In the biocontrol strain Pseudomonas fluorescens CHA0, the Gac/Rsm signal transduction pathway positively controls the synthesis of antifungal secondary metabolites and exoenzymes. In this way, the GacS/GacA two-component system determines the expression of three small regulatory RNAs (RsmX, RsmY, and RsmZ) in a process activated by the strain's own signal molecules, which are not related to N-...

The bacterium Pseudomonas aureofaciens 63-28 is antagonistic to several plant pathogenic fungi, including Pythium spp. The bacterium produced at least four antifungal metabolites active against Pythium ultimum and Phytophthora cryptogea when tested in culture for antifungal activity. Two of these compounds were identified as the novel butyrolactones (Z)-4-hydroxy-4-methyl-2-(1-hexenyl)-2-buteno...

Het verspreiden van desinformatie wordt beschouwd als een bedreiging voor het publieke domein waartegen moet worden opgetreden. Als inderdaad schade teweeg kan brengen aan domein, strafbaarstelling de verspreiding gerechtvaardigd zijn. Zowel in licht artikel 10 EVRM vanuit ultimum remedium-gedachte echter eerst bezien hoeverre inzet op mediawijsheid, tuchtrechtelijke en civielrechtelijke mogeli...

In light of public concerns over the use of pesticides and antibiotics in plant protection and the subsequent selection for spread of resistant bacteria in the environment, it is inevitable to broaden our knowledge about viable alternatives, such as natural antagonists and their mode of action. The genus Pseudomonas is known for its metabolic versatility and genetic plasticity, encompassing pat...

This study aims at identifying the major soil borne pathogens of tomato associated with damping-off in nursery areas. To achieve this, nurseries plant pathology farm our area has been investigated. Samples symptoms were collected and cultured under aseptic conditions. Fungi isolated from diseased stem roots on potato dextrose agar (PDA) medium. Growing colonies fungi purified by single spore hy...
