黑芥子细胞在其液泡中积累黑芥子酶，当组织受到食草动物损害时，催化有毒化合物的产生。芥子细胞位于脉管系统的远轴侧附近，但其起源尚不清楚。为了确定黑芥子细胞是否与血管前体细胞分化，我们产生了转基因拟南芥系，其表达黑芥子细胞报告基因以及3种血管前体细胞报告基因之一。黑芥子阳性细胞呈不连续分布，而血管前体阳性细胞呈连续分布。肌球蛋白和血管报告基因的荧光信号不重叠。此外，黑芥子阳性细胞的形状与血管前体阳性细胞的形状不同。这些结果表明肌球蛋白细胞的发育独立于脉管系统。
Myrosin cells accumulate myrosinases in their vacuoles to catalyze the production of toxic compounds when tissues are damaged by herbivores. Myrosin cells are positioned adjacent to the abaxial side of the vasculature but their origin is unclear. To determine whether the myrosin cells are differentiated from vascular precursor cells, we generated a transgenic Arabidopsis line that expressed a myrosin cell reporter together with one of 3 vascular precursor cell reporters. The myrosin-positive cells were discontinuously distributed while the vascular precursor-positive cells were continuously distributed. The fluorescent signals of the myosin and vascular reporters did not overlap. Furthermore, the shape of myrosin-positive cells was different from the shape of vascular precursor-positive cells. These results indicate that myosin cells develop independently of the vasculature.
