Article Synopsis
- Recognition of the intron branchpoint in spliceosome assembly is crucial for mRNA structure and quantity, involving a branchpoint sequence motif that varies across eukaryotic genomes.
- SF1 and QKI proteins compete for recognition of a specific intron branchpoint sequence (ACUAA), where SF1 promotes exon inclusion while QKI represses it, affecting splicing outcomes.
- The findings suggest that QKI acts as a splicing repressor by blocking SF1 binding at dual branchpoints, indicating a co-evolution of branchpoint sequences for precise regulation of gene expression in diverse organisms.
Article Synopsis
- - This study analyzes levels of gamma-emitting radionuclides and various metals in sediments from the Ankobra, Pra, and Volta estuaries in Ghana, revealing enrichments in the Ankobra and Pra basins due to artisanal gold mining.
- - The concentrations of radionuclides were consistent with those typically found in the Earth's crust, and no definitive conclusions were drawn regarding their enrichment from gold mining activities; however, the study noted a transfer of radium from sediments to water.
- - The different patterns of metal enrichment in the estuaries were explored through various methods, indicating that the observed increases in metals like arsenic and copper are likely linked to iron-rich compounds from sulfide ores transported by rivers and deposited
Article Synopsis
- The research examined sediment settling and accumulation in Tema Harbour, Ghana, using sediment traps and core analyses over a 12-week period.
- The study found that settling fluxes (SFs) were significantly higher than sediment accumulation rates (SARs), suggesting that sediment resuspension is a key process in this coastal area.
- Various methods, including the Pb-based TERESA model, were used to provide insights into sediment dynamics, revealing potential sustainability challenges due to sediment accretion rates of 1.7-3 cm per year.
Phosphogypsum (PG) has been usually applied as Ca-amendment to reclaim sodic soils such as those in the marshland area of Lebrija (SW Spain). This work aimed at the effects of PG amendments on the uptake of trace-elements by tomato and its implications for food safety. A completely randomized experiment was performed using a representative soil from Lebrija in a greenhouse involving six replicates and four PG treatments equivalent to 0, 20, 60, and 200 Mg ha(-1).
