Halophytes, a category of plants renowned for their ability to thrive in high soil salinity conditions, have garnered attention due to their resilience. However, a significant gap exists in our understanding of the endophytes associated with halophytes. This knowledge void coincides with a global call to explore eco-friendly compounds that can boost plant growth and act as alternatives to synthetic products. Recent studies have increasingly recognized plants as ‘biological factories’ with the ability to generate valuable and unique bioactive compounds. Despite this recognition, practical implementation faces a challenge in the slow growth rate of these plants. This impediment has prompted a closer examination of endophytes, microorganisms that symbiotically inhabit plants and algae. Interestingly, the exact understanding of the connection between endophytes and their host plants, including halophytes, is still unclear. Nonetheless, there is a commonly accepted belief that endophytes significantly contribute to the growth of plants. As a result, investigating endophytes originating from halophytes shows potential for providing significant advantages to the host plants. Notably, the fungi and bacteria that are affiliated with plants have been observed to have positive impacts, fostering growth and bolstering the overall well-being of the plants. Establishing internal bacterial or fungal populations within plants is a complex process, fraught with challenges that can impact the plant’s well-being. Despite these hurdles, recognizing and harnessing the potential of endophytes from halophytes may offer valuable insights and solutions for sustainable plant growth in salinity-stressed environments.
