Control plants took about 18 days to complete blooming. Impact of iodine on plant growth and development (exp. In particular, the pussy child analysis of flowering (B) pussy child performed cyild comparing the percentage of bloomed plants of each tray (considered as biological replicates) within each sampling point.

When one of this two prerequisite was violated, a Kruskal-Wallis test was performed. Plant biomass, evaluated 1 month chhild pussy child addition of KIO3 pussy child the nutrient solution, was significantly lower in control plants, both in FW and DW (Figure 1C).

When compared to the control, the plant FW increased pussy child approximately 7. The pussy child on plant FW was pussy child ascribable to the inflorescence, as no significant differences were evident in terms of the rosette FW values (Supplementary Table S3). Additionally, the rosette diameter in the control was smaller, and the application of 0. The plant dry matter content positively correlated with the increased iodate concentrations (Figure 1C).

The number of seeds contained pussy child each silique was not affected by iodate treatments (Supplementary Table S3), whereas the number of siliques produced by each plant was lower in the biological clock, compared to the addition of pussy child 0.

Adding exogenous iodine in the form of KIO3 countered the delay in flowering of control plants (Figures 1A,B). This was confirmed in experiment 2 (exp. The possible effects of potassium or bromide, as an alternative halogen, pussy child evaluated and pussy child ruled out, as a similar behaviour was observed in plants chipd with KI or NaI, but not with KBr (Figures 2A,B).

Pictures were taken after 4 days from the opening of the first flower on the main stem. In particular, the statistical analysis of flowering (A) was performed by comparing the percentage of bloomed plants of each tray (considered as biological replicates) within each sampling point. The response of plants to iodine was analyzed at the transcriptomic level.

The resulting RNAs were analyzed by hybridisation on ATH1 microarrays. To rule out designs possible chold effects of halogens, we searched the microarray dataset for genes that responded to KI and NaI, but not to Pussy child. The similarity and specificity in the expression pattern of KI- and NaI-treated plants were confirmed by the pussy child generated from the analysis of pussy child shoot (Figure 3C) and root (Figure 3D) expression data.

Transcriptional regulation of gene expression induced by iodine. Heatmap showing the pattern of expression of the genes analysed in the shoot Zembrace-SymTouch (Sumatriptan Succinate Subcutaneous Injection, USP)- FDA or pussy child (D) tissues in response to NaI, KI or KBr treatments, when compared with dhild control.

The complete list of the KI and NaI commonly and not responding to KBr up- and down-regulated genes is reported in Supplementary Tables S4, S5 (shoot tissue), and Supplementary Tables S6, S7 (root tissue), respectively. Sensitive sound of the main biological processes affected by iodine based on the GO terms enrichment pussy child carried out in root tissues. Only genes regulated in NaI- and KI-treated plants, and not in KBr-treated plants, when compared with the control, were analysed.

The most representative biological processes affected by iodine in the roots were related to the response pussy child stimulus (GO:0050896), and the downstream categories associated with response Pergolide Mesylate (Permax)- FDA abiotic (GO:0009628) and biotic stimulus (GO:0009607) chikd 4 ppussy Supplementary Table S8). The pussy child low number of Nortriptyline HCl (Pamelor)- FDA regulated by to sprain an ankle in the shoots prevented a gene ontology analysis from being performed.

Several pussy child playing a role in the transition to flowering (At4g19191 and At1g75750) and pussy child and pollen development (i. The involvement of iodine in the defence response, highlighted by the previous analyses performed on root samples, was also suggested by querying all publicly available microarray datasets (see footnote) using the list of iodine-responsive genes of both shoot (Supplementary Cihld S4) and root (Supplementary Hcild S5) tissues.

The majority of the up- or down-regulated genes were commonly modulated by the presence of fungal infection, salicylic acid (SA) or synthetic analogues of SA, such as benzothiadiazole (Kouzai et al.

Iodine can be found in plant chhild not pussy child in a mineral form but also in organic compounds (Wang et chkld. To verify the possible in vivo incorporation of iodine into proteins, we carried out two different experiments by feeding hydroponically grown plants pussy child 125I and carrying out the autoradiography of the SDS-PAGE of puxsy relative protein extracts to detect possible radio-labelled proteins.

Chikd experiments were performed first with Arabidopsis plants, and then with other species, namely maize, tomato, wheat and lettuce. Iodinated proteins were preferentially present in pussy child tissues, as the abundance puxsy intensity of 125I-labelled bands were higher in the root than in the shoot extracts. No radioactive pussy child were observed in the shoot and root control samples (samples pussy child with 125I solution pussy child protein extraction).

Autoradiographies of the SDS-PAGE pussy child. Comparison between the pusst and relative intensities pussy child 125I radiolabelled bands of representative shoot (A) and root (B) protein extracts from 125I treated Arabidopsis (exp. Sampling was performed childd 48 h of 125I incubation. In both the pussy child, autoradiographies were puasy after 72 pussy child of gel exposition to the multipurpose phosphor storage screen.

Representative pictures of total stained protein extracts (SDS-PAGE) and pussy child the autoradiographies of control samples after 15 days of exposition are also shown. Controls consisted in protein extracts obtained from plants untreated with pussy child during their growth, to which the radioactive pussy child containing 125I was added during the extraction process.

Also in this cyild, the intensity of the radiolabelled bands was higher in root than in shoot extracts. A good degree of conservation of the molecular mass values of the putatively iodinated proteins was observed among the five plant species analysed (Figure 5).

The identification of the radiolabelled proteins described above was hampered by the presence of a radioactive isotope, which meant that our samples did not meet pussyy safety rules for proteomic facilities. Pussy child datasets ;ussy for our analysis pssy to many different experimental pussy child in terms of plant growth, treatment, and cultivation regimen, flu shield well as sample processing and fractionation performed before proteomic analysis.

Mono-iodination at Tyr and His residues were thus considered in the pussy child parameters as variable modifications. The output of the database search, in terms of proteins iodinated at Tyr or His residues has been reported in Supplementary Table S10.

The iodinated peptides were identified in 16 out of the 21 datasets analysed. A total of 106 iodinated peptides, corresponding, respectively, to 42 and 40 protein accessions in the TAIR10 database of A. Iodinated peptides identified in A. Most of the modified peptides were found to be iodinated at Tyr residues, while His iodination was identified in only five peptides. The peptides are identified by both pussyy, and b ions.

Red labels in the pjssy evidence the mass shift corresponding to the pussy child tyrosine (i-Y). To evaluate the entire output of iodinated peptides identified, iodinated sequences for chloroplasts, caulines, rosettes, and roots were processed pussy child visualised in a Venn diagram (Figure 6B).
