Chili () consumption is often suggested, and using functional food cultivars is the most effective strategy post COVID-19 pandemic. Controlling chili breeding activity is one of the most effective methods to produce new hybrid varieties. However, the general combining ability (GCA), specific combining ability (SCA), and heterotic effect of functional biochemicals (polyphenol content, antioxidant activities, and α-glucosidase inhibitory compounds) remain poorly known in .

Article Synopsis
  • This study investigates the antioxidant potential of the plant Justicia gendarussa (gendarussa) and how different nitrogen fertilizer doses affect its biological activity and secondary metabolite production.
  • Gendarussa has shown promising antioxidant activity, and while higher nitrogen doses increased plant weight, the optimal dose for enhancing metabolites was found to be 90 kg/ha, as indicated by metabolomics analysis.
  • Various assays (DPPH, ABTS, FRAP, CUPRAC) were utilized to assess antioxidant effects, revealing no significant differences across nitrogen treatments, and a total of 48 metabolites were identified, with Gendarusin A being a prominent one.

This study presents a structural phylogenetic analysis of plant defensive peptides, revealing their evolutionary relationships, structural diversification, and functional adaptations. Utilizing a robust dataset comprising both experimental and predicted structures sourced from the RCSB Protein Data Bank and AlphaFold DB, we constructed a detailed phylogenetic tree to elucidate the distinct evolutionary paths of plant defensive peptide families. Our findings showcase the evolutionary intricacies of defensive peptides, highlighting their diversity and the conservation of key structural motifs critical to their antimicrobial or defensive functions.

The antioxidant potential of (wungu leaves), an indigenous shrub plant extensively used in traditional medicine in Indonesia, was investigated in this study. The research focused on a comprehensive evaluation of total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric-reducing antioxidant power (FRAP) across various plant parts, including roots, stems, and flowers, which had been underexplored in prior studies. The ethanol extract derived from wungu flowers and leaves demonstrated notable antioxidant potential, characterized by elevated TPC (12.

Article Synopsis
  • - The research aimed to explore the diversity of okra genotypes in Indonesia, focusing on both their quantitative (e.g., yield) and qualitative characteristics, to support future plant breeding programs for enhanced productivity and anti-diabetic potential.
  • - A randomized block design was used to study 20 okra genotypes across 60 experimental units, with data analyzed using various statistical tools, revealing significant differences among genotypes based on characteristics like fruit yield, leaf width, and carpel thickness.
  • - Cluster analysis identified three distinct groups of genotypes, highlighting the genetic diversity present in okra, which can guide future breeding efforts to select the most promising varieties for cultivation.
