Effects of <i>Vibrio parahaemolyticus</i> on physiology and metabolism of <i>Thalassiosira weissflogii</i> in the co-culture system.

ABSTRACT: Diatoms are crucial primary producers in the marine environment, and their interactions with bacteria exert an important role in the ecosystem. There has been scarce research exploring how diatoms adapt to algal-bacterial environments. In this study, we investigated the physiological and transcriptional distinctions of Thalassiosira weissflogii when grown alone (axenic) and with the bacteria Vibrio parahaemolyticus (co-culture). Although the bacteria did not significantly impact the growth of T. weissflogii, they did affect its photosynthetic efficiency and pigment biosynthesis. The balance of carbon and nitrogen metabolism, as well as energy pathways, including the tricarboxylic acid cycle and glycolysis, was also disrupted. T. weissflogii might be capable of m
