While math has long been used to describe plant patterns (e.g. the Fibonacci numbers observed in lateral organ arrangements, such as in pine cones), recent developments in molecular imaging have spurred a growing recognition in biology that many aspects of plant development are inherently quantitative (such as organ spacing, plant shape and architecture) and require mathematical theory to explain the underlying molecular mechanisms. Much of the new quantitative and mathematical work has been on the spatial distribution of the hormone auxin (a primary determinant of local growth) in the model plant

虽然数学长期以来一直被用来描述植物模式（例如在横向器官排列中观察到的斐波那契数，如在松果中），但分子成像的最新发展促使生物学越来越认识到植物发育的许多方面本质上是定量的（如器官间距，植物形状和结构），需要数学理论来解释潜在的分子机制。许多新的定量和数学工作都是在模型植物中激素生长素（局部生长的主要决定因素）的空间分布上进行的
