摘要

多种具有重要农业意义的微生物已被研究,它们在促进植物生长方面具有已知的潜力。窄养单胞菌是一种很有前途的植物增强剂、诱导剂和环境胁迫的保护剂。从向日葵根内球分离的S. indicatrix BOVIS40具有独特的特征,因为从南部非洲油籽作物分离的窄养单胞菌物种的基因组见解尚未报道。本研究对S. indicatrix BOVIS40进行了植物促生长筛选和基因组分析。基因组信息揭示了促进植物生长和抵抗环境胁迫的各种基因。S. indicatrix BOVIS40基因组中含有参与有机分子降解和生物转化的基因。此外,在菌株BOVIS40中还检测到其他参与生物膜生成、趋化性和鞭毛的基因,这些基因促进了细菌在根内球圈的定植,以及调节植物根发育和胁迫反应的植物激素基因。菌株的IAA活性可能是根形成的一个因素。对S. indicatrix BOVIS40生活方式的可测量方法可以在战略上为其作为生物接种剂在可持续发展环境友好型农业中的应用提供若干机会。本文的研究结果为进一步了解S. indicatrix BOVIS40的基因组功能奠定了基础,为进一步了解植物内圈微生物间的协同作用奠定了基础。综上所述,在温室试验中,强调了接种S. indicatrix BOVIS40的潜力,从而提出了其在促进植物和土壤健康方面的可持续应用。

Genomic assessment of Stenotrophomonas indicatrix for improved sunflower plant.

Diverse agriculturally important microbes have been studied with known potential in plant growth promotion. Providing several opportunities, Stenotrophomonas species are characterized as promising plant enhancers, inducers, and protectors against environmental stressors. The S. indicatrix BOVIS40 isolated from the sunflower root endosphere possessed unique features, as genome insights into the Stenotrophomonas species isolated from oilseed crops in Southern Africa have not been reported. Plant growth-promotion screening and genome analysis of S. indicatrix BOVIS40 were presented in this study. The genomic information reveals various genes underlining plant growth promotion and resistance to environmental stressors. The genome of S. indicatrix BOVIS40 harbors genes involved in the degradation and biotransformation of organic molecules. Also, other genes involved in biofilm production, chemotaxis, and flagellation that facilitate bacterial colonization in the root endosphere and phytohormone genes that modulate root development and stress response in plants were detected in strain BOVIS40. IAA activity of the bacterial strain may be a factor responsible for root formation. A measurable approach to the S. indicatrix BOVIS40 lifestyle can strategically provide several opportunities in their use as bioinoculants in developing environmentally friendly agriculture sustainably. The findings presented here provide insights into the genomic functions of S. indicatrix BOVIS40, which has set a foundation for future comparative studies for a better understanding of the synergism among microbes inhabiting plant endosphere. Hence, highlighting the potential of S. indicatrix BOVIS40 upon inoculation under greenhouse experiment, thus suggesting its application in enhancing plant and soil health sustainably.

期刊介绍: Current Genetics publishes genetic, genomic, molecular and systems-level analysis of eukaryotic and prokaryotic microorganisms and cell organelles. All articles are peer-reviewed. The journal welcomes submissions employing any type of research approach, be it analytical (aiming at a better understanding), applied (aiming at practical applications), synthetic or theoretical. Current Genetics no longer accepts manuscripts describing the genome sequence of mitochondria/chloroplast of a small number of species. Manuscripts covering sequence comparisons and analyses that include a large number of species will still be considered.
