nicotianamine

01/01/2009 - "The fact that nicotianamine is induced under Cu starvation and not under Cu excess, is in contrast to similar studies indicating species-specific reactions. "
01/01/2009 - "However, the induction of nicotianamine under Cu starvation is in line with recent molecular data of the role of nicotianamine in intracellular Cu delivery."

01/01/2022 - "The homologous genes of bread wheat from several groups were selected for gene expression studies exploring the tight control of iron uptake, translocation rate and accumulation in leaves and roots, and comprised the following: (1) S-adenosylmethionine synthase (SAMS), nicotianamine synthase (NAS1), nicotianamine aminotransferase (NAAT), deoxymugineic acid synthetase (DMAS), involved in the synthesis and release of phytosiderophores; (2) transcription factor basic helix-loop-helix (bHLH); (3) transporters of mugineic acid (TOM), involved in long-distance iron transport; (4) yellow stripe-like (YSlA), and the vacuolar transporter (VIT2), involved in intracellular iron transport and storage; and lastly (5) natural resistance-associated macrophage protein (NRAMP) and ferritin (Fer1A). "

01/01/2013 - "NFP plants showed increased sensitivity to iron-deficiency conditions and changes in the expression of endogenous genes involved in nicotianamine (NA) metabolism, in comparison to their non-transgenic siblings (NTS). "
01/01/2009 - "Increased sensitivity to iron deficiency in Arabidopsis thaliana overaccumulating nicotianamine."
05/09/2008 - "Several genes up-regulated by iron deficiency, including the Fe(II)-nicotianamine transporter gene OsYSL2, were less induced by iron deficiency in the RNAi rice of IDEF2, suggesting that IDEF2 is involved in the regulation of these genes. "
02/01/2012 - "Vacuolar nicotianamine has critical and distinct roles under iron deficiency and for zinc sequestration in Arabidopsis."
01/01/2020 - "The constitutive iron-deficiency response in the nas mutant because of iron accumulation in shoots was significantly rescued by grafting of wild-type shoots or roots, suggesting that shoot- and root-ward translocation of nicotianamine-iron complexes and/or nicotianamine is essential for iron mobilization. "

01/01/2022 - "Maize Interveinal Chlorosis 1 links the Yang Cycle and Fe homeostasis through Nicotianamine biosynthesis."
06/01/2012 - "The quadruple nas4x-2 mutant of Arabidopsis thaliana cannot synthesize any nicotianamine, shows strong leaf chlorosis, and is sterile. "
10/01/2019 - "NH4+ also increases soluble Fe levels in shoots by upregulating genes involved in Fe translocation, such as FRD3 (FERRIC REDUCTASE DEFECTIVE3) and NAS1 (NICOTIANAMINE SYNTHASE1), hence, alleviating leaf chlorosis. "

08/01/2021 - "aureus is equipped by advanced virulence-regulatory circuits of metal acquisition like Cnt that acquires metals at infection sites by utilizing a nicotianamine-like metallophore staphylopine. "
06/01/2007 - "Levels of S-adenosylmethionine decarboxylase, caffeic acid 3-O-methyltransferase, 1-aminocyclopropane-1-carboxylate oxidase mRNA, but not phosphoethanolamine N-methyltransferase and nicotianamine synthase mRNA, were up-regulated after infection and showed similar expression patterns to genes involved in the pathways of generation of methyl units, revealing possible routes of methyl transfer towards polyamine, lignin and ethylene biosynthesis rather than glycine betaine and nicotianamine in response to Bgt attack.
