The Oenothera mitochondrial genome contains only a gene fragment for ribosomal protein S12 (rps12), while other plants encode a functional gene in the mitochondrion. The complete Oenothera rps12 gene is located in the nucleus. The transit sequence necessary to target this protein to the mitochondrion is encoded by a 5'-extension of the open reading frame. Comparison of the amino acid sequence e...

The formation of hemozoin (malaria pigment) has been proposed as an ideal drug target for antimalarial screening programs. In this study, we used an improved, cost-effective and high-throughput spectrophotometric assay to screen plant extracts for finding novel antimalarial plant sources. Fifteen extracts with different polarity from three Iranian Artemisia species, A. ciniformis, A. biennis an...

The genetic behavior of ~Enothera biennis and O. syrticola (0. muricata L.) as uniform and constant species is now generally explained by the assumption of the presence of two gametic lethal factors. The reciprocal hybrids of these forms are unlike each other and the double reciprocal hybrids return to the grandparental types. I t is assumed that there are two kinds of gametes, but that one of ...

Evening primrose (Oenothera biennis L.) is native to North America, belongs to Onagraceae family, and is a biennial plant. This experiment was performed as factorial based on a completely randomized design in three replications. The main purpose of the study was to evaluate the effect of moist-chilling and GA</s...
