Recent collections near Mt Anne in southwestern Tasmania have extended the known range of the previo...

Cell-to-cell junction structures play a key role in cell growth rate control and cell polarization. In endothelial cells (EC), these structures are also involved in regulation of vascular permeability and leukocyte extravasation. To identify novel components in EC intercellular junctions, mAbs against these cells were produced and selected using a morphological screening by immunofluorescence m...

Evolution of the chloroplast from an endosymbiont to an organelle involved the transfer of many genes and regulatory functions to the nucleus, as well as a shift from mainly regulating the initiation of transcription to regulating additional, posttranscriptional steps (reviewed in Barkan, 2011). Sequence-specific RNA binding proteins, such as pentatricopeptide repeat (PPR) proteins, have signif...

The rate of synthesis of cytochrome f is decreased approximately 10-fold when it does not assemble with the other subunits of the cytochrome b(6)f complex in Chlamydomonas reinhardtii chloroplasts. This assembly-mediated regulation of cytochrome f synthesis corresponds to a regulation of petA mRNA initiation of translation. Here, we demonstrate that cytochrome f translation is autoregulated by ...

Photopolymerizable and degradable biomaterials are becoming important in the development of advanced materials in the fields of tissue engineering, drug delivery, and microdevices. We have recently developed a library of poly(beta-amino ester)s (PBAEs) that form networks with a wide range of mechanical properties and degradation rates that are controlled by simple alterations in the macromer mo...
