Salt stress (SS) has become an important factor limiting afforestation programs. Because of their salt tolerance and fully sequenced genomes, poplars ( spp.) are used as model species to study SS mechanisms in trees. Here, we review recent insights into the physiological and molecular responses of to SS, including ion homeostasis and signaling pathways, such as the salt overly sensitive (SOS) and reactive oxygen species (ROS) pathways. We summarize the genes that can be targeted for the genetic improvement of salt tolerance and propose future research areas.
盐胁迫 (SS) 已成为限制造林计划的一个重要因素。由于杨树 ( spp.) 具有耐盐性和全基因组测序，因此被用作研究树木 SS 机制的模式物种。在这里，我们综述了近年来关于 对 SS 的生理和分子响应的新认识，包括离子稳态和信号通路，如盐过度敏感 (SOS) 和活性氧 (ROS) 途径。我们总结了可以作为提高耐盐性的遗传改良目标的基因，并提出了未来的研究领域。
