phyllome adaxial meristem

Term Information

plant anatomy
narrow: phyllome adaxial rounding meristem
narrow: phyllome adaxial unifacial meristem
exact: フィロム向軸側分裂組織 (Japanese)
exact: meristema adaxial del filoma (Spanish)
A portion of meristem tissue (PO:0009013) that is found on the adaxial side of a developing phyllome (PO:0006001). [source: POC:curators]
Contributes to the thickness of a phyllome (PO:0006001). There are two types of adaxial meristems. In phyllomes with a petiole (PO:0020038) and lamina (PO:0025060), an adaxial rounding meristem occurs later in development, is separated from the apical meristem (PO:0020144), and contributes to the thickness of the petiole and midrib. In unifacial phyllomes, the an adaxial meristem occurs earlier in development, is close to but separate from the apical meristem, and contributes to the thickness and cross-sectional shape of the entire phyllome. If annotating to a leaf, use the more specific term leaf adaxial meristem (PO:0025401).
