Cloning and characterization of a novel Hsp100/Clp gene (osClpD) from Oryza sativa.

A novel osClpD gene, encoding a highly conservative ClpD subfamily member, was first isolated and characterized from Oryza sativa. The full-length cDNA of osClpD gene was 3140 bp and contained a 2884 bp open reading frame encoding a 938 amino acid protein. The phylogenetic tree and blast search showed that OSClpD belonged to the ClpD subfamily of the Hsp100/Clp family, and contained all protein motifs characteristic for the ClpD subfamily of Hsp100/Clp proteins.

Isolation and expression of cold-regulated cDNA from Chinese cabbage (Brassica pekinensis).

It has been established that changes in gene expression occur during cold acclimation in a wide range of plants. Here we present a novel cDNA encoding a protein with a calculated molecular mass of 25 kDa, designated cor25, from Brassica pekinensis cv. Zaoshu 5 (Chinese cabbage) that was similar with a cold-regulated Arabidopsis thaliana L.

Molecular cloning and characterization of a novel lectin gene from Zephyranthes candida.

A new lectin gene was cloned from Zephyranthes candida by using RACE-PCR. The full-length cDNA of Zephyranthes candida agglutinin (ZCA) was 647 bp and contained a 477 bp open reading frame encoding a 159 amino acid protein. Zephyranthes candida lectin gene was found to encode a precursor lectin with signal peptide and had extensive homology with those of other plant lectins.
