Project description:Purpose: The State of Rio Grande do Sul is the largest producer of peaches from Brazil. However, it still has low values of productivity when compared to other States. One of the problems associated to it this is the occurrence of drainage soils problems, which can suffer flooding situations potentially hampering the development and productivity such culture. For studies to assist in the selection of flood tolerant genotypes, it is essential to understand the physiological and molecular changes of the plants in situations of oxygen deprivation. Using Illumina Hiseq2500 we performed transcriptome analysis of leaves from ‘Capdeboscq’ (Prunus persica) and ‘Julior’ (Prunus insititia x Prunus domestica) rootstocks under flooding for 48 hours. Methods: The mRNA of Prunus spp. plants cv. Capdeboscq e Julior was generated using deep sequencing, in triplicate, using Illumina Hi-Seq 2500, for the following treatments:I) control: plants received irrigation daily until field capacity; and II) plants exposed to flood stress, maintaining a water level of approximately 3 cm above the ground. The sequence reads that passed quality filters were analyzed at the transcript level using this method: Mapping using STAR and identification of differentially expressed genes (DEGs) was performed with the edgeR (false discovery rates - FDRs of <0.05). RT–qPCR validation was performed using SYBR Green assays. Results: Flooding stress causes important high transcriptional changes in the ‘Capdeboscq’ compared to 'Julior' and this is mainly due to their sensitivity/tolerance levels. ‘Capdeboscq’ had photosynthesis as the most affected physiological process at the molecular level, showing a large number of down-regulated enriched GOs, even though it activated cellular signaling pathways under flooding. 'Julior' was more efficient in defense responses, which include the activation of flavonoid biosynthesis pathways. Conclusions: The analysis of two Prunus spp. rootstocks contrasting to the level of tolerance / sensitivity provide new insights into the process of plant flood stress tolerance.

Project description:We analyzed global transcriptional changes in both shoots and roots of root-flooded Arabidopsis seedlings by microarrays. We also interpreted the significance of the systemic communication between roots and shoots by functional classification of affected genes. We performed genetic analysis with an ethylene signaling mutant, ein2-5, to correlate systemic flooding responses with ethylene signaling. We identified a class of genes that were up- or downregulated in shoots, but not affected in roots, under hypoxic conditions. A comprehensive managing program of carbohydrate metabolism was observed, providing an example of how systemic communications might facilitate the survival of plants under flooding. A proportion of long-distance hypoxic regulation was altered in ein2-5.

Project description:We use Solanum dulcamara subjected to drought or flooding and damaged by Spodoptera exigua to analyze such interactions at multiple levels. Drought and herbivory caused comparable effects on S. dulcamara physiological response, which was reflected by a considerable overlap in S. dulcamara transcriptomic profiles. This included many defense responses and genes involved in biosynthesis of secondary metabolites that were induced by drought and herbivory but repressed by flooding. Furthermore, combination of drought and herbivory additively induced a part of these herbivore-induced responses suggesting that drought-stressed plants were more resistant. Our study provides concrete evidence of how abiotic stresses differentially affect the plant complex hormonal interactions to fine-tune plant responses to insects.

Project description:In several photovoltaic (PV) technologies, the presence of electronic defects within the semiconductor band gap limit the efficiency, reproducibility, as well as lifetime. Metal halide perovskites (MHPs) have drawn great attention because of their excellent photovoltaic properties that can be achieved even without a very strict film-growth control processing. Much has been done theoretically in describing the different point defects in MHPs. Herein, we discuss the experimental challenges in thoroughly characterizing the defects in MHPs such as, experimental assignment of the type of defects, defects densities, and the energy positions within the band gap induced by these defects. The second topic of this Review is passivation strategies. Based on a literature survey, the different types of defects that are important to consider and need to be minimized are examined. A complete fundamental understanding of defect nature in MHPs is needed to further improve their optoelectronic functionalities.

Project description:To decipher stress responses under flooding and drought as well as flooding-tolerant mechanisms in soybean, the mathematic biological approach of simulation model was applied. Furthermore, wild-type soybean with ABA treatment and flooding-tolerant mutant line, which displayed flooding tolerance, were used as the flooding-tolerant materials. Proteins acquired by gel-free/label-free proteomic technique were used for simulation model of responses under different stresses and flooding tolerant.
