Role of Ethylene in Plants
The development of the plants involves the progressive and recessive birth and death of their parts such as shoots, roots, leaves, flowers and buds. The tree shape could be examined by taking into account the numbers of parts that determine the longevity and final outcomes. The outcomes of buds are determined by their location on the tree. While many factors are involve in the regulation of this developmental pattern. Ethylene plays an important role in the co-ordination of all these processes and also plays a central role in the development of the plants (Burg, S. P. (1968).
Ethylene is a gaseous growth factor that is involved in a diverse group of cellular, developmental and stress related processes in plants like it inhibits the cell division, synthesis of

The ACC deaminase bacteria first binds to the seeds or roots surface, while some endophytic bacteria are also found inside the roots of a plant. Then the bacteria synthesize indoleacetic acid (IAA) in response to root exudates that includes an amino acid called tryptophan. The plant cells together this IAA that is synthesized by the bacteria with the endogenous plant IAA that then involved in the cell proliferation and elongation as well as also induces the synthesis of enzyme ACCC synthase. In the next step some of ACC is absorbed and taken up by the ACC deaminase containing bacteria. Then this ACC is converted in to ammonia and α-ketobutyrate and then these both are metabolized by the bacteria. As the level of ACC in the plants is reduced, the amount of ethylene is also reduced. In this way the bacteria acts as a sink for ACC. The interaction of ACC deaminase containing bacteria with the plants increase the plant root and shoot length also increase the biomass and the protection of plants from inhibitory effects of ethylene that is synthesized by a variety of biotic and abiotic
