Question

Pick up the wrong statement:

• A. Pectinase and cellulase dissolve cell wall.
• B. Some cyanobacteria form symbiotic association with fern Azolla.
• C. Regeneration of cell wall in somatic hybridisation is induced by PEG.
• D. Plants obtained through pollen culture are always haploid.
• E. Shoot regeneration in callus is promoted by cytokinin like BAP.

Answer 1

The correct option is C Regeneration of cell wall in somatic hybridisation is induced by PEG.

Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, somatic hybrid. The formation of the cell wall is then induced using hormones. The cell are then grown into calluses which then are finally grown into plantlets and finally to a full plant, known as a somatic hybrid.

So, option c is the correct option.
