Induced morphogenesis in tissue cultures of Solanum xanthocarpum.

abstract：:In her 1929 essay A Room of One's Own, Virginia Wolf famously wrote, "One cannot think well, love well, sleep well, if one has not dined well." While this popular quote is perhaps not the most inspiring, it is an elegant reminder that food and the cultural practices surrounding food are paramount for our wellbeing. Ho...
