Epiphytic cyanobacteria on Chara vulgaris are the main contributors to N2 fixation in rice fields

Article Abstract:

The distribution of nitrogenase activity in the rice-soil system and the contribution of epiphytic cyanobacteria on rice plants and other macrophytes to this activity are analyzed in two locations in the rice fields of Valencia, Spain. The results indicate that the macrophyte Chara vulgaris, which is usually considered a weed in the context of rice cultivation, may help maintain soil N fertility in the rice field ecosystem.

NorM an erwinia amylovora multidrug efflux pump involved in invitro competition with other epiphytic bacteria

Article Abstract:

Erwinia amylovora uses blossoms, which are important sites for infection, as the main route for infection with natural openings or wounds to gain entry into a plant. A NorM mutant was created to study the effects of promoter activity and it was found that E. amylovora could use NorM for successful competition with other epiphytic microbes to enter high population densities.

Insecticidal Bacillus thuringiensis silences Erwinia carotovora virulence by a new form of microbial antagonism, signal interference

Article Abstract:

The Bacillus thuringiensis was studied to know more about this phenomenon. It was found that Bacillus thuringiensis suppressed the quorum-sensing-dependent virulence of plant pathogen Erwinia carotovora through a form of signal interference and microbial antagonism.
