马铃薯块茎生命周期的控制多年来一直是人们感兴趣的课题。已经采用了许多不同的方法，并且可以获得有关块茎生命周期中发生的激素，代谢和基因表达变化的数据。尽管付出了巨大的努力，但控制马铃薯块茎生命周期的统一模型尚未出现。我们利用生理、生化和细胞生物学技术对块茎的生命周期进行了详细的分析。研究表明，块茎诱导和休眠打破的一个主要因素是控制资源分配给分生组织或营养组织的共塑门控。未来的挑战包括在分子水平上确定调节共塑门控的因素，并将这些发现外推到其他系统。
The control of the potato tuber life cycle has been the subject of significant interest over many years. A number of different approaches have been adopted and data is available regarding hormonal, metabolic and gene expression changes that occur over the tuber life cycle. Despite this intense effort, no unifying model for the control of the potato tuber life cycle has emerged. We have undertaken a detailed analysis of the tuber life cycle utilising physiological, biochemical and cell-biological techniques. It has emerged that a major factor contributing to both tuber induction and dormancy break is symplastic gating which controls the allocation of resources to meristematic or vegetative tissues. Future challenges include the determination of factors regulating symplastic gating at the molecular level and the extrapolation of these findings to other systems.
