The field of budding yeast research has long been empowered by the vast array of genetic tools and community resources available. Rescue by mating is one useful tool that entails mating of meiotic spores directly post-germination. This minimal cell division mating process facilitates mating based screens studying the effects of otherwise haploid lethal gene deletions. In this study, we describe the successful application of rescue by mating across two different Saccharomyces species: S. cerevisiae and S. uvarum. This novel inter-species tool enables studies on the evolution of essential genes within the broader Saccharomyces genus.

Unlocking the Forgotten Dimension of Biodiversity: A Scalable Genetic Diversity Index for Multi-Species Analysis
Conservation strategies and biodiversity assessments have long prioritized taxonomic metrics such as species richness and endemism, often neglecting intraspecific genetic diversity, a key driver of population adaptability and long-term resilience. Here, we present a scalable framework for quantifying and mapping multi-species genetic diversity using publicly available DNA sequence data. By calcula...

Comprehensive molecular impact mapping of common and rare variants at GWAS loci
Deep learning sequence to function models can predict the molecular effects of genetic variants, but their predictions are limited to the cell types and assays they are trained on. Here we describe DNACipher, a deep learning model that predicts the effects of genetic variants across diverse biological contexts-including those not directly measured. DNACipher takes 196 kb of genome sequences as inp...

Establishing a DNA reference library for the identification of elasmobranchs in the Indian Ocean using Oxford Nanopore Sequencing
Elasmobranchs, comprising sharks and rays, are among the most threatened species globally. The first elasmobranchs were added to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 2002. Since then, the number of species listed has increased to 151, highlighting the urgent conservation challenges faced by these species. In Sri Lanka, where over 100 specie...

Isolation of Cyclotide Gene from Solanaceae Family and Its Bioinformatics Analysis
Abstract: Cyclotides are highly tolerant of sequence variability, aside from the conserved residues forming the cystine knot. Cyclotides have attractive natural movement capabilities including cytotoxicity, harmfulness to HIV, antimicrobials, insecticides, uterine contraction and inhibition of proteases, making them very important in pharmacy and horticulture. The medicinal cyclotides may be able ...

Leech Speciation and Detection of Hirudin Gene among the Leech Population in Asejire Oyo State, Nigeria
Leeches are segmented, parasitic and sanguivorous worms of the family Hirudinae and phylum Annelida. Various ailments have been treated with them since ancient times. Recent evidence has established the presence of over 100 medicinally useful bioactive substances in their saliva. Based on the therapeutic properties of the substances, they have been used in different areas of medical care and most ...

Natural variation in phospholipase IPLA2-VIA contributes to starvation sensitivity in Drosophila melanogaster
Resistance to starvation is a classic complex trait where genetic and environmental variables can greatly modify an animals ability to survive without nutrients. Genetic analyses in Drosophila have shown that starvation resistance is highly polygenic with different genetic architectures in different mapping populations. In this study we sought to dissect the genetic basis of starvation resistance ...

The Insertion of an ATTTC Repeat in an Alu Element Hyperactivates a Primate-Specific Neurodevelopmental Enhancer in Spinocerebellar Ataxia Type 37
Alu are evolutionarily very old primate-specific interspersed repeat elements that constitute ~11% of the human genome. They are a source of short tandem repeats (STRs), which often expand in size and originate inherited neuromuscular and neurodegenerative disorders. How expanded STR insertion mutations within Alu STRs culminate in disease remains unknown. Here we report an Alu STR located in an i...

Abundant Parent-of-origin Effect eQTL in Humans: The Framingham Heart Study
Parent-of-origin effect (POE) is a phenomenon whereby an allele's effect on a phenotype depends both on its allelic identity and parent from whom the allele is inherited, as exemplified by the polar overdominance in the ovine callypyge locus and the human obesity DLK1 locus. Systematic studies of POE of expression quantitative trait loci (eQTL) are lacking. In this study we use trios among partici...

Impact of trait measurement error on quantitative genetic analysis of computer vision derived traits
Background: Quantitative genetic analysis of image- or video-derived phenotypes is increasingly being performed for a wide range of traits. Pig body weight values estimated by a conventional approach or a computer vision system can be considered as two different measurements of the same trait, but with different sources of phenotyping error. Previous studies have shown that trait measurement error...
