"name":"Department of Zoology, Guru Nanak Dev University, Amritsar 143005, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renu","family":"Bhardwaj","sequence":"additional","affiliation":[{"name":"Department of Botanical and Environmental Sciences, Guru Nanak Dev University, Amritsar 143005, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asma A.","family":"Al-Huqail","sequence":"additional","affiliation":[{"name":"Department of Botany and Microbiology, King Saud University, Riyadh 11451, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manzer H.","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"Department of Botany and Microbiology, King Saud University, Riyadh 11451, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ghada Saleh","family":"Alosaimi","sequence":"additional","affiliation":[{"name":"Department of Botany and Microbiology, King Saud University, Riyadh 11451, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2734-4180","authenticated-orcid":false,"given":"Parvaiz","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Botany and Microbiology, King Saud University, Riyadh 11451, Saudi Arabia"},{"name":"Department of Botany, S.P.
