ABSTRACT Food security is defined as uninterrupted access to food that meets people's dietary needs. One essential trace element of a complete diet zinc, which vital for various processes, including growth, development, and the immune response. The estimated global prevalence zinc deficiency around 30%. Meat meat products provide an abundant also bioavailable source zinc. However, in developing countries, restricted, developed consumption has declined ethical environmental reasons. potential arises from ( i ) low concentrations this plant‐based diets, ii poor absorption human intestine, iii risk uptake toxic metals together with ones. This review summarises current knowledge concerning type 4 metallothioneins, represent promising targets biofortification. We describe their place route soil seed, expression patterns, role plants, three‐dimensional protein structure how affects selectivity towards aims comprehensive theoretical basis use plant metallothioneins create zinc‐biofortified crops.

Metabolomic Analysis of Lycoris radiata across Developmental and Dormancy Stages

Horticulturae, Journal Year: 2024, Volume and Issue: 10(6), P. 636 - 636

Published: June 13, 2024

The Lycoris radiata (L’ Herit.) Herb. is a perennial bulbous plant characterized by its high ornamental and medicinal value, exhibiting unique growth rhythm where the flower leaf do not coexist period of summer dormancy. However, metabolic response to various developmental stages remains unclear. To address this gap, we conducted non-targeted metabolomic analysis spanning six L. radiata. results showed that most differentially accumulated metabolites (DAMs) demonstrated enrichment predominantly in carbohydrate amino acid metabolism pathways, with former being more active during vegetative latter reproductive stages. proportion DAMs categorized under “quaternary ammonium salts”, “tricarboxylic acids derivatives”, “fatty conjugates”, “pyrimidine nucleotide sugars” was notably higher comparisons between flowering dormancy than other comparative groups. Furthermore, involved KEGG pathways C5-branched dibasic lysine biosynthesis were uniquely identified transition from Dormancy Flowering. associated “linoleic derivatives” “pyridines pyridine leafing out versus comparison glycolysis/gluconeogenesis pathway enriched phase. This study provided an in-depth view metabolite changes over annual cycle, enriching our understanding regulatory mechanisms governing development, dormancy, flowering.

Molecular characterization and expression patterns of MTP genes under heavy metal stress in mustard (Brassica juncea L.)

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 1, 2024

Members of the Metal Tolerance Protein (MTP) family are critical in mediating transport and tolerance divalent metal cations. Despite their significance, understanding MTP genes mustard (Brassica juncea) remains limited, especially regarding response to heavy (HM) stress. In our study, we identified gene sets Brassica rapa (17 genes), nigra (18 B. juncea (33 genes) using HMMER (Cation_efflux; PF01545) BLAST analysis. For 33 BjMTPs, a comprehensive bioinformatics analysis covering physicochemical properties, phylogenetic relationships, conserved motifs, protein structures, collinearity, spatiotemporal RNA-seq expression, GO enrichment, expression profiling under six HM stresses (Mn2+, Fe2+, Zn2+, Cd2+, Sb3+, Pb2+) were carried out. According findings characteristics, tree, allopolyploid juncea's inherited from its progenitors, nigra, with minimal loss during polyploidization. BjMTP exhibited promoter elements, patterns across subgroups, consistent seven evolutionary branches (G1, G4–G9, G12) MTPs. Further, successfully specific crucial cis-regulatory elements associated BjMTPs stresses. These may contribute genetic improvement for enhanced tolerance, facilitating remediation HM-contaminated areas.

Genome-wide exploration of MTP gene family in mustard (Brassica juncea L.): evolution and expression patterns during heavy metal stress

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: May 2, 2024

Members of the Metal Tolerance Protein (MTP) family are critical in mediating transport and tolerance divalent metal cations. Despite their significance, little is known about MTP genes mustard (Brassica juncea), particularly relation to how they react HM stress. In our study, we identified MTP gene sets Brassica rapa (17 genes), nigra (18 B. juncea (33 genes) using HMMER tool (Cation_efflux; PF01545) BLAST analysis. Then, for 33 BjMTPs, carried out a detailed bioinformatics analysis covering physicochemical properties, phylogenetic relationships, conserved motifs, protein structures, collinearity, spatiotemporal RNA-seq expression, GO enrichment, expression profiling under six stresses (Mn²⁺, Fe²⁺, Zn²⁺, Cd²⁺, Sb³⁺, Pb²⁺). According findings characteristics tree, allopolyploid juncea’s genes were inherited from its progenitors, nigra, with minimal gene loss during polyploidization. The BjMTP exhibited promoter elements, patterns that aligned seven evolutionary branches (G1, G4-G9, G12). Further, by co-expression analysis, core gene-specific modules BjMTPs were found. treatments consistently upregulated BjA04.MTP4, BjA09.MTP10, BjB01.MTP5 genes, indicating roles enhancing juncea. These discoveries may contribute genetic improvement juncea's tolerance, which would facilitate remediation HM-contaminated areas.
