Panama wilt caused by f. sp. (Foc) is one of the major disease constraints of banana production. Previously, we reported the disease resistance puttabale clones developed from Ethylmethanesulfonate and Foc culture filtrate against Foc inoculation. Here, the same resistant clones and susceptible clones were used for the study of protein accumulation against Foc inoculation by two-dimensional gel electrophoresis (2-DE), their expression pattern and an approach. The present investigation revealed mass-spectrometry identified 16 proteins that were over accumulated and 5 proteins that were under accumulated as compared to the control. The polyphosphoinositide binding protein ssh2p (PBPssh2p) and Indoleacetic acid-induced-like (IAA) protein showed significant up-regulation and down-regulation. The docking of the pathogenesis-related protein (PR) with the fungal protein endopolygalacturonase (PG) exemplify the three ionic interactions and seven hydrophobic residues that tends to good interaction at the active site of PG with free energy of assembly dissociation (1.5 kcal/mol). The protein-ligand docking of the Peptide methionine sulfoxide reductase chloroplastic-like protein (PMSRc) with the ligand β-1,3 glucan showed minimum binding energy (-6.48 kcal/mol) and docking energy (-8.2 kcal/mol) with an interaction of nine amino-acid residues. These explorations accelerate the research in designing the host pathogen interaction studies for the better management of diseases.
由尖孢镰刀菌古巴专化型(Foc)引起的巴拿马枯萎病是香蕉生产的主要病害限制因素之一。此前,我们报道了通过甲基磺酸乙酯和Foc培养滤液培育出的对Foc接种具有抗病性的可育无性系。在此,使用相同的抗病无性系和感病无性系,通过二维凝胶电泳(2-DE)研究了接种Foc后蛋白质的积累情况、它们的表达模式及一种方法。本研究表明,与对照相比,质谱鉴定出16种蛋白质积累过多,5种蛋白质积累过少。多磷酸肌醇结合蛋白ssh2p(PBPssh2p)和吲哚乙酸诱导样(IAA)蛋白表现出显著的上调和下调。病程相关蛋白(PR)与真菌蛋白内切多聚半乳糖醛酸酶(PG)的对接展示了三种离子相互作用和七个疏水残基,这些在PG的活性位点倾向于良好的相互作用,组装解离自由能为1.5千卡/摩尔。叶绿体样肽甲硫氨酸亚砜还原酶蛋白(PMSRc)与配体β-1,3-葡聚糖的蛋白质-配体对接显示出最小结合能(-6.48千卡/摩尔)和对接能(-8.2千卡/摩尔),有九个氨基酸残基相互作用。这些探索加速了为更好地管理病害而设计宿主-病原体相互作用研究的进程。
