Many new questions on the regulation of shoot branching have been raised in recent years, prompting a review and reassessment of the role of each signal involved. Sugars and their signaling networks have been attributed a major role in the early events of axillary bud outgrowth, whereas cytokinin appears to play a critical role in the modulation of this process in response to the environment. Perception of the recently discovered hormone strigolactone is now quite well understood, while the downstream targets remain largely unknown. Recent literature has highlighted that auxin export from a bud is important for its subsequent growth.
近年来,关于 shoot branching 调控的许多新问题被提出,促使人们对涉及的每个信号的作用进行了回顾和重新评估。糖及其信号网络被认为在侧芽生长的早期事件中起主要作用,而细胞分裂素似乎在响应环境对该过程的调节中起关键作用。对最近发现的激素独脚金内酯的感知现在已经相当清楚,而下游靶标仍然很大程度上未知。最近的文献强调了从芽中输出的生长素对于其后续生长的重要性。
