Post-transcriptional regulation dominates protein biosynthesis in <i>Landoltia punctata</i> under biogas slurry stress.

ABSTRACT:

Introduction

Duckweed represents a promising alternative protein source, yet enhancing its protein content remains essential for large-scale applications. This study investigated how high nitrogen and phosphorus stress from biogas slurry affects protein accumulation in Landoltia punctata and explored the underlying molecular regulatory mechanisms.

Methods

L. punctata were cultivated in 1/5 strength Hoagland medium supplemented with 0-5% pig farm biogas slurry. The experimental groups showing the highest (4%) and lowest (0%) protein content were selected for integrated transcriptomic and proteomic analyses. Differentially expressed genes (DEGs) and proteins (DEPs) were identified and functionally characterized.

Results

Biogas slurry treatments significantly incr
