Plant reproductive success depends on making fertile flowers but also upon developing appropriate shoot internodes that optimally arrange and support the flowering shoot. Compared to floral morphogenesis, we understand little about the networks directing internode growth during flowering. However, new studies reveal that long-range signals, local factors, and age-dependent micoRNA-networks are all important to harmonize internode morphogenesis with shoot development. Some of the same players modulate symplastic transport to seasonally regulate internode growth in perennial species. Exploring possible hierarchical control amongst symplastic continuity, age, systemic signals and local regulators during internode morphogenesis will help elucidate the mechanisms coordinating axial growth with the wider plant body.

继续前进-控制节点间的增长。

植物繁殖的成功取决于创造可育的花朵，还取决于发展合适的枝条节间，从而最佳地布置和支撑开花枝条。与花的形态发生相比，我们对开花期间指导节间生长的网络了解甚少。但是，新的研究表明，长距离信号，局部因素和年龄依赖性micoRNA网络对于协调节间形态发生与芽发育都非常重要。某些相同的参与者通过调节共生运输来季节性调节多年生物种的节间生长。探索节点间形态发生期间共生连续性，年龄，系统信号和局部调节剂之间可能的等级控制，将有助于阐明与较宽植物体协调轴向生长的机制。
