Cultivated strawberry (Fragaria x ananassa) is a globally important fruit crop which shows promise as a candidate for various methods of controlled environment production. However, a better understanding of the mechanisms of the regulation of flowering is needed, as more frequent or consistent flowering would be advantageous in controlled production. It is well understood that flowering in F. x ananassa responds to both photoperiod and temperature, however, the mechanism behind this response is not fully understood, particularly in perpetually flowering cultivars. While some genes of interest have been identified, a more complete model has not been established. This is largely due to the complexity of the octoploid genome and a lack of current knowledge on the mechanism of temperature response in both seasonal- and perpetual-flowering F. x ananassa. A starting point for developing a better model of flowering response in cultivated strawberries lies in the simpler Fragaria vesca, which indicates a FvCO-FvFT1-FvSOC1-FvTFL1 module for control of seasonal flowering and a lack of functional FvTFL1 responsible for perpetual flowering. However, there are some key differences when discussing F. x ananassa's perpetual flowering characteristics. Recent studies have helped to elucidate some of these differences, allowing for a putative model of seasonal flowering in F. x ananassa, as well as indicating where further questions need to be asked regarding perpetually flowering cultivars.

栽培草莓开花的环境和分子调控 （Fragaria x ananassa）


栽培草莓 （Fragaria x ananassa） 是一种全球重要的水果作物，有望成为各种受控环境生产方法的候选者。然而，需要更好地了解开花调节的机制，因为更频繁或一致的开花在受控生产中将是有利的。众所周知，F. x ananassa 的开花对光周期和温度都有反应，然而，这种反应背后的机制尚不完全清楚，尤其是在永久开花的品种中。虽然已经确定了一些感兴趣的基因，但尚未建立更完整的模型。这主要是由于章鱼基因组的复杂性以及目前缺乏关于季节性和永久开花 F. x ananassa 温度响应机制的知识。在栽培草莓中开发更好的开花反应模型的起点在于更简单的 Fragaria vesca，这表明 FvCO-FvFT1-FvSOC1-FvTFL1 模块用于控制季节性开花和缺乏负责永久开花的功能性 FvTFL1。然而，在讨论 F. x annassa 的永久开花特性时，存在一些关键差异。最近的研究有助于阐明其中一些差异，从而可以建立一个推定的 F. x ananassa 季节性开花模型，并指出需要对永久开花的栽培品种提出进一步的问题。
