Abstract As a major crop in the world, sustainable development of rice is often severely restricted by bacterial blight. Breeding crops with resistance an efficient way to control However, enhancing incurs fitness penalty, making it challenging simultaneously increase blight and yield potential. In this study, found that OsGRF6 , besides being high‐yield gene, can significantly improve resistance. Compared wild‐type, lesion lengths transgenic material overexpressing are reduced after...

Selenium (Se) is a trace element that essential for human health. Daily dietary Se intake governed by the food chain through soil-plant systems. However, cadmium (Cd) content tends to be excessive in seleniferous soil, which and Cd have complex interactions. Therefore, it great challenge grow crops containing appreciable amounts of but low Cd. We compared effects five Se-transforming bacteria on uptake Brassica rapa L. native Cd-polluted soil. The results showed three Se-oxidizing (LX-1,...

Antimony (Sb) is toxic to ecosystems and potentially public health via its accumulation in the food chain. Bioavailability toxicity of Sb have been reduced using various methods for remediation Sb-contaminated soil most studies. However, by microbial agents has rarely evaluated. In this study, we evaluated potential use Comamonas testosteroni JL40 bioremediation Sb-contamination. Strain immobilized more than 30 % Sb(III) solution oxidized over 18 Sb(V) detoxification. Meanwhile, strain...

A Gram-negative and rod-shaped bacterial strain, X-65T, isolated from desert soil of Xinjiang, China, was subjected to phenotypic phylogenetic studies. On the basis 16S rRNA gene sequence analyses, isolate showed closest relationship members genera Chryseobacterium (92.4–95.4 % similarity), Cloacibacterium (94.0 %), Sejongia (93.9 %) Elizabethkingia (93.8 Riemerella columbina LMG 11607T (93.3 %). The strain differed its neighbours by swimming motility in liquid cultures presence long...

A Gram-stain-negative, rod-shaped bacterium, strain H23 T , was isolated from farmland soil sampled in Enshi City, Hubei Province, PR China. The isolate grew optimally at 28–32 °C, pH 8.0 and with 0.5 % (w/v) NaCl. Based on the results of 16S rRNA gene sequence phylogenetic analyses, belonged to genus Luteimonas highest degree similarity cucumeris Y4 (97.41 %). DNA G+C content 65.88 mol%. average nucleotide identity Genome-to-Genome Distance Calculator also showed low relatedness (below 95...

Global warming poses a threat to rice production. Breeding heat-tolerant is an effective and economical approach addressing this challenge. African valuable genetic resource for developing crops due its intricate mechanism adapting high temperatures. Oryza longistaminata, wild species widely distributed in Africa, may harbor even richer gene pool heat tolerance, which remains untapped. In study, we identified three QTLs from O. longistaminata at the seedling stage. Among these, qTT4 qTT5 are...

Arsenic (As) is widely present in the environment, and virtually all bacteria possess a conserved ars operon to resist As toxicity. High selenium (Se) concentrations tend be cytotoxic. Se has an uneven regional distribution added mitigate contamination Se-deficient areas. However, bacterial response exogenous remains poorly understood. Herein, we found that As(III) presence was crucial for Enterobacter sp. Z1 develop resistance against Se(IV). Se(IV) reduction served as detoxification...

A novel Gram-stain-negative, curved rod-shaped, motile and chitin-degrading strain, designated CD1 T , was isolated from crawfish pond sediment in Caidian District (30° 58′ N 114° 03′ E), Wuhan City, Hubei Province, PR China. Growth of this strain observed at 15–40°C (optimum between 28 30 °C), pH 7.0–9.0 7.0 8.0) with 0–1 % (w/v) NaCl 0 %). With respect to the 16S rRNA gene sequences, had highest similarity (96.91–97.25 %) four type strains genera ‘ Chitinolyticbacter ’ Chitiniphilus within...

Enzyme linked immunosorbent assays of three Aspergillus species have been developed. Laying hens were immunized with the exoantigens from Asp. flavus, ochreaus and versicolor. All test chickens except for one produced antisera raised against exoantigens. The production process ELISA titer analysed. Fourteen days after first injection, began to produce largely, on 35th day reached peak, maintained a stable level until 42nd day. maximum versicolor was 1:8,000, 1:10,000 1:10,000, respectively....

Bacterial strain H33T was isolated from tobacco plant soil and characterized using a polyphasic taxonomy approach. Strain Gram-stain-negative, rod-shaped, non-motile strictly aerobic bacterium. Phylogenetic analyses based on 16S rRNA gene sequences coding of the up-to-date bacterial core set (92 protein clusters) indicated that belongs to genus Sphingobium. showed highest sequence similarity Sphingobium xanthum NL9T (97.2%) 72.3-80.6 % average nucleotide identity 19.7-29.2 digital DNA-DNA...

Two-dimensional (2D) niobium silicon telluride (Nb<sub>2</sub>SiTe<sub>4</sub>) was recently proposed as a promising candidate in infrared detector, photoelectric conversion, polarized optical sensor and ferroelastic switching application due to its narrow bandgap, long-term air stability, high carrier mobility, etc. However, the in-plane strains interfacial defects induced by lattice misfits between functional layers are harmful 2D heterojunction nanodevice...

A Gram-negative, aerobic bacterial strain, designated LX-88T, was isolated from seleniferous soil in Enshi, Hubei Province, PR China. Strain LX-88Toxidized elemental selenium to selenite, and produced carotenoids but not bacteriochlorophyll. The isolate grew optimally at 28 °C, pH 8.0 with 0.5 % (w/v) NaCl. Phylogenetic analysies of the organism's 16S rRNA core gene set sequences indicated that LX-88T belongs genus Croceibacterium, has highest degree sequence similarity Croceibacterium soli...
