解析：本句的主语是“Genome wide underpinning”，可译为“基因组基础”；“of antagonistic and plant beneficial attributes of Bacillus sp. SBA12.”为后置定语，修饰“Genome wide underpinning”，可译为“拮抗和植物有益属性的芽孢杆菌 SBA12 的基因组基础”。 因此，本句可译为： 芽孢杆菌 SBA12 的拮抗和植物有益属性的基因组基础。
Genome wide underpinning of antagonistic and plant beneficial attributes of Bacillus sp. SBA12.

The plant beneficial microorganisms in rhizosphere are promising candidates to counter plant biotic and abiotic stresses. In the present study, Bacillus sp. SBA12 antagonistic to plant pathogenic fungi such as Phytophthora infestans and Sclerotinia sclerotiorum was explored. The complete genome of SBA12 comprises 5,297,566 bp size with GC content 49% and a total of 5698 genes. The genomic organization revealed presence of several biosynthetic clusters for antibiotics, siderophore and various other bioactive compounds such as lanthipeptide, LAP, bacteriocin, siderophore, NRP and terpenes. The gene cluster for fengycin known for its role as elicitors in inducing plant immunity is also reported. Besides this, lytic enzymes chitinases, β-glucanases and proteases involved in pathogen suppression, acid and alkaline phosphatases, deaminases responsible for the phosphate solubilization and release of ammonia are also reported. The genomic organization of SBA12 revealed several hallmarks for plant growth promotion and pathogen suppression activities.
根际有益微生物是应对植物生物和非生物胁迫的有前途的候选物。在本研究中，探索了对植物病原菌如致病疫霉和核盘菌具有拮抗作用的芽孢杆菌 SBA12。SBA12 的完整基因组大小为 5,297,566bp，GC 含量为 49%，共有 5698 个基因。基因组组织揭示了存在几种抗生素、铁载体和各种其他生物活性化合物的生物合成簇，如类杆菌、LAP、细菌素、铁载体、NRP 和萜类化合物。报告了已知作为诱导植物免疫的激发子的丰原素基因簇。除此之外，还报告了参与抑制病原体的裂解酶几丁质酶、β-葡聚糖酶和蛋白酶、酸性和碱性磷酸酶、负责磷酸溶解和氨释放的脱氨酶。SBA12 的基因组组织揭示了促进植物生长和抑制病原体的几个特征。
