GLKs directly regulate carotenoid biosynthesis via interacting with GBFs in plants

New Phytologist, Год журнала: 2025, Номер unknown

Опубликована: Фев. 14, 2025

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

Identification of photosynthetic pigment contents related genes in peanut (Arachis hypogaea L.) by GWAS and RNA-seq

Опубликована: Апрель 3, 2025

Photosynthetic pigments are indispensable for light absorption and electron transfer in photosynthesis, which is essential increasing crop productivity. However, genetic basis of photosynthetic pigment contents peanuts (Arachis hypogaea L.) at seedling flowering stages remains poorly understood. In this study, an association panel 241 peanut accessions was assayed four contents, including chlorophyll a (Chl a), b b), total + b) carotenoids (Car) across five environments. A 2,110,659 high-quality single nucleotide polymorphisms (SNPs) were obtained by whole-genome re-sequencing. genome-wide study performed based on the best linear unbiased estimation values contents. total, 23 45 quantitative trait loci (QTLs) associated with stages, respectively, eight QTLs multiple traits. Thirty-two genes identified within these QTL regions. Furthermore, through RNA-seq analysis two contrasting 3829 4972 differentially expressed detected respectively. Two candidate genes, Arahy.YWY61J Arahy.VMJ95M, differently stages. Haplotype suggested that involved Chl contents; Arahy.VMJ95M gene Car synthesis leaves. These findings will contribute to understanding molecular mechanisms underlying variations benefits improvement efficiency using marker-assisted breeding peanuts.

ORANGE family proteins: multifunctional chaperones shaping plant carotenoid level, plastid development, stress tolerance, and more

Molecular Horticulture, Год журнала: 2025, Номер 5(1)

Опубликована: Май 9, 2025

Abstract ORANGE (OR) family proteins are DnaJE1 molecular chaperones ubiquitous and highly conserved in all plant species, indicating their important roles growth development. OR have been found to exert multiple functions regulating carotenoid chlorophyll biosynthesis, plastid development, stress tolerance, with additional expected be discovered. As chaperones, directly influence the stability of target via holdase activity may perform other through unknown mechanisms. Exploration has uncovered novel mechanisms underlying core metabolism pathways expanded our understanding processes linked Continued investigation will not only reveal new but also provide pioneering tools for crop improvement. Thus, offer a distinctive opportunity comprehend modulating various metabolic developmental exemplify importance development adaptability. This review briefly details history proteins, highlights recent advancements myriad functions, discusses prospects this fascinating group towards generating innovative, more nutritious, resilient crops alongside agronomically traits.

Assessment of the CO₂ uptake capabilities and growth responses of selected grass species under elevated CO2

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Май 9, 2025

Screening plants for their CO₂ uptake efficiency could contribute to better species, which be an asset future mitigation programs. This study evaluated the flux in within a CO₂-controlled chamber having grass Megathyrsus maximus, Saccharum arundinaceum, Cymbopogon flexuosus, Chrysopogon zizanioides, Arundo donax and Pennicetum pedicellatum. The day of (related photosynthesis) night respiration) chambers were estimated. net exchange species was also calculated assess actual capability carbon sequestration. Regarding flux, S. arundinaceum (-338.64 ± 65.01ppm) showed performance, followed by M. A. donax, P. pedicellatum, C. flexuosus zizanioides. However, higher CO₂ (-27.63 11.42%) due its lower respiratory contribution at night. While concerning overall morphology on last order, whereas maximus top. An equation derived estimate per plant biomass, especially studies, more dry weight (8.008g Kg), Broad understanding from is that efficient curbing since had it employed with proper supplementation nitrogen.

Effects of Different LED Light Quality Combinations on Nutritional Quality and Physiological Characteristics of Celery

Horticulturae, Год журнала: 2025, Номер 11(5), С. 524 - 524

Опубликована: Май 13, 2025

Light is essential for vegetable growth, with varying combinations of light quality affect differently on plant growth and development. In order to clarify the optimal combination celery LEDs, under hydroponic full LED conditions, this study investigated distinct have various impacts using “Hongcheng Red Celery” as test material. Red-blue (R:B = 3:1, control), red-blue-purple (R:B:P 3:1:1, purple (P)), red-blue-green (R:B:G green (G)), red-blue-yellow (R:B:Y yellow (Y)), red-blue-far-red (R:B:FR far-red (FR)) conditions were set up in experiment, plants treated 45 days. The findings indicated that best was achieved RBP, while RBG inhibited celery. chlorophyll a total contents leaves increased significantly by RBP treatments compared RB. addition, net photosynthetic rate, stomatal conductance, transpiration rate highest RBP. treatment, soluble protein, vitamin C, phenols, flavonoids, Ca, Fe, Zn petioles higher than other treatments. And anthocyanins content reduced nitrate content. treatment activities apigenin synthesis-related enzymes CHS, FNS, ANS, up-regulated expression related genes summary, more favorable nutrient synthesis.
