B Vitamins: An Update on Their Importance for Plant Homeostasis

Annual Review of Plant Biology, Journal Year: 2024, Volume and Issue: 75(1), P. 67 - 93

Published: March 1, 2024

B vitamins are a source of coenzymes for vast array enzyme reactions, particularly those metabolism. As metabolism is the basis decisions that drive maintenance, growth, and development, vitamin–derived key components facilitate these processes. For over century, we have known about essential compounds elucidated their pathways biosynthesis, repair, salvage, degradation in numerous organisms. Only now beginning to understand importance regulatory processes, which becoming an important topic plants. Here, I highlight discuss emerging evidence on how integrated into vital from energy generation nutrition gene expression, thereby contribute coordination growth developmental programs, concern maintenance stable state, foundational tenet plant homeostasis.

Abstract Agriculture-oriented microbiome studies try to develop microbiota beneficial their plant hosts. This positive goal extends the soil quality driving growth and disease resistance. In research aimed at identifying causes of this action, a common interpretation is that microbes will synthesize metabolites useful view assumes important microbial are exported for use by Yet, seems unlikely essential metabolites, without counterpart imported from plants, as corresponding syntheses would often involve consumption resources explicit benefit microbes. Illustrating function with example Bacilli Subtilis clade, we emphasize here most direct access contents cells through cell lysis, phenomenon linked process sporulation. also releases macromolecules digested in environment, releasing key such queuine, an base analog present anticodon some transfer RNAs. overlooked importance lysis could be major cause ubiquitous presence bacteriophages microbiota.

Two pyridoxal phosphate homeostasis proteins are essential for management of the coenzyme pyridoxal 5′-phosphate in Arabidopsis

The Plant Cell, Journal Year: 2024, Volume and Issue: 36(9), P. 3689 - 3708

Published: July 2, 2024

Abstract Coenzyme management is important for homeostasis of the pool active metabolic enzymes. The coenzyme pyridoxal 5′-phosphate (PLP) involved in diverse enzyme reactions including amino acid and hormone metabolism. Regulatory proteins that contribute to PLP remain be explored plants. Here, we demonstrate importance annotated as (PLPHPs) controlling Arabidopsis (Arabidopsis thaliana). A systematic analysis indicates while most organisms across kingdoms have a single PLPHP homolog, Angiosperms two. PLPHPs from bind exist monomers, contrast reported PLP-dependent enzymes, which multimers. Disrupting function both homologs perturbs vitamin B6 (pyridoxine) content, inducing deficit accompanied by light hypersensitive root growth, unlike biosynthesis mutants. Micrografting studies show can relieved distally between shoots roots. Chemical treatments probing reactions, notably those auxin ethylene, provide evidence dynamic PLP.

Variation of vitamin B contents in maize inbred lines: Potential genetic resources for biofortification

Frontiers in Nutrition, Journal Year: 2022, Volume and Issue: 9

Published: Oct. 21, 2022

Vitamin B and its derivatives possess diverse physiological functions are essential micronutrients for humans. Their variation in crops is important the identification of genetic resources used to develop new varieties with enhanced vitamin B. In this research, remarkable variations were observed kernels 156 maize inbred lines, ranging from 107.61 2654.54 μg per 100 g B1, 1.19–37.37 B2, 19.60–213.75 B3, 43.47–590.86 B5, 138.59–1065.11 B6. Growing inbreeds Hainan Hebei provinces China revealed environmental genotype interactions among these vitamins correlations between them grain. Several lines identified as good sources promising germplasms breeding, namely By855 Si273 overall rich all studied vitamins, GY386B CML118 specially enriched The present study can assist breeders germplasm biofortification offer people nutritious foods.

Dietary B vitamins and glioma: A case–control study based on Chinese population

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: March 2, 2023

Background Dietary antioxidants have long been thought to be likely prevent the development of gliomas. Previous studies reported vitamin A, C, and E protective effects against B vitamins, one main vitamins in diet, are closely related human health, but association with gliomas has rarely reported. Objective This study aimed evaluate relationship between five glioma. Methods In this Chinese population-based case–control study, 506 glioma cases matched (age sex) controls were included. The dietary intake participants was assessed using a valid 111-item food frequency questionnaire. calculated based on participants’ information from logistic regression model used examine glioma, restriction cubic spline evaluated dose–response two. Results After adjusting for confounding factors, thiamine (OR = 0.09, 95%CI: 0.05–0.20), riboflavin 0.12, 0.06–0.25), nicotinic acid 0.24, 0.12–0.47), folate 0.07, 0.03–0.15) biotin 0.14, 0.07–0.30) highest tertile associated significantly decreased risk compared lowest tertile. results different pathological types grades different. restricted function showed significant relationships When exceeded specific intake, did not change. Conclusion Our suggests that higher thiamine, riboflavin, acid, consistent among populations. future, prospective should conducted better validate
