我们提出了以前引入的物理生长机制的重大进展研究,并将其与生化生长因子结合起来。所获得的结果使我们能够制定出支配所有生物有机体、它们的器官和系统的生长和进化发展的一般生长规律。人们发现,生长周期是由营养资源在维持需要和生物量生产之间的分配预先确定的。这种分布由生长率参数定量地定义,生长率参数取决于生物体的几何形状、生长阶段以及间接地取决于生物体的生化机制。产生的生物质的数量,反过来,定义了生化反应的组成。转移到生物量生产的营养物质的变化是迫使生物在整个生长和复制周期中进行的因素。其生长规律为:生长速率与养分流入量和生长比例成正比。考虑到不同生物的特定生化成分,我们找到所需养分的流入,并将其代入生长方程;然后计算了变形虫、野生型裂变酵母、裂变酵母突变体的生长曲线。在所有情况下,预测的生长曲线与实验数据非常吻合。所得结果证明了该发现的有效性和基础科学价值。

英文摘要:
  We present significantly advanced studies of the previously introduced physical growth mechanism and unite it with biochemical growth factors. Obtained results allowed formulating the general growth law which governs growth and evolutional development of all living organisms, their organs and systems. It was discovered that the growth cycle is predefined by the distribution of nutritional resources between maintenance needs and biomass production. This distribution is quantitatively defined by the growth ratio parameter, which depends on the geometry of an organism, phase of growth and, indirectly, organism's biochemical machinery. The amount of produced biomass, in turn, defines the composition of biochemical reactions. Changing amount of nutrients diverted to biomass production is what forces organisms to proceed through the whole growth and replication cycle. The growth law can be formulated as follows: the rate of growth is proportional to influx of nutrients and growth ratio. Considering specific biochemical components of different organisms, we find influxes of required nutrients and substitute them into the growth equation; then, we compute growth curves for amoeba, wild type fission yeast, fission yeast's mutant. In all cases, predicted growth curves correspond very well to experimental data. Obtained results prove validity and fundamental scientific value of the discovery.
