NOVELTY – Producing genetically modified plants involves producing an expression vector or cloning vector or plasmid having sequence 60% similarity to nucleobases (SEQ ID NO: 1). An inducible promoter and a terminator are linked to vector. The vector is integrated with genome of plant cell. Plant hormone e.g. 0.5-10% ethylene is also utilized during producing genetically modified plants. (Sequences not defined here may be found at ftp://ftp.wipo.int/pub/publishedpct sequences/publication). USE – Method for producing genetically modified plants such as monocot plant or dicot plant e.g. sugarcane, tobacco, soy, corn, rice and wheat for controlling ethylene (all claimed). ADVANTAGE – The method enables to produce genetically modified plants in an efficient manner. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is included for a recombinant DNA vector, which is provided for forming amino acids (SEQ ID NO: 2).
