摘      要：Most of the cereal crops are widely cultivated to fulfil the humans food *** changing climate scenario,the intensity of drought stress is continuously increasing that is adversely affecting the growth and yield of cereal *** the cereals can tolerate moderate drought to some extent,but mostly they are susceptible to severe drought *** biosynthesis of ethylene under drought stress has been *** scientists observed that inoculation of 1-aminocyclopropane-1-carboxylate(ACC)deaminase producing plant growth promoting rhizobacteria(PGPR)is an efficacious tool to overcome this *** PGPR secrete ACC deaminase which cleavage the ACC into the compounds,other than ***,secretion of growth hormones also play imperative role in enhancing the growth of the cereals under limited availability of *** addition,the use of biochar has also been recognized as another effective amendment to grant resistance against *** application improves the soil physiochemical attributes i.e.,porosity,nutrients retention and water holding capacity which decrease the loss of water and increase its *** recent era,the idea of coapplication of ACC deaminase producing PGPR and biochar is becoming popular which might be more efficient to use water under drought *** aim of current review is to combine the facts and understanding of this novel idea to grant maximum resistance to crops against drought *** scientists have observed significant improvement in yield of cereal crops by combined use of ACC deaminase producing PGPR and ***,more research is suggested for deep understanding of complex synergistic mechanism of ACC deaminase activity in combination with biochar.
