In addition to its role in protein synthesis and the plant cells' response to environmental stresses, circumstantial evidence suggest that proline may also play a role in flowering and development both as a metabolite and as a signal molecule. Although there is a growing consensus that proline is of special importance throughout the reproductive phase (from flower transition to seed development) a general agreement on the molecular and genetic mechanisms proline is involved in, is yet to be established. In this paper we shall review and critically discuss most of the evidence supporting a role for proline in plant development, paying special attention to the recently reported role of proline in flower transition.
除了在蛋白质合成和植物细胞对环境胁迫的反应中发挥作用外，间接证据表明脯氨酸作为代谢物和信号分子，也可能在开花和发育中发挥作用。尽管越来越多的人认为脯氨酸在整个生殖阶段（从花的转变到种子发育）都具有特殊的重要性，但对于脯氨酸参与的分子和遗传机制，尚未达成普遍共识。在本文中，我们将回顾和批判性地讨论大多数支持脯氨酸在植物发育中发挥作用的证据，特别关注最近报道的脯氨酸在花转变中的作用。
