Molecular analysis of photomorphogenesis in tomato

We are interested to decipher the molecular steps involved in photomorphogenesis, using mutants of tomato. We are interested in tomato, as it is a crop plant, and also amenable to genetic analysis.

Of the several facets of photomorphogenesis, we are interested in phototropism in tomato.Our lab is actively engaged in isolating and characterizing phototropic mutants of tomato. We have found that the aurea mutant of tomato is impaired in phototropism and respond sluggishly to unidirectional blue light compared to wild type. (See figure below).
