A numb mechanisms are involved in telling a cell where it is. Technical Abstract: Recent genome sequencing efforts illustrate the fact that plants and animal e many sequences in common, suggesting that they have either co- opted the molecules for different purposes, or that they utilize similar mechanisms ( au and Pont-Lezica, 1995; Clark, 1996). One might expect many housekeeping s, such as regulation of the cell cycle, to be similar in plants and animal lt what of the multicellular tasks, the develomental processes that coordin owth and differentiation of cells? To begin with, plant cells never move, induction by cell movement such as occurs during gastrulation in animal emb evelopment, is not likely to occur. Lineage-based development would be con nt in plants since they are forever attached to their parent cell, however, few exceptions (Sachs, 1978), plant cells do not appear to differentiate b on lineage. How, then do plant cells find their cues? |
