Drought susceptible rice cultivar PTT1 (Pathumthani1) was treated with drought (-72 kPa) and CPPU (N-2-(chloro-4-pyridyl)-N-phenyl urea) @ 5 mg/L at tillering and grain-filling stages. Plants were tested for the effect of synthetic cytokinin on the parameters influencing the process of photosynthesis. Exogenous spray of CPPU improved the stomatal conductance of rice leaves, which was severely reduced by drought. The abundance intensities of proteins, associated with the stomatal conductance (ZEP ...[more]

Stress response and detoxification mechanisms involved in non-target site herbicide resistance in sunflower

Project description:The objective of this study was to evaluate the role of cytochrome P450 monooxygenases (P450s) and other detoxification-related proteins in Imisun sunflower resistance. Two sunflower inbred lines were used: HA 425 and HA 89, imidazolinone (IMI)-resistant and susceptible, respectively. Growth response to imazethapyr herbicide in combination with P450s inhibitors 1-aminobenzotriazole (ABT) and piperonyl butoxide (PBO) was evaluated in 15-day-old sunflower plantlets. Roots were collected and label-free quantitation (LFQ) proteomic analysis were carried out in order to characterize plant response to IMI. Roots of 15-day-old plants treated with 0 and 3.3 µM imazethapyr were frozen in liquid nitrogen. Protein extraction was performed as described in Wu et al. (2014) from 1 g root tissue per genotype/treatment combination.

PROTEOME IMPACT ON MAIZE SILKS UNDER PRIMING STATE INDUCED BY TRICHODERMA ROOT COLONIZATION

Project description:Trichoderma species can stimulate local and distant immune responses in colonized plant tissues to prevent future pathogenic attacks. Priming of plant defenses is characterized by changes on transcriptional, metabolic, and epigenetic states after stimulus perception. We have previously investigated the transcriptional reprogramming in silk tissues from maize plants inoculated with Trichoderma atroviride and challenged with Fusarium verticillioides (Agostini et al 2019). To better understand about the molecular changes induced by T. atroviride in maize, a proteomic approach was conducted in this instance. Several proteins belonging to different metabolic categories were detected as priming involved proteins. However, we detected a very low correlation with those priming-modulated transcripts suggesting the importance of regulatory events posteriori of transcriptional stage to accomplish the final goal of blocking the pathogen entrance. Specifically, we focused on phenylpropanoid pathway; since we detected several proteins that are upregulated in priming state might explain the cell wall reinforcement and, the increase in the content of flavonoids and lignin in silks of maize plants after induced systemic resistance activation.

Large scale analysis of leaf gene expression upon treatment of apple seedlings with acibenzolar-S-methyl or water

Project description:Investigation of whole genome gene expression level changes in the youngest expanded leaves of open-pollinated Golden Delicious seedlings either sprayed with reverse osmosis water or acibenzolar-S-methyl (ASM). Treatment was performed by spraying sprayed to runoff (with a pressurized hand sprayer) with the commercial product Bion 50 WG (Syngenta, Basel, Switzerland; 50% of ASM) prepared in reverse osmosis water at a final concentration of 0.4 g/L. The youngest developped leaf of each seedling was sampled 3 days after the treatment.

The mouse microarray M22K_08_26 with B16F10 Cells untreated and treated with the compound 6,to observe over and down expression of genes involved in biological processes related to this treatment.

Project description:The mouse microarray M22K_08_26 with B16F10 Cells untreated and treated with the compound 6 [N- (p-methoxy-phenyl) -2- (p-methyl-phenyl) -3-phenoxy-azetidin-2-one], was approached to observe over and down expression of genes involved in biological processes. This experiment gives us information on its possible mechanism of action as anticancer compound. GenArise analysis results showed the over-expressed and inhibited genes by compound 6 on mouse melanoma B16F10 cells. In the range of 1.5 standard deviations of z-score, 676 genes were found down regulated and 1524 genes were overexpressed. In order to trace the biological impact of altered genes, an enrichment analysis by using online program Database for the Annotation, Visualization and Integrated Discovery (DAVID) was performed, the results showed a group of biological pathways involved to cell death, synthesis of the cytoskeleton and cell division processes.
