Dmrt2b (doublesex and mab-3 related transcription factor 2b) has been revealed to be involved in zebrafish slow muscle development. However, the function of dmrt2a, a paralogue gene of dmrt2b, remains unclear during zebrafish muscle development. Here, we demonstrated that knockdown of dmrt2a resulted in severe developmental defects, and caused downregulation of fast muscle marker myhz-2 and upregulation...
12-Oxophytodienoate reductase (OPR) is a key enzyme in the biosynthesis of jasmonic acid (JA), which plays an important role in plant defense responses. Although multiple isoforms of OPRs have been identified in various annual herbaceous plants, genes encoding these enzymes in perennial woody plants have yet to be fully investigated. In the tea plant, Camellia sinensis (L.), no OPR genes have been...
Sexual size dimorphism has been observed in many cultivable fish species including yellow catfish, in which male fish grow much faster than female fish. Ghrelin is a potent stimulator of pituitary growth hormone (GH) release and known to potentially promote food intake and body weight gain. In order to investigate the molecular mechanism of sexual size dimorphism in yellow catfish (Pelteobagrus fulvidraco),...
Green fluorescent protein (GFP) has been widely used as a molecular marker in modern biological research. Before the recent report of one GFP gene in Branchiostoma floridae, GFP family members were cloned only from other two groups of species: Cnidaria and Copepoda. Here we describe the complete GFP gene repertoire of B. floridae which includes 13 functional genes and 2 pseudogenes, representing the...
Previous studies showed that the vertebrate ABCA subfamily, one subgroup of the ATP-binding-cassette superfamily, has evolved rapidly in terms of gene duplication and loss. To further uncover the evolutionary history of the ABCA subfamily, we characterized ABCA members of two amphioxus species (Branchiostoma floridae and B. belcheri), the closest living invertebrate relative to vertebrates. Phylogenetic...
