A Novel Isolate of <i>Bacillus cereus</i> Promotes Growth in Tomato and Inhibits <i>Clavibacter michiganensis</i> Infection under Greenhouse Conditions
The need to produce food in a sustainable way to counteract the effects of excessive use of agrochemicals opens the door to the generation of new technologies that are not based on fossil fuels and are less toxic to ecosystems.

| description | The need to produce food in a sustainable way to counteract the effects of excessive use of agrochemicals opens the door to the generation of new technologies that are not based on fossil fuels and are less toxic to ecosystems. Plant growth-promoting bacteria (PGPB) could represent an alternative to chemical biofertilizers and pesticides offering protection for biotic and abiotic stresses. In this work, a bacterial isolate from roots of castor bean (<i>Ricinus communis</i>) was identified and named as <i>Bacillus cereus</i> strain “Amazcala” (B.c-A). This isolate displayed the ability to solubilize inorganic phosphate and produce gibberellic acid (GA3). Moreover, this bacterium provided significant increases in height, stem width, dry weight, and total chlorophyll content in tomato plants. Interestingly, B.c-A also significantly decreased the severity of bacterial canker disease on tomato caused by <i>Clavibacter michiganensis</i> (<i>Cmm</i>) in preventive disease assays under greenhouse conditions. Based on our results, B.c-A can be considered as PGPB and a useful tool in <i>Cmm</i> disease control on tomato plant under greenhouse conditions. |
