Abstract

Different plant species flower in different seasons, but there is also annual variability depending on environmental conditions. In this issue of Developmental Cell, Hyun et al. (2016) show that Arabidopsis plants can flower without proper seasonal cues if they have developed past the juvenile phase and have high levels of gibberellin.

摘要

不同的植物物种在不同的季节开花，但也会因环境条件的不同而有年度变化。在本期《发育细胞》中，Hyun 等人（2016）表明，如果拟南芥植物已经过了幼年期，并且具有高水平的赤霉素，即使没有适当的季节性提示，它们也可以开花。
