| the role of plant cctalpha in salt- and osmotic-stress tolerance. | to find key genes essential for salt tolerance in the mangrove plant, bruguiera sexangula, functional screening was performed using escherichia coli as the host organism. a transformant expressing a cytosolic chaperonin-containing tcp-1alpha (cctalpha) homologue displayed enhanced salt tolerance. analysis in e. coli of the functional region revealed that a sequence of only 218 amino acids, containing the apical domain, is necessary for osmotolerance. furthermore, this domain shows chaperone acti ... | 2002 | 12354922 |
| genomic markers reveal introgressive hybridization in the indo-west pacific mangroves: a case study. | biodiversity of mangrove ecosystems is difficult to assess, at least partly due to lack of genetic verification of morphology-based documentation of species. natural hybridization, on the one hand, plays an important role in evolution as a source of novel gene combinations and a mechanism of speciation. however, on the other hand, recurrent introgression allows gene flow between species and could reverse the process of genetic differentiation among populations required for speciation. to underst ... | 2011 | 21589927 |
