Summary Drought stress seriously limits crop productivity. Although studies have been carried out, it is still largely unknown how plants respond to drought stress. Here we find that treatment can enhance the phosphorylation activity of brassinosteroid‐signaling kinase 1 (ZmBSK1) in maize ( Zea mays ). Our genetic reveal ZmBSK1 positively affects tolerance plants. localizes plasma membrane, interacts with calcium/calmodulin (Ca 2+ /CaM)‐dependent protein (ZmCCaMK), and phosphorylates...

Salinity has become a crucial environmental factor seriously restricting maize (Zea mays L.) growth, development and productivity. However, how plants respond to salt stress is still poorly understood. In this study, we report that brassinosteroid-signaling kinase gene ZmBSK1 plays significant role in response. Expression pattern analysis revealed the transcript level of was upregulated by NaCl treatment both leaves, roots, stems. Phenotypic physiological showed overexpression improved...

A suite of laser based diagnostics is used to study interactions magnetised, supersonic, radiatively cooled plasma flows produced using the Magpie pulse power generator (1.4 MA, 240 ns rise time). Collective optical Thomson scattering measures time-resolved local flow velocity and temperature across 7–14 spatial positions. The spectrum recorded from multiple directions, allowing more accurate reconstruction vectors. areal electron density measured 2D interferometry; optimisation analysis are...

A simple and efficient method for computing bandgap structures of two-dimensional photonic crystals is presented. Using the Dirichlet-to-Neumann (DtN) map unit cell, bandgaps are calculated as an eigenvalue problem each given frequency, where related to Bloch wave vector. linear matrix obtained even when medium dispersive. For composed a square lattice parallel cylinders, DtN by cylindrical expansion. This leads problems relatively small matrices. Unlike other methods based on expansions,...

A new experimental platform was developed, based on the use of supersonic plasma flow from ablation stage an inverse wire array z-pinch, for studies shocks in magnetized high energy density physics plasmas a well-defined and diagnosable 1-D interaction geometry. The mechanism generation ensures that (ReM ∼ 50, MS 5, MA 8, Vflow ≈ 100 km/s) has frozen-in magnetic field at level sufficient to affect formed by its with obstacles. It is found addition expected accumulation stagnated thin layer...

Biomass and grain yield are key agronomic traits in sorghum (Sorghum bicolor); however, the molecular mechanisms that regulate these not well understood. Here, we characterized biomass 1 (by1) mutant, which displays a dramatically altered phenotype includes reduced plant height, narrow stems, erect leaves, abnormal floral organs. Histological analysis suggested phenotypic defects mainly caused by inhibited cell elongation organ development. Map-based cloning revealed BY1 encodes...

Transmission and morbidity induced by Schistosoma japonicum were evaluated in 825 individuals undergoing periodic treatment with praziquantel on Jishan island, Jiangxi Province, the People's Republic of China. Eggs S. found stools 39·4% population; 70% those infected less than 20 years age. Hepatomegaly greater 3 cm midsternal line was detected physical examination ultrasonography 75% 90% individuals, respectively, regardless infection status.

Hepatic fibrosis due to schistosomiasis japonica was examined by ultrasonography in a cross-sectional community study of 825 individuals on Jishan Island, Jiangxi Province, China. The prevalence active infection 39·4% with peak the 10–19·9 years age group followed significant decline. A similar pattern observed for intensity infection. hepatomegaly midsternal line ⩾6 cm peaked at 60% fourth decade and remained elevated. progressive increase severity hepatic periportal age, advanced peaking...

Drought stress during the reproductive period of cereal crops leads to significant yield reductions, therefore, exploring effective methods improve tolerance post-anthesis drought is necessary. Pot experiment was carried out investigate effects pre-drought priming on physiological characteristics and grain with at post-anthesis. Moderate water deficits (60–65% field capacity) were imposed prime wheat plants either tillering or jointing stages, while severe (40–45% applied filling stage. The...
