The high-quality genome of Bellamya aeruginosa reveals the molecular mechanisms underlying its remarkable stress resistance.

ABSTRACT:

Background

Bellamya aeruginosa belongs to the family Viviparidae and is widely distributed in freshwater ecosystems in Asia. This species is resilient to thermal stress and can survive in polluted waters and consequently has been widely studied as a sentinel species for assessing ecosystem risk. To gain resources to study how B. aeruginosa adapts to harsh environments at the molecular level, we assembled a high-quality genome of this species and compared responses in transcriptome sequencing following exposure to wastewater, heat stress, and cold stress.

Results

We assembled a pseudo-chromosome genome for B. aeruginosa (1.2 Gb, 8 chromosomes) through the integration of multiple sequencing strategies. Comparative genomic analyses demonstrated that genes for the expansion of t
