The RhoA oncogene , have been revealed in recent years, are closely related to various malignant tumours. RhoA, belonging to Rho family, is one member of the ras superfamily, whose encoding production, namely RhoA protein, pertaining to micromolecular mass GTP conjugated protein family, in GTP conjunctive active form and GDP conjunctive unreactive form. It exist in the latter form in normal cells and the switch of the two forms enables them to educe functions, paralleling"molecular switch", the diminutive G protein in activated state being able to activate the wink dromo-iter to work functions, which is in the resemblance of process during which the Ras genic mutation induces its continous activations.

RhoA是近年来新发现的与多种恶性肿瘤密切相关的癌基因，RhoA属于Rho亚家族，是ras基因超家族的一员，其编码产物RhoA蛋白属于小分子量GTP结合蛋白族，分为GTP结合的活性型和GDP结合的非活性型两类，在正常细胞内以GDP结合的非活性型存在，两种活性形式之间的转换使他们能够发挥一种类似"分子开关"的作用，活性态的小G蛋白能激活下游的信号传导通路，行使其功能。

This paper presents a maximum criterion-based phylogeny analysis method for unrooted trees. To increase the confidence level of the derived evolutionary trees, we use bootstrapping and consensus analysis in conjunction with a genetic algorithm for crossover and mutation between evolutionary trees.

花瓣彩斑主要由基因突变或病毒入侵而形成。

The results showed that the changes of the types were not caused by new cell mutation, but by translocation of the different cell types of variegation. The changes of division direction of white cells and green cells resulted that some of the green epidermal cells translocated into the second layer and it pushed furthermore the origin white cells of the second layer into the third layer, so that the variegation altered.

Pollock'突变型异化不是由于细胞突变形成，而是由于质体突变型白色细胞和原型绿色细胞在生长发育过程中相互竞争转轨所致，即白色细胞和原型绿色细胞改变了分裂方向，部分表皮绿色细胞进人第二层，挤压第二层白色细胞转轨进人第三层，导致细胞类型的移位，从而形成异型斑。
