In the past few decades there has been an exponential growth in the field of herbal medicine to be a better option for their healthcare needs, owing to their natural origin and reduced side effects. Datura spp. is one of the 50 fundamental herbs used in traditional medicine. The dry flower, particularly the violet coloured, if rolled and used like cigar, will help to relive the asthma or wheezi...

background & aim: milk thistle [silybum marianum (l.) gaertn] is an annual or biennial plant, native to the mediterranean area, which has spread in north and south of iran. a fruit of milk thistle contains a relatively high amount (approx. 20%) of oil, which exhibits wound-healing, anti-burn, and hepatoprotective properties. experimental: in this research, a pot experiment was conducted usi...

This study evaluated whether the herb Ruellia nudiflora is locally adapted to a specialist insect seed predator (SP) and insect folivores, and if plant local adaptation (LA) to the former is more likely. A reciprocal transplant experiment was conducted using three sites in Yucatan (Mexico) (n = 864 plants). A third of the plants of each origin were placed at each site, and we recorded the follo...

We construct a large class of explicit, asymptotically flat and regular wormhole solutions in higher order scalar tensor theories. The are vacuum theory no matter (exotic or regular) is introduced to support them. They constructed via general disformal transformation seed black hole solution. belong particular Horndeski which requires the presence all extended Galileons has dimensional Lovelock...

Context. The interplay of thermal and bulk motion Comptonization to explain the spectral evolution of neutron star LMXBs including transient hard X-ray tails is gaining a strong theoretical and observational support. The last momentum has been given by the advent of a new XSPEC Comptonization model, COMPTB, which includes thermal and bulk Comptonization. Aims. We used COMPTB to investigate the ...

MicroRNAs (miRNAs) are short, single stranded RNA molecules that regulate the stability and translation of messenger RNAs in diverse eukaryotic groups. Several miRNA genes are of ancient origin and have been maintained in the genomes of animal and plant taxa for hundreds of millions of years, playing key roles in development and physiology. In the last decade, genome and small RNA (sRNA) sequen...

Understanding local adaptation of tree populations to climate allows the development of assisted migration guidelines as a tool for forest managers to address climate change. Here, we study the relationship among climate, a wide range of physiological traits, and field performance of selected white spruce provenances originating from throughout the species range. Tree height, survival, cold har...

Winter warming and its accompanying predicted decrease in snow pack for northern temperate regions may increase frost damage to plants induced by an increase in freeze-thaw cycles (FTCs) due to reduced insulation. FTC frequency, minimum temperature during freezing and pre-existing local adaptations potentially all influence site-specific plant responses to future climatic changes. Within a cham...

Plants have a long evolutionary history, during which mass extinction events dramatically affected Earth's ecosystems and its biodiversity. The fossil record can shed light on the diversification dynamics of plant life and reveal how changes in the origination-extinction balance have contributed to shaping the current flora. We use a novel Bayesian approach to estimate origination and extinctio...

Pentatricopeptide repeat (PPR) proteins are extensive in all eukaryotes. Their functions remain as yet largely unknown. Mining potential stress responsive PPRs, and checking whether known PPR editing factors are affected in the stress treatments. It is beneficial to elucidate the regulation mechanism of PPRs involved in biotic and abiotic stress. Here, we explored the characteristics and origin...
