Leaf epinasty involves the downward bending of leaves as a result of disturbances in their growth, with a greater expansion in adaxial cells as compared to abaxial surface cells. The co-ordinated anisotropy of growth in epidermal, palisade mesophyll and vascular tissues contributes to epinasty. This phenotype, which is regulated by auxin (indole-3-acetic acid, IAA), controls plant cell division and elongation by regulating the expression of a vast number of genes. Other plant hormones, such as… CONTINUE READING
