Cadmium (Cd) is highly toxic to living organisms. This study aimed to elucidate the regulation of gene expression in rice shoots under Cd stress. Rice plants were exposed to 0, 50, 75, 100 μmol/L CdCl 2 in hydroponic culture for 7 d. Transcriptional changes in rice shoots were examined by transcriptome sequencing techniques. A total of 2197 DEGs (987 up-regulated and 1210 down-regulated) were detected in rice shoots under the exposure of 75 μmol/L CdCl 2 . GO and KEGG enrichment analyses showed that genes encoding auxin-responsive protein IAA and peroxidase were up-regulated, while genes encoding proteins involved in signal transduction, including TIFY family, ERF and bZIP were down-regulated. Abundant ROS related terms were also identified and grouped into significantly differentially expressed GO terms, including oxidoreductase activity, catalytic activity, oxidation-reduction process, confirming the enhanced oxidative stress of Cd. Genes encoding photosystem I reaction center subunit and photosynthetic NDH subunit of luminal location were up-regulated in pathway of energy metabolism, suggesting an interference of photosynthesis by Cd stress. Our results improve the understanding of the complex molecular responsive mechanisms of rice shoots under Cd stress.

“…Maximum shoot and root dry mass production with the ESPO source was observed at greater sulfur doses relative to the other sources, especially the case for root production (35 % additional S was required when supplied as ESPO). Grant et al (2012) and Sun et al (2017) also reported this variation in production due to the physical and chemical form of sulfur fertilizer. Elemental sulfur is only taken up by plants after microbial oxidation.…”

“…Among the species in the genus Urochloa, the cultivar Piatã has favorable management characteristics, such as low stem elongation rate, producing greater leaf blade mass relative to stem, continued forage accumulation during the dry period, lower seasonality of production, and good performance under moderate to high soil fertility (EUCLIDES et al, 2009). Sulfur deficiency in soils induced by intensive agricultural and use of highly concentrated fertilizers has initiated worldwide interest in this nutient, particularly in regions with sandy soils containing low organic matter that receive high rainfall (SALVAGIOTTI;MIRALLES, 2008;SUN et al, 2017). Sulfur deficiency substantially reductes biomass production of forage plants and their quality because sulfur is associated with the production of essential cellular components, such as sulfur-containing amino acids, vitamins, acetyl-CoA, and components of photosynthetic and nitrogen metabolism (CAPALDI et al, 2015;DING et al, 2016).…”

Sulfur deficiency in soils has become a worldwide concern for agricultural production. This study aimed to evaluate the concequence of variable sulfur source and dosing on the nutritional status and production of Piatã forage in a dystrophic Ultisol. The experiment was arranged in a completely randomized block design with four replications. The 4 x 5 factorial treatments consisted of four sulfur sources (elemental sulfur pastilles [ESPA], gypsum [GY], gypsite [GI], and elemental sulfur powder [ESPO]) and five sulfur doses (0, 50, 100, 150. and 200 mg kg-1). The sulfur applications resulted in similar maximum shoot dry mass (SDM) production (16.66 to 17.69 g pot-1) with all sources. However, Piatã grass achieved maximum production in the treatments with 112 mg kg-1 of GI, 118 mg kg-1 of GY and ESPA, and 146 mg kg-1 of ESPO. The number of tillers, the leaf:stem ratio, and SPAD increased with increasing sulfur dose. The greatest increments of root dry mass (RDM) and of the tiller number were obtained with the ESPO source. Macronutrient concentrations in shoot dry mass tissue were in the order K > N > Ca > P > S > Mg. Low sulfur supply resulted in decreased Piatã grass growth with all sulfur sources tested. Differential responses were found with applications of different sulfur sources for SDM, RDM, and tillers number. The sources did not alter the leaf:stem ratio or SPAD index.

“…However, the presence of ligands including those with amine functional groups, induce solubility of CuO-NPs at neutral pH (Wang et al 2013). Recently, Kovacec et al (2017) (Sun et al 2017). It was suggested that sulphur fertilization decreases the Cu content in the root, leaf, and husk of the plant yielding higher biomass but showed higher amounts of Cu in rice grains in the form of Cu(I)-cysteine and Cu(I)-acetate.…”
