Abstract Most commercial orchards of mandarins in Paraná grow ‘Ponkan’ trees predominantly grafted on ‘Rangpur’ lime. The limited genetic diversity citrus for both scion and rootstock may promote pest disease outbreaks. late season ‘Montenegrina’ willowleaf mandarin has high potential orchard diversification because its higher productivity better fruit quality. Therefore, this study assessed th...

studies have shown that oxygenated compounds and tss/ta are important for beverage and food industries. it seems that citrus rootstocks have a profound influence on oxygenated compounds and tss/ta. the aim of this research is to identify rootstock that can synthesize the maximum level of oxygenated compounds and tss/ta. peel oil was extracted using mechanical presses and eluted using n-hexane. ...

The effect of gibberellins (GA) on internode transcriptome was investigated in transgenic Carrizo citrange (Citrus sinensis x Poncirus trifoliata) plants overexpressing endogenous CcGA20ox1 (encoding a GA biosynthetic gene), and in non-transformed explants treated with GA(3), using a citrus cDNA microarray. Substantial modulation of gene expression was found in sense CcGA20ox plants. Extensive ...

Drought and heat stresses are two of the most frequent environmental factors that take place simultaneously in the field constraining global crop productivity. Metabolism reconfiguration is often behind the adaptation of plants to adverse environmental conditions. Carrizo citrange and Cleopatra mandarin, two citrus genotypes with contrasting ability to tolerate combined heat and drought conditi...

Drought and high temperatures are two major abiotic stress factors that often occur simultaneously in nature, affecting negatively crop performance and yield. Moreover, these environmental challenges induce oxidative stress in plants through the production of reactive oxygen species (ROS). Carrizo citrange and Cleopatra mandarin are two citrus genotypes with contrasting ability to cope with the...

Reduced semantic fluency performances have been reported in the preclinical phase of Alzheimer's disease (AD). To investigate the cognitive processes underlying this early deficit, this study analyzed the verbal production of predemented subjects for the animals category with the qualitative parameters related to clustering (i.e. the ability to generate words belonging to semantic subcategories...

A number of techniques that extract data or study user needs and requirements, such as questionnaires, interviews, focus group discussions, and heuristic observations, have been widely adopted by designers and are mentioned in consumer study, marketing research, and product design literature (Hayes, 1992; Urban & Hauser, 1993; Nielsen, 1993). Understanding and interpreting the user’s unexpresse...

Troyer syndrome is an autosomal recessive hereditary spastic paraplegia (HSP) caused by frameshift mutations in the SPG20 gene that results in a lack of expression of the truncated protein. Spartin is a multifunctional protein, yet only two conserved domains--a microtubule-interacting and trafficking domain and a plant-related senescence domain involved in cytokinesis and mitochondrial physiolo...
