Summary Introduction

To analyze: The reason for warmness of mutants that over produces abscisic acid under normal nonstressful conditions.

Concept introduction:

Abscisic acid is the factor responsible for seed dormancy and drought tolerance. During unfavorable conditions, this acid keeps the seed in dormant stage. It suppresses the germination and induces the protein synthesis to avoid dehydration. In well grown plants, during drought the abscisic acid accumulates in leaves. It acts on guard cells and closes the stomata. This prevents water loss by transpiration.
