Plant-specific WRKY transcription factors (TFs) have been implicated to function as regulators of leaf senescence, but their association with postharvest leaf senescence of economically important leafy vegetables, is poorly understood. In this work, the characterization of a Group IIe WRKY TF, BrWRKY65, from Chinese flowering cabbage (Brassica rapa var. parachinensis) is reported. The expressio...

The aim of this research was to improve our understanding of how ploidy level influences phenotype and gene expression in Chinese cabbage (Brassica rapa L. ssp. pekinensis). Haploid plants (2n = 10) was induced by 0.2% colchicine to produce diploid (2n = 20) and tetraploid plants (2n = 40). The aneuploid (2n = 24) was also obtained by hybridization between diploid plants as the female and tetra...

The complete sequence of the mitochondrial genome was determined for two cultivars of Brassica rapa. After determining the sequence of a Chinese cabbage variety, 'Oushou hakusai', the sequence of a mizuna variety, 'Chusei shiroguki sensuji kyomizuna', was mapped against the sequence of Chinese cabbage. The precise sequences where the two varieties demonstrated variation were ascertained by dire...

Alterations in leaf adaxial-abaxial (ad-ab) polarity are one of the main factors that influence leaf curvature. In Chinese cabbage, leaf incurvature is an essential prerequisite to the formation of a leafy head. Identifying ad-ab patterning genes and investigating their genetic variation may facilitate elucidation of the mechanisms underlying leaf incurvature during head formation. Comparative ...

Chinese cabbage is a key vegetable crop in northwest China. It of great significance to study the evapotranspiration (ET) and coefficient (Kc) for agricultural water-saving management this area. Eddy covariance (EC) was used measure ET Kc China from 1 May 16 October 2020, order analyze characteristics these variables under plastic mulch. The results showed that average first higher middle late ...

The structure and chemical properties of strontium calcium are similar. To study the interplay between in plants, different concentrations SrCl 2 (0, 1, 4, 10 mmol·L −1 ) were added to Hoagland nutrient solution with 4 Ca 2+ (normal level or 0.4 (low-level ), which used cultivate Chinese cabbage seedlings. Under low-level condition, not only did promote growth but showed more severe toxicity co...

Plant drought tolerance depends on adaptations of the photosynthetic apparatus to changing environments triggered by water deficit. The seedlings three Brassica crops differing in sensitivity, oleracea L. var. capitata—white cabbage, acephala—kale, and rapa pekinensis—Chinese were exposed withholding water. Detailed insight into machinery was carried out when seedling reached a relative content...

YABBY gene family plays an important role in the polarity development of lateral organs. We isolated the BraYAB1-702 gene, a member of the YABBY gene family, from young leaves of Chinese cabbage line 06J45. The full-length gene has a 937 bp CDNA sequence and contains an open reading frame (ORF) of 702 bp. The subcellular localization analysis showed that the expression product of the gene was l...

Demographic modelling is often used with population genomic data to infer the relationships and ages among populations. However, relatively few analyses are able to validate these inferences with independent data. Here, we leverage written records that describe distinct Brassica rapa crops to corroborate demographic models of domestication. Brassica rapa crops are renowned for their outstanding...

Anthocyanins, the most prevalent flavonoids in red/purple fruits and vegetables, are known to improve immune responses and reduce chronic disease risks. In this study, the anti-inflammatory activities of an anthocyanin-rich extract from red Chinese cabbage (ArCC) were shown based on its inhibitory effects in cultured endothelial cells and hyperlipidemic apolipoprotein E-deficient mice. ArCC tre...
