Cloning, transformation and expression of cell cycle-associated protein kinase in indica rice ().

The development process of seed in plants is a cycle of cells which occur gradually and regularly. One of the genes involved in controling this stage is the gene. encode protein kinase which plays an important role in phosphorylation, inactivation of cyclin-dependent kinase 1 (CDK1)-cyclin (CYC) and inhibiting cell division at mitotic phase.

Potential role of the rice OsCCS52A gene in endoreduplication.

In eukaryotes, the cell cycle consists of four distinct phases: G1, S, G2 and M. In certain condition, the cells skip M-phase and undergo endoreduplication. Endoreduplication, occurring during a modified cell cycle, duplicates the entire genome without being followed by M-phase.

Functional characterization of orchardgrass endoplasmic reticulum-resident Hsp90 (DgHsp90) as a chaperone and an ATPase.

Hsp90 proteins are essential molecular chaperones regulating multiple cellular processes in distinct subcellular organelles. In this study, we report the functional characterization of a cDNA encoding endoplasmic reticulum (ER)-resident Hsp90 from orchardgrass (DgHsp90). DgHsp90 is a 2742bp cDNA with an open reading frame predicted to encode an 808 amino acid protein.

Characterization of orchardgrass p23, a flowering plant Hsp90 cohort protein.

p23 is a heat shock protein 90 (Hsp90) co-chaperone and stabilizes the Hsp90 heterocomplex in mammals and yeast. In this study, we isolated a complementary DNA (cDNA) encoding p23 from orchardgrass (Dgp23) and characterized its functional roles under conditions of thermal stress. Dgp23 is a 911 bp cDNA with an open reading frame predicted to encode a 180 amino acid protein.

Identification and characterization of a gene encoding drought-inducible protein localizing in the bundle sheath cell of sugarcane.

We have identified a drought-inducible gene, designated as SoDip22, in sugarcane leaves. The cDNA encoded a hydrophilic protein with a calculated molecular mass of 15.9 kDa and the amino acid sequence was similar to that of ABA, stress and ripening-inducible protein from various plant species.
