Endophytic plant growth promoting rhizobacteria (PGPRs) could replace chemical fertilizers in sustainable agriculture. Unfortunately, they are susceptible to harsh environmental conditions. Here, we proposed a polymeric hydrogel (PMH) consisting of carboxymethyl chitosan, sodium alginate, and calcium chloride for loading protecting endophytic PGPR. This can load PGPRs not only boost its growth-promoting efficiency, but also help them adapt more effectively environments. Using PGPR Ensifer C5 as model bacteria Brasscia napus host, demonstrate that the PMH facilitate colonization apical lateral root primordia regions.
