Diversification of the aquaporin family in geographical isolated oyster species promote the adaptability to dynamic environments.

Background: The diversified aquaporin (AQP) family that was derived from gene duplication and subsequent functional differentiation play critical roles in multiple physiological processes and in adaptation to the dynamic environments during the evolutionary process. Oysters are a group of bivalve fauna in Mollusca that were widely distributed around the world and show extraordinary adaptation to harsh environments. However, knowledge is lacking with the diversity and evolution of the AQP family in oysters, even in molluscs.

Duplication and subsequent functional diversification of aquaporin family in Pacific abalone Haliotis discus hannai.

Aquaporins (AQPs) are a group of proteins that evolved to mediate specific permeation of water and other small solutes, playing important roles in osmoregulation and nutrition, especially for aquatic animals. Genome-wide characterization of the AQP family in a typical mollusc, Pacific abalone, suggested that tandem duplication and retroduplication led to the dramatic expansion and diversification of AQP genes. Structural analysis indicated that tandem duplicated AQPs showed abnormal characteristics.

Polyploidization and pseudogenization in allotetraploid frog Xenopus laevis promote the evolution of aquaporin family in higher vertebrates.

Background: Aquaporins (AQPs), as members of the major intrinsic protein (MIP) superfamily, facilitated the permeation of water and other solutes and are involved in multiple biological processes. AQP family exists in almost all living organisms and is highly diversified in vertebrates in both classification and function due to genome wide duplication. While some AQP orthologs have been lost in higher vertebrates through evolution.

Metabolomics Adaptation of Juvenile Pacific Abalone Haliotis discus hannai to Heat Stress.

Temperature fluctuation is a key abiotic factor for the growth and survival of Pacific abalone Haliotis discus hannai, particularly during climate change. However, the physiological mechanism underlying the abalones' response to heat stress remains unknown. We sought to understand the metabolic adaptation mechanism of Pacific abalone to heat stress for further analyzing its heat tolerance capacity.

Characterization of 19 polymorphic SSR markers in (Lemnaceae) and cross-amplification in .

Premise Of The Study: Polymorphic microsatellite primers were developed for greater duckweed, (Lemnaceae), to investigate genetic diversity and structure for application in a bioremediation program.

Methods And Results: A total of 401 publicly available . whole-genome shotgun sequences were searched for simple sequence repeat loci of two or more nucleotides.
