BACKGROUND In plants, ERF genes participate in a variety of regulatory pathways, such as plant growth and biotic and/or abiotic stress responses. Although the genome of Chinese white pear ('Dangshansuli') has been released, knowledge regarding the ERF family in pear, such as gene functions, evolutionary history and expression patterns, remains limited. RESULTS In our study, a total of 155 mem...

In this study, an air heated solar collector (AHSC) dryer was designed to determine the drying characteristics of the pear. Flat pear slices of 10 mm thickness were used in the experiments. The pears were dried both in the AHSC dryer and under the sun. Panel glass temperature, panel floor temperature, panel inlet temperature, panel outlet temperature, drying cabinet inlet temperature, drying ca...

Cattle consuming low-quality forages (LQF) require protein supplementation to increase forage utilization via ruminal fermentation. Biofuel production from algal biomass results in large quantities of postextraction algal residue (PEAR), which has the potential to elicit LQF utilization responses similar to cottonseed meal (CSM); however, its effect on ruminal bacterial communities is unknown. ...

the fruit set rate and yield of pear are commonly low due to insufficient pollination, as the species is unattractive to honeybees. to improve honeybee foraging behavior for the pollination of dangshan pear (pyrus bretschneideri cv. dangshansuli), nine methods were used to attract bees. a control treatment of colonies was fed with normal sugar syrup, while six other treatments were fed using su...

A genome-wide identification and cloning of CaM genes in pear was conducted and in compared with Arabidopsis that indicated a conserved expansion of CaM genes in pear, and PbCaMs and AtCaMs had a similar distribution of cis-elements and expressions in response to salt and osmotic stress. In particular, PbCaM1 and PbCaM3 were both significantly upregulated in response to salt and osmotic stress ...

The general purpose of this study was to examine the efficiency of the Precision Efficacy Analysis for Regression (PEAR) method for choosing appropriate sample sizes in regression studies used for precision. The PEAR method, which is based on the algebraic manipulation of an accepted cross-validity formula, essentially uses an effect size to determine the subject-to-variable ratio appropriate f...

ABSTRACT Phytosanitary concerns about fire blight prohibit export of U.S.-grown pears to some countries without this disease. To examine these concerns, we evaluated the potential for co-occurrence of Erwinia amylovora with mature, symptomless winter pear fruit by inoculation experiments and by survey of commercial orchards. Immature pear and apple fruit were inoculated in orchards with E. amyl...

MOTIVATION The Illumina paired-end sequencing technology can generate reads from both ends of target DNA fragments, which can subsequently be merged to increase the overall read length. There already exist tools for merging these paired-end reads when the target fragments are equally long. However, when fragment lengths vary and, in particular, when either the fragment size is shorter than a si...
