Abstract
We recently described lack of phenotypic plasticity in reproductive organ development and substantial plasticity in vegetative organ development for the cycad Cycas micronesica. Is there an evo-devo explanation for the disparity in phenotypic plasticity of vegetative vs. reproductive organs? Despite modularity, might evolution of cycad phenology be controlled more by drift than selection?
摘要
我们最近描述了密克罗尼西亚苏铁在生殖器官发育中缺乏表型可塑性，而在营养器官发育中具有显著的可塑性。对于营养器官与生殖器官表型可塑性的差异，是否存在一个演化发育生物学的解释？尽管具有模块化特征，苏铁物候的演化是否可能更多地受随机漂变而非选择的控制？
