“…This phenomenon granted protection against herbivores by promoting the association with nurse plants (cacti and thorny shrubs); interestingly, such induction of tendril-like stems following damage only occurred in the shade, which is a cue of the presence of the nurse plant ( González-Teuber and Gianoli 2008 ). Induced twining was also observed in I. purpurea after subjecting plants to folivory by snails as well as to exposure to conspecific volatiles (released from ground leaves) ( Atala et al . 2014 ).…”

Climbing plants require an external support to grow vertically and thus achieve better access to sunlight. Climbing plants that find a suitable support have greater performance, size and reproduction than those that remain prostrate. Plant behaviour involves rapid morphological or physiological responses to events or environmental changes. Theoretical frameworks from behavioural ecology, traditionally applied to animals, have been successfully used to study plant behaviour. I herein review studies addressing ecological causes and consequences of support finding and use by climbing plants. I also propose the use of behavioural ecology theoretical frameworks to study climbing plant behaviour.

“…The tendrils might be able to sense the properties of the stimuli via chemical cues. In this respect it is well known that some plants use volatile blends to locate several host plants 52,53 . Furthermore, recent literature, using modern analytical techniques to visualise the chemical environment of plants, has unravelled mechanisms of plant-environment interaction that might serve to adapt to an ever-changing environment 49 .…”

Although plants are essentially sessile in nature, these organisms are very much in tune with their environment and are capable of a variety of movements. This may come as a surprise to many non-botanists, but not to Charles Darwin, who reported that plants do produce movements. Following Darwin’s specific interest on climbing plants, this paper will focus on the attachment mechanisms by the tendrils. We draw attention to an unsolved problem in available literature: whether during the approach phase the tendrils of climbing plants consider the structure of the support they intend to grasp and plan the movement accordingly ahead of time. Here we report the first empirical evidence that this might be the case. The three-dimensional (3D) kinematic analysis of a climbing plant (Pisum sativum L.) demonstrates that the plant not only perceives the support, but it scales the kinematics of tendrils’ aperture according to its thickness. When the same support is represented in two-dimensions (2D), and thus unclimbable, there is no evidence for such scaling. In these circumstances the tendrils’ kinematics resemble those observed for the condition in which no support was offered. We discuss these data in light of the evidence suggesting that plants are equipped with sensory mechanisms able to provide the necessary information to plan and control a movement.

“…Rather, it appears that the [15]. The twining response of Convolvulus arvensis is induced by the volatile cues from injured conspecific leaves [28,29]. These studies implies the importance of the volatile cues on the avoiding response of the tendrils of C. japonica to conspecifics.…”

Movement and growth habit of climbing plants have attracted attention since the time of Charles Darwin; however, there are no reports on whether plants can choose suitable hosts or avoid unsuitable ones based on chemoreception. Here, I show that the tendrils of Cayratia japonica (Vitaceae) appear to avoid conspecific leaves using contact chemoreception for oxalates, which are highly concentrated in C. japonica leaves. The coiling experiments show that C. japonica has a flexible plastic response to avoid coiling around conspecific leaves. The coiling response is negatively correlated with the oxalate content in the contacted leaves. Experiments using laboratory chemicals indicate that the tendrils avoid oxalate-coated plastic sticks. These results indicate that the tendrils of C. japonica avoid coiling around a conspecific leaf based on contact chemoreception for oxalate compounds. The tendrils of climbing plants may function as a chemoreceptor system to detect the chemical cues of a contacted plant.
