The atp6 gene, encoding the ATP6 subunit of F(1)F(0)-ATP synthase, has thus far been found only as an mtDNA-encoded gene. However, atp6 is absent from mtDNAs of some species, including that of Chlamydomonas reinhardtii. Analysis of C. reinhardtii expressed sequence tags revealed three overlapping sequences that encoded a protein with similarity to ATP6 proteins. PCR and 5'- and 3'-RACE were used to obtain the complete cDNA and genomic sequences of C. reinhardtii atp6. The atp6 gene exhibited characteristics of a nucleus-encoded gene: Southern hybridization signals consistent with nuclear localization, the presence of introns, and a codon usage and a polyadenylation signal typical of nuclear genes. The corresponding ATP6 protein was confirmed as a subunit of the mitochondrial F(1)F(0)-ATP synthase from C. reinhardtii by N-terminal sequencing. The predicted ATP6 polypeptide has a 107-amino acid cleavable mitochondrial targeting sequence. The mean hydrophobicity of the protein is decreased in those transmembrane regions that are predicted not to participate directly in proton translocation or in intersubunit contacts with the multimeric ring of c subunits. This is the first example of a mitochondrial protein with more than two transmembrane stretches, directly involved in proton translocation, that is nucleus-encoded.

F-box protein is an important subunit of SCF complex, an E3 ligase in ubiquitin system, and its function is determined through mediating the specific recognition and combining with substrate protein. TaFRA (F-box protein related to abiotic stress) was identified by RACE based on the fragments diferently expressing in wheat seedling exposed to salt stress and encodes an F-box protein. In this study, pBD-TaFRA bait expression vector was constructed, and cDNA+pGAD+pBD was directly co-transformed into yeast hybrid system to screen condidate proteins interacting with TaFRA. Fourty-four candidate proteins were obtained, in which 32 were known proteins and transcript factors related to stress tolerance such as thioredoxin, metallothinein, ATP synthase, and serine/threonine protein kinase etc. This indicates that TaFRA participates in stress response through regulating above condidate genes, which will provide basis for revealing the mechanism of TaFRA reaction to abiotic stress.

The safflower floret is a traditional Chinese medicine used to promote blood circulation and remove obstruction in the channels. The spines on its bracts are considered a handicap when manual harvest is involved. In this study, cDNA-SRAP was used to systematically investigate which genes are associated with the spines. Sixty pairs of possible primer combinations were used on two cDNA pools representing spininess and spinelessness. Six transcript-derived fragments were identified, of which two with low recombination were sequenced successfully and named as GPY-1 and GPY-2. By using the RACE method, the full-length cDNA of GPY-2 is cloned and named as CTL-spn. The full-length cDNA of CTL-spn was 1 679 bp long with a 1 524 bp ORF encoding a 508 aminoacid protein. The deduced amino acid sequence of the CTL-spn gene shared a high homology (97%) with other known ATP synthase CF1 alpha subunits. Semiquantitative RT-PCR analysis revealed that the mRNA of GPY-1 and GPY-2 accumulated in only spiny lines. Considering the important role of ATP synthase CF1 alpha subunit in plants, it may directly take part in the formation process of spininess and enhancing resistance reaction of spiny safflower. Also, our results provide the important insights for breeding spineless cultivars of safflower.
