3.3.1 Effect of Plant Genotype on Rhizosphere Microbiome Assembly
ОглавлениеA large number of bacteria associated with the rhizosphere of plants produce phyto-therapeutic compounds that increase the growth of medicinal plants. Rhizosphere microbes of Matricaria chamomilla L., and Calendula officinalis L growing naturally in desert ecosystem showed abundant occurrence of bacteria (gram positive), which is very important for pathogens suppression. A large difference in endophytic bacterial diversity in medicinal plants, i.e., Lamiophlomis rotate, Codonopsis pilosula, and Ephedra sinica was recorded by Li et al. (2008). In contrast, different varieties of microbial groups are present in the soil. About 50 strains of 47 genera Stigmatella (1), Archangium (8), Myxococcus (18), Corallococcus (11), Cystobacter (7), Pyxidicoccus (1), with dominant genera of Corallococcus and Myxococcus. The incessant cropping of Rahmannia glutinossa decreases the productivity of some medicinal plants due to plant–microbe interaction activity in the rhizosphere (Qi et al. 2009). Different medicinal plant–microbe interactions in the rhizosphere is presented in Table 3.2.
