Plant Physiology封面故事系列之二（2020年第2期封面)：Plant architecture contributes to winter hardiness

2020年2月plant physiology 封面展示了模式生物二穗短柄草在秋季的表型。在秋天，二穗短柄草植株结构相对于夏季长的非常浓密（densely and close），分支和叶片增加可以帮助其冠层相对隔离，这对于其越冬有帮助。导致二穗短柄草株型改变的基因是与开花相关的基因VERNALIZATION1 (VRN1)。

On the Cover: During the autumn, the model grass Brachypodium distachyon grows densely and close, unlike its tall form familiar to growers in the summer months. The accumulated branches and leaves of the dense growth may help to insulate its crown tissues and contribute to the over-wintering survival of the plant. Mayer et al. find that this growth transition is influenced by the flowering gene VERNALIZATION1 (VRN1). Image credit: Boris F. Mayer.
