The beneficial roles of different cyanobacterial strains on plants

Cyanobacterial strains	Plant	Beneficial role	Reference
Aphanothece sp	Tomato	Amplified uptake of nitrogen, phosphorus, and potassium by 185.17%, 119.36%, and 78.04%, respectively	(Mutale-Joan et al. 2020)
Anabaena laxa	Chickpea	50 % higher grains yield	(Bidyarani et al. 2015)
Anabaena sp., Anabaena doliolum, Nostoc carneum and Nostoc piscinale	Maize	Yields were increased with 20–30% increases in all inoculated treatments	(Prasanna et al. 2016)
Nostoc muscorum	Barley	Increased in proteins (45.95%), amino acids (39.13), and nutrient content [N (28.4%), K (24.3%), Ca (12.9%), Mg (29.06%), and Fe (13.8%)	(Abo-Shady et al. 2018)
Nostoc muscorum	Broad bean	Induced growth parameters of root length (30%), shoot length (44%), root fresh weight (2-fold), shoot fresh weight (1.5-fold), root dry weight (67%), and shoot dry weight (1.6-fold)	(Osman et al. 2020)
Aphanothece sp	Tomato	Root and shoot lengths of the plant were significantly developed by 112.65% and 53.70%, respectively	(Mutale-Joan et al. 2020)
Arthrospira Platensis	Tomatoes and peppers	Induced shoot dry weight by 1.4-fold in both species of plants, while the positive effects on root weight were much more in tomatoes (2.30-fold) than in peppers (67%)	(Elarroussi et al. 2016)
Anabaena laxa	Pea	Increased the yield by up to 39% and the protein content by 11%	(Prasanna et al. 2017)
