The MADS domain--containing transcription factor FLOWERING LOCUS C (FLC) acts as an inhibitor of flowering and is a convergence point for several pathways that regulate flowering time in Arabidopsis. In naturally occurring late-flowering ecotypes, the FRIGIDA (FRI) gene acts to increase FLC levels, whereas the autonomous floral promotion pathway and vernalization act to reduce FLC expression. P...

Many species belonging to the Scrophularia genus have been used since ancient times as folk remedies for many medical conditions such as scrofulas, scabies, tumors, eczema, psoriasis, inflammations. The aim of this study was to characterize the matrix metalloproteinases (MMPs) inhibitor compounds of the Scrophularia striata extract by bio-guide fractionation. The aerial parts of S. striata were...

A recent study to determine the cause of collar and root rot disease outbreaks of cold tolerant Eucalyptus species in South Africa resulted in the isolation of two putative new Phytophthora species. Based on phylogenetic comparisons using the ITS and beta-tubulin gene regions, these species were shown to be distinct from known species. These differences were also supported by robust morphologic...
Scrophularia amadiyana (Scrophulariaceae), a new species from Iraq and a key to Scrophularia in Iraq
Background: todays, there are considerable efforts to finding plant substances as new drugs in cancer therapy. Scrophularia striata plants are a well-known in traditional medicine in Iran. This prompted us to investigate the anti-tumor effects of Scrophularia striata (an Iranian species) extract on human colorectal cancer (HT29) and normal (HEK293) cell lines. Methods: In this experimental st...

We reared Oedaleus asiaticus grasshoppers under four different single-plant diets to examine the relationships among diet, performance, stress, and transcription patterns. Grasshoppers fed only Artemisia frigida (Asteraceae) were stressed, as indicated by their lower growth, size, development, and survival, in comparison to grasshoppers fed on any of three grasses, Cleistogenes squarrosa, Leymu...
In temperate climates, the prolonged cold temperature of winter serves as a seasonal landmark for winter-annual and biennial plants. In these plants, flowering is blocked before winter. In Arabidopsis thaliana, natural variation in the FRIGIDA (FRI) gene is a major determinate of the rapid-cycling vs. winter-annual flowering habits. In winter-annual accessions of Arabidopsis, FRI activity block...
