栽培陆地棉广泛种植于世界各地,是最重要的天然纤维来源,纤维品质直接决定了其经济价值。国内外棉花育种家开展了广泛的远缘杂交工作,将许多稀有的重要基因转移到栽培陆地棉中提高纤维品质,但并未对这些基因进行深入研究。本研究分析了超过3000份棉花种质资源,总计调查了近80000个纤维品质数据,全面剖析和评估了现存陆地棉种质资源中纤维品质相关的优异位点,并从远缘杂交渐渗系中鉴定到两个新的与纤维品质密切关联的...
Activities of digestive enzymes and main histological characteristics of the intestine were investigated in larvae of three salmonid species (Coregonus maraena, C. atterensis, Thymallus thymallus), o...
Extensive soil sampling and screening assessment of ecosystem risks combined with a multidimensional statistical analysis were used to estimate and spatially characterize the ecosystem risks stemming ...
Severe symptoms of root rot on sugar beet have been observed in Poland and Germany since 2001. The symptom classification suggested girth scab as it was mistakenly classified on the basis of current c...
The present study was carried out to evaluate the anti-obesity effect of different concentrations of extracts of hot air-dried ramie leaf (HR) and freeze-dried ramie leaf (FR) in 3T3-L1 cells and pig ...
Probiotic administration is an alternative to antibiotic supplementation in pig management. However, potential probiotic microorganisms included in foods must be well defined and correctly named, on t...
A horse suffering from an undetected hoof bone fracture was diagnosed three weeks after injury. The formation of callus tissue was detected at the fracture site. Standard orthopaedic screw application...
The rain erosivity R-factor is one of the main parameters in the Universal Soil Loss Equation (USLE). This paper describes the procedure used to update, differentiate and regionalize the rainfall eros...
The phenological stages, flower characteristics, shoot growth and flower bud differentiation of sweet cherries, cv. Hongdeng and Van, were investigated in different climatic zones in China, subtropica...
The aim of this study was to examine the specificity of primers designed to detect the insertion element IS901 commonly used in differentiation of Mycobacterium avium complex strains. This study shows...
Restriction fragment length polymorphism (RFLP) analysis of open reading frame 5 was developed for typing of Czech strains of porcine reproductive and respiratory syndrome virus (PRRSV). The set of re...
Fifty-one grapevine cultivars registered in the Czech Republic were a subject of RAPD analysis. Nine grapevine varieties which were supposed to be genetically distant, were analysed by means of 120 Op...
Background: MicroRNAs are endogenous non-coding RNAs with important regulatory and cell fate functions. Many studies have shown that several microRNAs are obviously up-regulated during stem cell diffe...
Light quality and quantity of the environment, where lettuce seedlings were grown, affected the mesophyll tissue and the shoot formation in cotyledons excised and cultured in vitro. When cultured on M...
The effect of corticosterone (CTC) at low and high concentrations on proliferation and differentiation was studied in chick myoblasts. Chick myoblasts were incubated with low (3ng/ml) and high (30ng/m...
