An amino acid polymorphism in the membrane progesterone receptor alpha protein is tied to female sexual maturity in the large yellow croaker (Larimichthys crocea).

Progesterone is a major steroid hormone of vertebrates, which regulates many different physiological functions. This study reports on a radical amino acid exchange of an aromatic phenylalanine (F) or tyrosine (Y) with an aliphatic leucine (L) in the membrane progesterone receptor alpha protein of large yellow croaker (Larimichthys crocea), one of the important fishery species in the Northwest Pacific Ocean that is now critically endangered due to overfishing. This derived radical exchange is associated in wild Chinese populations with a slower rate of seasonal sexual maturation by the females.

Comparative analysis of the heart histological structure, metabolic enzyme activities and transcriptome profiles of juvenile and adult yellowfin tuna (Thunnus albacares) in the South China Sea.

The yellowfin tuna is a large marine carnivorous fish with high commercial value. It is known for its unique physiological characteristics and holds significant potential for aquaculture. However, research on this species' developmental biology and physiology remains limited, particularly regarding the structural characteristics and functional changes in the developing heart.

Comparative analysis of spleen structure, biochemical parameters, and transcriptome of adult and juvenile yellowfin tuna (Thunnus albacares) in the South China Sea.

As one of the top predators in the ocean, yellowfin tuna possesses physiological characteristics that are highly adapted to its high-speed swimming habits, such as high cardiac output and efficient oxygen uptake and transportation systems, which enable it to swim rapidly various diverse layers of the water for feeding activities. These physiological characteristics are intricately associated with the efficient hematopoietic function of its spleen, which plays a crucial role in maintaining its long-distance migration and sustained physical activity in particular. However, there are fewer studies on the developmental biology and function of the spleen in this species.

Comparative and phylogenetic analyses of the chloroplast genomes of mangrove plants.

Mangrove ecosystems play a crucial role in coastal environment by stabilizing shorelines, reducing erosion, and providing habitat for diverse wildlife. However, there are fewer studies on the genetic management of mangrove plants. In this study, the chloroplast genome of Hibiscus tiliaceus L.

Stability of population genetic structure in large yellow croaker (): Insights from temporal, geographical factors, and artificial restocking processes.

Despite concerns about overfishing and the potential impact of release programs on wild populations, our study of 3116 individuals from 13 wild populations and 2787 individuals from two cultured populations in Zhejiang and Fujian provinces spanning 2008 to 2023 reveals a relatively stable genetic diversity in . Surprisingly, the genetic diversity of wild large yellow croaker populations has remained consistent over the years, suggesting minimal influence from population declines due to overfishing. With the exception of populations in Sansha Bay and Luoyuan Bay, no significant genetic differences were observed among wild populations, indicating a single panmictic genetic population across the East and South China seas.

Molecular cloning and characterization of calmodulin-like protein CaLP from the Scleractinian coral Galaxea astreata.

Optimal temperature and light are both necessary conditions for coral survival. Light enhances calcification, and thermal stress disrupts Ca homeostasis. As calcium is involved in many important metabolic activities, in this study, we cloned the calmodulin-like protein (CaLP) gene of one of the scleractinian corals, Galaxea astreata.
