Changes in respiration of mitochondria isolated from cotyledons of ethylene-treated pea seedlings.

abstract：MAIN CONCLUSION:Plant tissue culture has been used for conservation, micropropagation, and in planta overproduction of some pharma molecules of medicinal plants. New biotechnology-based breeding methods such as targeted genome editing methods are able to create custom-designed medicinal plants with different secondary ...
