在天然林中，幼龄幼苗表现出与成年树木不同的季节生长模式。我们的特点，这种年龄依赖性的季节性生长的杨树的遗传和分子基础。我们展示了miR 156-SPL 3/5s模块在多年生树木中的调节方面，这与其在一年生植物中的机制非常不同。我们的研究揭示了天然林中不同年龄树木重要的气候适应、建立和生存策略的遗传机制。
Significance In natural forests, juvenile seedlings display different seasonal growth patterns to adult trees. We characterize the genetic and molecular base of this age-dependent seasonal growth in Populus trees. We show a regulatory aspect of the miR156-SPL3/5s module in perennial trees that is very different from its mechanism in annual plants. Our study reveals a genetic mechanism for an important climate adaptation, establishment, and survival strategy for trees of different ages in natural forests.
