Heat shock transcription factors (Hsfs) are the central regulators of heat (HS) stress response in all eukaryotic organisms. HsfA2 is one Arabidopsis class A Hsfs, and induction expression to HS highest among 21 Hsfs. In this study, it reported that basal acquired thermotolerance was significantly enhanced high-level HsfA2-overexpressed transgenic lines (El2Omega::HsfA2) comparison with wild-type plants. By contrast, dominant negative mutants (El2Omega::HsfA2DeltaC264) plants displayed...
Significance Grain weight is an important crop yield component; however, its underlying regulatory mechanisms are largely unknown. Here, we identify a grain-weight quantitative trait locus (QTL) in rice encoding new-type GNAT-like protein that harbors intrinsic histone acetyltransferase activity (OsglHAT1). Elevated OsglHAT1 expression enhances grain and by enlarging spikelet hulls via increasing cell number accelerating filling, increases global acetylation levels of H4. Our findings reveal...
Abstract Chlorophyll (Chl) degradation occurs during leaf senescence, embryo degreening, bud breaking, and fruit ripening. The Chl catabolic pathway has been intensively studied nearly all the enzymes involved are identified characterized; however, molecular regulatory mechanisms of this largely unknown. In study, we performed yeast one-hybrid screening using a transcription factor cDNA library to search for factors controlling expression genes. We ANAC046 as common regulator that directly...
Abstract Plasticity of root growth in response to environmental cues and stresses is a fundamental characteristic land plants. However, the molecular basis underlying regulation under stressful conditions poorly understood. Here, we report that rice nuclear factor, RICE SALT SENSITIVE3 (RSS3), regulates cell elongation during adaptation salinity. Loss function RSS3 only moderately inhibits normal conditions, but it provokes spontaneous swelling, accompanied by severe inhibition, saline...
The plant hormone jasmonate and its conjugates (JAs) have important roles in growth control, leaf senescence defense responses against insects microbial attacks. JA biosynthesis is induced by several stresses, including mechanical wounding, pathogen attacks, drought salinity stresses. However, the of JAs under abiotic stress conditions are unclear. Here we report that increased expression Cyt P450 family gene CYP94C2b enhanced viability rice plants saline conditions. This encodes an enzyme...
SmFe12-based compounds have been considered as promising candidates for next generation permanent magnet materials because of their excellent intrinsic hard magnetic properties with a minimum usage rare earth elements. However, realizing high coercivity in anisotropic microstructure is big challenge, which hinders practical applications. In this work, novel granular Sm(Fe0.8Co0.2)12 sufficiently large (µ0Hc) 1.2 T and remanent magnetization 1.50 demonstrated thin films prepared by...
The mitogen-activated protein kinase (MAPK) cascade is involved in responses to biotic and abiotic stress plants. In this study, we isolated a new MAPK, NtMPK4, which tobacco homolog of Arabidopsis MPK4 (AtMPK4). NtMPK4 was activated by wounding along with two other wound-responsive MAPKs, WIPK SIPK. We found that salicylic acid-induced (SIPKK), has been as an SIPK-interacting MAPK kinase. activity-suppressed tobacco, wound-induced expression jasmonic acid (JA)-responsive genes inhibited....
Dehydroascorbate reductase (DHAR) is a key component of the ascorbate recycling system. Three functional DHAR genes are encoded in Arabidopsis genome. Ozone exposure increased expression cytosolic (cytDHAR) gene alone. We characterized an mutant with deficient cytDHAR. The completely lacked cytDHAR activity and was highly ozone sensitive. amounts total glutathione were similar both lines, but amount apoplastic 61.5% lower. These results indicate that ascorbate, which generated through...
Ozone produces reactive oxygen species and induces the synthesis of phytohormones, including ethylene salicylic acid. These phytohormones act as signal molecules that enhance cell death in response to ozone exposure. However, some studies have shown acid can instead decrease magnitude ozone‐induced death. Therefore, we studied defensive roles against ozone. Unlike wild‐type, Col‐0, Arabidopsis mutants deficient signaling ( ein2 ) or biosynthesis sid2 generated high levels superoxide...
Plant growth and development are sustained by continuous cell division in the meristems, which is perturbed various environmental stresses. For maintenance of meristematic functions, it essential that be coordinated with differentiation. However, unknown how proliferative activities meristems coordination between differentiation maintained under stressful conditions. Here we show a rice protein, RSS1, whose stability controlled cycle phases, contributes to vigour cells viability salinity...
To clarify the processes involved in plant immunity, we have isolated and characterized a single recessive Arabidopsis mutant, cad1 (constitutively activated cell death 1), which shows phenotype that mimics lesions seen hypersensitive response (HR). This mutant spontaneously expression of pathogenesis-related (PR) genes, leading to 32-fold increase salicylic acid (SA). Inoculation plants with Pseudomonas syringae pv tomato DC3000 mutation results restriction bacterial growth. Cloning CAD1...
Ozone (O3), a major photochemical oxidant, induces leaf injury concomitant with salicylic acid (SA) synthesis. In pathogen-infected leaves, SA is synthesized via two pathways, involving phenylalanine or isochorismate. biosynthesis under O3 fumigation not well understood. When we applied 14C-labeled benzoic (a precursor of in the pathway phenylalanine) to O3-exposed tobacco it was effectively metabolized SA. However, activity and mRNA level isochorismate synthase (ICS) were increased....
Abstract Conferring drought resistant traits to crops is one of the major aims current breeding programs in response global climate changes. We previously showed that exogenous application acetic acid roots various plants could induce increased survivability under subsequent stress conditions, but details metabolism exogenously applied acid, and nature signals induced by its application, have not been unveiled. In this study, we show rice rapidly induces jasmonate signaling upon resulting...
Unmanned aerial vehicles (UAVs) are one of the most effective tools for crop monitoring in field. Time-series RGB and multispectral data obtained with UAVs can be used revealing changes three-dimensional growth. We previously showed using a rice population our regular cultivation protocol that canopy height (CH) parameters extracted from time-series useful predicting manually measured traits such as days to heading (DTH), culm length (CL), aboveground dried weight (ADW). However, whether CH...
Unmanned aerial vehicles (UAVs) are popular tools for high-throughput phenotyping of crops in the field. However, their use evaluation individual lines is limited crop breeding because research on what UAV image data represent still developing. Here, we investigated connection between shoot biomass rice plants and vegetation fraction (VF) estimated from high-resolution orthomosaic images taken by a 10 m above field during vegetative stage. Haplotype-based genome-wide association studies...
The effect of V on the phase stability and intrinsic magnetic properties SmFe12-xVx (0 ≤ x 1.9) thin films, bulk (x = 1.5 2) are investigated. It is found that help to stabilize ThMn12-type by decreasing lattice parameters c c/a ratio up its solid solubility limit 1.4. Above this limit, formation Sm-rich has been observed in microstructure. Interestingly, Curie temperature (Tc) anisotropy field (μ0Ha) do not exhibit same trend with magnetization (μ0Ms) where increasing enhances two...
In plants, salicylic acid (SA), a molecule important for resistance to pathogens, is synthesized from phenylalanine or isochorismate. Although SA reportedly via the isochorismate pathway in pathogen-infected Arabidopsis, predominant tobacco has not been known. To determine tobacco, we studied gene expression and enzyme activity of ammonia-lyase (PAL) synthase (ICS) leaves infected with Tobacco mosaic virus (TMV). Two days after TMV inoculation, necrotic lesions had appeared, levels SA, PAL...
