Sequencing and analysis of a genomic fragment provide an insight into the Dunaliella viridis genomic sequence.

Dunaliella is a genus of wall-less unicellular eukaryotic green alga. Its exceptional resistances to salt and various other stresses have made it an ideal model for stress tolerance study. However, very little is known about its genome and genomic sequences.

OsFY, a homolog of AtFY, encodes a protein that can interact with OsFCA-gamma in rice (Oryza sativa L.).

FCA and FY are flowering time related genes involved in the autonomous flowering pathway in Arabidopsis. FCA interacts with FY to regulate the alternative processing of FCA pre-mRNA. The FCA/FY interaction is also required for the regulation of FLC expression, a major floral repressor in Arabidopsis.

[Transient expression of foreign ble gene in Dunaliella salina].

Plasmid pSP124S with ble gene was transformed into D. salina cell by electroporation. The retention and expression of foreign gene in D.

Influence of Substrate and Ribozyme Sequences on the Functions of Ribozyme.

The mono-component ribozyme RZ1, RZ3 and RZ4 were ligated in different orders into two tri-component ribozymes RZ134 and RZ413.Both tri-component ribozymes could cleave individual specific substrate sequences from different regions of the tobacco mosaic virus (TMV) RNA. The cleavage efficiency and specificity of each unit-ribozymes in the tri-component ribozymes to its substrate was similar to its mono-ribozyme counterpart.
