Which one of the following statements related to genetic transformation of plants is correct?
1
Negative selection markers need to be expressed only under strong constitutive promoters for development of transgenic plants
2
A transgenic plant containing two linked copies of the transgene in heterozygous condition would segregate in a 3 ∶ 1(transgenic : non‐ transgenic) ratio for the transgenic phenotype on self pollination.
3
Agrobacterium –mediated transfer of T‐DNA into a host plant does not require host plant proteins.
4
In a binary vector system of Agrobacterium tumefaciens, the oncogenes are located on the Helper plasmid.
