To analyze differences in flower longevity and ethylene sensitivity, we isolated Rosa hybrida gene fragments with sequence similarity to the Arabidopsis thaliana ethylene receptor gene-family. A rose gene (RhETR1) highly similar to AtERS1 had been previously sequenced. Here, we report the isolation

Sugar has only recently been identified as a key player in triggering bud outgrowth, while hormonal control of bud outgrowth is already well established. To get a better understanding of sugar control, the present study investigated how sugar availability modulates the hormonal network during bud

At present, research on the flower color of Rosa rugosa requires very innovative and practical studies. Glycosylation plays an important role in increasing the stability and solubility of anthocyanins in plants. In this study, a gene with a full-length cDNA of 1161 bp encoding 386 amino acids,

BACKGROUND Flower development is central to angiosperm reproduction and is regulated by a broad range of endogenous and exogenous stimuli. It has been well documented that ambient temperature plays a key role in controlling flowering time; however, the mechanisms by which temperature regulates

Plant transcription factors involved in stress responses are generally classified by their involvement in either the abscisic acid (ABA)-dependent or the ABA-independent regulatory pathways. A stress-associated NAC gene from rose (Rosa hybrida), RhNAC3, was previously found to increase dehydration

The late embryogenesis abundant (LEA) protein family is a large protein family that is closely associated with resistance to abiotic stresses in many organisms, such as plants, bacteria and animals. In this study, we isolated a LEA gene, RcLEA, which was cytoplasm-localized, from Rosa chinensis.

A LEAFY-like gene was cloned in the long-day (LD) plant, Silene coeli-rosa (ScLFY). The open reading frame spans 1452 bp encoding a putative protein of 483 amino acids. Amino acid homology to other LFYs is 43-55%; conserved and variable regions were similar to others. However, an intron (808 bp) not

The HAP3 subfamily gene RcLEC1-B, was isolated from protocorm-like body (PLB) of Rosa canina, encodes 213 amino acid residues. It was shown that RcLEC1-B was specifically expressed in PLB of R. canina and its subcellular localization is in the nucleus. Overexpression of RcLEC1-B in Arabidopsis

Cell expansion is crucial for plant growth. It is well known that the phytohormone ethylene functions in plant development as a key modulator of cell expansion. However, the role of ethylene in the regulation of this process remains unclear. In this study, 2,189 ethylene-responsive transcripts were

In our previous study, we identified a Rosa chinensis heat shock protein (HSP) gene, RcHSP17.8, which was induced by abiotic stresses, such as high temperature and osmotic stress. To analyze the expression of RcHSP17.8 and the function of cis-acting elements in the promoter region, a 1,910 bp

We isolated AGAMOUS-like cDNA clones called MASAKO C1-C6 (C4-C6 are 3' or 5' partial cDNA clones) and MASAKO D1 from wild rose (Rosa rugosa Thunb. ex Murray). We found that MASAKO C1 was a homologue of AGAMOUS on the basis of sequence similarity, conservation of intron positions, and stamen- and

trans-Cinnamic acid (CA) is a precursor of many phenylpropanoid compounds, including catechins and aroma compounds, in tea (Camellia sinensis) leaves, and is derived from L-phenylalanine (L-Phe) deamination. We have discovered an alternative CA formation pathway from L-Phe via phenylpyruvic acid

The nucleotide sequences of regulatory elements from homologous genes can be strongly divergent. Phylogenetic footprinting, a comparative analysis of noncoding regions, can detect putative transcription factor binding sites (TFBSs) shared among the regulatory regions of 2 or more homologous genes.

We have quantitatively measured nitric oxide production in the leaves of Arabidopsis thaliana and Vicia faba by adapting ferrous dithiocarbamate spin tapping methods previously used in animal systems. Hydrophobic diethyldithiocarbamate complexes were used to measure NO interacting with membranes,
