Transcriptomic analysis reveals key genes and pathways involved in fruit abscission of Epimedium pubescens.

ABSTRACT:

Background

Fruit abscission in Epimedium pubescens is a critical yet underexplored process affecting seed yield and agricultural efficiency. Here, we integrated transcriptomic analyses across three developmental stages (pre-abscission, abscission zone formation, and post-abscission) to unravel the molecular underpinnings of fruit shedding.

Result

We identified 1,009 significant DEGs in the comparison between stage B and stage A, and 1,388 significant DEGs in the comparison between stage B and stage C. Enriched in lignin biosynthesis, starch-sucrose metabolism, and plant hormone signaling pathways. Key lignin-related genes (e.g., COMT, CAD) were upregulated during abscission formation, correlating with enhanced cell wall fortification. Concurrently, dynamic shifts in starch s
