Innate immunity; Macaca thibetana; Phylogenetic analysis; TLR4 gene; Toll-like receptor

In this study, the complete coding region sequence of an innate immune-related TLR4 gene was obtained from the Tibetan macaque (Macaca thibetana) genome via PCR and direct sequencing. The sequence had a total length of 2481 bp, contained 3 complete exons, and encoded 826 amino acids (AAs); its isoelectric point was 5.703, and the molecular weight was 94.72 kDa. The high ... more

Ganoderma identification and classification; Ganoderma spp; Mitochondrial small subunit rDNA; Phylogenetic analysis

Ganoderma mushroom is one of the most prescribed traditional medicines and has been used for centuries, particularly in China, Japan, Korea, and other Asian countries. In this study, different strains of Ganoderma spp and the genetic relationships of the closely related strains were identified and investigated based on the V4-V6 region of mitochondrial small subunit ... more

Genetic gains; Intrapopulation selection; Selection indexes; Zea mays

We estimated genetic gains for popcorn varieties using selection indexes in a fourth cycle of intrapopulation recurrent selection developed in the campus of the Universidade Estadual do Norte Fluminense. Two hundred full-sib families were obtained from the popcorn population UNB-2U of the third recurrent selection cycle. The progenies were evaluated in a randomized block design with two ... more

Expression; FKBPs; Gene duplication; Maize

The receptors for the immunosuppression drugs FK506 and rapamycin are called FKBPs (FK506-binding proteins). FKBPs comprise a large family; they are found in many species, including bacteria, fungi, animals, and plants. As a class of peptidyl-prolyl cis-trans isomerase enzymes, the FKBP genes have been the focus of recent studies on plant stress tolerance and immunology. We ... more

DRB; Gene duplication; MHC; Sequence variation; Spotted seal (Phoca largha)

The major histocompatibility complex (MHC) is one of the most important genetic systems associated with resistance to infectious diseases in vertebrates. The spotted seal (Phoca largha) is one of the most endangered species in China. In this study, we present the first step in the molecular characterization of a DRB-like locus in the spotted seal by analyzing the nucleotide ... more

Gene duplication; Genetic polymorphism; Yak; κ-casein

The objective of this study was to compare 12 bp-duplication polymorphisms in exon 4 of the κ-casein gene among 3 breeds/populations of yak (Bos grunniens). Genomic DNA was extracted from yak blood or muscle samples (N = 211) and a partial sequence of exon 4 of κ-casein gene was amplified by polymerase chain reaction. A polyacrylamide gel electrophoresis assay of the products (169 bp ... more

diallel analysis; Genetic divergence; Heterosis; Molecular markers; Popcorn; Zea mays

Diallel analysis was used to obtain information on com­bining ability, heterosis, estimates of genetic distances by random amplified polymorphic DNA (RAPD) and on their correlations with heterosis, for the popcorn varieties RS 20, UNB2, CMS 43, CMS 42, Zélia, UEM J1, UEM M2, Beija-Flor, and Viçosa, which were crossed to obtain all possible combinations, without reciprocals. The genitors ... more

Drought tolerance; Genetic variation; Linkage maps; Molecular markers; Quantitative trait loci; Zea mays

Drought tolerance is one of the most important but complex traits of crops. We looked for quantitative trait loci (QTLs) that affect drought tolerance in maize. Two maize inbreds and their advanced lines were evaluated for drought-related traits. A genetic linkage map developed using RFLP markers was used to identify QTLs associated with drought-related traits. Twenty-two QTLs were ... more

Genetic variation; Maize; Quantitative traits; RAPD markers; Zea mays

We compared DNA-based genetic diversity estimates with conventional estimates by investigating agronomically important traits in maize grown in the northwestern region of Pakistan. RAPD markers were used to characterize 10 commonly cultivated maize genotypes. The same material was tested for phenotypic variation of quantitative traits using replicated field trials. The genetic distances ... more
