After reviewing the previous dissertation on quantitative characteristic trait of recalcitrant seeds, three aspects of quantitative characteristic trait of seed recalcitrant were defined, which are interspecific aspect, intraspecific aspect and individual developmental aspect. And it was supposed that seed recalcitrance was a compound characteristic, with its core composed of desiccation tolerance, low-temperature tolerance and storage tolerance at least, and its concomitants composed of seed size, 1000-seed weight, moisture content at shedding, non-dormancy, systemic taxonomy, ecological and biochemical aspects. Because these core and concomitants are all gradual, transitional and quantitative, it was inferred that seed recalcitrance was a compound quantitative trait.

文章简要概述了从顽拗型种子到顽拗性种子这样一个对顽拗性种子认识提高的过程,在综述了前人关于顽拗性种子数量性状特征论述的基础上,把种子顽拗性的数量性状特征划分为种间、种内和个体发育三个层面,提出种子顽拗性是一种复合性状,其核心至少包括脱水耐性、低温耐性和贮藏耐性三方面的内容,其伴随性状包括种子尺度、千粒重、初始含水量、休眠特性、分类地位、地理分布和保护性物质含量等多方面的内容,而且这些核心内容和伴随性状的每一个方面都具有渐变的、过渡的、数量型的特征,从而阐明种子顽拗性是一种复合数量性状。

Then we transfected transitorily the recombinant of green fluorescent protein gene and middle molecular weight neurofilament cDNA into wide type N2a (N2a/wt) and N2a/tau40 to observe the effect of tau accumulation on GFP-NFM fusion protein transport in cellular processes in living cells. At last we used an apoptotic inducer, camptothecin (an inhibitor of topoisomerase-1) to treat N2a/wt and N2a/tau40 cell lines, and compared their apoptotic response.

主要结果如下:一、tau蛋白过度表达和聚积对细胞形态的影响:倒置显微镜下观察两种细胞的形态,发现N2a/wt细胞的突起多而长,而N2a/tau40细胞胞体变圆,突起明显缩短;免疫印迹结果显示转染了tau40的细胞内tau的免疫反应约增加14倍,免疫荧光结果显示N2a/tau40细胞胞体内呈现出较强的红色荧光,tau主要分布在核周和突起起始部分的胞质内,而N2a/wt细胞内的荧光很弱。
