Ageing is an inevitable natural phenomenon characterized by physiological function deterioration and cell homeostasis disorder .Young leaf of mulberry is a common vegetable widely consumed in Asia . It has special delicious taste and has been used to make many dietary foods by adding other food materials .Moreover , as a medicinal and edible plant , mulberry leaves have been used as dietary supplements or ingredient in functional foods due to their health benefits .Previous study has been sug...

Histone replacement during chromatin-remodeling plays a key role in transcriptional regulation .Replacing their canonical counterparts by histone variants often leads to gene expression changes in eukaryotes , which is one of the most important biological responses to stresses caused by temperature , drought , salinity and heavy metals .Insert shows interaction among AtOXS3 , Swc2 and H2A . Z .

Paphiopedilum is an important genus of the orchid family Orchidaceae and has high horticultural value .The wild populations are under threat of extinction because of overcollection and habitat destruction .Mature seeds of most Paphiopedilum species are difficult to germinate , which severely restricts their germplasm conservation and commercial production .Many orchid seeds including Paphiopedilum are tiny and contain no endosperm ( Figure1 ) .Lignin biosynthesis pathway in P . armeniacum.

Liu Xu at the Agricultural and Biotechnology Research Center of South China Botanical Garden , Chinese Academy of Sciences .Revealed a novel mechanism in regulation of endoplasmic reticulum stress-induced cell death in plants .This finding was published online in plant physiology on July.Yang Yuhua and Liu Xu are the co-first authors of this paper , and Hou Xingliang is the corresponding author .The link to t...

Dendrobium officinale , as a time-honored tonic food and precious Chinese herbal medicine , is an epiphytic orchid plant , which grows on the trunks , cliffs or rocks , and usually faces up to diverse environmental stresses ( e . g . cold and heat stress .Plant DNA methylation , a conserved and important epigenetic modification , depends on the dynamics of antagonistic DNA methylation and DNA demethylation , but their roles in D . officinale are still unknown .

Orchid plants are the most species-rich plants and highly interact with pollinators via visual or olfactory cues .In the absence of JA or low JA , DobHLH4 interacts with DoJAZ1 without targeting DoTPS10 , which attenuates the transcriptional activation activity of DobHLH4 at the DoTPS10 promoter , thereby decreasing linalool accumulation .The present study illustrates that DobHLH4 acts as a positive regulator in linalool biosynthesis , and provide a feasible strategy for promoting linalool ac...

Plants have evolved a set of highly sophisticated mechanisms to deal with environmental stresses and to survive in a cost-efficient manner. For example, upon pathogen attack, plants reallocate their limited resources away from growth towards defense against pathogens, and this trade-off between growth and defense is finely balanced to optimize fitness. To date, extensive researches on how plants recognize and response to pathogens have been done, but the molecular mechanisms underlying fine-t...

By 2050, the world’s population is predicted to reach 9.8 billion and food production through conventional agriculture has been straining the global environment. Moreover, urbanization has continued to reduce farmland capacity and farm labor. The rise in urbanization also means that more food needs to be transported into inner cities, and the increasing food miles demand greater efficiency in food preservation.

While GM crops of past years contain one to few traits, the continuous discovery of new trait genes would mean that over time, crops could end up with a large number of transgene insertions. If they were dispersed throughout the genome, extensive breeding would be needed to reassemble all of them into a single breeding line. Stacking new DNA to a preexisting transgenic locus insures that the package of transgenes can be transmitted through breeding programs as a single locus rather than segre...

Exposure to cadmium (Cd), a toxic heavy metal classified as a group 1 carcinogen can lead to cancer, osteoporosis and renal disorder. Contamination of soil with Cd results in human dietary intake from plant-derived food, with rice as the major source of dietary Cd for nearly half of the world’s population that relies on it as a staple.
