BACKGROUND Lipid transfer proteins (LTP) are pan-allergens in plant derived foods that have been also detected in several pollens. The observed cross-reactivity between pollen and plant-food LTPs has led to hypothesize that primary sensitisation to this allergen may occur through the airways. OBJECTIVE The present study looked at the prevalence of hypersensitivity to different L TP-containing...

Mutation rates and recombination rates vary between species and between regions within a genome. What are the determinants of these forms of variation? Prior evidence has suggested that the recombination might be mutagenic with an excess of new mutations in the vicinity of recombination break points. As it is conjectured that domesticated taxa have higher recombination rates than wild ones, we ...

Host-parasite relationships of Criconemella xenoplax and C. ornata on Nemaguard peach and common bermudagrass were determined in the greenhouse. Criconemella xenoplax reproduced on peach and reduced root volume, height, and dry stem weight after 6 months, compared with the noninfested check. Numbers of C. ornata did not increase on peach or influence peach growth, but they did reduce dry top we...

Amygdalin contents of the seeds, endocarps, and mesocarps from three peach cultivars (i.e., Stone Peach, Hikawa Hakuho, and Bakhyang) were measured at three stages of fruit development (stone-hardening, fruit enlargement, and ripening). The peach samples were dried and defatted with a Soxhlet apparatus, reflux extracted with methanol, and analyzed using reverse phase high-performance liquid chr...

This paper presents a new framework for modeling light interception by isolated trees which makes it possible to analyze the in uence of structural tree organization on light capture. The framework is based on a multiscale representation of the plant organization. Tree architecture is decomposed into a collection of components representing clusters of leaves at di erent scales in the tree crown...

Trials were established at Aula Dei Experimental Station (EEAD-CSIC, Zaragoza, Spain) to assess graft compatibility between peach cultivars [Prunus persica (L.) Batsch] and new Prunus spp. rootstocks or selections. Peach cvs. Catherina and Tebana and nectarine cvs. Big Top and Summergrand were grafted on peach seedlings, plum rootstocks, almond x peach hybrids, and other interspecific rootstock...

Methods Forty-six peach allergic patients confirmed as positive by skin test, ImmunoCAP IgE and/or a double-blind placebocontrolled food-challenge (DBPCFC) were included. After one year of treatment we evaluated peach tolerance with DBPCFC using 5, 40, and 120 g of fresh peach with a mixture of yogurt, orange juice, coffee dried, coconut, and oatmeal flakes. Placebo meals consisted of the same ...

Climate change projections predict warmer and drier conditions. In general, moderate to severe water stress reduce plant vegetative growth and leaf photosynthesis. However, vegetative and reproductive growths show different sensitivities to water deficit. In fruit trees, water restrictions may have serious implications not only on tree growth and yield, but also on fruit quality, which might be...

Host range assessment for emerging invasive insects is a vital step toward fully defining the issues insect may pose. Spotted lanternfly (SLF) an species that rapidly expanding its presence in United States. The primary hosts facilitating this spread are tree of heaven, plant from SLF’s native range, and economically important winegrape. Black walnut also implicated as common host plant. This s...
