“…The facts that the uncommitted primordium has a similar structure to the shoot apical meristem (SAM) (except it has determinate growth), and tendril meristems can produce rudimentary leaves with axillary buds that may develop into new tendrils in the same way that new branches arise from the leaf axillary meristem, suggest that tendrils from Vitaceae are modified extra‐axillary branches (Tucker & Hoefert, ; Shah & Dave, ; Table ). However, the GA‐insensitive V. vinifera mutant, which produces inflorescences along the length of its shoot in place of tendrils, and the fact that in Parthenocissus and Vitis some meristems that usually would produce tendrils can sometimes produce inflorescences instead (Millington, ; Carmona et al ., ), suggest that the grapevine tendril is a modified inflorescence (Boss & Thomas, ).…”

The climbing habit has evolved multiple times during the evolutionary history of angiosperms. Plants evolved various strategies for climbing, such as twining stems, tendrils and hooks. Tendrils are threadlike organs with the ability to twine around other structures through helical growth; they may be derived from a variety of structures, such as branches, leaflets and inflorescences. The genetic capacity to grow as a tendrilled climber existed in some of the earliest land plants; however, the underlying molecular basis of tendril development has been studied in only a few taxa. Here, we summarize what is known about the molecular basis of tendril development in model and candidate model species from key tendrilled families, that is, Fabaceae, Vitaceae, Cucurbitaceae, Passifloraceae and Bignoniaceae. Studies on tendril molecular genetics and development show the molecular basis of tendril formation and ontogenesis is diverse, even when tendrils have the same ontogenetic origin, for example leaflet-derived tendrils in Fabaceae and Bignoniaceae. Interestingly, all tendrils perform helical growth during contact-induced coiling, indicating that such ability is not correlated with their ontogenetic origin or phylogenetic history. Whether the same genetic networks are involved during helical growth in diverse tendrils still remains to be investigated.

“…con el tiempo, el zarcillo se lignifica y se liberan enzimas que lo tornan resistente a la intemperie. Los zarcillos que quedan sin adherirse no se contraen, se marchitan y caen (Bowling & Vaughn, 2008;He et al, 2010He et al, , 2011Jiang, 1994;Junker, 1976;Shah & dave, 1970;Steinbrecher et al, 2011).…”

“…The lianas exhibit four patterns based on the presence or absence of tendril/inflorescences and axillary buds. Leaf-opposed tendril/inflorescences are categorized as "intermittent" (Tucker and Hoefert 1968;Shah and Dave 1970) or "interrupted" (Gerrath et al 1998) if they are present at two of three nodes, as in patterns 2, 3, and 4 ( fig. 1B, 1C, and 1D, respectively).…”

The relationship between two of the more commonly occurring patterns and their primary vasculature was examined. Cissus alata was chosen to represent pattern 5 (distichous phyllotaxy and continuous leaf-opposed tendril/inflorescences) and Vitis riparia to represent pattern 4 (distichous phyllotaxy and a three-node modular pattern of interrupted leaf-opposed tendril/inflorescences). Both species show architectural dorsiventrality in that the prophyll of the first-order axillary bud is ventral and vascular dorsiventrality in that all midvein leaf traces arise from ventral vascular sympodia. Both taxa have an even number of vascular sympodia, with four in C. alata and six in V. riparia. Leaf traces are multilacunar, with seven traces in C. alata and five in V. riparia. The leaf-opposed tendril/inflorescences have the same vascular architecture as the axillary buds and are derived from the same vascular sympodia, although there is no evidence from this study that the tendrils represent a vertically displaced serial axillary bud. Vascular architecture reflects the underlying three-node modularity of these shoot patterns in two ways: first, leaf traces in both species most commonly arise three nodes below their point of departure from the stem, and second, the number of internodes the axillary bud traces traverse is dependent on the position of the tendril within the shoot module in V. riparia (pattern 4). Vegetative characters such as shoot architecture and primary vascular pattern should prove useful in phylogenetic analyses of this architecturally unique family.
