چکیده
Stomata are essential for plant productivity but the genes required for the terminal specification of the stomatal fate are largely unknown. Mutations in the Arabidopsis FOUR LIPS locus, an R2R3 MYB transcription factor, produce clusters of stomata in direct contact. The clusters result from a delay in cell cycle exit and in guard cell specification. In addition to the MYB domain, FLP contains a coiled-coil domain likely involved in protein-protein interaction. To identify putative FLP interacting partners, yeast two-hybrid experiments were carried out. In work in progress, two positive FLP partners have been identified from Arabidopsis cDNA library. One encodes an unknown protein containing four coiled-coil domains, and the other encodes a DnaJ domain-containing protein. The coiled-coil domain in FLP is responsible for the interaction with these two partners. The MYB domain in FLP is also involved in the interaction with the DnaJ domain-containing protein. Biochemical and genetic approaches are currently being pursued to validate the identity of these two proteins as FLP partners and to investigate their participation in the stomata regulatory network

Dephosphorylation of the Core Septin, AspB, in a Protein Phosphatase 2A-Dependent Manner Impacts Its Localization and Function in the Fungal Pathogen Aspergillus fumigatus
Septins are a conserved family of GTPases that form hetero-oligomeric complexes and perform diverse functions in higher eukaryotes, excluding plants. Our previous studies in the human fungal pathogen Aspergillus fumigatus revealed that the core septin, AspB, a CDC3 ortholog, is required for septation, conidiation, and conidial cell wall organization. Although AspB is important for these cellula...
متن کاملImproving Electrical Conductivity, Thermal Stability, and Solubility of Polyaniline-Polypyrrole Nanocomposite by Doping with Anionic Spherical Polyelectrolyte Brushes
The extent to which anionic spherical polyelectrolyte brushes (ASPB) as dopant improved the performance of polyaniline-polypyrrole (PANI-PPy) nanocomposite was investigated. Different characterization and analytical methods including Fourier transform infrared spectroscopy (FTIR), thermo-gravimetric analysis (TGA), scanning electron microscopy (SEM), and X-ray diffraction (XRD) confirmed that A...

The procedures for the synthesis of polypyrrole (PPy) doped with anionic spherical polyelectrolyte brushes (ASPB) (PPy/ASPB nanocomposite) by means of in situ chemical oxidative polymerization were presented. Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopic analysis suggested the bonding structure of PPy/ASPB nanocomposite. Scanning electron microscopy (SEM) was used to co...
متن کاملThe septin AspB in Aspergillus nidulans forms bars and filaments and plays roles in growth emergence and conidiation.
In yeast, septins form rings at the mother-bud neck and function as diffusion barriers. In animals, septins form filaments that can colocalize with other cytoskeletal elements. In the filamentous fungus Aspergillus nidulans there are five septin genes, aspA (an ortholog of Saccharomyces cerevisiae CDC11), aspB (an ortholog of S. cerevisiae CDC3), aspC (an ortholog of S. cerevisiae CDC12), aspD ...
