However, in comparison with animal tissues, relatively few plant cytoskeleton proteins have been identified. We presume this is not because the plant cytoskeleton is really made up of such few proteins, but rather that only rarely have attempts been made to identify plant-specific cytoskeleton proteins, using plant-specific methods. Here we outline methods that we have developed both for the isolation and identification of novel cytoskeleton proteins as well as for the visualization of novel filamentous structures in plant cells, and we describe several novel cytoskeleton proteins and two novel cytoskeleton structures, 'nanofilaments' and 'nanotubules'. We postulate that use of such approaches will lead to a rapid expansion of our knowledge of the plant cytoskeleton.}, number={2}, journal={PLANT SCIENCE}, author={Davies, E and Stankovic, B and Azama, K and Shibata, K and Abe, S}, year={2001}, month={Jan}, pages={185–196} }

Significant ATPase activity was present in the cytoskeleton fraction and this was eluted from the column at 0.6–0.7 M KOAc, in the same fractions as a 49-kDa protein (which we called B3). B3 was desalted and further purified by cation exchange column chromatography. Purified B3 catalyzed hydrolysis of ATP, CTP, GTP, TTP, UTP and ADP and thus appears to be an apyrase (ATP diphosphohydrolase, EC 3.6.1.5). Partial amino acid sequences of three major fragments were obtained by digestion of B3 by Staphylococcus aureus V8 protease (EC 3.4.21.19), and all these sequences were consistent with the previously reported amino acid sequences for pea nucleoside triphosphatase (NTPase, EC 3.6.1.15) (PIR S48859), which is thought to be an apyrase.}, number={12}, journal={PLANT PHYSIOLOGY AND BIOCHEMISTRY}, author={Shibata, K and Morita, Y and Abe, S and Stankovic, B and Davies, E}, year={1999}, month={Dec}, pages={881–888} }

The resulting electrical activity was monitored with extracellular electrodes. An electrical stimulus applied to the stem frequently evoked an action potential (AP), but never a variation potential (VP). In contrast, a heat-wound applied to a leaf virtually always elicited a VP, which was often accompanied by one or more superimposed spikes (putative APs). The kinetic parameters of the AP and the VP were investigated. The AP appears to propagate without decrement in velocity or magnitude, whereas the VP parameters decrease significantly with distance. The heat stimulus triggered rapid alterations in stem elongation/contraction, which preceded changes in electrical potential, indicating the transmission of a hydraulic signal. Light-off and light-on stimuli evoked negative- and positive-going changes in extracellular electrical potential, respectively, corresponding to de- and hyper-polarization of the plasma membrane. Membrane depolarization (extracellularly manifested as a VP) evoked by both the light-off and heat-wounding stimuli was able to trigger one or more APs. We interpret these results to suggest that APs are “genuine” electrical signals involving voltage-gated ion channels or pumps, which can be evoked directly by electrical stimulation or indirectly by changes in membrane potential occurring during the VP or after the light-off stimulus. In contrast, VPs appear to be a local (non-transmissible) electrical consequence of the passage of a rapidly transmitted hydraulic signal in the xylem, presumably acting on mechanosensitive ion channels or pumps in adjacent living cells.}, number={1}, journal={PHYSIOLOGIA PLANTARUM}, author={Stankovic, B and Witters, DL and Zawadzki, T and Davies, E}, year={1998}, month={May}, pages={51–58} }

The effects of stimulus withdrawal on gravitropic curvature were studied by following individual roots of cress (Lepidium sativum L.) through reorientation and clinostat rotation. Roots turned to the horizontal curved down 62 degrees and 88 degrees after 1 and 5 h, respectively. Subsequent rotation on a clinostat for 6 h resulted in root straightening through a loss of gravitropic curvature in older regions and through new growth becoming aligned closer to the prestimulus vertical. However, these roots did not return completely to the prestimulus vertical, indicating the retention of some gravitropic response. Clinostat rotation shifted the mean root angle -36 degrees closer to the prestimulus vertical, regardless of the duration of prior horizontal stimulation. Control roots (no horizontal stimulation) were slanted at various angles after clinostat rotation. These findings indicate that gravitropic curvature is not necessarily permanent, and that the root retains some commitment to its equilibrium orientation prior to gravitropic stimulation.}, number={3}, journal={PLANT PHYSIOLOGY}, author={Stankovic, B and Volkmann, D and Sack, FD}, year={1998}, month={Jul}, pages={893–900} }

The growth alterations were manifested as a transient increase in growth (petiole elongation), followed by a massive, long-lasting growth reduction. The electrical potential changes consisted of a wave of depolarization and re-polarization, i.e., a variation potential (VP). The tissue deformation apparently resulted from a pressure surge rapidly transmitted through the xylem, and preceded the changes in electrical potential. Externally-applied pressure mimicked flame wounding by triggering an electrical response resembling a VP. Our findings suggest that the VP results from a pressure surge in the xylem causing change in activity of mechanosensitive ion channels or pumps in adjacent living cells. The ensuing ion fluxes evoke plasma membrane depolarization, monitored extracellularly as a VP. Wounding also evoked a systemic decrease in polysomes, as well as a decrease in their protein synthesizing capacity in vitro. Very little of the newly-synthesized proteinase inhibitor (pin) and calmodulin (cal) mRNA was recruited into polysomes during the first hour following wounding. Since the VP appearance in distant tissue preceded the systemic molecular responses, the VP might be the long-distance signal up-regulating transcription of proteinase inhibitors and calmodulin, and down-regulating translation.}, number={3}, journal={PLANT AND CELL PHYSIOLOGY}, author={Stankovic, B and Davies, E}, year={1998}, month={Mar}, pages={268–274} }

We investigated the mechanism of occurrence and long-distance propagation of VP in sunflower (Helianthus annuus L.) plants. Here we present evidence of the relationship among injury-induced changes in xylem tension, turgor pressure, and electrical potential. Although locally applied wounding did trigger a change in membrane potential, it evoked even faster changes in tissue deformation, apparently resulting from pressure surges rapidly transmitted through the xylem and experienced throughout the plant. Externally applied pressure mimicked flame wounding by triggering an electrical response resembling VP. Our findings suggest that VP in sunflower is not a propagating change in electrical potential and not the consequence of chemicals transmitted via the xylem, affecting ligand-modulated ion channels. Instead, VP appears to result from the surge in pressure in the xylem causing a change in activity of mechanosensitive, stretch-responsive ion channels or pumps in adjacent, living cells. The ensuing ion flux evokes local plasma membrane depolarization, which is monitored extracellularly as VP.}, number={3}, journal={PLANT PHYSIOLOGY}, author={Stankovic, B and Zawadzki, T and Davies, E}, year={1997}, month={Nov}, pages={1083–1088} }
