An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite . The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (, , , and a non-inoculated control) in the presence or absence of with five replicates. The following characteristics were evaluated after 270 days of mycorrhization and 170 days of inoculation: height, number of leaves and tillers, fresh mass of aerial and subterranean parts, dry mass of aerial parts, foliar area, nutritional content, mycorrhizal colonization, AMF sporulation, and the number of galls, egg masses, and eggs. The results indicated a significant interaction between the treatments for AMF spore density, total mycorrhizal colonization, and nutrient content (Zn, Na, and N), while the remaining parameters were influenced by either AMF or nematodes. Plants inoculated with or exhibited greater growth than the control. Lower N content was observed in plants inoculated with AMF, while Zn and Na were found in larger quantities in plants inoculated with . Fewer galls were observed on mycorrhized plants, and egg mass production and the number of eggs were lower in plants inoculated with . Plants inoculated with showed a higher percentage of total mycorrhizal colonization in the presence of the nematode. Therefore, the association of micropropagated alpinia plants and enhanced tolerance to parasitism by .

Soil salinization adversely impacts plant and soil health. While amendment with chemicals is not sustainable, the application of bioinoculants suffers from competition with indigenous microbes. Hence, microbiome-based rhizosphere engineering, focussing on acclimatization of rhizosphere microbiome under selection pressure to facilitate plant growth, exhibits promise.

Citrus black spot (CBS), caused by , is an important fungal disease of citrus. Higher CBS severity has been associated with infections at the young and green stages of fruit. The length of the fruit susceptibility period may be influenced by the amount of inoculum and the climate of the citrus growing region.

The effects of rhizosphere microorganisms on plant growth and the associated mechanisms are a focus of current research, but the effects of exogenous combined inoculation with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) on seedling growth and the associated rhizosphere microecological mechanisms have been little reported. In this study, a greenhouse pot experiment was used to study the effects of single or double inoculation with AM fungi () and two PGPR ( sp., sp.

Unlabelled: Clubroot, caused by , is a globally pervasive soil-borne disease that poses a significant challenge primarily in cruciferous crops. However, the scarcity of resistant materials and the intricate genetic mechanisms within cabbage present major obstacles to clubroot resistance (CR) breeding. In our previous research, we developed an Ogura CMS cabbage variety, "17CR3", which harbors the gene, crucial for CR.

The microbiota, a component of the plant holobiont, plays an active role in the response to biotic and abiotic stresses. Nowadays, with recurrent drought and global warming, a growing challenge in viticulture is being addressed by different practices, including the use of adapted rootstocks. However, the relationships between these practices, abiotic stress and the composition and functions of the rhizosphere microbiota remain to be deciphered.
