To obtain virus - free healthy plants from a diseased one by tissue culture techinique, which part/parts of the diseased plant will be taken?
Apical meristem only
Palisade parenchyma
Both apical and axillary meristems
Epidermis only
As learnt
Both apical and axillary meristems are free of virus for the healthy plant cultivation because of strong interferon activity in this region. These tissue form a protective impermeable covering around themselves, which s non-penetrable by any pathogen. Hence, these tissue are used in the production of disease-free plants by tissue culture.
