Abstract

See full text

Plant cell fate and development is altered by treating cells with cellular reprogramming factors. Embryogenesis inducing morphogenic developmental genes are used as cellular reprogramming factors, specifically comprising polypeptides or polynucleotides encoding gene products for generating doubled haploids or haploid plants from gametes. Maize microspores treated by contacting the isolated cells with an exogenous purified, recombinant embryogenesis inducing morphogenic developmental gene polypeptide results in embryogenesis. The gametes of a maize plant develop into embryoids when transformed with a genetic construct including regulatory elements and structural genes capable of acting in a cascading fashion to alter cellular fate of plant cells. Developmental morphogenic proteins expressed from a genetic construct are used for ex situ treatment methods and for in planta cellular reprogramming.
