... Bananas (Musa spp.) are an important source of pro-vitamin A, derived from carotenoids. Some cultivated bananas originated from intra-specific hybridization resulting in genotypes which are diploid (AA) and triploid (AAA) genomes that are the most important bananas for desserts. The accumulation of carotenoids and transcripts of genes related to carotenoid biosynthesis during fruit development and ...
... Fish cell lines are important tools in many biological studies. Here, we established a new Japanese flounder brain (JFB) cell line from the brain tissue of the Japanese flounder (Paralichthys olivaceus), which was successfully sub-cultured for over 120 passages, and consisted predominantly of fibroblast-like cells. Sequencing of the actin gene confirmed that JFB cells were derived from the Japanes ...
... The doubling of the plant genome causes obvious morphological and physiological changes, and DNA 5-methylcytosine (5mCs) modification is a key epigenetic component that helps neopolyploids overcome challenges and acquire advantages. In the study of autotetraploid grape, we found that leaf thickness, photosynthetic and antioxidant capacity increased and anthocyanin coloring decreased in autotetrapl ...
... Field trials to evaluate the performance of new varieties are an essential component of potato breeding. Besides the genetic differences, environmental factors can lead to variation in a trial. In variety trials, the observed differences amongst varieties should reflect genetic differences, without a large impact of the random or systematic variation in the field. One way to reduce within-field va ...

Abstract:
... The technology of hybrid breeding in diploid potatoes creates opportunities to design novel and improved cultivation systems based on hybrid true potato seeds. A promising cultivation pathway to produce seed or ware tubers is by transplanting greenhouse-raised seedlings into the field. This study explored the effects of transplanting date and seedling age on tuber yield, using greenhouse-raised se ...

Abstract:
... The rapid and efficient selection of qualified haploid maize kernels plays an important role in maize breeding. However, considering the rarity of haploid maize kernels, usually only a limited data set can be obtained, which easily leads to poor generalization ability and instability of established classifiers. In this work, hyperspectral imaging (HSI) combined with generative adversarial network ...

Abstract:
... As an ancient allotetraploid species, goldfish (Carassius auratus) have two sets of subgenomes. In this study, immunoglobulin heavy-chain (IGH) genes were cloned from the red crucian carp (Carassius auratus red var.), and the corresponding loci were identified in the gynogenetic diploid red crucian carp (GRCC) genome as well as the genomes of three other goldfish strains (Wakin, G-12, and CaTCV-1) ...
diploidy, etc ; allopolyploidy; aneuploidy; coevolution; epigenetics; fractionation; meiosis; mutation; Show all 8 Subjects
Abstract:
... Newly formed polyploids often show extensive meiotic defects, resulting in aneuploid gametes, and thus reduced fertility. However, while many neopolyploids are meiotically unstable, polyploid lineages that survive in nature are generally stable and fertile; thus, those lineages that survive are those that are able to overcome these challenges. Several genes that promote polyploid stabilization are ...

Abstract:
... The TIFY gene family plays important roles in various plant biological processes and responses to stress and hormones. The chromosome-level genome of the Brassiceae species has been released, but knowledge concerning the TIFY family is lacking in the Brassiceae species. The current study performed a bioinformatics analysis on the TIFY family comparing three diploid (B. rapa, B. nigra, and B. olera ...

Abstract:
... Induced pluripotent stem cells (iPSCs) hold great potential for regenerative medicine. By reprogramming a patient′s own cells, immunological rejection can be avoided during transplantation. For expansion and gene editing, iPSCs are grown in artificial culture for extended times. Culture affords potential danger for the accumulation of genetic aberrations. To study these, two induced pluripotent st ...

Abstract:
... The widespread Senecio squalidus L. (Compositae: Senecioneae: Senecioninae), a diploid hybrid species with strong self‐incompatibility, that originated in the British Isles within the last 300 years, is described and illustrated. The origins of this species are briefly outlined. The history of the spread of this plant in the British Isles, and the presence of several natural hybrids is commented o ...

Abstract:
... In angiosperms, after the egg fuses with the sperm, many structural, physiological, and molecular biological changes occur in the fertilized egg. All of these changes facilitate the conversion of the haploid egg into the diploid zygote, a process known as the maternal-to-zygotic transition (MZT). In the egg, fertilized egg, and zygote, changes occur at each stage under the control of exact spatio- ...

Abstract:
... The cultivation of Miscanthus has attracted growing interest despite its yield instability. Therefore, understanding what causes such instability is of primary interest for breeding. Our objectives were to estimate the genetic parameters—genetic variance and genetic heritability—and genetic correlations for flowering time-related traits in a biparental Miscanthus sinensis diploid population, and d ...

Abstract:
... The paper analyzes the latest data on 5038 species of herbs presented by the Kew Botanic Gardens (Great Britain). The following genomic parameters were investigated: the dependence of annual plant ratio as the percentage of total number of annual and perennial species on the holoploid DNA content (C-value), ploidy and number of chromosomes. Previously, it was shown that C-value in annuals is lower ...

Abstract:
... The family Mytilidae generally shows a genus-specific diploid number (2n) of chromosomes; however, one species from each genus, with the exception of Mytilus, is known to have a variable diploid number. Perna viridis is a cytogenetically significant species because it has a diploid chromosome (2n) number of 30, whereas the rest of species of genera Perna and Mytilus have a diploid number of 28. In ...

Abstract:
... BACKGROUND: Simple translocations and complex rearrangements are formed through illegitimate ligations of double-strand breaks of fusion partners and lead to generation of oncogenic fusion genes that affect cellular function. The contact first hypothesis states that fusion partners tend to colocalize prior to fusion in normal cells. Here we test this hypothesis at the single-cell level and explore ...

Abstract:
... We introduce CellPhy, a maximum likelihood framework for inferring phylogenetic trees from somatic single-cell single-nucleotide variants. CellPhy leverages a finite-site Markov genotype model with 16 diploid states and considers amplification error and allelic dropout. We implement CellPhy into RAxML-NG, a widely used phylogenetic inference package that provides statistical confidence measurement ...

Abstract:
... Polyploidy is the main mechanism for chromosome number variation in Cynodon. Taxonomic boundaries are difficult to define and, although phylogenetic studies indicate that some species are closely related, the degree of genomic similarity remains unknown. Furthermore, the Cynodon species classification as auto or allopolyploids is still controversial. Thus, this study aimed to investigate the genom ...

Abstract:
... Ipomoea trifida, the closest relative of sweetpotato, does not generally form storage roots, but some lines develop thick roots similar to the storage roots of the sweetpotato. Revealing the molecular mechanism of thick root development in I. trifida would help us understand the evolution of storage roots in the sweetpotato. In this study, we conducted a mapping method for quantitative trait loci ...
