B-box transcription factors (TFs) in plants are essential for circadian rhythm regulation, abiotic stress responses, hormonal signaling pathways, secondary metabolism, photomorphogenesis, and anthocyanin formation. Here, by blasting the gene sequence, we identified a total of 18 genes from five distinct species (, , , , and ). The gene is most closely linked to the gene based on phylogeny and protein sequence similarities.

Phenylalanine ammonia-lyase (PAL) acts as the rate-limiting enzyme for anthocyanin biosynthesis through the phenylpropanoid pathway, a crucial component of plant secondary metabolism. The gene family plays a crucial role in plants' defense and stress responses, but its in silico identification and expression analyses in under different abiotic stresses remain unexplored. In this study, nine , seven , four , and seventeen genes were obtained from the genomes of , , , and , respectively.

is a vital seed and soil-borne phytopathogen responsible for substantial crop yield losses. Although various methods exist for managing soil-borne pathogens, such as agronomic practices, chemical treatments, and varietal tolerance, biological control utilizing plant growth-promoting rhizobacteria (PGPR) or their secondary metabolites presents promising avenues. In this study, a screening of 150 isolates from the rhizosphere of L.

Background: The vivid red, purple, and blue hues that are observed in a variety of plant fruits, flowers, and leaves are produced by anthocyanins, which are naturally occurring pigments produced by a series of biochemical processes occurring inside the plant cells. The purple-stalked Chinese kale, a popular vegetable that contains anthocyanins, has many health benefits but needs to be investigated further to identify the genes involved in the anthocyanin biosynthesis and translocation in this vegetable.

Results: In this study, the purple- and green-stalked Chinese kale were examined using integrative transcriptome and metabolome analyses.

Taro is a plant in the family, and its leafstalk possesses significant botanical and culinary value owing to its noteworthy medicinal and nutritional attributes. Leafstalk colour is an essential attribute that significantly influences its desirability and appeal to both breeders and consumers. However, limited information is available about the underlying mechanism responsible for the taro plant's colouration.

Article Synopsis
  • Flowering Chinese cabbage is a popular vegetable in southern China, and its anthocyanin content is significant for its health benefits and color.
  • Researchers conducted a transcriptome analysis on two types of flowering Chinese cabbage with different stem colors, revealing 6811 differentially expressed genes (DEGs), including 295 related to transcription factors.
  • The study identified key biosynthesis pathways enriched in the purple variety and pinpointed 25 DEGs crucial for anthocyanin production, proposing a candidate gene that regulates this process, thus enhancing understanding of the molecular mechanisms responsible for the purple coloration in these plants.

and are important medicinal plants with unique chemical compositions that are widely used in traditional Chinese medicine. To compare the nutritional and medicinal profiles of these two species, we analyzed the flavonoid, dietary fiber, total starch, and crude protein contents of one and three varieties using ultra-performance liquid chromatography-tandem mass spectrometry, enzyme weight, acid hydrolysis, and Kjeldahl methods. Furthermore, we used principal component analysis and hierarchical clustering heatmap analysis to separate the data obtained from the and samples.
