Cellular Functions

In Mimosa pudica L., the geotropic movement (a slow variety of leaf movement) induced by inverting plants in the gravific field is reversibly inhibited by diethyloxide used in a range of concentrations producing, reversibly, in the same plant, inhibition of the seismonastic leaf movement (a quick variety of leaf movement) and in other organisms, inhibition of various cellular functions such as photosynthesis, caryocinesis, and bacterial luminescence.The degree of inhibition of geotropic leaf movement is dependent upon the concentration of ether, the duration of etherization, the time of anaesthetic admission, and the sequence of the motor organs. Results led to the following conclusions: preliminary etherization of plants, in vertical position, decreases rate of the geotropic movement; etherization occurring during the course of this movement can stop it in certain conditions; geotropic movement is more inhibitedin primary than in secondary motor organs, whereas the opposite occurs in seismonastic movement.The discussion deals with the contribution of these results to the knowledge of leaf geotropism.

Naturally Occurring

Cyclic mononucleotides − 2′,3′ cAMP and 2′,3′ cGMP − were found in several higher plants. They seem to be widespread, naturally occurring compounds. 2′ AMP, 3′ AMP, 2′ GMP and 3′ GMP, which were also isolated from several plants, are possibly artifacts of the cyclic nucleo­tides. In small amounts ApA was isolated from Abutilon grandiflorum, UpA and UpG from Mimosa pudica L.The biological influence of 2′,3′ cAMP and 2′,3′ cGMP on the nyctinastic leaf movement was tested. There is some evidence that both substances shift and dampen the circadian rhythm of Albizia lophanta.

Assay Time

A small number of species, including Mimosa pudica, use rapid leaf movement as a presumptive defensive strategy. How movement-based defenses change in response to mechanical damage and whether changes are localized or systemic is unknown. This is in contrast to a substantial literature describing how mechanical leaf damage can cause morphological and chemical responses within a diversity of plant species. Depending on the species and the stimuli, these chemical and morphological responses can be localized to the tissues damaged or systemic throughout the plant body. Here we report the results of a small experiment designed to test the following: (i) whether mechanical leaf damage influences subsequent leaf closure behavior, and (ii) whether changes were systemic or localized. To do this, we scored leaves using a behavioral assay (time-to-reopen leaves following a subsequent touch stimuli) for several days before and following mechanical damage. Leaves above and below the damaged leaf were observed, on damaged and undamaged plants, allowing us to assess whether any change was systemic. We found leaf damage caused strong localized effects, greatly increasing the time-to-reopen of the damaged, but not adjacent, leaves. Neither the physiological cause nor fitness consequences of this behavioral shift are known. Interestingly, this altered behavior resulted in damaged leaves remaining “hidden” longer than undamaged leaves. If leaf closure reduces risk of herbivory, there could be adaptive value, analogous to inducible chemical and morphological defenses.
