Background: Newborn screening (NBS) has been implemented for neonatal inborn disorders using various technology platforms, but false-positive and false-negative results are still common. In addition, target diseases of NBS are limited by suitable biomarkers. Here we sought to assess the feasibility of further improving the screening using next-generation sequencing technology.

Centromeres are indispensable functional units of chromosomes. The evolutionary mechanisms underlying the rapid evolution of centromeric repeats, especially those following polyploidy, remain unknown. In this study, we isolated centromeric sequences of Brassica nigra, a model diploid progenitor (B genome) of the allopolyploid species B.

Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability and the leading monogenic cause of autism spectrum disorder. It has previously been demonstrated that prenatal genetic diagnosis is efficient for the diagnosis of FXS. The present study investigated the diagnostic effects of nested polymerase chain reaction (PCR) for fragile X mental retardation 1 (FMR1) and expanded CGG repeats.

Whole-genome shotgun reads were analyzed to determine the repeat sequence composition in the genome of black mustard, Brassica nigra (L.) Koch. The analysis showed that satellite DNA sequences are very abundant in the black mustard genome.

Objectives: The purpose of this study was to investigate the changes in the morphologic characteristics and performance of the right atrium (RA) that occur secondary to structural remodeling of the right ventricle (RV) in patients with pulmonary hypertension by real-time 3-dimensional echocardiography (3DE).

Methods: Comprehensive 2-dimensional echocardiography and real-time 3DE were performed in 112 patients and 30 healthy control participants. Patients with pulmonary hypertension were divided into 3 subgroups: 1, normal RV dimension (n = 34); 2, RV enlargement and preserved systolic function (n = 36); and 3, RV enlargement and systolic dysfunction (n = 42).

Parthenocarpic fruit is a very attractive trait for consumers and especially in eggplants where seeds can lead to browning of the flesh and bitterness. However, the molecular mechanisms underlying parthenocarpy in eggplant still remain unknown. Some auxin response factors have been previously shown in model species, such as Arabidopsis and tomato, to play an important role in such a process.

Article Synopsis
  • Acrylamide forms in carbohydrate-rich foods, especially french fries and potato chips, when cooked at high temperatures, raising health concerns as a potential carcinogen.
  • Researchers developed potato lines with reduced acrylamide precursors (asparagine, glucose, and fructose) by silencing specific genes, leading to a significant decrease in acrylamide levels during frying.
  • The findings suggest that improving potato cultivars to have lower reducing sugars can effectively reduce acrylamide formation in fried potato products.

Background: Coix, Sorghum and Zea are closely related plant genera in the subtribe Maydeae. Coix comprises 9-11 species with different ploidy levels (2n = 10, 20, 30, and 40). The exclusively cultivated C.

Meiosis is the crucial step for sexual reproduction, while the pairing, synapsis and recombination are the key events in this process and have become the hotspots in meiosis studies. In recent years, with the development of the molecular biology and cell biology, associated with the mutant screened from mutant libraries, much advances were achieved in pairing, synapsis and recombination of meiosis in plant. In this review, we have gave an overview of the genes identification in this field and further studies of its molecular mechanism in plant.

CENH3 is a centromere-specific histone H3 variant and has been used as a marker to identify active centromeres and DNA sequences associated with functional centromere/kinetochore complexes. In this study, up to four distinct CENH3 (BrCENH3) cDNAs were identified in individuals of each of three diploid species of Brassica. Comparison of the BrCENH3 cDNAs implied three related gene families: BrCENH3-A in Brassica rapa (AA), BrCENH3-B in B.
