This paper explores elegant design variations for Spirographs to display Tweets. Our method consisted in first tweaking Spirographs parameters using a drawing tool we developed specifically. We then identified particularly interesting Spirographs patterns and gave them flower names to better recall and describe them: sunflower, daisy or chrysanthemum, to name a few. We further customized those ...

Loop-loop tertiary interactions play a key role in the folding and catalytic activity of natural hammerhead ribozymes. Using a combination of NMR spectroscopy, site-directed mutagenesis and kinetic and infectivity analyses, we have examined the structure and function of loops 1 and 2 of the (+) and (-) hammerheads of chrysanthemum chlorotic mottle viroid RNA. In both hammerheads, loop 1 is a he...

Nitrate transporters are an important component of plant growth and development. Chrysanthemum morifolium is an important ornamental species, for which a sufficient supply of nitrogenous fertilizer is required to maintain economic yields. In this study, the full-length cDNA of the nitrate transporter genes CmNRT2 and CmNAR2 were isolated. CmNRT2 transcript accumulation was inducible by both nit...

Chrysanthemum sp. is a floricultural plant of the Asteraceae family with high economic value. The anthocyanin pigment in red chrysanthemum acts as an antioxidant, content which can be influenced by genetic factors such physiological age flower. This study aimed to determine effect flower on and antioxidant activity plants. used was 115 Days After Planting (DAP) (early bloom stage), 120 DAP (hal...

Flowering time and an ability to tolerate abiotic stresses are important for plant growth and development. We characterized BBX24, a zinc finger transcription factor gene, from Chrysanthemum morifolium and found it to be associated with both flowering time and stress tolerance. Transgenic lines with suppressed expression of Cm-BBX24 (Cm-BBX24-RNAi) flowered earlier than wild-type plants and sho...

The mutation rates of viroids, plant pathogens with minimal non-protein-coding RNA genomes, are unknown. Their replication is mediated by host RNA polymerases and, in some cases, by hammerhead ribozymes, small self-cleaving motifs embedded in the viroid. By using the principle that the population frequency of nonviable genotypes equals the mutation rate, we screened for changes that inactivated...

BLACK The importance of herbal hypolipidemics has increased to fill the lacunae created by allopathic medicines. Coriander is a spice, which is used in daily cooking especially in India. In Ayurvedic literature it is reported to possess hypolipidemic activity. Hence, to validate these ancient known property researchers at International Institute of Biotechnology and Toxicology, Padappai, Tamil ...

We present a new muon propagation Monte Carlo FORTRAN code MUM (MUons+Medium) which possesses some advantages over analogous codes presently in use. The most important features of the algorithm are described. Data on the test for algorithm accuracy are presented. Contributions of different sources to the resulting error of simulation are considered. Selected results obtained with MUM are given ...

Pyrethrins are a class of natural terpenoid pesticides produced by Tanacetum cinerariifolium, commonly known as chrysanthemum. Here we present evidence that cannabis may be able to produce pyrethrins endogenously. Flower from a cannabis plant grown in a closed hydroponic environment contained 2.48 parts per million pyrethrin I by weight. A comparison of the genetics of T. cinerariifolium and Ca...
