Chromosome-level genome provides novel insights into the starch metabolism regulation and evolutionary history of Tetraselmis helgolandica.

ABSTRACT:

Introduction

Tetraselmis helgolandica is a marine microalga belonging to the Chlorophyta phylum. It is widely distributed in the coastal waters of Asia and is commonly used as aquatic feed. T. helgolandica is characterized by its large size, preference for starch accumulation, low temperature tolerance, presence of flagella, and strong motility. However, research on T. helgolandica is limited, and its genome data remains unavailable.

Objective

We generated a high-quality, chromosome-scale genome of T. helgolandica. Through comparative genomics, we uncovered the genome characteristics and evolutionary history of T. helgolandica. Additionally, by integrating transcriptome data, we elucidated how the light-dark rhythm enhances the high starch production.
