AI Article Synopsis

  • Brassica vegetables are rich in bioactive compounds that contribute to human health, particularly polyphenols.
  • A detailed analysis using advanced mass spectrometry techniques identified 164 different polyphenols from five Brassica microgreen species, including various anthocyanins and flavonoids.
  • The study concludes that these microgreens are valuable sources of food polyphenols, supporting their potential health benefits.

Article Abstract

Brassica vegetables are known to contain relatively high concentrations of bioactive compounds associated with human health. A comprehensive profiling of polyphenols from five Brassica species microgreens was conducted using ultrahigh-performance liquid chromatography photodiode array high-resolution multistage mass spectrometry (UHPLC-PDA-ESI/HRMS(n)). A total of 164 polyphenols including 30 anthocyanins, 105 flavonol glycosides, and 29 hydroxycinnamic acid and hydroxybenzoic acid derivatives were putatively identified.The putative identifications were based on UHPLC-HRMS(n) analysis using retention times, elution orders, UV-vis and high-resolution mass spectra, and an in-house polyphenol database as well as literature comparisons. This study showed that these five Brassica species microgreens could be considered as good sources of food polyphenols.

Crop plants are severely affected by heavy metals (HMs), leading to food scarcity and economical loss. Lead (Pb) is outsourced by use of lead-based fertilizers, batteries, mining, smelting and metal processing. It significantly reduces growth, development and yield of crops cultivated on contaminated sites.

Understanding the early interactions between plants and endophytes will contribute to a more systematic approach to enhancing endophyte-mediated effects on plant growth and environmental stress resistance. This study examined very early growth and ascorbate metabolism after seed treatment of with three different endophytes. The three endophytes used were pb1(Bapb1), (Ml) and SLB4 (SLB4).

Tolerance to insect herbivory increases with progressing plant development.

Plants can sustain various degrees of damage or compensate for tissue loss by regrowth without significant fitness costs. This tolerance to insect herbivory depends on the plant's developmental stage during which the damage is inflicted and on how much tissue is removed. Plant fitness correlates, that is, biomass and germination of seeds, were determined at different ontogenetic stages, vegetative, budding, or flowering stages of three annual brassicaceous species exposed to feeding by Pieris brassicae caterpillars at different intensities.

Heat shock transcription factors (Hsfs) play important roles in plant developmental regulations and various abiotic stress responses. However, their evolutionary mechanism of freezing tolerance remains poorly understood. In our previous transcriptomics study based on DNA methylation sequencing, the BnaHsfA2 was found to be significantly accumulated in winter rapeseed (Brassica rapa L.

Nitrogen-containing heterocycles have attracted attention for the development of chemicals because of their many types, high physiological activities, and ease of synthesis. Aphids are severe pests found worldwide that cause serious losses in crop yield and quality every year. In this study, a series of novel dienolone thiazole derivatives were synthesized using dienolone acetate as the parent molecule.
