The study using molecular data from three DNA regions (matK, rbcL, and trnH-psbA) supported the monophyly of Melodinus. The M. cochinchinensis from Vietnam and China are closely related. There are some genetic variations in the sequences of Melodinus cochinchinensis from Belgium versus Asiatic M. cochinchinensis, as well as the phylogenetic position of the species, suggesting the possibility of misidentification of M. cochinchinensis from Belgium.

Bighead catfish, Clarias macrocephalus, is an important species for aquaculture. Nevertheless, information on population variation in their reproductive characteristics and larval growth is limited. This research aimed to evaluate the reproductive performance and larval growth of three bighead catfish broodstock strains collected in Ca Mau (CM) and Hau Giang (HG) provinces (wild strains), and Can Tho (CT, domesticated strain) in the Mekong Delta, Vietnam.

The use of DNA barcodes is a molecular method commonly used for the identification of specimens that are difficult to pinpoint accurately by traditional morphological methods. DNA barcoding uses standard short genomic regions that are universally present in target lineages and has sufficient sequence variation to identify species in the genus.

Loropetalum subcordatum is an endangered species endemic to China that is characterized by narrow distribution, small population size, and delayed fertilization. However, the genetic diversity of the entire extant natural and ex situ populations has not been assessed to date.

Breonadia salicina (Rubiaceae) is a critically endangered plant at the local scale native to southwestern Saudi Arabia. To understand the levels and partitioning of genetic variation across populations and geographical regions of this species, we assessed its genetic diversity using inter-simple sequence repeat (ISSR) markers.

The domestic turkey (Meleagris gallopavo) is an important agricultural species that is largely used as a meat-type bird. Characterizing genetic variation in populations of domesticated species and associating these variation patterns with the evolution, domestication, and selective breeding is critical for understanding the dynamics of genomic change in these species.

S-adenosyl-l-homocysteine hydrolase (SAHH) is the only eukaryotic enzyme capable of S-adenosyl-lhomocysteine (SAH) catabolism for the maintenance of cellular transmethylation potential. Recently, biochemical and genetic studies in herbaceous species have obtained important discoveries in the function of SAHH, and an extensive characterization of SAHH family in even one tree species is essential, but currently lacking.

Distant hybridization can generate transgressive hybrid phenotypes that lead to the formation of new populations or species with increased genetic variation. In this study, we produced an experimental hybrid goldfish (EG) by distant crossing of red crucian carp (Carassius auratus) × common carp (Cyprinus carpio) followed by gynogenesis.

Acipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of numerous microchromosomes and propensity to interspecific hybridization.

For most domestic animal species, including bovines, it is difficult to identify causative genetic variants involved in economically relevant traits. The candidate gene approach is efficient because it investigates genes that are expected to be associated with the expression of a trait and defines whether the genetic variation present in a population is associated with phenotypic diversity.

Formation of the vertebral column is a critical developmental stage in mammals. The strict control of this process has resulted in little variation in number of vertebrae across mammalian species and no variation within most mammalian species.

During the past decades, extensive parts of the Quercus brantii woodlands in the Zagros Mountains declined in size and habitat quality. We aimed to explore the variation of oak woodlands in the southern Zagros Mountains and to assess the vulnerability. We examined 49 plots at different altitudes and aspects, recorded the vascular plant species for tree and herb-layer composition, and collected data on topographic and edaphic factors.

Siberian stone pine (Pinus sibirica Du Tour) is a cone-bearing species with outstanding nutritious seeds, health-supporting properties, and nut oil. Currently, the main volume of pine nuts is harvested in natural forests, which causes damage to ecosystems. The best solution to this problem would be harvesting nuts on special pine nut plantations established on the basis of high-seeding clones. However, it is hampered by the low efficiency of the existing methods for assessing plus-tree productivity.
