摘要
禾本科植物叶的形态发育在细胞尺度上遵循着严格的动力学规律,其在环境影响下的可塑性是禾本科植物叶片环境适应性的细胞学基础。近年来,禾本科植物叶形态发育的动力学分析方法已经成为植物生长发育及环境适应性研究中一类重要的辅助研究工具。简介了禾本科植物多阶段动力学模型的一般建模思想,并结合国外研究现状,从植物叶形态发育可塑性的角度简短分析了环境影响下禾本科植物叶发育适应性过程中宏观与微观尺度下的动力学机制,有望对国内今后开展该领域的研究提供有益的参考作用。
Plants vary widely under different environmental conditions.A general kinematic framework of grass leaf growth between different species or genotypes that is variable or has plasticity under different conditions is an important approach to better understanding plant plasticity at the organ level,tissue level,and/or cellular level.The identity of the components of multi-phase kinetic models depends on theoretical considerations that allow reinterpretation during leaf growth processes,as well as growth between subsequent leaves,tiller production and whole-plant growth.During recent decades,physiological and morphological aspects of the kinetic approach provide a series of acute quantitative analyses to investigate the relationship between the regulation of molecular mechanisms and macroscopic results during grass leaf growth.This review introduces multi-phase kinematic models as a new perspective in determining variation in grass leaf growth.The growth plasticity of grass leaves from a multi-phase kinematic perspective is discussed together with its role in some molecular regulations and further potential for molecular biology and grass science of the kinematic modeling approach.
