Atp-Independent Contractile Proteins From Plants, Michael Knoblauch, Gundula Noll, Torsten Müller, Dirk Prüfer, Ingrid Schneider-Hüther, Dörte Scharner, Aart Van Bel, Winfried Peters

Winfried S. Peters

This paper has no abstract; this is the first paragraph. Emerging technologies are creating increasing interest in smart materials that may serve as actuators in micro- and nanodevices. Mechanically active polymers currently studied include a variety of materials. ATP-driven motor proteins, the actuators of living cells, possess promising characteristics, but their dependence on strictly defined chemical environments can be disadvantagous. Natural proteins that deform reversibly by entropic mechanisms might serve as models for artificial contractile polypeptides with useful functionality, but they are rare. Protein bodies from sieve elements of higher plants provide a novel example. sieve elements form microfluidics systems …

Molecular Phylogenetics Of Neotropical Leafless Angraecinae (Orchidaceae): Re-Evaluation Of Generic Concepts, Barbara S. Carlsward, W. Mark Whitten, Morris H. Williams

Barbara S. Carlsward

Phylogenetic relationships of leafless Neotropical Angraecinae (Dendrophylax Rchb.f., Harrisella Fawc. & Rendle, Polyradicion Garay, and Campylocentrum Benth.) were estimated using combined nuclear (ITS nrDNA) and plastid (matK and trnL-F) data sets with African angraecoid taxa as outgroups. Results indicate that Harrisella, Polyradicion, and Campylocentrum filiforme (Sw.) Cogn. are embedded within Dendrophylax and should be included in Dendrophylax. This contrasts with earlier generic concepts, which have been based mainly on gross differences in floral size and various morphological autapomorphies. Based on our current sampling, Campylocentrum includes both leafy and leafless species and is sister to a broadly defined Dendrophylax.
