Abstract:
CONCLUSIONS: In this review, we have discussed the untapped potential of orchid endophytic bacteria as a valuable reservoir of bioactive metabolites, offering significant contributions to plant growth promotion and disease protection in the context of sustainable agriculture. Orchidaceae is one of the broadest and most diverse flowering plant families on Earth. Although the relationship between orchids and fungi is well documented, bacterial endophytes have recently gained attention for their roles in host development, vigor, and as sources of novel bioactive compounds. These endophytes establish mutualistic relationships with orchids, influencing plant growth, mineral solubilization, nitrogen fixation, and protection from environmental stress and phytopathogens. Current research on orchid-associated bacterial endophytes is limited, presenting significant opportunities to discover new species or genetic variants that improve host fitness and stress tolerance. The potential for extracting bioactive compounds from these bacteria is considerable, and optimization strategies for their sustainable production could significantly enhance their commercial utility. This review discusses the methods used in isolating and identifying endophytic bacteria from orchids, their diversity and significance in promoting orchid growth, and the production of bioactive compounds, with an emphasis on their potential applications in sustainable agriculture and other sectors.

结论:在这篇综述中,我们已经讨论了兰花内生细菌作为生物活性代谢物的宝贵储库的未开发潜力,在可持续农业的背景下,为促进植物生长和疾病保护做出重大贡献。兰科是地球上最广泛和最多样化的开花植物家族之一。虽然兰花和真菌之间的关系是有据可查的,细菌内生菌最近因其在宿主发育中的作用而受到关注,活力,并作为新型生物活性化合物的来源。这些内生菌与兰花建立了相互关系,影响植物生长,矿物溶解,固氮,和保护免受环境压力和植物病原体。目前对兰花相关内生细菌的研究有限,为发现新物种或遗传变异提供了重要的机会,这些新物种或遗传变异可以改善宿主的适应性和胁迫耐受性。从这些细菌中提取生物活性化合物的潜力是相当大的,和可持续生产的优化策略可以显着提高其商业效用。这篇综述讨论了从兰花中分离和鉴定内生细菌的方法。它们的多样性和促进兰花生长的意义,以及生物活性化合物的生产,强调它们在可持续农业和其他部门的潜在应用。
