Production of ethylene by excised segments of plant tissue prior to the effect of wounding.

abstract：MAIN CONCLUSION:Andean tomatoes differed from the wild ancestor in the metabolic composition and the expression of genes related with mitochondrial functions, and environmental stresses, making them potentially suitable for breeding programmes. Traditional landraces or "criollo" tomatoes (Solanum lycopersicum L.) from ...
