Crop diseases caused by phytopathogens result in great harm to global agriculture. Biocontrol has garnered increasing attention in plant disease prevention and control because of its effectiveness and environmental friendliness. [Objective] To identify, analyze the genome, and evaluate the disease-resistant and plant growth-promoting effects of the strains with antagonistic activities that were screened from the culture collection. [Methods] Antagonistic strains were screened by plate confrontation method. and identified by morphological observation, phylogenetic analysis based on the 16S rRNA gene and genome, comparative analysis of average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values, and physiological and biochemical tests. The whole genome sequence of the target strain was analyzed for the mining of functional genes. The plant growth-promoting effect of the target strain was characterized in terms of the phosphorus-solubilizing, siderophore-producing, and proteinase- and cellulose-producing properties. The inhibition of volatile gas produced by the target strain on phytopathogenic fungi was examined in petri dishes with a septum. The effects of the target strain on tomato growth and diseases were studied by pot experiments. [Results] Strain MB1019 with obvious inhibitory effects on Ralstonia solanacearum and three phytopathogenic fungal strains was screened out and identified as Bacillus velezensis. The physiological and biochemical tests showed that strain MB1019 tolerated the temperature of 15-50 ℃, 10.0% NaCl, and pH 5.0-9.0. The genome of strain MB1019 was 3.8 Mb in length, with the G+C content of 46.4%. The prediction on antiSMASH suggested that the MB1019 genome had 17 synthetic gene clusters for secondary metabolites. The prediction on dbCAN2 suggested that MB1019 carried 108 genes belonging to 52 types of the CAZy family, among which glycoside hydrolases (GHs) were the richest and most abundant. The volatile gas produced by MB1019 significantly inhibited the growth of phytopathogenic fungi. The results of pot experiments showed that MB1019 promoted the growth and inhibited the diseases of tomato seedlings. [Conclusion] B. velezensis MB1019 capable of antagonizing R. solanacearum and phytopathogenic fungi has tolerance to high temperatures and saline-alkali and demonstrates plant growth-promoting effects. Its genome contains a large number of functional genes, and the volatile gas produced by this strain can inhibit the growth of pathogenic fungi. The fermentation broth of MB1019 has the effects of promoting the growth and preventing the diseases of tomato seedlings. In summary, B. velezensis MB1019 can be used as an elite strain in the research and development of microbial fertilizers and pesticides, demonstrating promising development and application prospects.

Crop diseases caused by phytopathogens result in great harm to global agriculture. Biocontrol has garnered increasing attention in plant disease prevention and control because of its effectiveness and environmental friendliness. [Objective] To identify, analyze the genome, and evaluate the disease-resistant and plant growth-promoting effects of the strains with antagonistic activities that were screened from the culture collection. [Methods] Antagonistic strains were screened by plate confrontation method. and identified by morphological observation, phylogenetic analysis based on the 16S rRNA gene and genome, comparative analysis of average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values, and physiological and biochemical tests. The whole genome sequence of the target strain was analyzed for the mining of functional genes. The plant growth-promoting effect of the target strain was characterized in terms of the phosphorus-solubilizing, siderophore-producing, and proteinase- and cellulose-producing properties. The inhibition of volatile gas produced by the target strain on phytopathogenic fungi was examined in petri dishes with a septum. The effects of the target strain on tomato growth and diseases were studied by pot experiments. [Results] Strain MB1019 with obvious inhibitory effects on Ralstonia solanacearum and three phytopathogenic fungal strains was screened out and identified as Bacillus velezensis. The physiological and biochemical tests showed that strain MB1019 tolerated the temperature of 15-50 ℃, 10.0% NaCl, and pH 5.0-9.0. The genome of strain MB1019 was 3.8 Mb in length, with the G+C content of 46.4%. The prediction on antiSMASH suggested that the MB1019 genome had 17 synthetic gene clusters for secondary metabolites. The prediction on dbCAN2 suggested that MB1019 carried 108 genes belonging to 52 types of the CAZy family, among which glycoside hydrolases (GHs) were the richest and most abundant. The volatile gas produced by MB1019 significantly inhibited the growth of phytopathogenic fungi. The results of pot experiments showed that MB1019 promoted the growth and inhibited the diseases of tomato seedlings. [Conclusion] B. velezensis MB1019 capable of antagonizing R. solanacearum and phytopathogenic fungi has tolerance to high temperatures and saline-alkali and demonstrates plant growth-promoting effects. Its genome contains a large number of functional genes, and the volatile gas produced by this strain can inhibit the growth of pathogenic fungi. The fermentation broth of MB1019 has the effects of promoting the growth and preventing the diseases of tomato seedlings. In summary, B. velezensis MB1019 can be used as an elite strain in the research and development of microbial fertilizers and pesticides, demonstrating promising development and application prospects.

植物病原细菌及病原真菌引起的番茄青枯病[1]、香蕉枯萎病[2]、油茶炭疽病[3]等植物病害,给全球作物造成了巨大危害。由于缺乏有效的抗性育种手段,应用化学杀菌剂成为控制植物病原菌的主要方法。然而,部分植物病害缺乏对应的商业化学品,且长期使用化学杀菌剂后,农田病原菌产生了耐药性,几种亚致死浓度的化学杀菌剂的使用会引发真菌毒素的生物合成[4]。生物防治因其有效性及环境友好性等成为防治植物病虫害研究的热点。由于田间环境复杂多变,生防菌难以在土壤中稳定定殖,且缺乏有效的生防效应因子,生物防治面临很大挑战[5]
植物根际促生细菌(plant growth-promoting rhizobacteria, PGPR)是生长在植物根际的有益细菌,它们不仅能够促进植物的生长发育,还能增强植物的抗病和抗逆性,主要包括芽孢杆菌属(Bacillus)、假单胞菌属(Pseudomonas)等[6]。芽孢杆菌广泛存在于自然界,具有繁殖快、代谢快、定殖能力强等特点,其能够产生芽孢以抵抗不良环境,因此成为当前生物农药研究的热点和产业化开发的主要来源。贝莱斯芽胞杆菌(Bacillus velezensis)是芽孢杆菌中最重要的代表性生防菌,被广泛应用于农业生产中[7-8]。贝莱斯芽胞杆菌通过产生多种次级代谢产物,如苯甲醛(benzaldehyde)、表面活性素(surfactin)和杆菌霉素D (bacillomycin D)等抑制病原体和害虫;通过改善宿主植物微生物群落结构,促进宿主对营养的吸收;激发宿主防御机制,诱导产生系统抗性[9-10]。Tahir等[11]从贝莱斯芽孢杆菌(Bacillus velezensis)模式菌株FZB42中鉴定出了抑制茄科罗尔斯通氏菌(简称青枯菌,Ralstonia solanacearum)的挥发性代谢产物,包括苯甲醛、1,2-苯并异噻唑-3-酮[1,2‑benzisothiazol‑3(2 H)‑one]和1,3-丁二烯(1,3‑butadiene);此外,B. velezensis FZB42产生的表面活性素对多种病原微生物具有抑菌活性[11]。Im等[12]研究发现,B. velezensis DR‑08的丁醇提取物含有difficidin和oxydifficidin,对青枯菌有抗菌活性。
本研究从实验室保藏的菌种资源库中筛选拮抗青枯菌和3种植物病原真菌的生防菌株,随后对其进行菌种鉴定、全基因组学分析、促生功能检测、产挥发性气体的抑菌活性检测以及番茄促生防病效果评价。本研究旨在为微生物肥料和农药的研发提供优质的菌种资源,并为深入挖掘菌种的抑菌机理奠定理论基础。

从实验室保藏的菌种库中筛选到1株对青枯菌RSH具有明显拮抗活性的菌株MB1019 (图1A),采用模式图(图1B)的方法检测MB1019对3种病原真菌的抑菌活性,结果显示,与对照相比(图1C1E1G),MB1019对番茄灰霉病菌TSF05 (图1D)、柑橘白地霉病菌TSF19 (图1F)和烟曲霉TSF44 (图1H)具有明显的抑菌活性。
图2A所示,MB1019在NA培养基上呈乳白色,不透明,分泌大量胞外黏液,边缘整齐。扫描电镜结果显示,MB1019呈短杆状,大小为(1.7-2.3) μm×(0.6-0.7) μm (图2B)。
MB1019与暹罗芽孢杆菌(Bacillus siamensis) KCTC 13613T和贝莱斯芽孢杆菌CR-502T序列的相似性最大,均为99.9%。基于16S rRNA基因构建的最大似然法系统发育树显示,MB1019与B. siamensis KCTC 13613T聚在一个分支上(图2C),进一步全基因组系统发育树显示MB1019与B. velezensis CR-502T聚在一个分支上(图2D),表明MB1019可能为一株贝莱斯芽孢杆菌。
MB1019与B. velezensis CR-502T的ANI比值为98.3%,dDDH比值为84.5%,均大于区分物种界限值95.0%-96.0%和70.0%,而与其他菌株ANI比值在77.0%-94.3%之间,dDDH比值在20.4%-56.5%之间(表1),表明MB1019是一株贝莱斯芽孢杆菌。
菌株MB1019的生理生化特征见表2,其氧化酶和还原酶活性均为阴性,生长温度范围为15-50 ℃,最大耐受NaCl浓度为10.0%,耐受pH值范围为5.0-9.0。菌株MB1019在NA、R2A、MCA和TSA这4种培养基上均能生长。IMViC生化系统鉴定结果显示,菌株MB1019的甲基红试验为阴性,吲哚试验为阳性,柠檬酸盐利用试验为阳性,VP试验为阳性。
菌株MB1019全基因组基本特征见表3,基因组大小为3.8 Mb,G+C含量为46.4%,草图基因组中含有31个contigs,包含3 984个基因。
antiSMASH在线数据库预测菌株MB1019基因组中含有17个次级代谢产物基因簇,其中有4个基因簇展示与bacillibactin、bacilysin、bacillaene和macrolactin H均有100%相似性,片段6.2编码一个PKS-like基因簇,与已知基因簇butirosin A/butirosin B相似性仅有7% (表4),此外,4个片段6.1、7.2、10.1及11.1编码的terpene、T3PKS、terpene和lanthipetide-class-ii未检测出最相似基因簇(表4)。
菌株MB1019基因组中共含有52种、共108个CAZy家族基因,其中糖苷水解酶(glycoside hydrolases, GHs)家族种类和数量最多,分别为24种和42个(图3A)。图3B进一步展示了菌株MB1019基因组中含有的糖苷水解酶家族种类和数量,其中GH13和GH43含有的数量最多,分别为6个和4个。
菌株MB1019在溶无机磷、CAS检测、脱脂牛奶及羧甲基纤维素钠培养基上均能形成明显的水解圈(图4A-4D),表明菌株MB1019具有溶无机磷、产铁载体、产蛋白酶和纤维素酶活性。
定量检测培养3 d的菌株MB1019发酵液中的溶无机磷、产铁载体、产蛋白酶和纤维素酶活力。结果显示,菌株MB1019的溶解无机磷能力为(51.440±0.001) mg/L,产铁载体能力为(55.70±0.19)%,产蛋白酶活力为(22.008±2.171) U/mL,产纤维素酶活力为(0.022 1±0.001 2) U/mL。
与单独培养2株植物病原真菌相比(图5A5C),在二分隔培养皿中,菌株MB1019的生长对番茄灰霉病菌TSF05和柑橘白地霉病菌TSF19具有显著的抑菌效果(图5B5D5E),表明菌株MB1019产生的挥发性气体能够有效抑制这2种植物病原真菌。
将生长30 d的4个处理组的番茄苗的株高、根长、鲜重、干重以及鲜重-干重值进行统计,结果如图6所示,与灭菌的NB液体培养基(CK)相比,接种菌株MB1019发酵液后,番茄的株高、根长、鲜重和干重分别提高了32.4%、31.2%、50.9%和37.0% (MB1019)。此外,施加青枯菌RSH的番茄苗植株明显变矮,部分植株出现枯萎症状(RSH)。然而,与青枯菌RSH组相比,当同时施加菌株MB1019和RSH后,番茄苗植株恢复生长,且株高、根长、鲜重和干重分别提高了39.0%、58.6%、94.1%和74.1% (MB1019+RSH)。盆栽试验结果表明,菌株MB1019对番茄具有明显的促生作用,并且能够有效防治青枯病。
近年来,芽孢杆菌等PGPR在农业生产上被广泛应用,以防治植物病害并促进作物生长[17]。然而,对于这些细菌促进生长及适应环境的分子机制仍有许多未知之处。本研究筛选到一株对植物病原细菌和真菌有明显抑菌作用的菌株MB1019 (图1),经表型分析、系统发育分析、基因组ANI和dDDH比较分析以及生理生化特征等鉴定,确认该菌株为贝莱斯芽孢杆菌(图2表1表2),并且发现菌株MB1019具有溶磷和产铁载体等促生特征(图4A4B),表明MB1019是一株PGPR。此外,菌株MB1019展现出多种抗性特征,包括耐高温(50 ℃)、最高耐NaCl浓度为10.0%、耐酸碱性范围pH 5.0-9.0等(表2)。
多株贝莱斯芽孢杆菌已被报道有拮抗病原菌功能,包括FZB42、GS-1、BA-26、BS1等[7,18]。它们可通过产生次级代谢产物抑制多种病原真菌和细菌。在本研究中,菌株MB1019的基因组被预测含有17个次级代谢产物基因簇(表4),其中difficidin、macrolactin H和bacilysin主要抑制病原真菌,而bacillaene、fengycin和surfactin则能有效抑制病原细菌,bacillibactin能够抑制微生物的竞争对手[19]。此外,有2个基因簇编码terpenes,1个基因簇编码T3PKS和1个基因簇编码lanthipetide (表4)。Lanthipetides是核糖体合成和翻译后修饰肽,具有抗细菌、抗真菌及其他活性[20]。Terpene一般具有挥发性,包括a-pinene和氧化terpene,是挥发性的抗菌化合物,与本研究发现菌株MB1019产生挥发性气体以抑制病原真菌的结果相一致(图5)[21-22]
我们也发现菌株MB1019具有产生蛋白酶和纤维素酶活力(图4C4D),这些酶活性已被报道有助于拮抗病原菌及防治植物病害[23]。PGPRs能够通过分泌蛋白酶、纤维素酶、葡聚糖酶及几丁质酶来降解真菌细胞壁,如几丁质、葡聚糖和蛋白质,从而破坏细胞壁的完整性,进而降低病原菌的致病力[24]。我们推测菌株MB1019的抗真菌活性与其分泌的这些胞外水解酶的分解能力密切相关。
青枯菌侵染引起的番茄青枯病素有 “植物癌症” 之称,是一种毁灭性的土传病害,也是番茄主要病害之一[25-26]。盆栽结果显示,接种菌株MB1019发酵液对番茄青枯病有显著的抑菌效果,并且对番茄有明显的促生作用(图6)。综上所述,贝莱斯芽孢杆菌MB1019展示了广谱高效地拮抗病原细菌和真菌的活性,具有溶磷和产铁载体等促生特性,能够产生具有抑菌活性的多种次级代谢产物,以及蛋白酶和纤维素酶。因此,MB1019是一株有应用价值的安全有效的防治青枯病的生防细菌,在环境友好的农业生态中值得深入探索它的生防应用。
