Tocopherols are a class of four natural compounds that can provide nutrition and function as antioxidant in both plants and animals. Maize kernels have low α-tocopherol content, the compound with the highest vitamin E activity, thus, raising the risk of vitamin E deficiency in human populations relying on maize as their primary vitamin E source. In this study, two insertion/deletions (InDels) w...
To increase our understanding of the genes involved in flowering in citrus, we performed genome resequencing of an early flowering trifoliate orange mutant (Poncirus trifoliata L. Raf.) and its wild type. At the genome level, 3,932,628 single nucleotide polymorphisms (SNPs), 1,293,383 insertion/deletion polymorphisms (InDels), and 52,135 structural variations were identified between the mutant ...
We recently suggested that sites of length polymorphisms in protein families (indels) might serve as useful guides for locating protein:protein interaction sites. This report describes additional site-specific mutagenesis and synthetic peptide inhibition studies aimed at testing this idea for the paralogous complement C3, C4, and C5 proteins. A series of C5 mutants was constructed by altering t...
با وجود ارزش بالای تشخیصی اندازه گیری زمان تخلیه روده بزرگ (CTT) در ارزیابی بیماران مبتلا به یبوست، متاسفانه انجام این روش به دلیل گرانی مواد خارجی و تا حدی عدم شناخت آن توسط پزشکان با محدودیت روبرو است. بنابراین ما بر آن شدیم تا با مقایسه مارکرهای داخلی و خارجی بتوانیم مشکل تهیه و هزینه آن را رفع کنیم. بدین منظور 20 بیمار مبتلا به یبوست مزمن که در بررسی های بالینی و آزمایشگاهی هیچگونه شواهدی د...
Insertions and deletions (indels) are important types of structural variations. Obtaining accurate genotypes of indels may facilitate further genetic study. There are a few existing methods for calling indel genotypes from sequence reads. However, none of these tools can accurately call indel genotypes for indels of all lengths, especially for low coverage sequence data. In this paper, we prese...
Improvement of variant calling in next-generation sequence data requires a comprehensive, genomewide catalogue of high-confidence variants called in a set of genomes for use as a benchmark. We generated deep, whole-genome sequence data of seventeen individuals in a three-generation pedigree and called variants in each genome using a range of currently available algorithms. We used haplotype tra...
Eggshell damages lead to economic losses in the egg production industry and are a threat to human health. We examined 49-wk-old Rhode Island White hens (Gallus gallus) that laid eggs having shells with significantly different strengths and thicknesses. We used HiSeq 2000 (Illumina) sequencing to characterize the chicken transcriptome and whole genome to identify the key genes and genetic mutati...
Comparative genomics of closely related bacterial strains can clarify mutational processes and selective forces that impact genetic variation. Among primary bacterial endosymbionts of insects, such analyses have revealed ongoing genome reduction, raising questions about the ultimate evolutionary fate of these partnerships. Here, we explored genomic variation within Blochmannia vafer, an obligat...
BACKGROUND Schizophrenia (SCZ) is a severe, debilitating, and complex psychiatric disorder with multiple causative factors. An increasing number of studies have determined that rare variations play an important role in its etiology. A somatic mutation is a rare form of genetic variation that occurs at an early stage of embryonic development and is thought to contribute substantially to the deve...
Proteins evolve through two primary mechanisms: substitution, where mutations alter a protein's amino-acid sequence, and insertions and deletions (indels), where amino acids are either added to or removed from the sequence. Protein structure has been shown to influence the rate at which substitutions accumulate across sites in proteins, but whether structure similarly constrains the occurrence ...
