Background and Aims As with other crop species, Al tolerance in rice (Oryza sativa) is widely different among cultivars, the mechanism for unknown.The Ca 2+ -displacement hypothesis, that is, displaces from critical sites root apoplast, was predicted to be essential causing toxicity cultivars.If displacement of an cause rice, may show same trend as toxicities elements such Sr Ba are effective displacing Ca.Methods The interactive effects Al, Ca, on elongation cultivars tolerances were...

Abstract Al3+ and H+ toxicities predicted to occur at moderately acidic conditions (pH [water] = 5–5.5) in low-Ca soils were characterized by the combined approaches of computational modeling electrostatic interactions ions root plasma membrane (PM) surface molecular/physiological analyses Arabidopsis (Arabidopsis thaliana). Root growth inhibition known hypersensitive mutants was correlated with computed {Al3+} PM ({Al3+}PM); alleviated increased Ca, which also reduced {Al3+}PM cellular Al...

Aluminium (Al) is a phytotoxic element affecting the growth and yield of many crop plants, especially in tropics. Yet, some plants are able to accumulate high levels Al. The monogeneric family Symplocaceae represents an Al accumulating including tropical evergreen species with their above ground plant tissues. It unclear, however, whether accumulation also characterises temperate Symplocos, or not uptake has beneficial effect. Here, we investigate if temperate, deciduous Symplocos paniculata...

Ionomics is the study of elemental accumulation in living organisms using high-throughput profiling. In present study, we examined ionomic responses to nutrient deficiency maize grown field long-term fertilizer trials. Furthermore, available elements soils were analyzed investigate their changes under treatment and relationships between plant soil. Maize was cultivated a with following five treatments: complete fertilization, fertilization without nitrogen, phosphorus, potassium, no...

Background: Sevoflurane is generally the preferred anesthetic agent for general anesthesia in pediatric patients, due to its rapid induction and recovery characteristics. However, it has been recognized that a major complication emergence agitation when awakening from anesthesia.

The transcription factor sensitive to proton rhizotoxicity 1 (STOP1) regulates multiple stress tolerances. In this study, we confirmed its involvement in NaCl and drought tolerance. root growth of the T-DNA insertion mutant STOP1 (stop1) was NaCl-containing solidified MS media. Transcriptome analysis stop1 under revealed that several genes related salt tolerance, including CIPK23. Among all available homozygous mutants suppressed stop1, only cipk23 showed a NaCl-sensitive phenotype...
