Azospirillum lipoferum

Maize

Increase the amount of soluble sugar, free amino acids, and

proline content. Root length, shot fresh weight, shoot dry

weight, root fresh weight, and root dry weight are all affected.

Grover et al. (2021)

Bacillus spp.

Maize

Proline, carbohydrates, and free amino acids accumulate more,

and electrolyte leakage is reduced. It reduces the antioxidant

enzyme’s activity (catalase, glutathione peroxidase)

Abdelaal et al. (2021)

Pseudomonas putida

Soybean

The level of abscisic acid and salicylic acid decreases and the

content of jasmonic acid increases.

Skz et al. (2018)

Bacillus amyloliquefaciens

Wheat

Transcript level-mediated homeostasis increases.

Safdarian et al.

(2019)

Pseudomonas putida

Cicer arietinum L.

Accumulation of osmolyte, scavenging of ROS ability

increases.

Tiwari et al. (2016)

Azospirillum sp.

Lettuce

Ascorbic acid, chlorophyll content and aerial biomass,

increases.

Fascigleone et al.

(2015)

Azospirilum brasilense

Wheat

Crop yield and proline level increased. Simultaneously

decreased stomatal conductance, and relative soil water content.

Trichoderma

Rice

Delay response against drought stress

Khadka & Uphoff

(2019)

Pseudomonas libanensis and

Pseudomonas reactans

Brassica oxyrrhina Increased pigment content, plant growth and decreased proline

and malondialdehyde content in leaves.
