A Mutant Isolated from the Cyanobacterium Synechococcus PCC7942 Is Unable to Adapt to Low Inorganic Carbon Conditions.

abstract：:Plasmodesmata act as key elements in intercellular communication, coordinating processes related to plant growth, development, and responses to environmental stresses. While many of the developmental, biotic, and abiotic signals are primarily perceived at the plasma membrane (PM) by receptor proteins, plasmodesmata al...
