Asymmetric cell division (ACD) is universally required for the development of multicellular organisms. Unlike animal cells, plant cells have a rigid cellulosic extracellular matrix, the cell wall, which provides physical support and forms communication routes. This fundamental difference leads to some unique mechanisms in plants for generating asymmetries during cell division. However, plants also...
Cell polarization is linked to fate determination during asymmetric division of plant stem cells, but the underlying molecular mechanisms remain unknown. In Arabidopsis, BREAKING OF ASYMMETRY IN THE STOMATAL LINEAGE (BASL) is polarized to control stomatal asymmetric division. A mitogen-activated protein kinase (MAPK) cascade determines terminal stomatal fate by promoting the degradation of the lineage...
Variations among 19 wetland plant species in the tolerance and uptake of Cd, Pb and Zn from wastewater were investigated. The results showed that there were obvious differences among the plant species in metal tolerance. In metal polluted water, plant biomass was significantly reduced for three species, but was significantly increased for three other species. The variation among 19 plant species in...
