Project description:Tomato, a Strategy I model plant for Fe deficiency, is an important economical crop. The transcriptional responses induced by Fe deficiency in tomato roots were previously described (Zamboni et al., 2012). The changes in trascriptome caused by the supply of Fe to plants starved fro 1 week were described in relation to the different nature of chelating agents (Fe-WEHS, Fe-CITRATE and Fe-PS).

The changes in trascriptome caused by the supply of Fe to plants starved fro 1 week were described in relation to the different nature of chelating agents (Fe-WEHS, Fe-CITRATE and Fe-PS). Transcriptional profile obtained by roots (27-d) of 21-d-old tomato plants starved of iron (0 μM Fe-EDTA) for 1 week and supplied for 1 h with 1 μM of Fe as Fe-WEHS (supply_Fe_WEHS), Fe citrate (supply_Fe_CITRATE) and Fe-PS (supply_Fe_PS). Tomato plants were hydroponically grown in all three case of Fe supply. Three different biological replicates were used for each sample repeating the experiment three times. All samples were obtained pooling roots of six plants (27-d-old).

Project description:Iron (Fe) deficiency is a yield-limiting factor for a variety of field crops across the world and generally results from the interaction of limited soil Fe bioavailability and susceptible genotype cultivation. Tomato, a Strategy I, model plant for Fe deficiency, is an important economical crop. Tomato responses in order to improve Fe uptake are based on acidification of rhizosphere, reduction of Fe3+ to Fe2+ and transport of Fe2+ into the cells.

Transcriptional profile obtained by roots (27-d) of 21-d-old tomato plants starved of iron for an additional week was compared with the transcriptional profile obtained for roots (27-d) of 21-d-old tomato plants grown for an additional week at 100 M-NM-<M Fe. Tomato plants were hydroponically grown in both cases. Three different biological replicates were used for each sample repeating the experiment three times. All samples were obtained pooling roots of six plants (27-d-old).

Project description:a novel orphan peptide, IRON-REGULATED PROTEIN1 (IRP1) that is rapidly induced by Fe deficiency and improves growth on Fe-deplete media. In Arabidopsis, ectopic expression of IRP1 affected the activity of several genes involved in Fe acquisition and homeostasis, causing a dramatic increase of Fe in leaves and enhanced seed Fe loading. Heterologous expression of IRP1 in tomato plants resulted in increased Fe levels in fruits. Integration of AtIRP1 into the genome of crop plants may represent a novel strategy for Fe biofortification.

Roots and shoots were collected with 3 biological replicates.

Project description:Background: Witches’ broom disease of Mexican lime (Citrus aurantifolia L.), which is caused by the phytoplasma “Candidatus Phytoplasma aurantifolia”, is a devastating disease that results in significant economic losses. Plants adapt to abiotic stresses by regulating gene expression at the transcriptional and post-transcriptional levels. MicroRNAs (miRNAs) are a recently identified family of molecules that regulate plant responses to environmental stresses through post-transcriptional gene silencing. Methods: Using a high-throughput approach to sequence small RNAs, we compared the expression profiles of miRNAs in healthy Mexican lime trees and in plants infected with “Ca. Phytoplasma aurantifolia”. Results: Our results demonstrated the involvement of different miRNAs in the response of Mexican lime trees to infection by “Ca. Phytoplasma aurantifolia”. We identified miRNA families that are expressed differentially upon infection with phytoplasmas. Most of the miRNAs had variants with small sequence variations (isomiRs), which are expressed differentially in response to pathogen infection. Conclusions: It is likely that the miRNAs that are expressed differentially in healthy and phytoplasma-infected Mexican lime trees are involved in coordinating the regulation of hormonal, nutritional, and stress signalling pathways, and the complex interactions between them. Future research to elucidate the roles of these miRNAs should improve our understanding of the level of diversity of specific plant responses to phytoplasmas.

Project description:Lysine acetylation and succinylation are post-translational modifications of proteins, and have been shown to play roles in plant response to pathogen infection. Phytoplasma infection can directly alter multiple metabolic processes in Paulownia and lead to Paulownia witches’ broom (PaWB), the major cause of Paulownia mortality worldwide. To explore the extent and function of lysine acylations during phytoplasma infection, we investigated global proteome, acetylome, and succinylome of phytoplasma-infected Paulownia tomentosa seedlings. In total, we globally yield 8963 proteins, 2893 acetylated, and 1271 succinylated proteins. Among them, 425 substrates were simultaneously acetylated and succinylated. Comparative analysis revealed that 276 proteins, 546 acetylated proteins and 5 succinylated proteins were associated with PaWB. Our results suggested that acetylation may be more important than succinylation in response to phytoplasma infection. Enzymatic assays showed that acetylation modified the activities of protochlorophyllide reductase and RuBisCO in phytoplasma-infected seedlings. On the basis of these results, a model to elucidate the molecular mechanism responses to PaWB was proposed and this research offer a resource for functional studies on the effects of acetylation on protein function.
