In Vitro Selection of Calli for Salt Tolerance in Tomato (Solanum lycopersicum L.)

The Solanum lycopersicum WRKY3 Transcription Factor SlWRKY3 Is Involved in Salt Stress Tolerance in Tomato

Salinity threatens productivity of economically important crops such as tomato (Solanum lycopersicum L.). WRKY transcription factors appear, from a growing body of knowledge, as important regulators of abiotic stresses tolerance. Tomato SlWRKY3 is a nuclear protein binding to the consensus CGTTGACC/T W box. SlWRKY3 is preferentially expressed in aged organs, and is rapidly induced by NaCl, KCl,...

In-Vitro Organogenesis in Tomato (Solanum Lycopersicum) Using Kinetin

This research was undertaken for optimizing simple and reproducible protocol on indirect regeneration in tomato using kinetin. The effect of kinetin for efficient callus production was studied and its results were interpreted. Hypocotyls and cotyledons were used as explants and effect on callus derived regeneration was greatly influenced by addition of kinetin in media. The individually positio...

Comparative study of salt stress-induced physiological and molecular responses in tomato (Solanum lycopersicum L.)

Cold tolerance in Osmotin transgenic tomato (Solanum lycopersicum L.) is associated with modulation in transcript abundance of stress responsive genes

Our containment trials have established cold tolerance in Nicotiana tabacum osmotin (Nt Osm) transgenic tomato (Solanum lycopersicum L. cv. Pusa Ruby). Though, the stress tolerance mechanisms have been studied at physio-biochemical levels, molecular mechanisms underlying the tolerant response are still not well studied. Therefore, quantitative transcript expression of Osmotin and other stress r...

Identification and characterization of histone deacetylases in tomato (Solanum lycopersicum)

Histone acetylation and deacetylation at the N-terminus of histone tails play crucial roles in the regulation of eukaryotic gene activity. Histone acetylation and deacetylation are catalyzed by histone acetyltransferases and histone deacetylases (HDACs), respectively. A growing number of studies have demonstrated the importance of histone deacetylation/acetylation on genome stability, transcrip...
