It provides a direct ce _to_ ce cytop asmic pathway for materia transport and message transference, and converts the co onies of independent ce s into an interconnected symp ast system. Many evidences indicated that the p as modesmata coordinate gene expression and ce u ar physio ogica and biochemica processes . So that they p ay importment ro es in p ant growth and deve opment, as we as in the response and adapta tion of p ants to environmenta changes. This paper summarizes the recent progress in studies on the p asmodesmata diversity, the regu ation of p asmodesma SEL , the p asmodesma macromo ecu e trafficking and the symp asmic domains in re ation to p ant morphogenesis and dormancy, etc. Key words P asmodesma, P asmodesma diversity, Symp ast, Symp asmic domain , Interce u ar macromo ecu e trafficking, Regu ation of p asmodesma channe s ( suprace u ar structure, Lucas et al, 1993) , !( symp ast ) , , , , ( Mezitt and Lucas , 1996; Ghoshroy et al, 1997; Ding, 1998) , ( Lucas et al, 1993; Ding et al , 1999) , , : : : 4 40 20 ; , , ( symp asmic do main) , , , , , ( Robards and Lucas, 1990; Lucas et al, 1993; Mezitt and Lucas, 1996; Ding et a
