Wilding
Definition:
(n.) A wild or uncultivated plant; especially, a wild apple tree or crab apple; also, the fruit of such a plant.
(a.) Not tame, domesticated, or cultivated; wild.
Example Sentences:

(9) Genetic regulation of the ilvGMEDA cluster involves attenuation, internal promoters, internal Rho-dependent termination sites, a site of polarity in the ilvG pseudogene of the wild-type organism, and autoregulation by the ilvA gene product, the biosynthetic L-threonine deaminase.
(10) In contrast, strains carrying the substitutions Ile-30----Phe, Gly-33----Leu, Gly-58----Leu, and Lys-34----Val and the Lys-34----Val, Glu-37----Gln double substitution were found to possess a coupled phenotype similar to that of the wild type.
