Randomized trial examines genome size correlation with cyst size in chrysophyte algae, suggesting novel insights.

This study aims to explore the relationship between genome size and cyst size in chrysophyte algae.
Identified 85 chrysophyte strains from 31 species using nuclear ITS rDNA barcoding
Estimated genome sizes with propidium iodide flow cytometry
Conducted linear regression analysis on log-transformed data of genome size and cyst volume for 54 species.
Observed over a 75-fold variation in genome size (0.15–11.25 pg) within Mallomonas species
Found a strong positive correlation (ρ = 0.626, p < 0.001) between genome size and cyst volume
Demonstrated that cyst size is a better predictor of genome size than cell size in chrysophytes.

Protić et al. (2026) studied this question.
