Small molecules capable of uncoupling growth-defense in plants are currently not known. In this study, for the first time, semi-synthetic analogues of the phytohormone JA-Ile are employed to uncouple growth and defense responses in wild tobacco. The JA-Ile analogues are easily synthesized from inexpensive substrates via olefin metathesis.

We describe a method for the simulation of the growth of elongated plant organs, such as seedling roots. By combining a midline representation of the organ on a tissue scale and a vertex-based representation on the cell scale, we obtain a multiscale method, which is able to both simulate organ growth and incorporate cell-scale processes. Equations for the evolution of the midline are obtained, ...

the aim of this study was to identify the effect of spermine and salicylic acid on several growth parameters, such as shoot length, shoot fresh and dry weights, amount of protein and carbohydrate, of badami and qazvini pistachio cultivated variety under copper stress. the experiment design was completely randomized with three replicates per treatment and four levels of copper (o.5, 30, 45, 60 µ...

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...
