Abstract

The architectural mathematical model Greenlab was tested for assisting plant phenotyping on two rice genotypes: Nippon Bare (NB) and Phyllo, its organogenesis mutant. A 50 days experiment was realized to compare, at organ level on NB, tiller pruned NB and Phyllo, morphogenesis, sugar partitioning and assimilation rate. Phenotypic data were used to optimize Greenlab parameters, considered then as process based traits. Experimental analysis showed weak modifications of pruned rice morphogenesis occurred. In contrast, Phyllo showed quicker organogenesis, small organs, no tillering, half the assimilation rate of NB, modified root sugar metabolism. Greenlab fittings on observations were good except for NB, mainly because of the difficulty of correctly optimizing numerous small leaf sinks (generated by process) compared to a single big root sink compartment. However, Greenlab successfully sensed the phenotypic differences underlined experimentally, in particular, modified carbon sink to source relationships for Phyllo. Modeling analysis of rice tillering cases shows that Greenlab has a great potential as heuristic approaches to be applied to plant phenotyping, more case studies are proposed to testing the model as a suitable tool to assist to screen plant phenotype.
利用Greenlab模型辅助分析水稻形态发生&以叶突变体及其野生型“日本裸”为例
利用建筑数学模型Greenlab对两种水稻基因型(Nippon Bare, NB)及其器官发生突变体Phyllo进行了表型分析。通过50 d的试验,在器官水平上比较NB、分蘖修剪后的NB和Phyllo的形态发生、糖分配和同化速率。表型数据被用来优化Greenlab参数,然后被认为是基于过程的性状。实验分析表明,修剪后的水稻形态发生了弱修饰。相比之下,叶果器官发生更快,器官小,不分蘖,NB同化率为一半,根糖代谢改变。除了NB之外,Greenlab的观测结果都很好,主要是因为与单个大的根汇区相比,正确优化许多小的叶汇(由过程产生)很困难。然而,Greenlab成功地检测到了实验中强调的表型差异,特别是修改了菲洛的碳汇源关系。水稻分蘖案例的建模分析表明,Greenlab作为一种启发式方法具有很大的潜力,可以应用于植物表型分析,并提出更多的案例研究来验证该模型作为辅助筛选植物表型的合适工具。
