Expression analysis of Some Stress-Related Genes Induced by Cadmium on Tomato (Solanum lycopersicum L.) Plants

In Vitro Preservation of Transgenic Tomato (Solanum lycopersicum L.) Plants Overexpressing the Stress-Related SlAREB1 Transcription Factor

In vitro preservation of transgenic tomato lines overexpressing the stress-responsive transcription factor SlAREB1 was studied by using slow growth and cryopreservation techniques. Slow growth preservation was performed by using different concentrations of sucrose (0, 100, 200, 300 mm) and abscisic acid (0, 4, 8, 12 μm) in Murashige and Skoog (MS) media, while cryopreservation was conducted by ...

Molecular and biochemical characterization of tomato (Solanum lycopersicum L.) plants cv. Micro-Tom under lead (Pb)-induced stress

Two different Pb concentrations (5 and 10 mg/kg of PbAc2) were used to study the response of Solanum lycopersicum L. cv. Micro-Tom (MT) plants in two vegetative growth phases. Two genes that have been previously reported to be heavy metal inducible genes (superoxide dismutase, SOD, EC 1.15.1.1; and isofl avone reductase, IFR; EC 1.6.4.2) and another one putatively interesting in this fi eld (tr...

Exogenous nitric oxide (NO) ameliorates salinity-induced oxidative stress in tomato (Solanum lycopersicum) plants

Nitric oxide (NO) is involved in numerous physiological and stress responses in higher plants. Tomato is one of the most important vegetable crops in the world and previously it has been reported that salinity induced an oxidative stress affecting its redox and NO homeostasis. Using tomato plant exposed to 120 mM NaCl, it was studied whether the exogenous application of NO could ameliorate the ...

Cloning and Expression Profiling of the Polycomb Gene, Retinoblastoma-related Protein from Tomato Solanum lycopersicum L.

Cell cycle regulation mechanisms appear to be conserved throughout eukaryotic evolution. One of the important proteins involved in the regulation of cell cycle processes is retinoblastoma-related protein (RBR), which is a negative regulator of cell cycle progression, controlling the G1/S transition in plants and animals. In this study, we present the cloning and genomic structure of a putative ...
