Nodule formation in leguminous plants occur due to (i) Cytokinins produced by invading bacteria. (ii) Auxins produced by plant cell. (iii) Auxins produced by invading bacteria. (iv) Cytokinin produced by plant cell.

Question

Nodule formation in leguminous plants occur due to (i) Cytokinins produced by invading bacteria. (ii) Auxins produced by plant cell. (iii) Auxins produced by invading bacteria. (iv) Cytokinin produced by plant cell., (i) and (ii) only, (i) and (iii) only, (iii) and (iv) only, (ii) and (iv) only

MARKS App · Accepted Answer

During nodule formation the bacteria Rhizobium invades the cortex cells of the host and produces cytokinin which causes bacteria to divide and form a mass called as peribacteriod. At the same time host cell produces auxin. Which causes the cortical cells to enlarge and from nodule.
