Filamentous Cercospora fungi are resistant to photosensitizing compounds that generate singlet oxygen. C. nicotianae photosensitizer-sensitive mutants were restored to full resistance by transformation with SOR1 (Singlet Oxygen Resistance 1), a gene recovered from a wild-type genomic library. SOR1 null mutants generated via targeted gene replacement confirmed the requirement for SOR1 in photose...

Five novel isoquinoline alkaloids (+)-N-(methoxylcarbonyl)-N-nordicentrin (1), (+)-N-(methoxylcarbonyl)-N-norpredicentrine (2), (+)-N-(methoxylcarbonyl)-N-norbulbodione (3), and (+)-N-(methoxylcarbonyl)-N-norisocorydione (4), and (+)-8-methoxyisolaurenine-N- oxide (5) were isolated, together with one known compound, (+)-N-(methoxylcarbonyl)- N-norglaucine (6), from a 70% EtOH extract of the bar...

Tomato cultivation has a great worldwide interest. The quality of tomato fruit is economic and health importance. Being rich in water generally stored at 4 °C, tomatoes risk rapid infection. This work was interested isolating studying pathogenic fungi fruit. isolations subcultures were carried out on the PDA medium. Morphological characterization identified 5 Solanum lycopersicum fruits: Altern...

As an ornamental plant, Fatsia japonica has been widely used in gardens. From April 2021 to 2022, a disease that caused the wilting and root rot of F. large area was observed, which eventually led plants dying, while leaves did not fall off. This greatly reduced landscape effect plants. An oomycete species isolated from roots infected colony morphology slightly radial stellate, aerial mycelium ...
