Description

含有二肽衍生物作为活性成分的农业植物-保护剂
【技术领域】
本发明涉及包含二肽衍生物或其农药学可接受的盐作为活性成分的农业植物-保护剂,其具有植物疾病-预防效应,植物生长-促进效应,及植物免疫-活化效应。
【背景技术】
当植物被病原体侵袭或受物理损伤时,为防御目的而产生信号传导分子。已知,该信号传导分子具有作为植物防御活化物,植物加强剂,或植物免疫活化物的效应。作为植物的代表性的信号传导分子,已知道水杨酸和茉莉酸。当由于外部侵入而植物的防御反应发挥作用时,水杨酸(信号传导分子)诱导植物中基因,诸如,PR-1,BGL-2,PR-5,SID-2,EDS-5和PAD-4表达,及茉莉酸诱导植物中基因,诸如,PDF1.2,VSP,HEL,THI-2,FAD3,ERS1和ERF1表达[Dong,X.,Current Opinion in Plant Biology,1998,1,316-323;Glazebrook,J.,Current Opinion in Plant Biology,1999,2,280-286;Bostock,R.M.,Physiology andMolecular Plant Pathology,1999,55,99-109]。特别是,PR-1基因是指示由水杨酸产生的植物抗性-诱导现象的基因,PR-1基因的表达是植物中信号传导过程起动的关键的证据。当植物中PR蛋白表达时,植物显示疾病抗性效应诸如抗细菌性活性。此外,PDF1.2基因是指示由茉莉酸诱导的植物抗性-诱导现象的基因,PDF1.2基因的表达是植物的防御反应起动的信号传导过程进行的关键的证据。
苯并-1,2,3-噻二唑-7-硫代羧酸S-乙基酯(BTH)已商业上用作植物的信号传导分子。BTH是与水杨酸具有类似化学结构的合成化合物。已报道BTH显示抑制导致大麦白粉病的布氏白粉菌(Blumeria graminis)的活性,植物的臭氧抗性,在葡萄植物中呈现对灰葡萄孢(Botrytis cinerea)的抗性,促进白藜芦醇和花青苷生物合成的活性,在草莓中对白粉病的抗性,及也具有酚化合物的蓄积效应。BTH如水杨酸一样具有诱导PR-1基因表达的功能,但不诱导由茉莉酸呈现的PDF1.2基因的表达。
如上所述,当用于植物的自身-防御的信号传导分子诸如水杨酸和茉莉酸诱导基因诸如PR-1或PDF1.2的表达时,植物可抑制病原体的繁殖,也可忍耐物理创伤。换言之,被认为在植物中诱导自身-防御能力。因此,即便未处理常规抗微生物剂或杀菌剂,当该基因在植物中表达时,植物可抵抗病原体。因此认为,使该基因表达的分子作为植物用农业药物具有大的价值。
同时,二肽是具有通过2个氨基酸缩合产生的酰胺键的肽分子。二肽甚至在实施蛋白水解时也以各种类型的结构产生,及甚至还在合成2,5-哌嗪二酮,环状二肽的过程期间产生。阿司帕坦,即,人工甜味剂,属于由2个氨基酸组成的二肽。据至今报道,二肽化合物主要作为人工甜味剂,血小板聚集抑制物等应用[国际专利公开No。WO9616981,US专利No.5,968,581和5,763,408,及欧洲专利公开No.513675]。
本发明人合成了由2个氨基酸制成的二肽衍生物,及发现,当用这些化合物处理植物时,它们表达植物疾病-抵抗基因诸如PR-1,葡聚糖酶,几丁质酶,PR4,过氧化物酶和PR10。此外,我们发现,当用二肽衍生物处理形成损伤之前的植物时,显著地抑制植物中损伤的形成,及除了植物疾病-预防效应之外,也改善植物生长-促进效应和植物免疫-增加效应(详细而言,植物疾病-抵抗能力或植物冷害-预防能力)。由此,本发明人完成了本发明。
换言之,本发明人首次发现,二肽衍生物诱导疾病抗性基因表达,及通过抑制病原体的增殖而显示植物疾病-预防效应,植物生长-促进效应,及植物免疫-增加,而至今这尚未报道于任何现有技术文献。
【发明内容】
【发明要解决的技术课题】
本发明旨在提供二肽衍生物作为农业植物-保护剂的用途。
【解决课题的技术方案】
为了达到该目的,本发明提供农业植物-保护剂,其包含选自以下化学式1所示的二肽衍生物或其农药学可接受的盐的化合物作为活性成分。
[化学式1]
在以上化学式1中,
R1,R2和R5彼此相同或不同,且表示氢原子、线性或分支的C1~C18烷基羰基、线性或分支的C1~C18烷氧基羰基、

此外,本发明提供预防或抑制植物疾病的方法,所述方法包括用包含选自以上化学式1所示的二肽衍生物或其农药学可接受的盐作为活性成分的化合物的农业植物-保护剂处理植物。
此外,本发明提供活化植物免疫的方法,所述方法包括用包含选自以上化学式1所示的二肽衍生物或其农药学可接受的盐作为活性成分的化合物的农业植物-保护剂处理植物。
此外,本发明提供促进植物生长的方法,所述方法包括用包含选自以上化学式1所示的二肽衍生物或其农药学可接受的盐作为活性成分的化合物的农业植物-保护剂处理植物。
【发明效果】
当处理植物时,本发明的农业植物-保护剂由于通过表达植物疾病-抵抗基因诸如PR-1,葡聚糖酶,几丁质酶,PR4,过氧化物酶和PR10,由此诱导植物疾病-抵抗蛋白的产生而阻遏病原体的感染和增殖,从而具有显著地减少植物中损伤形成的效应。此外,本发明的农业植物-保护剂允许植物活化针对病原体的疾病抗性机理或通过起动自身-防御机理来保护自身免于冷害。此外,本发明的农业植物-保护剂允许植物耐受由寒冷或热气候条件导致的环境应激,及也具有促进植物生长的效应。
此外,本发明的农业植物-保护剂由植物的自身-防御机理而具有系统性效应,即该效也在未处理的其他区显现。换言之,即使剂处理植物的一部分,诸如植物的种子,根,茎和叶,其在其他未处理的区,及甚至在收获的果实上也具有效应。
由于农业植物-保护剂对预防由细菌,病毒,或霉菌导致的植物疾病诸如细菌性软化病,猝倒病,疫霉枯萎病,萎缩病,叶斑病或花叶病具有优良效果,其作为能取代常规杀菌剂使用的环境-友好的农业植物-保护剂有用。

本发明的农业植物-保护剂可包含,作为活性成分,单独,上述化学式1所示的二肽衍生物或农药学可接受的盐。此外,本发明的农业植物-保护剂包含0.001~99wt%,及优选0.005~30wt%的活性成分,及可还另外包含赋形剂。赋形剂可为通用的微生物制剂,抗细菌剂效应-促进剂,稀释剂或载体。除了本发明的农业活性成分之外,为增加处理效应或扩大应用范围的目的而,还可以特定含量范围包含被常规商业化使用的,或开发的其他杀菌剂,杀昆虫剂,除草剂,植物生长-控制剂或肥料而配制成混合制剂类型。
本发明的农业植物-保护剂中包含的赋形剂及稀释剂是农业领域通常使用的,且可包括向其还添加固体载体,例如,氧化物,诸如,硅藻土和熟石灰,磷酸盐,诸如,磷灰石,硫酸盐,诸如,石膏和矿物质粉,诸如,粘土,高岭土,膨润土,酸粘土,石英和氧化硅,及填料,抗-聚集剂,表面活性剂,乳化剂,及防腐剂。此外,本发明的农业药物可通过使用本领域所知的方法配制成以迅速释放,持续释放及延迟释放的类型释放活性成分。为了制剂化,将通常使用的添加剂,诸如,表面活性剂,稀释剂,分散剂和佐剂与活性成分混合,然后,由此获得的混合物可配制为各种类型,诸如,水分散性粉剂,悬浮液,乳剂,可乳化的浓缩物,微乳剂,液体制剂,可分散制剂,颗粒水分散性粉剂,颗粒剂,粉末化药剂,液体水分散性粉剂,颗粒水分散性粉剂,浮水颗粒剂,及片剂而使用。
本发明的农业植物-保护剂可通过使用通用的方法应用于植物。对于将其应用于植物而言,其可直接喷或涂到植物体的叶,茎,枝,根和种子;可与通用的培养土壤,诸如,水稻田或旱田或苗圃床土壤或培养基混合;或,在水中培养的植物体的情况中,可处理到水的表面,以便预防疾病损伤。作为特定应用方法,可有涂敷处理,浸处理,熏蒸处理,或喷处理。例如,农业植物-保护剂可喷到土壤,或植物的叶,茎,种子,花或果实。为了向植物应用本发明的农业植物-保护剂,该剂可用水或适当的培养基稀释后使用。
为了确认植物疾病诱导性抗性(ISR)效应,植物生长-促进效应,及冷害-克服效应,实施多角度实验。
首先,用本发明的二肽衍生物处理辣椒植物,然后测量主要防御基因,例如,抗生素基因,诸如,PR-1,β-1,3-葡聚糖酶,几丁质酶,PR4,过氧化物酶和PR10引物的表达程度。确认,相比对照组,用上述化学式1所示的二肽衍生物处理的测试组中抑制植物疾病暴发的基因表达显著地增加。此外,也确认,防御基因在用植物病原体接种之前在仅用该剂处理时未表达,但在用植物病原体,诸如,细菌性软化病的病原体(胡萝卜软腐果胶杆菌(Pectobacterium carotovora)SCC1)和疫霉的病原体(辣椒疫霉(Phytophthoracapsici))感染的植物中抗性机理起动(见图1)。这便是所谓“增强作用(potentiation)”的现象。因此,可发现,本发明的农业植物-保护剂对抑制病原体的感染和繁殖具有优良效果,由此,预防或治疗植物疾病的暴发。用本发明的二肽衍生物处理结合了由PR-1α疾病抗性启动子诱导的GUS基因的烟草叶的结果,可确认,PR-1αGUS活性相比对照组显著地增加(见图2)。此外,为了确认通过用本发明的农业植物-保护剂处理植物来抑制植物疾病暴发的效应,以植物,诸如,烟草,白菜,黄瓜,辣椒和卷心菜作为对象,测试上述化学式1所示的二肽衍生物的溶液对抑制细菌性软化病或炭疽病的效应。可确认,当用上述化学式1所示的二肽衍生物处理植物时,其抑制植物疾病暴发的效应相比非-处理的组或对照药物(BTH)-处理的组显著地改善(见图3)。从观察通过用二肽衍生物处理种子,然后使种子生长而制备的植物叶上植物疾病暴发的阻遏程度的结果可确认,损伤形成相比非-处理的组大大地被抑制(见图4)。由此原因,可确认,当用本发明的二肽衍生物处理叶或茎时,抑制损伤的效应是优良的,及,甚至当用其处理种子时,也可抑制损伤形成。可确认,当将化合物89,91,93和107(本发明的二肽衍生物)直接喷到植物叶时,在用植物病原体感染植物之后,抑制辣椒疫霉枯萎病或细菌性软化病暴发的效应相比非-处理的对照组优良(见表7,及图5,7和9)。此外,可确认,当用化合物4,94,95和107(本发明的二肽化合物)浸透-处理植物的根时,叶上疫霉枯萎病的暴发显著地降低(见图6和8)。此外,当将本发明的二肽化合物喷到辣椒植物的叶,用辣椒疫霉(辣椒疫霉(Phytophthora capsici))感染植物的根,然后观察根和叶上的损伤形成时,叶和根上的损伤形成相比对照组显著地降低(见图10)。
此外,可确认,当用本发明的农业植物-保护剂处理植物时,植物生长促进相比非-处理的组达最大24.4%(见图6)。本发明的二肽化合物对防止植物冷害呈现优良效果,及当使得用二肽化合物浸透-处理或喷的叶在低温下暴露特定时间以使经历冷害时,叶呈现优良的克服冷害而恢复原状态的能力(见图11和12)。
如上所述,本发明的农业植物-保护剂可诱导植物疾病抗性;也可呈现促进生长的效应;及可呈现忍耐物理应激诸如冷害的效应。因此,本发明的剂在作为具有与常规植物-保护剂完全不同的作用机理的下一代农业植物-保护剂应用时具有非常高的价值。本发明的农业植物-保护剂的植物疾病-预防效应,植物生长-促进效应,及植物免疫-活化效应(植物疾病-抵抗效应和冷害-预防效应)会更详细描述于下列实施例。

将由合成方法A和B获得的N-Boc-氨基酸-氨基酸烷基酯再次溶解于水溶性二噁烷,向其添加相当量的LiOH,然后将由此获得的混合物搅拌过夜。然后,将由此获得的混合物与乙酸中和,及用丙酮/乙醇的混合的溶剂萃取3次而获得无烷基的氨基酸-氨基酸。
【(5)二肽合成方法E(化合物96~105)】
将由合成方法C获得的氨基酸-氨基酸烷基酯盐(0.57mmol)溶于二氯甲烷(5mL),向其添加酰基氯(1.2eq)及三乙基胺(2.4eq),然后将由此获得的反应混合物于室温搅拌2小时。将由此获得的反应混合物添加到EtOAc(50mL),用1M HCl溶液,碳酸钠及饱和的盐水洗涤,然后浓缩。将由此获得的浓缩的溶液通过氧化硅柱色谱仪(EtOAc/己烷)纯化而以90%或更大的收率获得N-酰基氨基酸-氨基酸烷基酯。

然后,在12,24和48小时之后,收集1g量的相应辣椒叶,然后储存于-75℃的超低温室。将储存的植物叶随液氮粉碎,然后,通过使用RNA提取试剂盒(EASY-SPINTMIIP总RNA提取试剂盒,Intron Biotechnology,韩国)和由Kishimoto等人(2005)的Ex Taq聚合酶(TakaraBiomedicals,Otsu,日本)提取rRNA。为扩增,将0.1μg的cDNA,10pMol的各正向及反向引物,250nM的dNTP,及0.5U的Ex Taq聚合酶添加到20μL的缓冲溶液。于94℃和58℃在热循环仪(PTC-100,USA)中实施PCR,及在1%琼脂糖凝胶(在0.5×TAE缓冲剂中)(80V,60min)条件下分析由PCR产生的产物。全部RT-PCR测试重复两次。

【实施例3.对抑制植物疾病暴发的效应】
在向各种植物处理本发明的化合物之后,在以下方法中测量化合物对抑制植物疾病暴发的效应。
在直径10cm×高13cm的塑料盆中播种烟草或黄瓜,然后,将12个盆加入黄箱。在接种之后,将100μL接种到第1个叶开始出来的黄瓜或烟草的子叶。测试化合物将溶于20%甲醇~制造浓储物溶液,然后,将浓储物溶液稀释到1,10和100ppm的浓度。
在7天之后,将植物细菌性软化病的病原体(胡萝卜软腐果胶杆菌(Pectobacteriumcarotovora)SCC1)在TSA培养基中培养27小时;然后,向植物叶以108cfu/mL的浓度喷培养的病原体,及于30℃培养3天。将植物炭疽病菌(豆状毛盘孢(Colletotrichumorbiculare))在GBA(四季豆琼脂)培养基中培养,以诱导孢子约2~3周。以105细胞/mL的浓度喷菌,然后于26℃培养1天。当出来第4个或第5个叶时,向第3个叶接种200μL的各测试化合物。在7天之后,以108cfu/mL的浓度向植物叶喷植物细菌性软化病的病原体,然后于30℃培养3天。
肉眼实施调查,及根据细菌性软化病的软化程度研究0~100%的损伤相对面积。通过对叶上发生的损伤数进行计数来研究炭疽病。
对抑制对烟草植物的细菌性软化病的暴发的效应的测试结果示于图3的照片,及列于以下表3~6。
【表3】
【表4】
【表5】
【表6】
【实施例4.由种子处理对抑制黄瓜叶上疾病暴发的效应】
将化合物61或化合物74以100ppm的浓度沉积在黄瓜种子2小时,及在3周之后,以105孢子/mL的浓度向其喷炭疽病菌(豆状毛盘孢(Colletotrichum orbiculare))的孢子,然后,在7天之后,研究疾病发生。由此获得的结果示于图4的照片中。
根据图4可确认,相比非-处理的组,在用化合物61或化合物74处理的黄瓜叶上难以发现炭疽病。
以与实施例3相同的方法生长辣椒,然后,将测试化合物溶于20%甲醇,以制造浓储物溶液,及将浓储物稀释至0.1,1.0和10.0ppm的浓度。向叶喷或向叶浸透测试溶液。在7天之后,将植物细菌性软化病的病原体(胡萝卜软腐果胶杆菌(Pectobacteriumcarotovora)SCC1)在TSA培养基中培养27小时,然后,在8mm直径纸圆盘上,以108cfu/mL的浓度润湿。使纸圆盘位于切成圆形的叶的中心,然后,在约7天之后,测量损伤区。在疫霉的情况中,将培养疫霉(辣椒疫霉(Phytophthora capsici))的马铃薯琼脂培养基用穿孔器切成5mm内径尺寸,然后接种到叶上。在7天之后,观察损伤区。在细菌性软化病的情况中,当将化合物6,89,93和95喷射于辣椒叶时,相比非-处理的组,以1或10ppm的浓度未发现细菌性软化病。此外,为辣椒疫霉测试,当以1.0或10.0ppm的浓度浸透-处理化合物89,94,95和107和向叶喷射化合物107(1或0.1ppm)时,无损伤形成。尤其是,可确认,相比对照药物BTH,化合物89对阻遏辣椒疫霉枯萎病的发生呈现优良效果(见图7)。上述测试结果指示,这些化合物在植物中诱导疾病抗性,及抑制细菌性软化病或疫霉的病原体产生,由此提示,这些物质可用作农业杀菌剂。当向根浸透-处理这些化合物时,对叶上损伤形成的阻遏可被解释为,其由在全体植物中诱导系统性疾病抗性而得到。这些测试结果示于图5~9的照片。

【实施例6.对抑制辣椒根中疫霉枯萎病的效应】
用与实施例3相同的方法生长辣椒,将化合物85喷到叶上,然后在1周之后,浸透-接种辣椒疫霉(Phytophthora capsici)游动孢子悬浮液。一边观察7天,一边研究叶和根上的损伤形成。与对照组相比,对于用化合物85处理的辣椒,显著地抑制叶和根上的疫霉枯萎病。化合物85抑制疫霉枯萎病的暴发的测试结果示于图10。
【实施例7.对促进植物生长的效应】
用活性成分(化合物5~8,14和15)浸透植物(辣椒,马铃薯,番茄,烟草,黄瓜和白菜)的叶,然后,在7天之后,测量植物长度。然后,接种植物疾病病原体,然后,在3~5天之后,测量植物叶的尺寸及与对照组比较而获得相对生长程度。将促进黄瓜叶生长的效应列于以下表8。
【表8】
从上述表8中所列的根据结果可确认,当用本发明的二肽衍生物处理时,促进黄瓜生长。因此,可确认,本发明的化合物诱导植物疾病-抗性,并也诱导植物生长-促进效应。也可认为,生长-促进能力是免于疾病的植物-保护能力的互补效能。
【实施例8.对克服辣椒植物上的冷害的效应】
为了确认本发明的化合物的免疫-活化效应,使植物暴露于可受人工冷害的温度,及观察生长和发育。在植物生长6周之后,将化合物浸透或喷到叶,和使植物生长1周。在使植物暴露在2℃生长室1天之后,使它们于室温生长3天。观察植物的生长和发育的程度及测定植物受冷害的程度。当用化合物95浸透-处理植物时,不受冷害。当喷到叶时,在用化合物90,91,93和95处理时也未观察到植物受冷害。由测试结果可确认,当应用化合物时,植物呈现疾病抗性和也诱导能甚至在物理有害环境(如冷害)下维持生长和发育的免疫-活化效应。测试结果示于图11和12的照片。
