Abstract
In plants plasmodesmata PD are intercellular channels that function in both metabolite exchange and the transport of proteins and RNAs Currently many of the PD structural and regulatory components remain to be elucidated Receptorlike kinases RLKs belonging to a notably expanded protein family in plants compared to the animal kingdom have been shown to play important roles in plant growth development pathogen resistance and cell death In this study cell biological approaches were used to identify potential PDassociated RLK proteins among proteins contained within cell walls isolated from rice callus cultured cells A total of 15 rice RLKs were investigated to determine their subcellular localization using an Agrobacteriummediated transient expression system Of these six PDassociated RLKs were identified based on their colocalization with a viral movement protein that served as a PD marker plasmolysis experiments and subcellular localization at points of wall contact between spongy mesophyll cells These findings suggest potential PD functions in apoplasmic signaling in response to environmental stimuli and developmental inputs
