Molecular cytogenetics in the study of repetitive sequences helping to understand the evolution of heterochromatin in Melipona (Hymenoptera, Meliponini) Genetica (IF 1.186) Pub Date : 2021-01-15 Jaqueline Amorim Pereira, Natália Martins Travenzoli, Monique Póvoa de Oliveira, Hugo de Azevedo Werneck, Tânia Maria Fernandes Salomão, Denilce Meneses Lopes
The eukaryote genome is enriched by different types of repetitive DNA sequences and is most abundant in heterochromatin regions. Historically, no function has been assigned to these sequences, which makes them the target of studies that have demonstrated their structural and functional importance in the genome.

Epigenetic memory and priming in plants. Genetica (IF 1.186) Pub Date : 2020-04-30 Neslihan Turgut-Kara,Burcu Arikan,Haluk Celik
In nature, plants are regularly exposed to biotic and abiotic stress conditions. These conditions create potential risks for survival. Plants have evolved in order to compete with these stress conditions through physiological adjustments that are based on epigenetic background. Thus, the ecological signals create different levels of stress memory. Recent studies have shown that this stress-induced

Apoptosis inhibition mitigates aging effects in Drosophila melanogaster. Genetica (IF 1.186) Pub Date : 2020-03-27 Hiroaki Kidera,Toshimitsu Hatabu,Kazuo H Takahashi
Aging is a natural biological process that results in progressive loss of cell, tissue, and organ function. One of the causing factors of the aging process is the decrease in muscle mass, which has not been fully verified in Drosophila. Apoptotic cell death may result in aberrant cell loss and can eventually diminish tissue function and muscle atrophy. If so, inhibition of apoptosis may prolong longevity

Trifolium alexandrinum (Egyptian clover) is a widely cultivated winter annual fodder. Present work deals with inheritance of the seed coat colour in segregating progenies of the interspecific cross between T. alexandrinum and T. apertum. Although, both the parent species possessed yellow seed coat, the F1 seeds were black coloured in the reciprocal cross (T. apertum × T. alexandrinum). Seeds borne

TaEPFL1, an EPIDERMAL PATTERNING FACTOR-LIKE (EPFL) secreted peptide gene, is required for stamen development in wheat. Genetica (IF 1.186) Pub Date : 2019-03-27 Qingxu Sun,Jipeng Qu,Yan Yu,Zaijun Yang,Shuhong Wei,Yilei Wu,Jun Yang,Zhengsong Peng
Members of the EPIDERMAL PATTERNING FACTOR-LIKE (EPFL) family play diverse roles in plant growth and development, including the guidance of inflorescence architecture and pedicel length. In this work, we identified and characterized the EFPL gene TaEPFL1 from the wheat pistillody mutant HTS-1. Sequence alignment and phylogenetic analysis indicated that TaEPFL1 belongs to the EPFL1 gene. Quantitative

Genome-wide identification and expression analysis of the AAAP family in Medicago truncatula. Genetica (IF 1.186) Pub Date : 2019-03-25 Yue Qu,Lei Ling,Dan Wang,Tong Zhang,Changhong Guo
The amino acid/auxin permease (AAAP) gene family plays an important role in the long-distance amino acid transport pathway and takes part in various stages of plant growth and development. However, little is known about the AAAP gene family in Medicago truncatula. Here, we identified 86 putative MtAAAP family members using genome sequence information. Based on phylogenetic analysis, these MtAAAP genes

Comparative mitogenomic and phylogenetic analysis of Apalone spinifera and Apalone ferox (Testudines: Trionychidae). Genetica (IF 1.186) Pub Date : 2019-03-20 Peng Yu,Xiaoli Yang,Weishang Zhou,Wentao Yang,Li Zhou,Xuan Liu,Quan Wan,Jun Zhang
The soft-shell turtles Apalone spinifera (AS) and Apalone ferox (AF) are two important economic species. AF is found in the Yellow River of China, and is a confirmed member of the Trionychidae family. However, the classification of AS was in dispute. Mitochondrial genomes (mitogenomes) have been widely used for species identification, as well as population and phylogenetic analysis. In order to understand

Genetic structure of Kho population from north-western Pakistan based on mtDNA control region sequences. Genetica (IF 1.186) Pub Date : 2019-03-20 Shahid Aziz,Mehwish Nawaz,Sahib Gul Afridi,Asifullah Khan
The Kho population speaking Khowar language reside since long ago in Chitral District of North-western Pakistan. So far, no report is available about their genetic structure and relationship with surrounding population groups. We partially sequenced the mitochondrial DNA control region from 16 unrelated Kho male and female individuals of different ages. The D-Loop region sequences of Kho were aligned

Genetic diversity and demography of the critically endangered Roberts' false brook salamander (Pseudoeurycea robertsi) in Central Mexico. Genetica (IF 1.186) Pub Date : 2019-03-18 Armando Sunny,Luis Duarte-deJesus,Arlene Aguilera-Hernández,Fabiola Ramírez-Corona,Marco Suárez-Atilano,Ruth Percino-Daniel,Javier Manjarrez,Octavio Monroy-Vilchis,Andrea González-Fernández
Land use changes are threatening the maintenance of biodiversity. Genetic diversity is one of the main indicators of biological diversity and is highly important as it shapes the capability of populations to respond to environmental changes. We studied eleven populations of Pseudoeurycea robertsi, a micro-endemic and critically endangered species from the Nevado de Toluca Volcano, a mountain that is

Adaptive evolution of the ACSL gene family in Carnivora. Genetica (IF 1.186) Pub Date : 2019-03-15 Chao Zhao,Guangshuai Liu,Shuai Shang,Qinguo Wei,Lei Zhang,Tian Xia,Xiufeng Yang,Guolei Sun,Honghai Zhang
Carnivores exhibit various fat contents and energy reserves to adapt to their environments. However, the molecular mechanisms underlying lipid metabolic differences among carnivores have not been well explored. Long-chain acyl-CoA synthetases (ACSLs) catalyze the initial step in lipid metabolism by activating fatty acids (FAs), and they drive acyl-CoAs toward anabolic lipid synthesis or catabolic β-oxidation

Characterization and phylogeny of bitter taste receptor genes (Tas2r) in Squamata. Genetica (IF 1.186) Pub Date : 2019-03-07 Huaming Zhong,Shuai Shang,Huanxin Zhang,Jun Chen,Xiaoyang Wu,Honghai Zhang
The perception of bitter taste is linked to the detection of toxins. Therefore, it facilitates avoiding the consumption of potential toxins in the diet. At the molecular level, bitter taste is mediated by taste 2 receptors (Tas2rs). Studies on Tas2r have made major advances in recent years. However, little is known about Tas2rs in Squamata, the second largest order of extant vertebrates. To explore

Genetic analysis of the grapevine genotypes of the Russian Vitis ampelographic collection using iPBS markers. Genetica (IF 1.186) Pub Date : 2019-02-21 Alexander Milovanov,Andrey Zvyagin,Asset Daniyarov,Ruslan Kalendar,Leonid Troshin
Cultivated grapevine (Vitis vinifera L. ssp. sativa D.C.) is one of the oldest agricultural crops, each variety comprising an array of clones obtained by vegetative propagation from a selected vine grown from a single seedling. Most clones within a variety are identical, but some show a different form of accession, giving rise to new divergent phenotypes. Understanding the associations among the genotypes

AFLP markers show low levels of clonal propagation and high genotypic diversity in the rare, southernmost populations of Linnaea borealis L. (Caprifoliaceae) in the Western Alps. Genetica (IF 1.186) Pub Date : 2019-02-16 Myriam Gaudeul,Thierry Delahaye,Serge Muller
In plants, clonal propagation is a common reproductive strategy in parallel to sexual reproduction. It has both advantages and drawbacks, and the potential complete loss of sexual reproduction causes serious conservation concerns, especially because population maintenance then only relies on adult survival and low genetic diversity leads to decreased adaptive potential. We investigated the rare, southernmost
