The cultivated apple (Malus domestica) is one of the most important fruit crops cultivated in different regions of the world including Iran. For production and breeding of high quality apple, the knowledge of genetic diversity of the cultivated apples  is  necessary. Therefore we studied genetic diversity of 25 genotypes by using ISSR molecular markers. In present study, ten ISSR primers produc...

Velvet longhorned beetle Trichoferus campestris (Faldermann) (Coleoptera: Cerambycidae) is native to Asia. It reported be polyphagous in its range, but hosts have not been screened introduced range the United States. We conducted choice and no-choice host experiments. For assays, gravid T. oviposited freely on cut branches of four tree species: Juglans nigra, Malus domestica, Acer saccharum, Pi...

The new-shoot-growing stage is an important period of apple tree nutrition distribution. The objective of this study is to provide technical support for apple tree nutrition diagnosis by constructing quantitative evaluation models between the apple leaf nitrogen content during the new-shoot-growing stage and characteristic spectral parameters. The correlation coefficients between the original s...

In unearthing the genetic history of human populations, the recent pace of discovery has been so rapid that we can lose sight of the impact made by a single paper. In a 1987 Nature article, Rebecca Cann and her co-workers, Mark Stoneking and the late Allan Wilson, painstakingly analyzed mitochondrial DNA purified from placentas that had been collected from women of many different ancestral orig...

Seasonal changes in photosynthesis of apple trees (Malus domestica Borkh.) were monitored to examine the effect of source-sink interactions on photosynthesis and photorespiration. Elevated photosynthetic rates were observed during two periods of the growing season and correlated with the fruiting process. The first period of increased photosynthetic rates was during the bloom period, when spur ...

Fire blight, caused by epiphytotic gram-negative bacteria Erwinia amylovora, is the most destructive bacterial disease of apple (Malus spp.). Genetic mechanisms fire blight resistance have mainly been studied using traditional biparental quantitative trait loci (QTL) mapping approaches. Here, we use large-scale historic shoot and blossom data collected over multiple years genotyping-by-sequenci...
