Temporal and Spatial Expression Analysis of Shoot-Regeneration Regulatory Genes during the Adventitious Shoot Formation in Hypocotyl and Cotyledon Explants of Tomato (CV. Micro-Tom).

ABSTRACT: Enhancing the competence for plant regeneration in tissue culture studies is an important issue not only for efficient genetic transformation of commercial crops but also for the reproducibility of scientific reports. In this study, we investigated optimization of several tissue culture conditions including plant growth regulators, types and ages of explants, culture densities, and plant position in order to improve the competence of adventitious shoot formation of the tomato (Solanum lycopersicum cv. Micro-Tom). In addition, we examined the differential expression of D-type cyclin (CYCD3-1) and several shoot regeneration regulatory genes from hypocotyl and cotyledon explants of tomato during shoot organogenesis.
