Plant development involves the integration of complex network of external and internal signals that respond to the environment and intercellular signals. Confirmed from a fungal pathogen, Gibberella fujikuroi, which causes an unusual seeding in rice, Gibberellins(GAs), are tetracyclic diterpenoid plant hormones necessary for stem elongation, flower induction, germination, and reproduction. Moreover, gibberellin is necessary for flowering response during the day length. also a plant hormone stimulating the overall plant growth, can control the plant growth through signal transfer. Since gibberellin deficiency leads to male sterility and excess of gibberellin partially leads to male sterility, maintaining the gibberellin level is very important. For gibberellin signaling the proper function of F-box protein, SLY1, and a type of E3 ubiquitin-ligase. SCFSLY1 complex is required gibberellin-deficient mutant is useful in for elucidating the action mechanism of gibberellin during the process of plant development, while gibberellin biosynthetic mutant is used to determine gibberellin biosynthetic pathway. Plants are consistently exposed to biological and non-biological stresses during their life cycle. High salt concentration is known to adversely influence metabolic activity and development of plants. This is why plants posses a number of signaling pathways to cope with salinity stress. A plant is restricted in its seed germination and growth when it is in a non-biological stress, such as salinity stress, acid stress and heat stress. In this case, gibberellin can bring the growth restrained by stress and seed germination back to normal. On top of this, the corresponding hormone has an additional effect on the signal transfer process of other hormones that control an immune reaction to biological stress. DELLA protein as a central repressor in gibberellin signaling, is also involved in the regulation of other hormone signalings. It is a nuclear transcriptional regulatory factor which plays a role in the developmental process and the stress response of plants. This paper describes the role of gibberellin with respect to seed germination and the overall plant growth, by extension, as to what effect the corresponding hormone puts on the defense system of a plant exposed to various types of stress.
