AI Article Synopsis
- This study explores the genetic factors influencing the color and patterns of cowpea seed coats using a genome-wide association study (GWAS) approach.
- Researchers examined 296 cowpea varieties with 110,000 single nucleotide polymorphisms (SNPs) and identified eight distinct seed coat patterns.
- The analysis revealed 13 significant SNP markers and 23 candidate genes, with four genes likely directly affecting seed coat color, providing insights for future cowpea breeding programs to meet consumer demands.
Article Abstract
This study investigates the genetic determinants of seed coat color and pattern variations in cowpea (), employing a genome-wide association approach. Analyzing a mapping panel of 296 cowpea varieties with 110,000 single nucleotide polymorphisms (SNPs), we focused on eight unique coat patterns: (1) Red and (2) Cream seed; (3) White and (4) Brown/Tan seed coat; (5) Pink, (6) Black, (7) Browneye and (8) Red/Brown Holstein. Across six GWAS models (GLM, SRM, MLM, MLMM, FarmCPU from GAPIT3, and TASSEL5), 13 significant SNP markers were identified and led to the discovery of 23 candidate genes. Among these, four specific genes may play a direct role in determining seed coat pigment. These findings lay a foundational basis for future breeding programs aimed at creating cowpea varieties aligned with consumer preferences and market requirements.

Seeds are complex structures composed of three regions, embryo, endosperm, and seed coat, with each further divided into subregions that consist of tissues, cell layers, and cell types. Although the seed is well characterized anatomically, much less is known about the genetic circuitry that dictates its spatial complexity. To address this issue, we profiled mRNAs from anatomically distinct seed subregions at several developmental stages.

The present investigation deals with comparisons drawn among three types of different mustard seed coat colors, namely, Black (), Brown (), and White (), with respect to protein's bio-availability through pepsin digestibility, with and without the involvement of major anti-nutritional factors (glucosinolate type AITC, Allylisothiothiocyanate) and relative food functions. These are validated by means of crude protein determination, precipitated protein isolate preparation for evaluating the fat absorption capacity (FAC), emulsifying activity (EA), emulsion stability (ES), whippability, foam stability (FS), the nitrogen solubility index (NSI), and the protein dispersibility index (PDI). The results indicate that the partial removal of glucosinolates from brown mustard (0.

During the last decades, Arabidopsis seed mucilage has been extensively studied to gain insight into the metabolism of pectin, hemicellulose and cellulose. This review aims to provide a comprehensive examination of the techniques used to understand the composition and structure of mucilage. Moreover, we present novel findings from mucilage analysis, including the separation of pectic domains within the mucilage, offering a fresh perspective on utilizing traditional techniques to analyze mucilage mutant lines.

Article Synopsis
- Hepatocellular carcinoma (HCC) is a common and aggressive cancer with high recurrence rates, making new treatment options crucial.
- Quinoa bran protein hydrolysate (QBPP) has been found to effectively inhibit the growth of HCC cells while showing little toxicity to normal liver cells.
- QBPP works by inducing apoptosis and preventing HCC cell migration, suggesting it could be a promising dietary supplement for HCC prevention and treatment.

Article Synopsis
- Yellow seed coat color (SCC) is linked to higher seed oil content (SOC) and lower seed lignocellulose content (SLC), but no dominant yellow SCC genes were previously known.
- A dominant yellow SCC gene called N53-2 was identified in a study using a double haploid population from N53-2 and a black seed coat material, revealing thousands of expression quantitative trait loci (eQTLs) and specific trans-eQTL hotspots.
- Transgenic experiments confirmed that the newly discovered allele produces yellow SCC seeds with significantly higher SOC and lower SLC, offering promising prospects for breeding rapeseed with desirable traits.
