Primary and lateral roots comprise root systems, which are vital to the growth and survival of plants. Several molecular mechanisms associated with primary and lateral root growth have been described, including some common regulatory factors for their initiation and development. However, in this opinion article, we discuss the distinct growth behavior of lateral roots in response to environmental cues, such as salinity, gravity, and nutrient availability, which are mediated via specific regulators. We propose that differential growth dynamics between primary and lateral roots are crucial for plants to adapt to the ever-changing environmental conditions.
主根和侧根构成了根系，对于植物的生长和存活至关重要。已经描述了与主根和侧根生长相关的几种分子机制，包括一些用于其起始和发育的共同调节因子。然而，在这篇观点文章中，我们讨论了侧根对环境信号（如盐度、重力和养分供应）的独特生长行为，这些信号是通过特定的调节剂介导的。我们提出，主根和侧根之间的差异生长动态对于植物适应不断变化的环境条件至关重要。
