Nickel (Ni) is an essential nutrient for plants, but excessive amounts can be toxic. Ni competes with iron (Fe) in vivo, raising the possibility that competitively taken up via Fe uptake system plants. Here, we show evidence AtIRT1, primary Fe(2+) transporter root, mediates accumulation Arabidopsis thaliana. In hydroponic cultures, excess exposure increased and relative transcription level of AtIRT1 roots, indicating induces expression roots. An Fe-deficient treatment suggesting was absorbed...
Protein phosphorylation events play key roles in maintaining cellular ion homeostasis higher plants, and the regulatory of these Na+ K+ transport have been studied extensively. However, mechanisms governing Mg2+ plants remain poorly understood, despite vital function. A member subclass III sucrose nonfermenting-1-related protein kinase2 (SnRK2), SRK2D/SnRK2.2, functions as a positive regulator abscisic acid (ABA)-mediated signaling response to water deficit stresses Arabidopsis (Arabidopsis...
Summary The alteration of transcript structure contributes to transcriptome plasticity. In this study, we analyzed the genome‐wide response exon combination patterns deficiencies in 12 different nutrients Arabidopsis thaliana roots. RNA sequencing analysis and bioinformatics using a simulation survey revealed more than 600 genes showing varying combinations. overlap between differential expression ( DE ) DC was notably low. Additionally, gene ontology showed that functions were not shared...
Summary Hakea laurina , a woody Proteaceae, naturally occurs in severely phosphorus (P)‐impoverished habitats southwest Australia. It develops distinctive cluster roots that exhibit high capacity for carboxylate exudation and acid phosphatase activity, contributing to its P acquisition. However, the molecular mechanisms underlying these physiological functions remain poorly understood. We explored cluster‐root transcriptome using de novo RNA‐Seq identified Aluminum‐activated Malate...
Excessive accumulation of nickel (Ni) can be toxic to plants. In Arabidopsis thaliana, the Fe2+ transporter, iron (Fe)-regulated transporter1 (IRT1), mediates Fe uptake and also implicates in Ni2+ at roots; however, underlying mechanism remains unelucidated. present study, we found that zinc (Zn) deficient conditions resulted increased Ni plants, particularly roots, A. thaliana. order elucidate mechanisms correlating condition, traced 63Ni isotope response Zn (i) deficiency induces...
Long intergenic noncoding RNAs (lincRNAs) play critical roles in transcriptional and post-transcriptional regulation of gene expression a wide variety organisms. Thousands lincRNAs have been identified plant genomes, although their functions remain mostly uncharacterized. Here, we report genome-wide survey involved the response to low-nutrient conditions Arabidopsis thaliana. We used RNA sequencing data derived from A. thaliana roots exposed low levels 12 different nutrients. Using...
Excessive amounts of nickel (Ni) can be toxic for plants. Recently, we reported that IRT1, the primary iron (Fe) uptake transporter in roots, meditates excess Ni accumulation Arabidopsis thaliana. We also found exposure increases IRT1 expression suggesting is further induced by stress. Here, show induces not only but FRO2, a ferric reductase root epidermis, and FIT, transcription factor regulating genes involved Fe homeostasis including FRO2. This result suggests an Fe-deficient response...
One mechanism of arsenic detoxification in plants is synthesis phytochelatins from glutathione a sulfur-dependent manner. This study examined the contribution sulfate transporter, SULTR1;2, tolerance terms sulfur metabolism Arabidopsis thaliana (L.) Heynh. Comparative analysis SULTR mutants showed that defective mutations SULTR1;2 resulted an increased sensitivity, both shoots and roots, establishing required for tolerance. We subsequently quantified total content levels compounds...
Abstract Rice production is seriously affected by saline-alkaline stress worldwide. To elucidate the tolerance mechanisms in a novel tolerant rice variety, Shwe Nang Gyi (SNG), we investigated ion accumulation SNG and Koshihikari (KSH), which sensitive candidates for inducible genes using RNA-seq. had superior capacity, such as K Zn, compared to KSH. In contrast, accumulated same level of Na content its leaf blades KSH despite higher dry weight blades. We further found that expression...
A number of metal hyperaccumulator plants, including nickel (Ni) hyperaccumulators, have been identified in the genus Noccaea. The ability to accumulate Ni shoots varies widely among species and ecotypes this genus; however, little is known about molecular mechanisms underlying intra- inter-specific variation. Here, hydroponic culture, we compared accumulation patterns between N. japonica, which originated Ni-enriched serpentine soils Mt. Yubari (Hokkaido, Japan), caerulescens ecotype...
Glucosinolates (GSLs) are sulfur (S)-rich specialized metabolites present in Brassicales order plants. Our previous study found that GSL can function as a S source Arabidopsis seedlings via its catabolism catalyzed by two β-glucosidases (BGLUs), BGLU28 and BGLU30. However, profiles plants vary among growth stages organs, the potential contribution of BGLU28/30-dependent at reproductive stage needs verification. Thus, this study, we assessed growth, metabolic transcriptional phenotypes mature...
Our earlier study demonstrated that the landrace of Japonica rice, Akamai exhibits low-P (phosphorous) tolerance mechanisms compared to conventional type cultivar, Koshihikari. The present examined genotypic difference yield, plasticity root growth, and internal utilization acquired P (allocation pattern biomass among different vegetative reproductive organs) two contrasting cultivars in response P-deficiency. Each cultivar was grown until maturity with (+P) without (–P) supply pots (two...
The manipulation of seed phosphorus is important for seedling growth and environmental P sustainability in agriculture. mechanism regulating content seed, however, poorly understood. To study regulation total P, we focused on phytic acid (inositol hexakisphosphate; InsP₆) biosynthesis-related genes, as InsP₆ a major storage form seeds. rice (Oryza sativa L.) low mutant lpa1-1 has been identified homolog archael 2-phosphoglycerate kinase. might act an inositol monophosphate kinase, which...
RAB11 GTPases, widely conserved members of RAB small have evolved in a unique way plants; plant has notable diversity compared with animals and yeast. Recently, we shown that RABA1, subgroup Arabidopsis group, are required for salinity stress tolerance. To obtain clue to understand its underlying mechanism, here investigate whether RABA1 regulates sodium transport across the plasma membrane accumulation vacuole. The results indicate raba1 quadruple mutant is not defective import...
Arbuscular mycorrhizas support nutrient uptake from the soil. Here we demonstrated Iron-59 (59Fe) in maize (Zea mays L.) through mycorrhizal roots. colonization did not strongly induce Strategy II-related genes, but putative iron transporter OPT8a and OPT8b, were induced by more than 50-fold. Our data provide a previously undescribed gene expression mode related to system of II plants.
Metabolomic studies conducted for evaluating cancer pathogenesis and progression by monitoring the amino acids metabolic balance hold great promise assessing current future anticancer treatments. We performed a comprehensive quantification of 21 concentrations in cultured human colorectal adenocarcinoma cells treated with drugs 5-fluorouracil, irinotecan, cisplatin. A precolumn fluorescence derivatization-HPLC method involving 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate was used. Amino...
Potassium (K) is a major plant nutrient. K+ taken up by channel and transporter proteins in roots translocated from to shoots via the xylem. In Arabidopsis thaliana, NPF7.3 mediates loading into xylem transcription factor MYB59 responsible for expression. Here, we demonstrate that regulated alternative splicing response K availability. Three isoforms of are detected roots: an isoform with first intron spliced out encodes protein full DNA-binding motif (MYB59α), two retained partially or...
