BACKGROUND Eukaryotic translation initiation factor 4E (eIF4E) plays an important role in plant virus infection as well as the regulation of gene translation. METHODOLOGY/PRINCIPAL FINDINGS Here, we describe the isolation of a cDNA encoding CmeIF(iso)4E (GenBank accession no. JQ904592), an isoform of eIF4E from chrysanthemum, using RACE PCR. We used the CmeIF(iso)4E cDNA for expression profil...

Chrysanthemum is a typical short-day (SD) plant that responds to shortening daylength during the transition from the vegetative to the reproductive phase. FLOWERING LOCUS T (FT)/Heading date 3a (Hd3a) plays a pivotal role in the induction of phase transition and is proposed to encode a florigen. Three FT-like genes were isolated from Chrysanthemum seticuspe (Maxim.) Hand.-Mazz. f. boreale (Maki...

BACKGROUND With the objective of combining multiple resistant traits from wild relative species in florist's chrysanthemums, trigeneric hybridization was conducted by crossing two intergeneric F(1) hybrids Chrysanthemum grandiflorum × Artemisia vulgaris and Chrysanthemum crassum × Crossostephium chinense. METHODOLOGY/PRINCIPAL FINDINGS To assess post-pollination phenomena, we investigated pol...

Viroids are the smallest infectious agents, and their genomes consist of a short single strand of RNA that does not encode any protein. Chrysanthemum stunt viroid (CSVd), a member of the family Pospiviroidae, causes chrysanthemum stunt disease. Here, we report the genomic variations of CSVd to understand the sequence variability of CSVd in different chrysanthemum cultivars. We randomly sampled ...

In recent, Kar.S et.al [ Phys Rev D 67,044005 (2003) ] have obtained static spherically symmetric solutions of the Einstein-Kalb-Ramond field equations. We have shown that their solutions, indeed, represent Wormholes. In Einstein-Cartan theory, the symmetric Christoffel connection is modified with the introduction of an anti-symmetric tensorial term,known as space time torsion, which is presume...

We evaluate flux vacua attractor equations in type IIA string theory compactified on generalized geometries with orientifold projections. The four-dimensional N = 1 superpotential in this compactification is described as a sum of the Ramond-Ramond superpotential and the one described by the (non)geometric flux charges. We demonstrate a single modulus model in which supersymmetric AdS and Minkow...

We find the orbifold analog of the topological relation recently found by Freed and Witten which restricts the allowed D-brane configurations of Type II vacua with a topologically non-trivial flat B-field. The result relies in Douglas proposal – which we derive from worldsheet consistency conditions – of embedding projective representations on open string Chan-Paton factors when considering orb...

Airborne dermatitis belongs to a heterogeneous group of dermatoses of various etiopathology and clinical characteristics. This disease is characterized by acute or chronic inflammation of the uncovered skin exposed to irritants or allergens. Initially skin lesions are transient. The paper presents a description of chrysanthemum growers diagnosed with air-borne dermatitis from chrysanthemum. Eti...

BACKGROUND Chrysanthemum morifolium is an important floral crop that is cultivated worldwide. However, due to a lack of genomic resources, very little information is available concerning the molecular mechanisms of flower development in chrysanthemum. RESULTS The transcriptomes of chrysanthemum vegetative buds, floral buds and buds were sequenced using Illumina paired-end sequencing technolog...

BACKGROUND Simple sequence repeats (SSRs) are ubiquitous in eukaryotic genomes. Chrysanthemum is one of the largest genera in the Asteraceae family. Only few Chrysanthemum expressed sequence tag (EST) sequences have been acquired to date, so the number of available EST-SSR markers is very low. METHODOLOGY/PRINCIPAL FINDINGS Illumina paired-end sequencing technology produced over 53 million se...
