Recent work in Arabidopsis demonstrates the molecular basis of this memory of winter: vernalization causes changes in the chromatin strcture of a flowering repressor gene, FLOWERING LOCUS, that switch this gene into a repressed state that is mitotically stable.

最近对拟南芥的研究显示了植物记忆冬季的分子基础：促进成熟促使一个开花抑制基因（FLOWERING LOCUS C，FLC）的染色质结构的改变，这种改变使这个基因从抑制状态转为有丝分裂稳定。

Recently, a variety of regulatory proteins including DNA methyltransferases, methyl-CpG binding proteins, histone-modifying enzymes, chromatin remodeling factors, and their multimolecular complexes have been identified.

最近，包括DNA转甲基酶，CpG甲基化结合蛋白质，组蛋白修饰酶，染色质重构因子，和它们的多分子复合物等各种调控蛋白质被识别。

Results Infected by this peptide, cell viability decreased 28.9%. Under light microscope, cells were shrinked and rounded, many cells were divorced from plate wall, some neuraxon shortened and broke. Apoptotic cells which nucleolus shrinked and rounded could be coloured orange by fluorescent colouration. Under electron microscope, chromatin gathered along the inside of the nuclear membrane, vacuole bodies appeared. Apoptotic peak was detected by flow cytometry and the ladder band appeared in DNA electrophoresis.

结果：细胞接触肽段后存活率下降28.9％；光镜下可见细胞贴壁不良，胞体缩小，细胞突起断裂缩短；荧光染色可见细胞突起缩短、胞核固缩、胞质染成橘红色的凋亡细胞；电镜下可见胞质中出现空泡样结构，细胞染色质浓集于核膜内侧并裂解成碎块状；流式细胞仪检测细胞出现亚二倍体峰，DNA电泳出现梯状带。

At high magnification, the non-Hodgkin's lymphoma cells have prominent clumped chromatin and nucleoli with occasional mitotic figures.

在高倍镜下可见非霍奇金淋巴瘤细胞的细胞质浓缩，偶尔可见病理性核分裂像。

All cells were generally smaller and occasionally spindled, the chromatin detail was attenuated, and nucleoli were more prominent.

所有的细胞都稍小，偶见梭形，染色质不清，核仁突出。
