Objective: The remarkable adaptability to the environment, high growth rate, meat with good taste and aroma, and ornamental appearance of the Pradu Hang Dam (PDH) and Samae Dam (SD) chickens make them valuable for improvement of poultry production to enhance food security. However, despite their close phenotypic similarity, distinct classification of PDH and SD chickens remains controversial. Thus, this study aimed to clarify genetic origins and variation between PDH and SD chickens, genetic diversity and structures of PDH and SD chickens.

- - Hybrid sterility in catfish occurs due to differences in parental genomes affecting meiosis, which is crucial for reproduction.
- - The study focused on bighead catfish and North African catfish, analyzing their genome divergence and meiotic behavior to understand sterility in their male hybrids.
- - Results indicated that significant differences in satellite DNA (satDNA) between the parent species are likely responsible for meiotic failure, rather than differences in chromosome numbers.
Article Synopsis
- The North African catfish (Clarias gariepinus) is important for aquaculture and food security, but closed breeding practices have reduced its reproductive performance, likely due to inbreeding depression.
- A study assessed the genetic diversity of catfish populations in Thailand using microsatellite genotyping and mitochondrial DNA sequencing, revealing low inbreeding coefficients and significant genetic diversity across three populations.
- The findings suggest that introducing new, well-documented populations into breeding programs could enhance genetic improvement and productivity of the North African catfish.
The thermal stress caused by global climate change adversely affects the welfare, productivity, and reproductive performance of farm animals, including chickens, and causes substantial economic losses. However, the understanding of the genetic basis of the indigenous chicken adaptation to high ambient temperatures is limited. Hence, to reveal the genetic basis of thermal stress adaptation in chickens, this study investigated polymorphisms in the heat shock protein 70 (HSP70) and HSP90 genes, known mechanisms of cellular defense against thermal stress in indigenous and local chicken breeds and red junglefowls in Thailand.

Although DNA barcoding facilitates molecular identification and phylogenetic analysis of species, its availability in clariid catfish lineage remains uncertain. In this study, DNA barcoding was developed and validated for clariid catfish.
