适应无处不在的重力场是推动地球陆生植物繁衍生息的根本基础。植物已经进化出一种非凡的能力，不仅使它们能够在地球的重力场中生存和发展，而且还使它们能够利用重力矢量来引导根和芽的生长，这一过程被称为向重力性。由重力刺激触发，植物向重力性是一个高度复杂的多步骤过程，需要许多细胞器和参与者以复杂的协调方式发挥作用。虽然这一过程已被研究了几百年，但仍有许多不清楚的地方，特别是早期事件，触发生长素外排载体PIN-形成（PIN）蛋白的重新定位，这可能导致生长素的不对称再分配。在过去的十年中，LAZY基因家族已被确定为一个关键的球员，确保生长素的适当重新分配和正常的热带反应的根和芽后重力刺激。LAZY蛋白似乎参与了重力信号的早期步骤，因为LAZY基因的突变一致地导致多种植物物种中生长素重新分布的改变。LAZY基因家族的鉴定和表征极大地促进了我们对植物向重力性的理解，并为研究向重力性早期事件的新分子细节开辟了新的前沿。在这里，我们回顾了目前的知识LAZY基因家族和LAZY蛋白调控的机制，控制根和芽向重力性。本文还讨论了LAZY基因家族在植物中的进化意义和保守性。
Adapting to the omnipresent gravitational field was a fundamental basis driving the flourishing of terrestrial plants on the Earth. Plants have evolved a remarkable capability that not only allows them to live and develop within the Earth’s gravity field, but it also enables them to use the gravity vector to guide the growth of roots and shoots, in a process known as gravitropism. Triggered by gravistimulation, plant gravitropism is a highly complex, multistep process that requires many organelles and players to function in an intricate coordinated way. Although this process has been studied for several 100 years, much remains unclear, particularly the early events that trigger the relocation of the auxin efflux carrier PIN-FORMED (PIN) proteins, which presumably leads to the asymmetrical redistribution of auxin. In the past decade, the LAZY gene family has been identified as a crucial player that ensures the proper redistribution of auxin and a normal tropic response for both roots and shoots upon gravistimulation. LAZY proteins appear to be participating in the early steps of gravity signaling, as the mutation of LAZY genes consistently leads to altered auxin redistribution in multiple plant species. The identification and characterization of the LAZY gene family have significantly advanced our understanding of plant gravitropism, and opened new frontiers of investigation into the novel molecular details of the early events of gravitropism. Here we review current knowledge of the LAZY gene family and the mechanism modulated by LAZY proteins for controlling both roots and shoots gravitropism. We also discuss the evolutionary significance and conservation of the LAZY gene family in plants.
