BACKGROUND: Transcriptome map is a powerful tool for a variety of biological studies; transcriptome maps that include different organs, tissues, cells and stages of development are currently available for at least 30 plants. Some of them include samples treated by environmental or biotic stresses. However, most studies explore only limited set of organs and developmental stages (leaves or seedlings). In order to provide broader view of organ-specific strategies of cold stress response we studied expression changes that follow exposure to cold (+ 4 °C) in different aerial parts of plant: cotyledons, hypocotyl, leaves, young flowers, mature flowers and seeds using RNA-seq...

Matricaria is a widespread genus of flowering plants of the family Asteraceae that grow in temperate regions of Europe, Asia, America and Africa. Some of the species are also naturalized in Australia. Some species of this genus such as Chamomiles are recognized medicinal plants and cultivated in several countries for commercial purposes: to obtain its blue essence, as herbal tea, and for pharmaceutical or cosmeceutical uses. The phytochemical composition of Matricaria spp. includes volatile terpenoids (e.g...

Plants are unable to relocate themselves to a more favorable location and thus have to deal with developmental programs and environmental cues wherever they happen to be. It is yet largely unknown how plant cells coordinate cellular activities and architectures to accomplish developmental processes and respond to environmental changes. By identifying and establishing a new cellular model system, we have discovered that two neighboring cell types in the abscission zone (AZ) of Arabidopsis flowers coordinate their activities to ensure a precise "cut" through a highly restricted area of plant tissue to bring about organ separation...

Herbarium specimens deposited in publicly accessible collections are the basis for all scientific names because only permanent specimens can be re-studied by independent researchers, the very essence of science. Re-investigations may be done with morphological, chemical, genomic, computer-tomographic, or other methods. Based on new herbarium material, I here provide a name for the Xishuangbanna gourd, a plant long cultivated in Yunnan because of its large non-bitter fruits, rich in β-carotene. Genome re-sequencing of numerous accessions has shown that this cucumber mutant is closer to Cucumis sativus var...

Unraveling the function of genes affecting agronomic traits is accelerating due to progress in DNA sequencing and other high-throughput genomic approaches. Characterized genes can be exploited by plant breeders by using either marker-aided selection (MAS) or transgenic procedures. Here, we propose a third 'outlet', 'molecular strengthening' (MOST), as alternative option for exploiting detailed molecular understanding of trait expression, which is comparable to the pharmaceutical treatment of human diseases...

The sweet smell of aroma of Jasminum sambac (L.) Ait. is releasing while the flowers are blooming. Although components of volatile oil have been extensively studied, there are problematic issues, such as low efficiency of yield, flavour distortion. Here, the subcritical fluid extraction (SFE) was performed to extract fragrant volatiles from activated carbon that had absorbed the aroma of jasmine flowers. This novel method could effectively obtain main aromatic compounds with quality significantly better than solvent extraction (SE)...

Seed is an essential propagation organ and a critical strategy adopted by terrestrial flowering plants to colonize the land. The ability of seeds to accurately respond to light is vital for plant survival. However, the underlying mechanism is largely unknown. In this study, we reveal a circuit of triple feed-forward loops adopted by Arabidopsis seeds to exclusively repress germination in dark conditions and precisely initiate germination under diverse light conditions. We identify that de-etiolated 1 (DET1), an evolutionarily conserved protein, is a central repressor of light-induced seed germination...

The female flower of hop (Humulus lupulus var. lupulus) is an essential ingredient that gives characteristic aroma, bitterness and durability/stability to beer. However, the molecular genetic basis for identifying DNA markers in hop for breeding and to study its domestication has been poorly established. Here, we provide draft genomes for two hop cultivars [cv. Saazer (SZ) and cv. Shinshu Wase (SW)] and a Japanese wild hop [H. lupulus var. cordifolius; also known as Karahanasou (KR)]. Sequencing and de novo assembly of genomic DNA from heterozygous SW plants generated scaffolds with a total size of 2...

OBJECTIVE: there is evidence of high use of complementary and alternative medicine (CAM) by pregnant women. Despite debate and controversy regarding CAM use in pregnancy there has been little research focus upon the impacts of CAM use on birth outcomes. This paper reports findings outlining the incidence of adverse birth outcomes among women accessing CAM during pregnancy. DESIGN: a survey-based cohort sub-study from the nationally-representative Australian Longitudinal Study on Women's Health (ALSWH) was undertaken in 2010...

The "jin yin hua" (Lonicera japonica Thunb.) used in the clinic nowadays is the flower of honeysuckle, excluding its stem, leave, branch, vine or the whole plant. In the early time, the name of "ren dong" (honeysuckle) or "ren dong teng" (Caulis lonicerae) didn't refer exclusively to the flower of honeysuckle. A few early literature, such as Xin xiu ben cao (Newly Revised Materia Medica) recorded briefly the flower, yet only mentions its time of blossom and shape without mentioning the medicinal use of its flower, nor the title of "jin yin hua", as the identification for this plant...

Flowers, berries, leaves, barks and roots of different plants have been used through the ages as a source of flavor in food and perfume preparations. The volatiles responsible for the flavor of botanicals can be extracted from the plant material as "essential oils" (EOs), called also volatile oils or ethereal oils. The term essential is intended to indicate that the oil is the fragrant essence of the plant from which it is extracted. EOs are constituted by hydrocarbons (monoterpenes and sesquiterpenes) and oxygenated compounds (alcohols, esters, ethers, aldehydes, ketones, lactones, phenols and phenol ethers)...

In 1930, Dr Edward Bach developed flower essences known as Bach flowers. Today, over 70 years later, they are becoming more and more popular and are used by many practitioners, despite a total lack of scientific support for their use. A review of the literature on the controversial use of this alternative treatment is discussed.

Over the past several decades, alternative medicines have gained in popularity for use in both humans and animals. While they are not without controversy, client interest and usage dictate that even those practitioners who do not want to practice any of them in their own hospital or clinic should at least be aware of their common use, safety, and efficacy. The author briefly discusses some of the more popular alternative medicines—acupuncture, chiropractic, herbal, homeopathic, and flower essences—with respect to some of the basics that every practitioner should know about them...

A placebo by proxy effect occurs when a patient's response to therapy, assessed either objectively or subjectively, is affected by the behavior of other people who know that the patient is undergoing therapy. We recruited 58 children aged 2-5 years who reported frequent tantrums and examined the effect of a pharmacologically inert substance (flower essence) that is purported by the manufacturers to reduce temper tantrums. Tantrum frequency, tantrum severity, and parental mood were measured on 5 occasions over 8 days before treatment and on a further 5 occasions over 10 days after the start of treatment...
