Whether sucrose catabolism in Arabidopsis requires INVs rather than SUSs, or 2 closely related isoforms of neutral INV predicted to be the main cytosolic forms in the root, is generated.
The potyvirus recessive resistance gene, sbm1, identifies a novel role for translation initiation factor eIF4E in cell-to-cell trafficking.

Protein expression and cap-binding analysis showed that eIF4E encoded by a resistant plant could not bind to m7G-Sepharose, a result which may point to functional redundancy between eIF 4E and the paralogous eIF(iso)4E in resistant peas, providing a more complete picture of the potyvirus life cycle.

An epigenetic model of PTGS in which transgene methylation is associated with an RNA–DNA interaction that ensures that PTGS is maintained is supported.

A new family of plasmodesmata-located proteins whose members have the features of type I membrane receptor-like proteins that affect cell-to-cell communication are identified and exhibit a mode of intracellular trafficking and targeting novel for plant biology.

Three closely related members of a larger family of X8 domain–containing proteins that targeted to Pds are identified, two of which specifically bind to 1,3-β-glucans (callose) in vitro and are named Pd callose binding proteins (PDCBs).
Turnip crinkle virus coat protein mediates suppression of RNA silencing in Nicotiana benthamiana.
Remorin, a Solanaceae Protein Resident in Membrane Rafts and Plasmodesmata, Impairs Potato virus X Movement[W]
It is shown that REM can interact physically with the movement protein TRIPLE GENE BLOCK PROTEIN1 from PVX and the potential for lipid rafts to act as functional components in plasmodesmata and the plasma membrane is discussed.
Arabidopsis Plasmodesmal Proteome
The proteomic analysis of plasmodesmata purified from the walls of Arabidopsis suspension cells suggests that the membranous elements in plasmodemata may be rich in receptor-like functions, and validate the content of the PD-proteome as a valuable resource for the further uncovering of the structure and function of plASMata as key components in cell-to-cell communication in plants.
Arabidopsis cell wall proteome defined using multidimensional protein identification technology
MudPIT was used to analyse the ‘tightly‐bound’ proteome for purified cell walls from Arabidospis cell suspension cultures and revealed that a large proportion of the proteins were enzymes, notably carbohydrate active enzymes, peroxidases and proteases.
The Cytosolic Protein Response as a Subcomponent of the Wider Heat Shock Response in Arabidopsis[W]

The CPR in Arabidopsis thaliana is associated with the heat shock promoter element and the involvement of specific heat shock factors (HSFs), notably HSFA2, which appears to be regulated by alternative splicing and non-sense-mediated decay.
