“…Co-expression of the HopE1-HA CaM-binding site mutants did not alter MAP65-1-GFP microtubule localization and did not significantly reduce the MAP65-1-GFP signal ( Figures 4A-4C and S4A). To determine if HopE1 has a more general effect on the microtubule network, we crossed the transgenic HopE1-expressing plants with plants that expressed MAP4-GFP, TUB6-GFP, TUA6-GFP, or EB1-GFP, other proteins associated with the microtubule network (Marc et al, 1998;Mathur et al, 2003;Nakamura et al, 2004;Takemoto et al, 2003). In contrast to MAP65-1-GFP, HopE1-HA had no effect on the fluorescence signal emanating from these GFP fusions ( Figures S4B-S4I).…”

The bacterial pathogen Pseudomonas syringae depends on effector proteins secreted by its type III secretion system for the pathogenesis of plants. The majority of these effector proteins are known suppressors of immunity, but their plant targets remain elusive. Using Arabidopsis thaliana as a model host, we report that the HopE1 effector uses the host calcium sensor, calmodulin (CaM), as a co-factor to target the microtubule-associated protein 65 (MAP65), an important component of the microtubule network. HopE1 interacted with MAP65 in a CaM-dependent manner, resulting in MAP65-GFP dissociation from microtubules. Transgenic Arabidopsis expressing HopE1 had reduced secretion of the immunity protein PR-1 compared to wild-type plants. Additionally, Arabidopsis map65-1 mutants were immune deficient and were more susceptible to P. syringae. Our results suggest a virulence strategy in which a pathogen effector is activated by host calmodulin to target MAP65 and the microtubule network, thereby inhibiting cell wall-based extracellular immunity.

“…Research work in the authors' laboratories has been extended to the use of the much cheaper carbon feedstocks for the production of carbon nanotube and graphene. This included the use of Jatropha oil [56], bituminous coal, super clean coal [57], Pongamia and palm oil [58], waste plastics [59], and presently even CO 2. The CNTs obtained were characterized and these were used for the production of nanocomposites by using polystyrene which showed interesting electrical and thermal properties.…”

In the present work, graphene was synthesized by catalytic reduction of carbon dioxide (dry ice) in presence of magnesium flame supported by zinc and nickel metal respectively. The use of Nickel resulted in the improvement of graphene yield. The multiwall carbon nanotubes (MWCNTs) were synthesized from pongamia oil in CVD setup. The synthesized graphene and MWCNTs were characterized by different characterization techniques such as scanning electron microscopy, transmission electron microscopy, Raman spectra and X‐ray diffraction study. Thus synthesized graphene and MWCNTs have been used as conductive filler in polystyrene (PS)/graphene and PS/MWCNT nanocomposites. PS nanocomposites were prepared by solution blending method using toluene as a solvent. The properties of PS/graphene nanocomposites were compared with those of PS/MWCNT nanocomposites and the graphene based nanocomposites showed improved results. Interestingly, PS/graphene nanocomposite showed good electrical conductivity (about ∼7.07 S/cm) and these also showed electromagnetic interference shielding effectiveness (–31 dB) with the loading of 10 wt% graphene in PS matrix. Thermal properties of PS/graphene nanocomposite were also studied and were found to be good. POLYM. COMPOS., 39:E1041–E1051, 2018. © 2017 Society of Plastics Engineers
