摘要: 为探究促芽肥对头季稻的调控效应,以Ⅱ优1273为材料,在头季稻齐穗后18d设置施用促芽肥和未施用促芽肥2种处理,采用比较蛋白质组学的方法和技术,并结合相关生理指标测定,分析了促芽肥对头季稻灌浆后期叶片蛋白质表达及相应生理特性的影响。不同促芽肥处理的头季稻灌浆后期叶片蛋白质经双向电泳分离后共获得了15个差异表达的蛋白质点,涉及头季稻灌浆后期叶片的光合碳同化、电子传递与光合磷酸化和抗逆抗衰老响应等,分析结果表明,头季稻后期剑叶中与光合碳同化、电子传递与光合磷酸化相关蛋白随灌浆进程呈下降趋势,施用促芽肥能明显减缓其下调幅度,从而使头季稻灌浆后期剑叶具有相对较高的叶绿素含量和净光合速率,提高了头季稻灌浆后期的干物质积累和源供应能力;还能明显提高头季稻灌浆后期剑叶中与抗性相关蛋白的表达量,从而增强稻株的活性氧清除能力,抑制功能叶的膜脂过氧化作用,延缓头季稻灌浆后期剑叶的衰老速率,从而显著提高了头季稻的结实率和产量。

Abstract: By using comparative proteomics combined with bioinformatics and related physiological indicators,this paper studied the regulating effects of nitrogen application for bud development on protein expression of flag leaf at late grain filling stage in the first cropping rice with ⅡYou 1273 as a material.Two treatments of urea levels:300.00,0.00 kg/ha applying at 18 d after heading stage were included in the experiment in the first cropping rice.A total of 15 differentially expressed proteins were detected in different fertilizer treatments by the 2D maps of flag leaf proteome.And these proteins were grouped into three expression patterns according to their functions in photosynthesis carbon assimilation,electron-transfer and photophosphorylation,the defense response to stresses etc..Our results indicated that the proteins involving photosynthesis were down-regulated at late grain filling stage in the first cropping rice.But,nitrogen application for bud development could significantly slow down the decreased amplitude of photosynthesis-related proteins in expression abundance,which relatively enhanced the chlorophyll content and photosynthetic rate of functional leaf and increased the source supply ability at late grain filling stage in the first cropping rice.The result also showed that nitrogen application for bud development could significantly increase the expression abundance of resistance-related protein at late grain filling stage in the first cropping rice,which helped enhance the scavenging of active oxygen,retard the peroxidation of membrane lipid and delay the senescence rate of flag leaf.As a result,the seed-setting rate and yield of the first cropping rice were significantly increased under NA treatment.
