The aim of this work was to improve understanding of the regulation of alkaloid biosynthesis in two Solanaceae plants, Nicotiana tabacum (tobacco) and Hyoscyamus muticus (Egyptian henbane). In order to map the biosynthetic genes involved in the tobacco alkaloid pathway, a functional genomics-based technology was established by combining genome-based transcript profiling (cDNA-AFLP) with targete...

to investigate the effects of methyl jasmonate growth regulators on growth characteristics, fruit number and fruit yield of ‘semsuri’ melon, an experiment at the field of shahid bahonar university was conducted in summer 2012. melon (cv. ‘semsuri’) is widely cultivated in iran and therefore increasing the fruit yield and quality of this cultivar is necessary. some growth regulators including me...

The most economically important centellosides, madecassoside and asiaticoside, are produced in very low amounts Centella asiatica (L.) Urban roots. With the aim of overcoming this limitation, work we compared effect different elicitors on centelloside production hairy root cultures established by Agrobacterium rhizogenes infection. Additionally, elicitor-induced changes expression key biosynthe...

Ultraviolet B (UV-B) radiation, a very small fraction of the daylight spectrum, elicits changes in plant secondary metabolism that have large effects on plant-insect interactions. The signal transduction pathways that mediate these specific effects of solar UV-B are not known. We examined the role of jasmonate signaling by measuring responses to UV-B in wild-type and transgenic jasmonate-defici...

The main object of this study is to investigate the effect of plant growth regulators on the prolongation of vase life of two kinds of cut carnation under normal and ethylene. Carnation is one of the most popular flowers that has a short life due to its sensitivity to ethylene. Also, the effect of plant growth regulators on several physiological traits under ethylene stress and normal condition...

The plant hormones jasmonic acid and methyl jasmonate, along with their intermediate compounds, produced in the octadecanoid pathway, are important signaling molecules that are collectively called jasmonates. These are widespread in the plant kingdom and play crucial roles in biotic/abiotic stress responses, as well as in processes related to plant growth and development. Recently, it has been ...
