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