植物必须能够感知并响应在其整个生命周期中遇到的机械应力。 MScS-Like (MSL) 机械敏感离子通道家族是感知机械应力的一种机制。在玉米中，支撑根从土壤上方的茎节中伸出，有些保留在地上，而有些则生长到土壤中。我们测试了以下假设：地下支架根中的 MSL 基因表达高于地上支架根中的 MSL 基因表达。然而，两种环境之间的 MSL 表达没有差异。这项工作为更深入地了解玉米 MSL 基因表达和功能奠定了基础。
Plants must be able to sense and respond to mechanical stresses encountered throughout their lifespan. The MscS-Like (MSL) family of mechanosensitive ion channels is one mechanism to perceive mechanical stresses. In maize, brace roots emerge from stem nodes above the soil and some remain aerial while some grow into the soil. We tested the hypothesis that MSL gene expression is higher in subterranean brace roots compared to those that remain aerial. However, there was no difference in MSL expression between the two environments. This work sets the foundation for a deeper understanding of MSL gene expression and function in maize.
