Rhizobium rhizogenes-mediated plant hairy root induction is a convenient method for functional study of root-specific genes. To develop an optimized tobacco system and gene function in nicotine biosynthesis, we investigated by three R. rhizogenes strains, R1601, K599, LBA9402, on different media with leaf discs from plants ages, observed that the strain LBA9402 used explant infection exhibited ...

Enhanced Expression of Genes Involved in the Biosynthesis Pathway Tanshinones Tetraploid Plants Salvia Officinalis L.

In this study, silver nanoparticles were synthesized  using the fungus, Aspergillus fumigatus. The effects of three independent variables including glucose content of culture media, initial pH and initial spore concentration on biosynthesis of silver nanoparticles were investigated. These variables affect cell morphology, cell mass, size and morphology of silver nanoparticles and degree of silv...

Recent data showed that phenylpropanoid compound, methylchavicol is essential component of Iranian cultivars of basil. Studying their occurrence during development of plant may help to elucidate the role of phenylpropanoids in plant cell physiology. We followed the phenylpropanoids concentration and the expression of genes related to their biosynthesis during growth and development of two culti...

Podophyllum species, the source of important secondary metabolite, podophyllotoxin, is over-exploited for production anti-cancer drugs endangering this genus globally. Lack complete knowledge on podophyllotoxin biosynthesis a major drawback in its cultivation and identification alternative plants. The current study secoisolariciresinol dehydrogenase, dirigent protein oxidase pluviatolide syntha...

Climate change has been associated with intensified harmful algal blooms (HABs). Some microalgae produce toxins that accumulate in food webs, adversely affecting the environment, public health and economy. Ocean acidification (OA) is a major consequence of high anthropogenic CO2 emissions. The carbon chemistry pH aquatic ecosystems have significantly altered as result. impacts climate on metabo...
