Gibberellins’ Cross Talk and Signal Transduction in Plant Stress Response

AbstractPhytohormones play significant roles in plants for its growth and development. These phytohormones have been identified to regulate stress tolerance in plants. Gibberellic acid is one such phytohormones which carries out several important roles, GA crosstalk with many other phytohormones like ethylene, jasmonic acid, brassinosteroids, strigolactones which further leads to increased tolerance to stresses such as drought, salinity, extreme temperature, etc. This chapter focuses in the signalling mechanism of GA along with its crosstalk with other related phytohormones in different plants.KeywordsPhytohormonesGibberellic acidCrosstalk; Stress
