9603956 Ortega真菌孢子囊体是易于操作的大的单细胞，其生长受外部因素如光和温度的影响。 这些细胞代表了研究单细胞发育的理想系统。 Ortega博士是一位生物药理学家，他通过一组参数描述了这些细胞的生长，得出了一组“扩增生长方程”，然后通过压力探针测量进行了研究。 该建议集中在阐明的机制，控制螺旋生长的伸长孢子囊。 这项工作包括生长过程中的压力探针测量，以及微纤维取向和纤维滑动的分析。 这项工作是强烈的数学模型的基础上，主要依靠实验数据来衡量理论考虑的准确性。 这项工作的价值在于分析了一个简单的模型系统，可以为植物细胞更复杂的细胞壁生长特性提供模型。

9603956 Ortega The growth of fungal sporangiophores, large single cells that are amenable to manipulation, is influenced by external factors, for example light and temperature. These cells represent an ideal system to study single cell development. Dr. Ortega is a biophysicist and has described the growth of these cells by a set of parameters, resulting in a set of "augmented growth equations" which were then studied by pressure probe measurements. The proposal concentrates on the elucidation of mechanisms that control helical growth of elongating sporangiophores. The work includes pressure probe measurements during growth, and analysis of microfibril orientation and slippage of fibrils. The work is strongly based on mathematical models and relies on experimental data mainly to gauge the veracity of theoretical considerations. The value of the work lies in the analysis of a simple model system that can provide a model for the more complex cell wall growth characteristics of plant cells.
