Identification of Two Common Bottlenose Dolphin () Ecotypes in the Guadeloupe Archipelago, Eastern Caribbean.
Animals (Basel)
January 2025
Institut de Systématique, Évolution, Biodiversité (ISYEB), Muséum National d'Histoire Naturelle, CNRS, Sorbonne Université, EPHE-PSL, Université des Antilles, 75005 Paris, France.
The common bottlenose dolphin () exhibits significant intraspecific diversity globally, with distinct ecotypes identified in various regions. In the Guadeloupe archipelago, the citizen science NGO OMMAG has been monitoring these dolphins for over a decade, documenting two distinct morphotypes. This study investigates whether these morphotypes represent coastal and oceanic ecotypes, which have not been previously identified in the region.

Background: Plant mitochondrial genomes (mitogenomes) exhibit extensive structural variation yet extremely low nucleotide mutation rates, phenomena that remain only partially understood. The genus Gossypium, a globally important source of cotton, offers a wealth of long-read sequencing resources to explore mitogenome and plastome variation and dynamics accompanying the evolutionary divergence of its approximately 50 diploid and allopolyploid species.
Results: Here, we assembled 19 mitogenomes from Gossypium species, representing all genome groups (diploids A through G, K, and the allopolyploids AD) based on a uniformly applied strategy.
Mitochondrial genome structural variants and candidate cytoplasmic male sterility-related gene in sugarcane.
BMC Genomics
January 2025
State Key Laboratory for Conservation and Utilization of Subtropical Agro-Bioresources, Guangxi Key Laboratory of Sugarcane Biology, College of Agriculture, Guangxi University, Nanning, 530004, China.
Background: Sugarcane is a crucial crop for both sugar and bioethanol production. The nobilization breeding and utilization of wild germplasm have significantly enhanced its productivity. However, the pollen sterility in Saccharum officinarum restricts its role to being a female parent in crosses with Saccharum spontaneum during nobilization breeding, resulting in a narrow genetic basis for modern sugarcane cultivars.

Article Synopsis
- Pomacea canaliculata is an invasive aquatic species with varying dietary habits and intestinal microbiota across different habitats (pond, river, ditch).
- This study utilized gene sequencing and metabolomics to analyze intestinal samples, revealing the highest dietary diversity in ditches and significant differences between male and female diets in ponds.
- The findings indicate that changes in diet affect intestinal microbiota and metabolic pathways, helping to explain how P. canaliculata adapts physiologically to diverse environments, which is crucial for understanding its impact on aquatic ecosystems.
A multidimensional pan-cancer analysis of NDUFA4L2 and verification of the oncogenic value in colon cancer.

NADH dehydrogenase (ubiquinone) 1 alpha subcomplex, 4-like 2 (NDUFA4L2) protein is located in the mitochondria and can regulate cell proliferation. Some studies have shown that the high NDUFA4L2 expression is linked with poor prognosis and cancer progression in various patients with cancers. However, the correlation between NDUFA4L2 and pan-cancer is unknown.
