Prunus persica has been proposed as a genomic model for deciduous trees and the Rosaceae family. Optimized protocols for RNA isolation are necessary to further advance studies in this model species such that functional genomics analyses may be performed. Here we present an optimized protocol to rapidly and efficiently purify high quality total RNA from peach fruits (Prunus persica). Isolating h...

Although contemporary climate has been identified as one of the major determinants large-scale species diversity patterns, its effect on greatly varies among clades. Understanding drivers variation in diversity–climate relationships (DCRs) across clades, which is critical for developing general mechanisms underlying effects remains a current challenge. Using newly compiled distribution data 914...

Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysiphaceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to determine evolutionary relationships between Podosphaera and its host plants, we...

The response of soil properties to vegetation types is still not well understood and the relationship between vegetation types and soil properties has not been quantified in highland grasslands. A field experiment was conducted in highland grassland of the Loess Plateau in China to study the distribution of soil properties under different vegetation. 22 plant communities totaling 17 species tha...

Background. The phytohormone jasmonates (JAs) regulate fundamental plant processes; such as the anthocyanin accumulation during ripening of strawberry, a non-climacteric fruit model. Jasmonoylisoleucine (JA-Ile), one of the bioactive JA molecules, mediates binding of the JAZ repressor protein to COI1, an F-box protein forming the SCF ubiquitin E3 ligase complex, in Arabidopsis. The COI1-JA-Ile-...

Peach (Prunus persica L.) is a highly valuable crop species and is recognized by molecular researchers as a model fruit for the Rosaceae family. Using whole-genome sequencing data generated from 129 peach accessions, here we perform a comprehensive genome-wide association study for 12 key agronomic traits. We show that among the 10 qualitative traits investigated, nine exhibit consistent and mo...

The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introd...

extracts obtained from the petals of rosa damascena (rosaceae) are used in iranian folk medicine as remedies for the treatment of some inflammatory diseases. in this study the hydroalcoholic extract and essential oil of the plant were investigated for its possible anti-inflammatory and analgesic activities. the extract was administered at the doses (p.o.) of 250, 500 and 1000?mg/kg and the dose...
