开花植物在茎尖产生分生组织，其中特化组织在适当的时间产生茎顶端分生组织以分化成生殖结构、授粉并有效地产生种子。在开花分生组织的发育中达到顶点的一组复杂的分子和物候事件被称为“开花时间”。开花时间会影响植物的生产力，因为一旦开始开花的分子决定已经做出，植物就会将能量用于产生花朵和种子，而不是营养组织。因此，开花时间的开始是植物中的重要决定，特别是在包括作物的一年生植物中。人类将作物引入远离其原产地或自然生态系统的纬度和气候区域，在许多情况下需要修改本地开花时间。最近的分子遗传学研究揭示了与这种引进有关的遗传基础。本文综述了作物引种的最新进展及其遗传基础，以及其他农业植物在不同气候区的引种潜力。
Flowering plants produce a meristem at the shoot tip where specialized tissue generates shoot apical meristems at the appropriate time to differentiate into reproductive structures, pollinate and efficiently generate seeds. The complex set of molecular and phenological events culminating in development of a flowering meristem is referred to as ‘flowering time’. Flowering time affects plant productivity because plants dedicate energy to produce flowers and seeds rather than vegetative tissue once the molecular decision to initiate flowering has been taken. Thus, initiation of flowering time is an important decision in plants, especially in annual plants including crops. Humans have introduced crops into latitudes and climate areas far from their origin or natural ecosystem, requiring in many cases modification of native flowering times. Recent molecular–genetic studies shed light on the genetic basis related to such introductions. In this review, recent progress regarding crop introductions and their genetic bases are summarized, as well as the potential of other agricultural plants to be introduced into different climatic zones.
