植物特异性YABBY基因最初被定义为它们在真双子叶植物侧部器官中决定远轴/近轴细胞命运以及在分化组织如叶中抑制分生组织基因的作用。在拟南芥中，FILAMENTOUS FLOWER（FIL）也是花序和花分生组织建立以及花发育所必需的，其途径涉及花转变和身份基因。在这里，我们描述了一个FIL的直向同源物的基础真双子叶植物，罂粟（罂粟）的表征，并展示了在图案的高度裂叶的罂粟的基因的作用。使用病毒诱导的基因沉默沉默PapsFIL导致叶片层流面积减少，边缘锯齿更明显，在某些情况下，叶分叉。相比之下，该基因似乎不会影响花的发育，这些功能的变化进行了讨论，其分类位置作为一个基础真双子叶植物和其确定的生长习性。
The plant-specific YABBY genes were initially defined by their roles in determining abaxial/adaxial cell fate in lateral organs of eudicots, and repressing meristematic genes in differentiating tissues such as leaves. In Arabidopsis thaliana FILAMENTOUS FLOWER (FIL) is also required for inflorescence and floral meristem establishment and flower development in a pathway involving the floral transition and identity genes. Here we describe the characterization of a FIL orthologue from the basal eudicot, Papaver somniferum (the opium poppy), and demonstrate a role for the gene in patterning the highly lobed leaf of the poppy. Silencing of PapsFIL using viral-induced gene silencing resulted in leaves of reduced laminar area, more pronounced margin serration and, in some cases, leaf bifurcation. In contrast, the gene does not appear to affect the development of the flower, and these variations in function are discussed in relation to its taxonomic position as a basal eudicot and its determinate growth habit.
