Plasmodesmata
What are plasmodesmata? The word plasmodesma derives from the Latin ‘plasmo’ meaning fluid and the Greek ‘desma’ meaning bond. The origin of the word exactly exposes the function of plasmodesmata. Plant cells are encased in cell walls that form the plant skeleton, enabling and stabilizing three-dimensional growth. Just think what would celery be without plant cells walls? However, the presence ...
متن کاملPlasmodesmata form and function.
Intercellular transport via plasmodesmata controls cell fate decisions in plants, and is of fundamental importance in viral movement, disease resistance, and the spread of RNAi signals. Although plasmodesmata appear to be unique to plant cells, they may have structural and functional similarities to the newly discovered tunneling nanotubes that connect animal cells. Recently, proteins that loca...
متن کاملPlasmodesmata “in Communicado”
Cell-to-cell communication is fundamental to multicellular life. For this to occur effectively there must be pathways and dynamic networks for communication. These might depend upon electrical or chemical signals or the mass transfer of molecules between adjacent cells. Molecular communication occurs either via an extra-cellular pathway or through physical structures, called plasmodesmata, that...
متن کاملPlasmodesmata-associated proteins
Encased in rigid cell walls, plant cells have evolved unique channel structures, plasmodesma (Pd), to create a pathway for molecular exchange between adjacent cells. Pd are basically cytoplasmic channels through the cell wall, which are lined by plasma membrane, and contain a modified strand of ER that spans them. These structures provide cytoplasmic and membrane continuity between connected ce...
متن کاملPromoting passage in plasmodesmata
Hox signals death for neuronal precursors he number of neurons in an adult fly is determined by a death-inducing blast of a homeodomain protein, based on results from When the fly larva hatches, neurons are nearly evenly distributed along the major body axis. But in the adult, they are more numerous in the segments of the thorax than the abdomen, in part because neural stem cells (NSCs) in the ...
