In recent years, metabolism researches using nanomaterials have been focusing on human and animal cells, and therefore very limited data are available about influence of nanomaterials on biosynthesis of secondary metabolites in plant cells. Plants produce different types of secondary metabolites including terpenoids, phenolics, tannins, and alkaloids, which are known to act as vital mediators f...

Plant growth-promoting rhizobacteria (PGPR) are known in various cropping systems to increase plant growth and vigor, as well as induce resistance to pathogens and pests. A commercial soil amendment containing a mixture of two species of Bacillus PGPR (Bacillus subtilis and Bacillus amyloliquefaciens) was evaluated for impact on germination and initial growth of bell pepper plants, efficacy aga...

Basal stem rot disease (BSR) is one of the significant oil palm plant diseases triggered by presence Ganoderma boninense. This poses a major risk in terms production sustainability Southeast Asia, particularly Indonesia, and implicated great economic loss. Therefore, aim this study was to determine antagonistic potential growth-promoting microbes on seedlings infected BSR which involved use fou...

abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

abstract now, it’s completely proved that we can find strains among many strains of each rhizobial group that can also do effective process in plant growth promoting as plant growth hormones production (iaa), in addition of their ability in n2 fixation .therefore, the aim of this research is to determinate the ability of iaa production of some of the indigenous rhizobial strains by two quantita...

Micromonospora is a Gram positive bacterium that can be isolated from nitrogen fixing nodules from healthy leguminous plants, where they could be beneficial to the plant. Their plant growth promoting activity in legume and non-legume plants has been previously demonstrated. The present study explores the ability of Micromonospora strains to control fungal pathogens and to stimulate plant immuni...
