When observing grape shoots, tendrils are attached opposite the leaves (Gerrath and Posluszny 2007, \u9091\u7530\u3068\u524d\u7530 2022). This attachment pattern of tendrils is not observed in other angiosperms and is common to all tendril-producing species in the grape family (Vitaceae, Wen 2007). Therefore, it is considered a synapomorphy of the Vitaceae.<\/p>\n\n\n\n

From epi-illumination light microscopy and scanning electron microscopy of the shoot apical meristem and light microscopy of the sections in ten species across four genera of the Vitaceae (Ampelopsis<\/em>, Cissus<\/em>, Parthenocissus<\/em>, and Vitis<\/em>) (Bugnon 1964, Millington 1966, Tucker and Hoefert 1968, Shah and Dave 1970, Gerrath and Posluszny 1988, Gerrath and Posluszny 1989a, Gerrath and Posluszny 1989b, Gerrath and Posluszny 1994, Wilson and Posluszny 2003, Gerrath and Posluszny 2007, Timmons et al. 2007), it has been found that the original shoot apical meristem is maintained, and the axillary meristem forms the tendril primordium (reviewed in Gerrath and Posluszny 2007). This type of growth is called monopodial branching, which is the same branching pattern observed during the vegetative growth phase of Arabidopsis thaliana<\/em>. While the stem of Arabidopsis does not elongate, in other angiosperms like tobacco, the region between the axillary meristem and the next leaf primordium elongates. The unique characteristic of the Vitaceae is that the tissue (yellow part in the figure) between the axillary meristem (Tendril primordium) and the primordium of subtending leaf (L2 in the figure) elongates, positioning the tendril opposite the next leaf primordium (L1). Therefore, it is considered that the tendril arrangement opposite the leaves, which is a unique trait of the Vitaceae, evolved through anisotrophic stem growth.<\/p>\n\n\n\n

On the other hand, in Rhoicissus digitata<\/em>, it has been reported that, at the shoot apex when the tendril primordium forms, the tendril primordium is larger than the shoot apical meristem, suggesting that the original shoot apical meristem transforms into the tendril primordium, and the axillary meristem of L1 forms a new shoot apical meristem (referred to as sympodial branching) (Gerrath et al. 1998, Gerrath and Posluszny 2007). In the related species R. rhomboidea<\/em>, the shoot apical meristem and the tendril primordium are almost the same size (Gerrath et al. 1998, Gerrath and Posluszny 2007). In Arabidopsis thaliana<\/em> and rice, different sets of genes are expressed at the shoot apical meristem and the initial stage of axillary meristem formation (reviewd in Wang and Jiao 2018, Nicolas and Laufs 2022), and by investigating the gene expression patterns over developmental stages, it is possible to determine the boundary between the shoot apex and the axillary bud and to investigate whether a transformation from shoot apical meristem to axillary meristem is occurring. By combining studies of traditional external morphology and cell morphology in sections with gene expression patterns, it would become clearer how tendrils in the Vitaceae are formed.<\/p>\n\n\n\n
