Comparative Metabolome and Transcriptome Analysis of Rapeseed ( L.) Cotyledons in Response to Cold Stress.

Cold stress affects the seed germination and early growth of winter rapeseed, leading to yield losses. We employed transmission electron microscopy, physiological analyses, metabolome profiling, and transcriptome sequencing to understand the effect of cold stress (0 °C, LW) on the cotyledons of cold-tolerant (GX74) and -sensitive (XY15) rapeseeds. The mesophyll cells in cold-treated XY15 were severely damaged compared to slightly damaged cells in GX74.

Genome-wide identification and evolutionary analysis of the NRAMP gene family in the AC genomes of Brassica species.

Background: Brassica napus, a hybrid resulting from the crossing of Brassica rapa and Brassica oleracea, is one of the most important oil crops. Despite its significance, B. napus productivity faces substantial challenges due to heavy metal stress, especially in response to cadmium (Cd), which poses a significant threat among heavy metals.

Expression in and cellular localization reveal involvement of in cadmium uptake.

Although has demonstrated potential as a hyperaccumulator crop, it was not entirely clear how cadmium (Cd) accumulates in plants. Here, we found that BjNRAMP1 (Natural Resistance-Associated Macrophage Protein 1) plays a crucial role in the accumulation of Cd and manganese (Mn) through its expression in yeast and . The high concentration of Cd exposure could induce the expression of .

A gap-free reference genome reveals structural variations associated with flowering time in rapeseed ().

Allopolyploid oilseed rape () is an important oil crop and vegetable. However, the latest version of its reference genome, with collapsed duplications, gaps, and other issues, prevents comprehensive genomic analysis. Herein, we report a gap-free assembly of the rapeseed cv.

BnaC01.BIN2, a GSK3-like kinase, modulates plant height and yield potential in Brassica napus.

Using map-based cloning and transgenic transformation, we revealed that glycogen kinase synthase 3-like kinase, BnaC01.BIN2, modulates plant height and yield in rapeseed. The modification of plant height is one of the most important goals in rapeseed breeding.

Clinical Manifestations, Imaging Features, and Pathogenic/Prognostic Risk Factors for Temporomandibular Disorders (TMD): A Case-Control Study Based on Psychogenic Factors of Patients.

Objective: To survey the clinical manifestations and imaging features of temporomandibular disorders (TMD) and analyze the risk factors for pathogenesis/prognosis through a case-control study based on psychogenic factors of patients.

Methods: According to the inclusion criteria, 200 adult patients were randomly enrolled from the maxillofacial department of our hospital from January 2020 to May 2021, including 100 patients with TMD as the study group and 100 healthy patients as the control group. The study group can be assigned into four subgroups according to their clinical manifestations: (1) articular area or/and masticatory muscle pain group, (2) mandibular movement abnormality group, (3) joint murmur group, and (4) two or more symptom groups.

Fine mapping of qDB.A03, a QTL for rapeseed branching, and identification of the candidate gene.

Increasing the yield of rapeseed is required to meet the rapidly expanding demand for both edible vegetable oil and biofuel. Branching, an important determinant of yield potential in rapeseed, is controlled by a series of quantitative trait loci (QTLs). To explore the genetic mechanism regulating the natural variation of branching, a BCF population derived from a cross between dense branching 2 (dense branching line) and L72 (normal branching line) was used to map QTL conferring branching in rapeseed.
