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.

Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant economic losses for the swine industry worldwide. The PRRSV E protein, encoded by ORF 2b, is one of the non-glycosylated minor structural proteins. In this study, we present evidence for the interaction of the E protein with mitochondrial proteins ATP5A (part of ATP synthase complex), prohibitin, and ADP/ATP translocase. We additionally demonstrate partial mitochondrial localization of the E protein in transfected cells. To functionally investigate these interactions, we infected MARC-145 cells with PRRSV or alphavirus replicon particles (VRPs) expressing PRRSV E protein. In infected cells, production of ATP was significantly reduced. The E protein also induced apoptosis by activating caspase-3, which results in PARP cleavage. Taken together, these data suggest that the PRRSV E protein interacts with mitochondrial proteins and induces apoptosis by inhibiting ATP production.
