Distinct organ-specific and temporal expression profiles of auxin-related genes during mango fruitlet drop.

In mango, fruitlet abscission initiates with a decrease in polar auxin transport through the abscission zone (AZ), triggered by ethylene. To explore the molecular components affecting this process, we initially conducted experiments with developing fruitlet explants in which fruitlet drop was induced by ethephon, and monitored the expression patterns of distinct indole-3-acetic acid (IAA)-related genes, comparing control vs. ethephon-treated pericarp and AZ profiles.

Inactivation of Snt2, a BAH/PHD-containing transcription factor, impairs pathogenicity and increases autophagosome abundance in Fusarium oxysporum.

The soil-borne, asexual fungus Fusarium oxysporum f.sp. melonis (FOM) is a causal agent of muskmelon wilt disease.
