Our first tendency is to look outside Europe when searching for ancient rhetorics that do not follow the Greco-Roman tradition. After all, much of European culture was strongly influenced by Roman culture, especially following the conquests of Julius Caesar in 58-51 BCE and subsequent conquests that brought most of Europe under Roman control. Rome’s civic practices, including variations of Grec...

Dendrobium sonia-28 is an important ornamental orchid in the Malaysian flower industry. However, the genus faces both low germination rates and the risk of producing heterozygous progenies. Cryopreservation is currently the favoured long-term storage method for orchids with propagation problems. Vitrification, a frequently used cryopreservation technique, involves the application of pretreatmen...

BACKGROUND The aim of the study was to observe the effect of polysaccharide of dendrobium candidum (PDC) and high glucose on proliferation, apoptosis of human corneal epithelial cells (HCEC). METHODS The MTT method was used to screen and take the optimal high-glucose concentration, treatment time, and PDC concentration using HCEC and divide it into 4 groups: control group (C), high glucose gr...

Auxin response factor (ARF) proteins play roles in plant responses to diverse environmental stresses by binding specifically to the auxin response element in the promoters of target genes. Using our latest public Dendrobium transcriptomes, a comprehensive characterization and analysis of 14 DnARF genes were performed. Three selected DnARFs, including DnARF1, DnARF4, and DnARF6, were confirmed t...

Establishing an aseptic in vitro culture for Dendrobium, or for any plant in fact, is the most important step towards developing an effective in vitro tissue culture including micropropagation protocol. Success in initial aseptic culture will contribute to the successful production of in vitro cultures that may involve the initiation or formation of callus and/or protocorm-like bodies (PLBs), t...

Studying the drivers of host specificity can contribute to our understanding of the origin and evolution of obligate pollination mutualisms. The preference-performance hypothesis predicts that host plant choice of female insects is related mainly to the performance of their offspring. Soil moisture is thought to be particularly important for the survival of larvae and pupae that inhabit soil. I...

chamaemelum nobile (asteraceae) commonly known as 'roman chamomile' is a medicinal plant used for numerous diseases in traditional medicine, although its anticancer activity is unknown. the present study was carried out to investigate the anticancer as well as apoptotic activity of ethyl acetate fraction of c. nobile on different cancerous cell lines. the cells were treated with varyi...
