A new species of the genus is described based on morphological comparisons and molecular analyses from specimens of a subterranean tributary of the Hongshui River, Lingyun County, Baise City, and a cave in Jinya Township, Fengshan County, Hechi City, Guangxi, China. Both morphological and molecular data support the validity of The new species can be distinguished from congeners by the following combination of characteristics: whole body except for head and area between pectoral-fin and pelvic-fin origin sparsely covered with minute scales; barbels elongate; five or six branched pectoral-fin rays and four branched pelvic-fin rays; vertebrae 4+42. Maximum-likelihood and Bayesian-inference phylogenetic trees exhibited congruent topological structures, exhibiting high node support for the monophyly of (BPP = 1; BS = 100), which was clustered with the other congeners.

In the context of scarce metal resources, the one-step separation and recovery of high-value copper metal ions from secondary resources is of significant importance and presents substantial challenges. This study identified a Zn-based triazole MOF (Zn(tr)(OAc)) with accessible and noncoordinated terminal hydroxyl groups within its framework. The Zn(tr)(OAc) surpasses most currently reported Cu-specific MOF adsorbents regarding adsorption capacity and Cu selectivity.

The GIBBERELLIN INSENSITIVE DWARF1 (GID1) gene encodes a receptor integral to Gibberellic acid (GA) signaling, which is pivotal for plant growth, development, and stress responses. Until now, GID1 genes have not been documented in mango. In this research, the mango (Mangifera indica) genome yielded four GID1 homologous genes, and this study focuses on the research of MiGID1A and MiGID1B genes.

Tannins play key roles in regulating ecological processes within mangrove ecosystems, but the structures of mangrove condensed tannins (CT) and hydrolysable tannins (HT), as well as their antioxidant and antibacterial activities, are not well understood. In this study, MALDI-TOF MS was used to analyze the structural components of oligomers and polymers in phenolic extracts from Kandelia obovata, Aegiceras corniculatum, and Sonneratia apetala. Results identified two primary structural units: procyanidins (PC) and prodelphinidins (PD), with mass-to-charge ratios of 288 Da and 304 Da, respectively, and a 16 Da interval indicating differences in hydroxylation.

Global warming causes the release of dioxin-like deposits and increases geographical migration, increasing the risk of exposure for humans and animals. In this experiment, we used CYP1A transgenic zebrafish Tg (cyp1a: mCherry) and liver fluorescent transgenic zebrafish Tg (fabp10: Ps Red) as an animal model and exposed to 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD) at 26 °C and 30 °C, respectively. Morphological changes, histological changes, transcriptome and related genes expression were detected.
