Rising temperatures and ocean acidification driven by anthropogenic carbon emissions threaten both tropical and temperate corals. However, the synergistic effect of these stressors on coral physiology is still poorly understood, in particular for cold-water corals. This study assessed changes in key physiological parameters (calcification, respiration and ammonium excretion) of the widespread c...

Expression of the PSR132 protein from Dianthus caryophyllus (carnation, clover pink) is induced in response to ethylene production associated with petal senescence, and thus the protein is named petal death protein (PDP). Recent work has established that despite the annotation of PDP in sequence databases as carboxyphosphoenolpyruvate mutase, the enzyme is actually a C-C bond cleaving lyase exh...

The effects of ethylene and ultraviolet (UV) irradiation on parameters of senescence in carnation (Dianthus caryophyllus L. cv White Sim) flowers were characterized and compared.UV irradiation (lambda(max) = 254 nanometers), at fluences above 18 kilojoules per square meter, induced petal in-rolling, similar to that which occurred during natural senescence or after ethylene treatment. Increase i...

The present research work involves shoot formation, their multiplication and rooting in carnation Dianthus caryophyllous. For shoot formation both apical and nodal meristems were used. MS medium containing BAP alone or in combination with kinetin was tested. Best shoot formation response was obtained after 6 days of inoculation from apical meristem and after 7 days of inoculation from nodal mer...

Ecological processes in the deep sea are poorly understood due to the logistical constraints of sampling thousands of metres below the ocean's surface and remote from most land masses. Under such circumstances, genetic data provides unparalleled insight into biological and ecological relationships. We use microsatellite DNA to compare the population structure, reproductive mode and dispersal ca...

Urbanization leads to higher phosphorus (P) concentration in urban catchments. Among different stormwater retention measures, green roofs are the least efficient in phosphorus retention. Moreover, much research has shown that green roofs act as sources of phosphorus, and they can emit P in significant loads. In this study low P emission green roof substrate was developed based on the proposed s...

Specimens were studied of 65 samples of the genus Aphidura (Aphididae, Aphidinae, Macrosiphini) from the collection of the Muséum national d'Histoire naturelle (Paris). The possible synonymies of three pairs of species are discussed. New aphid host plant relationships are reported for Aphidura bozhkoae, Aphidura delmasi, Aphidura ornata, Aphidura pannonica and Aphidura picta; this last species ...

ABSTRACT Edible flowers are rich in bioactive compounds and pigments that on increasing demand nutraceutical, medicinal, food, cosmetic dyeing industries. This study evaluated the anthocyanins, phenolics antioxidant activity of eight edible ( Bellis perennis L., Centaurea cyanus Dianthus carthusianorum Lavandula angustifolia Mill., Primula vulgaris Huds., Rosa canina pendulina L. Viola odorata ...
