In the la.t two deca.es the study of red blood cell ela.ticity using optica. tweezers ha. known a.rise a.pea.ing in the scientific resea.ch with rega.d to the va.ious works ca.ried out. Despite the va.ious work done, no study ha. been done so fa. to study the influence of friction on the red blood cell indenta.ion response using optica. tweezers. In this study, we ha.e developed a.new a.proa.h to determine the coefficient of friction a. well a. the frictiona. forces of the red blood cell. This a.proa.h therefore a.lowed us to simulta.eously ca.ry out the indenta.ion a.d tra.tion test, which a.lowed us to extra.t the interfa.ia. properties of the microbea. red blood cell couple, a.ong other things, the friction coefficient. This property would be extremely importa.t to investiga.e the surviva. a.d mecha.ica. fea.ures of cells, which will be of grea. physiologica. a.d pa.hologica. significa.ce. But ta.ing into a.count the hypothesis of friction a. defined by the isotropic Coulomb la.. The experiment performed for this purpose is the Brinell Ha.dness Test (DB).

DNa.基化修饰对于植物的生长发育十分重要,而MET1是植物中重要的甲基转移酶,能维持植物的CG位点甲基化修饰。为了研究葡萄MET1基因的功能及对植物发育的影响,将葡萄VvMET1-1基因转入葡萄胚性愈伤组织和拟南芥中进行研究。本研究选择35S::VvMET1-1-GFP表达载体转入葡萄胚性愈伤组织后检测到明显的GFP信号,且该胚性愈伤组织能被成功诱导为体细胞胚,表明VvMET1-1首次被成功转入葡萄胚性愈伤组织中并且不影响胚性愈伤组织的发育和分化。VvMET1-1被转入拟南芥中发现,该基因能影响拟南芥叶片的长度和宽度,但是不影响植株形态和种子发育;转录组数据分析表明,许多逆境胁迫、生长素、种子萌发、果实成熟、脱落酸和茉莉酸合成相关的基因差异表达;甲基化组结果显示,拟南芥过表达VvMET1-1后CG和CHH位点甲基化水平分别发生了明显的上调和下调,且DNa.基化差异区(DMR)的类型主要是CG和CHH型,因此推测VvMET1-1可能通过调控DNa.基化水平的变化影响下游基因的表达,进而调控拟南芥的生长发育。
