Project description:The elongation growth of japonica rice (cv. Nipponbare) coleoptiles was found to be inhibited specifically by a short UV-B irradiation (e.g., 10 min) that provides a fluence as low as 1.0 μmol m-2. Here we analyzed if there is a similar response at transcriptional level using rice microarray.

Project description:Aluminum (Al) toxicity in plants is one of the primary constraints in crop production. Al³⁺, the most toxic form of Al, is released into soil under acidic conditions and causes extensive damage to plants, especially in the roots. In rice, Al tolerance requires the ASR5 gene, but the molecular function of ASR5 has remained unknown. This data establish a comparative study of miRNAome profiles in ASR5 knockdown rice plants (ssp. Japonica cv. Nipponbare) under Al stress conditions.

Project description:Cultivated rice (Oryza sativa L.) is frequently exposed to multiple stresses, including Schizotetranychus oryzae mite infestation. Rice domestication has narrowed the genetic diversity of the species, leading to a wide susceptibility. This work aimed to observe the response of two wild rice species (Oryza barthii and O. glaberrima) and two O. sativa genotypes (cv. Nipponbare and f. spontanea) to S. oryzae infestation. Surprisingly, leaf damage, histochemistry, chlorophyll concentration and fluorescence showed that the wild species present higher level of leaf damage, increased accumulation of H2O2 and lower photosynthetic capacity when compared to O. sativa genotypes under infested conditions. Infestation decreased tiller number, except in Nipponbare. Infestation also caused the death of wild plants during the reproductive stage. While infestation did not affect the weight of 1,000 grains in both O. sativa genotypes, the number of panicles per plant was affected only in f. spontanea, and the percentage of full seeds per panicle and seed length were increased only in Nipponbare. Using proteomic analysis, we identified 195 differentially abundant proteins when comparing susceptible (O. barthii) and tolerant (Nipponbare) genotypes under control and infested conditions. O. barthii has a less abundant antioxidant arsenal and is unable to modulate proteins involved with general metabolism and energy production under infested condition. Nipponbare presents high abundance of detoxification-related proteins, general metabolic processes and energy production, suggesting that, under infested condition, the primary metabolism is maintained more active compared to O. barthii. Also, under infested conditions, Nipponbare presents higher levels of proline and a greater abundance of defense-related proteins, such as osmotin, ricin B-like lectin, and protease inhibitors. These differentially abundant proteins can be used as biotechnological tools in breeding programs aiming increased tolerance to mite infestation.

Project description:WRKY45-overexpressing (WRKY45-ox) rice plants are extremely resistant to rice blast and bacterial leaf-blight diseases. To search for the genes that are potentially responsible for the strong resistance, we performed genome-wide gene expression analysis in WRKY45-ox rice. A microarray analysis using Agilent rice oligo microarray for approximately 42,000 rice genes identified 1,664 genes that are upregulated in WRKY45-ox rice compared with non-transformant rice cv. Nipponbare (NB). Analysis of the genes with altered expression in WRKY45-ox rice by a Gene ontology program (Agri GO; http://bioinfo.cau.edu.cn/agriGO/) revealed that several genes in the biosynthetic pathway for diterpenoid phytoalexins, for which anti-blast fungus activities have been reported, were upregulated in WRKY45-ox rice.

Nipponbare rice (Oryza sativa) and WRKY45-ox rice were analyzed in three biological replicates.

Project description:Global climate change increasingly challenges agriculture with flooding and salinity. Among strategies to enhance crop resilience to these stresses, we showed two mangrove strains that can enhance flooding and salinity tolerance in rice plants. Two strains massively enhanced the growth and yield of Oryza sativa cv. Nipponbare under hydroponic growth conditions with and without salt treatment. The bacteria-induced transcriptome changes in O. sativa roots related to ABA-signaling with suberin deposition in root tissues explain the altered responses of colonized rice plants to hypoxic and saline stress conditions. While enhancing yield and grain quality, bacterially colonized rice plants also show much earlier flowering, thereby massively shortening the life cycle of rice plants and opening the possibility for an additional harvest per year. These results show that microbes can be a powerful tool for enhancing the yield and resilience of rice to hypoxic and saline stress conditions.
