1. A recombinant protein for use in a liquid culture medium for photo-autotrophic micropropagation of Cannabis sativa L., the recombinant protein comprising:
an Arabinogalactan protein and/or a plant transcription factor associated with plant growth and development, and
a cell penetrating peptide sequence and a nuclear localization signal, wherein said nuclear localization signal is encoded by the peptide sequence SEQ ID NO 1,
wherein said cell penetrating peptide sequence comprising a sequence of 7 to 25 arginines forming a poly-arginine transduction domain,
wherein said plant transcription factor comprises AP2-like ethylene-responsive transcription factor BBM from Arabidopsis thaliana, or an analog to said AP2-like ethylene-responsive transcription factor BBM from Arabidopsis thaliana, wherein said analog is codon-optimized for a host species.
