Magnesium (Mg 2+ ) is pivotal for the vitality, yield, and quality of horticultural crops. Central to plant physiology, Mg powers photosynthesis as an integral component chlorophyll, bolstering growth biomass accumulation. Beyond basic growth, it critically affects crop factors, from chlorophyll synthesis taste, texture, shelf life. However, Mg2 + deficiency can cripple yields impede development. Transporters (MGTs) orchestrate dynamics, with notable variations observed in species such Cucumis sativus, Citrullus lanatus , Citrus sinensis . Furthermore, key fortifying plants against environmental stressors diseases by reinforcing cell walls spurring defense substances. A burgeoning area research application magnesium oxide nanoparticles (MgO-NPs), which, owing their nanoscale size high reactivity, optimize nutrient uptake, enhance stress resilience. Concurrently, modern breeding techniques provide insights into dynamics develop crops improved efficiency resilience deficiency. Effective management through soil tests, balanced fertilization, pH adjustments holds promise maximizing health, productivity, sustainability. This review unravels nuanced intricacies physiology genetics, its interplay external serving a cornerstone those keen on harnessing potential excellence.

Abstract Carotenoids are essential for photosynthesis and photoprotection. Plants must evolve multifaceted regulatory mechanisms to control carotenoid biosynthesis. However, the regulators conserved among plant species remain elusive. Phytoene synthase (PSY) catalyzes highly regulated step of carotenogenesis geranylgeranyl diphosphate (GGPPS) acts as a hub interact with GGPP-utilizing enzymes synthesis specific downstream isoprenoids. Here, we report function Nudix hydrolase 23 (NUDX23), domain-containing protein, in post-translational regulation PSY GGPPS NUDX23 expresses Arabidopsis (Arabidopsis thaliana) leaves. Overexpression significantly increases protein levels production, whereas knockout dramatically reduces their abundances accumulation Arabidopsis. regulates biosynthesis via direct interactions chloroplasts, which enhances stability large PSY–GGPPS enzyme complex. was found co-migrate proteins be required complex assembly. Our findings uncover mechanism underlying plants offer promising genetic tools developing carotenoid-enriched food crops.

Using beneficial microorganisms, such as purple non-sulfur bacteria (PNSB), has shown enormous potential for improving plant growth and agricultural production. However, the full extent of their benefits interactions with practices is yet to be fully understood. The present study aimed investigate use PNSB in crop rotation practice, focusing on its impact rice yield. experiment was conducted over two cropping seasons, djulis grown between a crop. shows that treatment increased concentration 5-aminolevulinic acid (5-ALA) plants, indicating enhanced photosynthesis. Moreover, when combined rotation, remarkably improved soil fertility. These resulted substantial increases tiller numbers (163%), leaf chlorophyll content (13%), lodging resistance (66%), compared untreated plants. also higher productive tillers per hill (112%), average grain (65%), fertility (26%). This led yield shoot dry weight (15%), harvest index (37%). findings clearly suggest incorporation strategies can significantly augment crops. insights, pivotal sustainable cultivation, hold simultaneously tackle pressing issues global food security climate change.

BoaBZR1.1 mediates brassinosteroid-induced carotenoid biosynthesis in Chinese kale

Horticulture Research, Год журнала: 2024, Номер 11(6)

Опубликована: Апрель 9, 2024

Brassinazole resistant 1 (BZR1), a brassinosteroid (BR) signaling component, plays pivotal role in regulating numerous specific developmental processes. Our study demonstrated that exogenous treatment with 2,4-epibrassinolide (EBR) significantly enhanced the accumulation of carotenoids and chlorophylls Chinese kale (Brassica oleracea var. alboglabra). The underlying mechanism was deciphered through yeast one-hybrid (Y1H) dual-luciferase (LUC) assays, whereby BoaBZR1.1 directly interacts promoters BoaCRTISO BoaPSY2, activating their expression. This effect further validated overexpression calli plants, both which exhibited increased carotenoid accumulation. Additionally, qPCR analysis unveiled upregulation chlorophyll biosynthetic genes T1 generation BoaBZR1.1-overexpressing plants. These findings underscored significance BoaBZR1.1-mediated BR suggested potential for enhancing nutritional quality genetic engineering BoaBZR1.1.

Carotenoids are essential for photosynthesis and photoprotection in photosynthetic organisms, which widely used food coloring, feed additives, nutraceuticals, cosmetics, pharmaceuticals. Carotenoid biofortification crop plants or algae has been considered as a sustainable strategy to improve human nutrition health. However, the regulatory mechanisms of carotenoid accumulation still not systematic particularly scarce algae. This article focuses on through factors (transcription proteins), demonstrating complexity homeostasis regulation carotenoids, mainly including transcriptional primary mechanism, subsequent post-translational regulation, cross-linking with other metabolic processes. Different organs different plant/algal species usually have specific biosynthesis, storage, degradation carotenoids response environmental developmental signals. In algae, regulators such MYB, bHLH, MADS, bZIP, AP2/ERF, WRKY, orange proteins can be involved metabolism. And many more regulators, networks, need explored.

Carotenoid sequestration protein FIBRILLIN participates in CmOR-regulated β-carotene accumulation in melon

PLANT PHYSIOLOGY, Год журнала: 2023, Номер 193(1), С. 643 - 660

Опубликована: Май 26, 2023

Chromoplasts are plant organelles with a unique ability to sequester and store massive carotenoids. have been hypothesized enable high levels of carotenoid accumulation due enhanced sequestration or substructure formation. However, the regulators that control component formation in chromoplasts remain unknown. In melon (Cucumis melo) fruit, β-carotene is governed by ORANGE (OR), key regulator for chromoplasts. By using comparative proteomic analysis variety its isogenic line low-β mutant defective CmOr impaired chromoplast formation, we identified protein FIBRILLIN1 (CmFBN1) as differentially expressed. CmFBN1 expresses highly fruit tissue. Overexpression transgenic Arabidopsis (Arabidopsis thaliana) containing ORHis genetically mimics significantly enhances accumulation, demonstrating involvement CmOR-induced accumulation. Both vitro vivo evidence showed CmOR physically interacts CmFBN1. Such an interaction occurs plastoglobules results promoting greatly stabilizes CmFBN1, which stimulates plastoglobule proliferation subsequently Our findings show directly regulates suggest fundamental role facilitating sequestration. This study also reveals important genetic tool further enhance OR-induced crops.

Summary Carotenoids are vital photosynthetic pigments for plants. Golden2‐like transcription factors (GLKs) widely recognized as major regulators of Chl biosynthesis and chloroplast development. However, despite GLKs being subjected to intensive investigations, whether directly regulate carotenoid the molecular mechanisms by which transcriptionally activate their target genes remain unclear. Here, we report that in a G‐box binding factor (GBF)‐dependent manner Arabidopsis. Both vitro vivo studies reveal physically interact with GBFs phytoene synthase (PSY) , gene encoding rate‐limiting enzyme biosynthesis. While possess transactivation activity, they depend on bind motif modulate PSY expression. Loss impairs GLK function regulating Since is an enriched promoters GLK‐regulated genes, GLK–GBF regulatory module likely serves common mechanism underlying pigment Our findings uncover novel machinery biosynthesis, discover transcriptional regulation GLKs, divulge important coordinate synthesis
