Hence, it has wide applicability across a spectrum of neuroscience research, ranging from the study of neural circuits and behavior, to preclinical drug development and screening.The genotype-phenotype link is a major research topic in the life sciences but remains highly complex to disentangle. Part of the complexity arises from the number of genes contributing to the observed phenotype. Despite the vast increase of molecular data, pinpointing the causal variant underlying a phenotype of interest is still challenging. In this study, we present an approach to map causal variation and molecular pathways underlying important phenotypes in pigs. We prioritize variation by utilizing and integrating predicted variant impact scores (pCADD), functional genomic information, and associated phenotypes in other mammalian species. We demonstrate the efficacy of our approach by reporting known and novel causal variants, of which many affect non-coding sequences. Our approach allows the disentangling of the biology behind important phenotypes by accelerating the discovery of novel causal variants and molecular mechanisms affecting important phenotypes in pigs. This information on molecular mechanisms could be applicable in other mammalian species, including humans.Improved reproductive performance in buffaloes can be achieved by understanding the basic mechanism governing the embryonic attachment and feto-maternal communication. Considering this, trascriptomic profiling and integrative analysis of long intergenic non-coding RNAs were carried out in the uterine caruncles of pregnant and non-pregnant buffaloes. Transcriptome data of pregnant and non-pregnant uterine caruncles after quality control was used to perform the analysis. Total of 86 novel lincRNAs expressed in uterine caruncular tissues were identified and characterized. Differential expression analysis revealed that 447 mRNAs and 185 mRNAs were up- and down- regulated, respectively. The number of up- and down- regulated lincRNAs were 114 and 13, respectively. Of the identified 86 novel lincRNAs, six novel lincRNAs were up-regulated in the pregnant uterine caruncles. GO terms (biological process) and PANTHER pathways associated with reproduction and embryogenesis were over-represented in differentially expressed genes. Through miRNA interaction analysis, interactions of 16 differentially expressed lincRNAs with mi-RNAs involved in reproduction were identified. This study has provided a catalogue of differentially expressed genes and novel regions previously unknown to play a significant role in buffalo reproduction. The results from the current study extends the buffalo uterine lncRNAs database and provides candidate regulators for future molecular genetic studies on buffalo uterine physiology to improve the embryo implantation and successful completion of pregnancy.DGAT2 (acyl CoAdiacylglycerol acyltransferase 2) is a key and rate-limiting enzyme that catalyzes the final step of triglyceride (TG) synthesis. In this study, hybrid tilapia were generated from Nile tilapia (♀) and blue tilapia (♂) crossing. The TG content levels in the liver of these tilapia were measured. The results showed that the TG content was higher in the hybrid tilapia. In addition, protein and mRNA expression levels in the tilapia livers were determined. Higher hepatic mRNA and protein expression of DGAT2 in the hybrid fish was found. learn more A luciferase reporter assay with HEK293T cells revealed that miRNA-19a-5p targeted the 3’UTR of DGAT2, suggesting a direct regulatory mechanism. Using qRT-PCR, we found that DGAT2 mRNA levels had a negative correlation with miRNA-19a-5p expression in Nile tilapia and hybrid. Taken together, these findings provide evidence that miRNA-19a-5p is involved in TG synthesis in the regulation of lipid metabolism in tilapia.The WRKY transcription factors is one of the largest families of transcription factors (TFs) in plants and involved in multiple biological processes. However, the role of the WRKY family had not been reported in Eucommia ulmoides. In this study, 45 WRKY genes (EuWRKY1-45) with conserved WRKY domain were identified in E. ulmoides and classified into three groups. The group II was further divided into five subgroups based on phylogenetic analysis, and each clade was well supported by the conserved motifs. All the genes were located on 34 different scaffolds respectively. A number of development-, light-, hormone-, and stress-related elements were randomly distributed in the promoter sequences of EuWRKYs. Expression profiles indicated that EuWRKY genes were involved in leaf development, and majority of EuWRKYs genes were highly expressed in leaf buds. Co-expression analysis of WRKYs suggested an intricate interplay of growth-related responses. EuWRKY4 was involved in a complex proteins interaction network. Collectively, our results provide extensive insights into the WRKY gene family, thereby contributing to the screening of additional candidate genes in E. ulmoides.Mealybugs are aggressive pests with world-wide distribution and are suitable for the study of different phenomena like genomic imprinting and epigenetics. Genomic approaches facilitate these studies in absence of robust genetics in this system. We sequenced, de novo assembled, annotated Maconellicoccus hirsutus genome. We carried out comparative genomics it with four mealybug and eight other insect species, to identify expanded, specific and contracted gene classes that relate to pesticide and desiccation resistance. We identified horizontally transferred genes adding to the mutualism between the mealybug and its endosymbionts. Male and female transcriptome analysis indicates differential expression of metabolic pathway genes correlating with their physiology and the genes for sexual dimorphism. The significantly lower expression of endosymbiont genes in males relates to the depletion of endosymbionts in males during development.MicroRNAs (miRNAs) are short (21-23 nt) regulatory RNA molecules present in plants and animals which are known for regulating the mRNA target gene expression either by cleavage or translational repression. With the advancements in miRNAs research in plants towards their biogenesis and applications has directed the recent discovery of pri-miRNAs encoding functional peptides or microRNA peptides (miPEPs). These miPEPs are encoded by 5′ of pri-miRs containing short ORFs (miORFs). miPEPs are known to enhance the activity of their associated miRNAs by increasing their accumulation and hence downregulating the target genes. Since miPEPs are very specific for each miRNA, they are considered as novel and effective tools for improving traits of interest for plant growth promotion and plant-microbe interaction. Entire peptidome research is the need of the hour. This review thus summarizes recent advancements in miPEP research and its applications as a technology with important agronomical implications with miRNAs augmentation.
