摘要: 通过比较育秧肥和化肥作基肥的早稻秧苗质量的差异,及在这两种育秧条件下水稻叶片的蛋白质组表达差异,揭示了育秧肥的壮秧机理。结果表明,育秧肥具有促进秧苗分蘖和发根,使秧苗矮壮,提高秧苗叶绿素含量和光合生产能力,提高秧苗综合素质等作用。经双向电泳分离,获得了18个不同处理下发生差异表达的蛋白质。经质谱分析,其中16个蛋白质得到鉴定,包括9个参与光合作用的蛋白质,3个与蛋白质合成密切相关的蛋白质以及3个与抗性相关的蛋白质和1个未知功能蛋白质。

Abstract: The differences in  leaf  expressed proteome of early  rice seedlings   with   seedlingraising fertilizer and chemical fertilizer as basal fertilizer  were compared to reveal the mechanism that   seedlingraising fertilizer  application  improved rice seedling quality. The seedlingraising fertilizer could promote tillering and root growing, help form stocky plants, increase chlorophyll content and promote photosynthesis, finally improve  comprehensive quality of seedlings. Proteins collected from rice seedling leaves were analyzed using twodimensional electrophoresis in combination with biomass spectrometry. According to  the protein expression profiles,  the  expression levels  of 18 protein spots altered under the two cultivation conditions. Among the 18 protein spots, 16 proteins were identified, including nine proteins involved in photosynthesis, three proteins in stress resistance, three proteins in protein synthesis and  one  functionunknown protein.
