摘要:
为了探讨从大庆盐碱土壤中分离的卓贝尔氏菌(Zobellella sp.DQSA1)的耐盐碱能力及其在盐碱胁迫下对拟南芥的促生作用,采用全基因组测序技术对卓贝尔氏菌DQSA1基因进行基因组测序和功能注释,分析其基因组结构和功能基因,之后测定DQSA1在不同pH值、NaCl浓度条件下的生长情况,并评估其对拟南芥生长的影响。测序结果表明,DQSA1的基因组为环状结构,大小为 4 201 419 bp,GC含量为61.14%,共编码3 801个基因。基因组功能注释结果揭示了与氨基酸代谢、碳水化合物代谢、膜转运和信号转导相关的基因,这些基因可能在耐盐碱方面发挥重要作用。通过试验发现,DQSA1在pH值为8~12、NaCl浓度为1%~3%的条件下生长状态最佳,表现出较强的耐盐碱性能。在盐碱胁迫条件下,DQSA1显著提高了拟南芥的根长、鲜重,拟南芥的根长和鲜重分别增加了209.41%和3035%。由以上结果可以看出,DQSA1具有显著的耐盐碱性能,并能在盐碱胁迫下显著促进拟南芥的生长。在菌株DQSA1的全基因组中,与氨基酸代谢、碳水化合物代谢、膜转运和信号转导相关的基因可能是其具有耐盐碱性和促生效应的分子基础。
